MARKET VOLATILITY ANSLYSIS AND FINANCIAL STOCK
RETURN VOLATILITY MODELING BY SYMMETRIC AND
ASYMMETRIC GARCH - EVIDENCE FROM FINANCIAL
INDUSTRY OF HO CHO MINH STOCK EXCHANGE
ABSTRACT
This paper empirically examines the symmetric and asymmetric GARCH models in
stock market volatility forecasting. We study on the financial listed on the Ho Chi Minh
City Stock Exchange including four sub-industries such as insurance, real estate,
diversified finance and banks. Additionally, the four market-weighted indexes
(Vnindex, Hnxindex, VN30 index and UPCOM index) will also be employed. The
collected data, totally 45 common stocks, covered the period from the beginning of
2012 to 8th April 2016. In particular, ARCH, GARCH, GARCH-M, EGARCH,
EGARCH-M, GJRGARCH, GJRGARCH-M are employed to capture either time-
varying volatility or asymmetric effect. The hypothesis of risk-return tradeoff is
detected by GARCH-M models. In summary, both symmetric and asymmetric show
the inability of dealing with heteroscedasticity and autocorrelation in residuals on
whole financial industry. ARCH(2) and GARCH(1,1) are significantly found which
employed on the three market-weighted indexes (Vnindex, HNXindex and VN30
index). Last, the new contribution are that the samples of a whole financial industry
are investigated in this paper to detect whether time-series models are available.
Otherwise, the postestimations of heteroscedasticity and autocorrelation are carefully
focused to ascertain that there are not any disturbances in residuals.
Keywords: symmetry, asymmetry, ARCH, GARCH-type models, risk-return tradeoff,
heteroscedasticity.

1. Introduction
The study on the volatility of stock return is closely linked to the risk of financial
asset, meaning that higher volatility lead to large string of return, hence higher risk.
The volatility forecasting become an essential part of invest ment strategies and there
is two basic approaches to volatility comprising of constant variance and time-varying
volatility.
The constant variance can be capture by simplier model such as ARMA or
ARIMA model, first introduced by Box, Jenkins and Reinsel in 1994. Another problem
is the variance of error changing over time which could break the hypothesis of white-
noise residuals. The term “white-noise” indicates that the residual of return series must
be homoscedastic and unautocorrelated. We must differentiate with the term “white-
noise” in return series with finite mean and variance (Ruey S.Tsay, “Analysis of
Financial Time Series”, 2nd edition, p.31). Othewise the term of stationary is also
important showing that the mean of return series and covariance between current return
and its lagged value must be time-invariant. A well-known test of stationarity is
Dickey-Fuller (1979).
On the order hand, when the variance of error term is changing over time,
meaning heteroscedasticity, Engle (1982) proposed the Autoregressive Conditional
Heteroscedastic). The further models can be known as GARCH by Bollerslev (1986);
GARCH-in-mean by Engle, Lilien and Robins (1987); Exponential GARCH by Nelson
(1991); GJRGARCH by Glosten, Jaganathan and Runkle (1993); Threshold GARCH
might be the same as GJRGARCH. In general, according to Tim Bollerslev in 2007,
his “Glossary to ARCH(GARCH)”, GARCH-type models could be divided into two
group: the symmetric GARCH and the asymmetric GARCH. In particular, we use the
asymmetric GARCH to capture the leverage effect – one of residual behaviour. Another
essential test of ARCH effect in error term before using GARCH-family models was
Lagrange Multiplier test of Engle (1982).
2 | P a g e
Beginning with ARCH model first promoted by Engle (1982) to deal with time-
varying volatility, in ARCH model, the conditional variance of error is expressed as a
function of past squared error with the constraint of non-negative coefficients. But it
emerged some disadvantages that if these parameters are positve and the recent squared
residual are large, the current forecasted squared error will be large in magnitude in the
sense that its variance is large (Mohd. Aminul Islam, 2013). Other weakness is that
ARCH requires many parameters and maybe high order to capture the volatility while
Bollerslev (1986) remdedied this problem by Generalized ARCH model.
Furthermore, the volatility have some characteristics known as volatility clusters,
leverage effect. “Volatility clustering or volatility pooling shows that volatility may be
high for certain time periods and low for other periods, in short for the volatility
tendency in financial market to appear in bunches” (Chris Brooks, “Introductory
Econometrics for Finance”, 2nd edition, p.380). It could be detected through the
existence of significant correlation at extended lag length in correlogram and
corresponding Box-Ljung statistic (M.Tamilselvan 2016). And the term of leverage
effect indicated that volatility seems to react diffently to a big price increase or a big
price drop. This is the phenomenon of the tendency for volatility to rise more following
a large price fall than following a price rise of the same magnitude” (Chris Brooks,
“Introductory Econometrics for Finance”, 2nd edition, p.380). Basically, leverage
effect is known as the negative correlation between price movement and volatility
which first investigated by Black (1976) and the other evidence of Nelson (1991),
Gallant, Rossi and Tauchen (1992,1993).
To capture the asymmetry, a new class of GARCH was proposed such as
Exponential GARCH by Nelson (1991); GJRGARCH by Glosten, Jaganathan and
Runkle (1993); Threshold GARCH might be the same as GJRGARCH.
As an application on Vietnamese stock market, our main purposes are to
investigate and to model the stock return volatility. Likewise, the current paper will
detect whether there are any ARCH effect, volatility cluster or asymmetric effect in
3 | P a g e
stock return by both symmetric and asymmetric GARCH models (ARCH, GARCH,
EGARCH, GJRGARCH). The other useful hypothesis is that the risk-return tradeoff
is also encountered by GARCH-in-mean model.
Our paper was conducted with Financial industry on Hochiminh City Stock
Exchange (HOSE) including four sub-industries: insurance (4 tickers), real estate (30
tickers), diversified finance (6 tickers) and banks (5 tickers). Besides, we will also
investigate on market-weighted index comprising of Vnindex, HNXindex, VN30 index
and UPCOM index to detect whether GARCH models are available for market
volatility forecasting or not.
2. Research questions
The hypotheses to be tested for stock returns volatility are the following: 1)
whether there are any ARCH effect in return series using ARCH and GARCH, 2)
whether there are any asymmetric effect using EGARCH and GJRGARCH, 3) whether
the risk-return tradeoff using GARCHs-in-mean are statistically significant on
Vietnamese financial industry.
To the our best collection, it seem that few studies were officially studying on
Vietnam stock market. Moreover, there was no single one investigation of a wholly
financial industry from the year of 2012 till now (including 53 common stocks
classified by HoChiMinh Stock Exchange-HOSE). We first conduct this research on
only Financial stock marke before analyzing whole stock exchange.
Applying the model estimation progess from the below papers and the standard
proxy propose by Ruey S.Tsay (“Analysis of Financial Time Series”, 2005, the 2nd
edition, p.101-131), both symmetric and asymmetric will be utilized to take the
adequate volatility models. The stationarity Dickey-Fuller pretest and Lagrange
Multiplier (LM) test of heteroscedasticity will be executed, especially LM test included
in pre and post-estimation to ascertain that there are no remaining ARCH effect in error
term. The correlogram with ACF and PACF function are to detect the autocorrelation
in squared residuals and define the order of ARCH model.
4 | P a g e
Furthermore, the hypothesis of risk premiums in return series is to be detected
by GARCH-in-mean, EGARCH-in-mean and GJRGARCH-in-mean model while the
asymmetry will be captured by EGARCH and GJRGARCH. Model estimation will be
conducted on STATA 12 programme.
3. Literature review
There has been a large amount of literature on modelling stock market volatility,
as a proxy of risk, to define the most fittest for capturing many volatility characteristics.
However, we found no one studying on a whole industry and just employed two or
three samples.
To begin with Vietnames stock market, Tran Manh Tuyen conducted
investigation stock return volatility (using VNindex) covering the period 02/01/2009 –
16/10/2009 by both symmetric and asymmetric GARCH models (GARCH, GARCH-
In-Mean, EGARCH, GJRGARCH). VNindex is the value-weighted stock price index
of all common stocks traded on the Vietnam official stock exchange. The paper
indicated that higherrisk (proxied by the conditional variance) would not necessarily
lead to higher return (no risk-return tradeoff), meaning that GARCH-In-Mean model
was statistically insignificant. Moreover, there was no clue that the effect of shocks on
volatility was asymmetric, as well as insignificant EGARCH and TGARCH. But
essentially he did not show any test of stationary, autocorrelation and heteroscedasticity,
as well as the basic method of model order estimation. Last but not least, his study did
not retest the three characteristics of time-series after model estimation.The paper
named “Modeling volatility using GARCH models: Evidence from Vietnam) was
published on Economic Bulletin Vol.31, No.3, p.1935-1942 in 2011.
In the same year, 2011, Vo Xuan Vinh and Nguyen Thi Kim Ngan employed the
same ample (VNindex), from 01 March 2002 to 31 August 2010 and also had the same
conclusion about the symmetric volatility, meaning that TGARCH was insignificant.
But there was some differences that risk-return tradeoff hypothesis was statistically
significant with GARCH-M (1,1) model. It is doubtful that time periods of data of these
5 | P a g e
two paper was totally different. As the same deficiency as Tran Manh Tuyen, they did
not conduct the retest of autocorrelation or heteroscedasticity after model estimation.
Their paper was published on the Vietnamese Jounal of Development of Science and
Technology (14), Quarter 3-2011, page.5-20. Both papers conducting on Vietnam stock
market used the AIC and BIC criterion to selection among estimated models.
In 2011, Ahmed Alsheikh M.Ahmed and Suliman Zakaria utilized the symmetric
and asymmetric GARCH to capture the volatility of Khartoum Stock Exchange index
(KSE) from January 2006 to November 2010. Augmented Dickey-Fuller test (Dickey-
Fuller 1981) and Lagrange Multiplier proposed by Engle (1982) was used to test the
stationarity and heteroscedasticity before estimation. They directly use GARCH(1,1),
GARCH-M(1,1), EGARCH(1,1), TGARCH(1,1) and PGARCH(1,1), in spite of no
single explanation for order choosing. They had carefully retested the ARCH effect on
residuals by LM test but the serial correlation of error term was ignored. The result
showed that leverage effect and risk-return tradeoff were significant at 1% level.
Moreover, the total of Arch and Garch coefficient is approximately equal to one which
indicating highly persistent variance, namely the current level of volatility tended to be
positively correlated with its level during the immediately preceding periods. Their
research was disclosed on International Journal of Business and Social Science p.114-
128.
Another research of Suliman Zakaria with Peter Winker in 2012 displayed the
volatility model with symmetric or asymmetric studying on the Khartoum Stock
Exchange index (KSE) from Sudan and the Capital Market Authority index (CMA)
from Egypt over the periods from 2nd Jan 2006 to 30th November 2010. The Dickey-
Fuller stationary and Lagrange Multiplier (LM) of time-varying volatility test was
applied as a pre-estimation. Beside, LM test was also seen as the post-estimation to
ascertain that there was no remaining ARCH effects left in the residuals of the
estimated models. However, we discovered the same way of chossing model between
two papers of Suliman Zakaria in 2011 and 2012. The author directly using the simplest
form of GARCH-type models with the order (1,1) without any explainations. The
6 | P a g e
asymmetric (leverage) effect coefficient in both EGARCH(1,1) and TGARCH(1,1)
were respectively negatively and postively significant showing that negative shocks
imply a higher next period conditional variance than positive shocks.
Afees A.Salisu and Ismail O.Fasanya in 2012 also conducted three phases in
modeling symmetric and asymmetric volatility. To begin with the Lagrange Multilier
test of ARCH effects in squared residual, the author then proceeded to estimation and
using BIC and AIC to select the best fit one. GARCH with the order (1,1) was directly
used and ARCH model was not estimated based on the theoretical assumption that
GARCH with lower value of order provides a better fit than ARCH with high order.
The third phase was seen as postestimation using ARCH LM test to validate the
selected models as well as confirmed no remaining ARCH effect in residuals. Their
work was published on the International Journal of Energy Economics and Policy
(Vol.2, No.3, pp.167-183, ISSN: 2146-4553) which was named “Comparative
performance of volatility models for oil price”.
To capture the ARCH effect in residual and leverage effect, Sohail Chand and
coworkers had utilized the ARCH, GARCH-family models on the paper named
“Modeling and volatility analysis of share prices using ARCH and GARCH models”
which published on the World Apllied Sciences Journal 19 (1) in 2012 (p.77-82 and
ISSN: 1818-4952). The pre-estimation also began with ADF test of stationarity and
ARCH effect test. The author noted that ARCH effect was specified by correlogram of
squared residual when the ACF and PACF of squared errors show autocorrelation.
Likewise, this test was redone with the error obtained from the estimated models (with
the selection of AIC and BIC) to confirm well ARCH effect modelling.
To further research on the risk-return tradeoff, Heping Liu and Jing Shi in 2013
utilized various forms of GARCH-in-mean such as GJRGARCH-in-mean, EGARCH-
in-mean. Their paper was published on the Energy Economics 37 (p.152-166), namely
“Applying ARMA-GARCH approaches to forecasting short-term electricity prices”.
To conincide with other further researches, the author also employed the PACF of
7 | P a g e
residuals to disclose whether there were significant autocorrelations among the
residuals of estimated models or not.
The same as purpose of Heping Liu, Mohd. Aminul Islam in 2013 executed the
GARCH-in-mean models to test the risk-return hypothesis on Indonesian, Malaysian
and Singapore stock market with the sticker: JKSE, KLCI and STI respectively. The
data was collected from Jan 2007 to Dec 2012 which using daily log return. To embrace
the time-series progress, ADF test of stationarity and LM test of squared time-varying
error were executed. The author also used the GARCH with the simplest form with
order (1,1).Addiationally, the post-estimation with LM ARCH effect test and
autocorrelation function was preceded. Their result was disclosed on the Middle-East
Journal of Scientific Research 18 (7) (page.991-999 and ISSN: 1990-9233).
Likewise,another relevant conclusions of Ching Mun Lim and Siok Kun Sek in
2013 also contributes to our research for the countries in ASEAN, particularly Vietnam.
The authors had divided the data period (from 1990 to Dec 2010) into three phases: pre
crisis 1997, during crisis and post-crisis 1997, also using both symmetric and
asymmetric GARCH (Conventional GARCH, EGARCH and TGARCH) to modeling
the stock market volatility. In the normal condition (pre and post crisis), symmetric
GARCH seemed to be more preferred while asymmetric GARCH was highly
appreciated in the crisis period and post-crisis. They applied the conditional mean
equation of stock return which was constructed by the constant term plus the error
terms (rt=μ+εt). Ching Mun Lim also directly utilized the simplest form of GARCH
with the order (1,1). Additionally, there did not exist any test of stationarity, ARCH
effect and serial correlation in residuals for pre and post analysis. They just apllied
some error measures like mean squared error (MSE), root mean squared error (RMSE)
and mean absolute percentage error (MAPE) for ranking the GARCH performances.
Some doubts emerged whether there was any heterocsedastic residual to apply
GARCH models or not. Other problem arrived that no post-estimation was to ascertain
no remaining ARCH effect in residuals. Their result was published on the Procedia
Economics and Finance 5 (p.478-487).
8 | P a g e
Mohd. Aminul Islam in 2013 executed the study on Asian market (Malaysia,
Singapore, Japan and Hongkong) with the period from Jan 2007 to Dec 2012. The
author pointed out another research of Stock & Watson in 2012 (p.703) showing the
disadvantage of ARCH of the non-negative coeffients contraints since the variance
could not be negative. If these coefficients are positive and the recent squared error are
large, ARCH will predicts that current squared error will be large . As a consequence,
the simplest form GARCH (1,1) by Bollerslev 1986 was applied. Asymmetric GARCH
(EGARCH, TGARCH and PGARCH) was employed to tackle with leverage effect.
Otherwise, the risk-return relationship was again examined by GARCH-in-mean
(Engle, Lilien and Robin 1987). The writer also carefully conducted the ARCH LM
test test after model estimation. The result was pulished on the Australian Journal of
Basic and Applied Sciences 7(11) (p.294-303).
On Turkish stock market, R.Ilker Gokbulut and Mehmet Pekkaya researched on
BIST-100 index from 02/01/2002 to 04/02/2014 with 3027 daily observations of retuns.
Lagrange Multiplier test (1982) was preceding in pre and post estimation. Moreover,
AIC and BIC were used in model selection but writer also highlight that it was
inadequate with the still remaining ARCH effect of selected models if the AIC or BIC
value was smallest. This is an critical base for our research because both symmetric or
asymmetric GARCH can not capture the ARCH effect in spite of many remedial
measure like differencing and log normal functions. The paper of R.Ilker Gokbulut was
published on the International Journal of Economics and Finance (Vol.6, No.4 and
ISSN: 1916-971X) by Canadian Center of Science & Education.
Correlogram of autocorrelation to specify ACF and PACF of squared residuals
was also used by Yogendra Singh Rajavat and Amitabh Joshi in 2014. Their paper
named “Volatility in returns of BSE Small Cap Index using GARCH(1,1)” was
displayed on the Journal of Applied Management (Vol.II, Issue.I & ISSN: 2321-2535).
The other important test of ARCH disturbance in residuals was conducted. But the
paper seemed to be the same as the above literatures studying on only few samples.
9 | P a g e
As the same as the above papers, Trilochan Tripathy and Luis A. Gil-Alana in
2015 based on the error measures such as mean squared error (MSE), mean absolute
error (MAE) and mean absolute percent error to explain the forecast accuracy. Their
methodology included both symmetric and asymmetric GARCH (GARCH, EGARCH,
TGARCH) studying on S&P CNX Nifty of the National Stock Exchange in India (3rd
Aug 1992 to 21st Sep 2012). The test of Dickey & Fuller 1979 and Lagrange Multipiler
1982 were proposed in the pre-analysis but no single one in the post-analysis to check
out whether there was any remaining ARCH effect in residuals as standard progress.
Trilochan Tripathy et.al result was displayed on the Review of Development Finance
Journal 5 (p.91-97).
M.Tamiselvan and Shaik Mastan Vali applied GARCH, EGARCH and
TGARCH with the order (1,1) on Muscat stock market (MSM 30 Index, Financial
Index, Industrial Index, Service Index). Importantly, the coefficient of each model was
statistically significant at 1% level after estimation leading to the acceptable conclusion.
This result coincided with Tran Manh Tuyen 201. They only accepted the result if the
coefficients were all significant. Although the value of AIC and BIC was negative, they
also used as proxy to select among models.
Consequently, to our the best collection, it seems to have few studies on Vietnam
stock market in the period of 2012 till now. Moreover, most papers had been
investigated on two or three sample; there was no single one conducting on the whole
industry. Some research inadequately ignnored some post-estimation of
autocorrelation and ARCH effect in obtained residuals. The orther of GARCH model
was all used as the simplest form of (1,1). Additionally, Ruey S.Tsay gave futher
suggestion on specifying the order of GARCH model that only lower order GARCH
should be used in most application such as GARCH(1,1), GARCH(2,1) and
GARCH(1,2). As a standard proxy of error detect in pre or post-estimation, the
autocorrelation functions of squared residuals should be used to detect whether there
are any autocorrelations.
10 | P a g e
So our research will base on the instructive standard of Ruey S.Tsay in the book
of “Analysis of Financial Time Series and all references of above literature to conduct
the current investigation on Vietnamese Financial Industry, particularly. Both
symmetric and asymmetric GARCH models will be apllied to capture various
characteristics of time-series. The hypothesis of risk-return tradeoff also have been
tested by class of GARCH-in-mean models. Last, our main purpose is modelling the
stock return volatility by using univariate GARCH models.
4. Data description and methodology
4.1. Data and summary statistic
The descriptive summary: The time-series data used for modeling volatility in
this paper is the daily return of commons stock from the Financial Industry and listed
on Hochiminh Stock Exchange (HOSE). Data covers the periods from 3rd January 2012
to 8th April 2016.
The daily returns are calculated from daily closing stock prices collected from
cophieu68.com which are calculated as simple return (denoted rt): rt = [(Pt – Pt-1)/Pt-1].
Such a remedial measure, we will use the continously compounded return which are
the difference in logarithm of closing prices: rt = log(Pt/Pt-1) where Pt and Pt-1 are the
closing price at the current and previous day, respectively.
But we have to note that during the time-frame from the beginning of 2012 to 8th
April 2016, just getting the working day, common stocks will have their own different
number of trading days. Data comprises whole Financial industry with total 45
common stocks which is classified into 4 sub-industries by HOSE inclusing Insurance,
Real estate, Bank and Diversified financial (see table 1 & 2).
The four market-weighted index (Vnindex, HNXindex, VN30 index and
UPCOM index) cover the period also from the beginning of 2012 to 8th April 2016.
Vnindex and HNXindex are the market-weighted index of all common stocks which
are listed on the HOSE and HNX, respectively. VN30 index is also the market-
11 | P a g e
weighted index for 30 common stocks which have the largest capitalization, basing on
the oustanding shares, listed shares and charted capital. UPCOM is Unlisted Public
Company Market for which companies are under-conditional listed on HNX and
HOSE (see table 3).
During the collected periods, the mean return of the insurance group is about
0.11488% while the mean return of the real estate is approximately 0.0709%. And the
mean return of the diversifed financial industry is 0.1044% and 1.1909% for banks
industry (see table 4)
Besides, the kurtosis and the skewness are used to show the form of distribution
of return. The “kurtosis” describe the degree of the peak of the distribution when the
“skewness” describe the asymmetric from the normal distribution. For normal
distribution, the skewness is equal to zero and the kurtosis is equal to three (excess
kurtosis equals zero). If the skewness is different from zero showing the
nonsymmetrical distribution when one side of the distribution does not mirror the other.
Particularly, the positive skewness indicates long right tail distribution which specifies
frequent small negative outcomes; when the negative skewness signs the long left tail
distribution which indicates a greater chance of extremenly negative scenarios.
Additionally, if it is the higher positive excess kurtosis (leptokurtosis) showing a higher
peak with fat tail than the normal distribution. The lower negative excess kurtosis
(platykurtosis) showing a lower peak with thin tail than normal (Ruey S.Tsay, 2005,
“Analsysis of Financial Time Series”, p.7-16).
According to the above descriptive statistic (see table 4 & 5), it shows that most
return series have not normal distribution. For insurance group, all stocks return have
the over-three kurtosis and positive non-zero skewness while for real estate, half of
them have over-three kurtosis and half have the lower-three kurtosis. Moreover, real
estate shows that seven stocks return have negative non-zero skewness and the
remainers have the postive skewness. For diversified financial industry, all stocks
return haave positive non-zero skewness; four lower-3-kurtosis tickers and two over-
12 | P a g e
3-kurtosis tickers. About banking group, the result shows that all had over-three
kurtosis and positive non-zero skewness.
To the four market-weighted indexes, all have over-three kurtosis and negative
skewness. Negative skewness signs the long left tail distribution which indicates a
greater chance of extremenly negative scenarios. And the higher positive excess
kurtosis (leptokurtosis) showing a higher peak with fat tail than the normal distribution.
In brief, for descriptive summary, either the general financial industry or the four
market-weighted had non-normal distribution of return (see table 5)
Pretesting for Stationarity (see table 6.1 to 6.3): The ADF (Dickey-Fuller 1979)
will test the null hypothesis of nonstationary and the alternative hypothesis of
stationary. It will reject the null hypothesis if the absolute value of ADF test statistic
exceeds the absolute critical value at 1%, 5% or 10% significance level (Mohd.Aminul
Islam 2013; Nguyen Quang Dong 2012, p.524-528; Ruey S.Tsay 2005). The test as
following:
𝒓𝒕 = 𝒄𝒕 + 𝜷𝒓 + ∑ 𝜱𝒊∆𝒓𝒕−𝒊 + 𝒆𝒊
𝒑−𝟏
𝒊=𝟏
𝑯𝟎: 𝜷 = 𝟏
𝑯𝟏: 𝜷 < 𝟏
We denote the rt is the return series; while ct can be zero or constant, ∆𝑥𝑡−𝑖 is the
differced series of rt . The the ADF-test statistic is calculated as below:
𝑨𝑫𝑭 − 𝒕𝒆𝒔𝒕 = �̂� − 𝟏
𝒔𝒕𝒅(�̂�) ; �̂� 𝑖𝑠 𝑡ℎ𝑒 𝑙𝑒𝑎𝑠𝑡 𝑠𝑞𝑢𝑎𝑟𝑒𝑑 𝑒𝑠𝑡𝑖𝑚𝑎𝑡𝑒 𝑜𝑓 𝛽
As consequence, we can conculde that all sample result show the stationary (see table
6a, 6b & 6c). This is the fundamental for the following step of forecasting. The same
application in the others papers could be listed as Mohd.Aminul Islam 2013; Ahmed
Elsheikh M.Ahmed & Suliman Zakaria 2011; Rilker Gokbulut & Mehmet Pekkaya
2014; Dana Al.Najjar 2016; Sohail Chand, Shahid Kamal & Imran Ali 2012; Suliman
13 | P a g e
Zakaria & Peter Winker 2012; M.Tamilselvan & Shaik Mastan Vali 2016, Trilochan
Tripathy & Luis A.Gil-Alana 2015.
Pretesting for Heteroscedasticity (see table 7.1 to 7.3): The other
characteristics series are the heteroscedaticity which must be tested by Lagrange
Multiplier test (Engle, 1982). Additionally, one of the most important issue before
applying ARCH or GARCH models is to first examine the residuals for evidence of
heteroscedaticity by the Lagrange Multiplier Test proposed by Engle 1982 which
previously applied by Ahmed Alsheikh M.Ahmed & Suliman Zakaria 2011; Suliman
Zakaria & Peter Winker 2012; Rilker Gokbulut & Mehmet Pekkaya 2014; Sohail
Chand, Shahid Kamal & Imran Ali 2012; Afees A.Salisu & Ismail O.Fasanya 2012;
M.Tamilselvan & Shaik Mastan Vali 2016. We will obtain the residuals from the OLS
regression of mean equation then squared its as below:
𝒆𝒕𝟐 = 𝜶𝟎 + 𝜶𝟏𝒆𝒕−𝟏
𝟐 + ⋯ + 𝜶𝒒𝒆𝒕−𝒒𝟐 + 𝜺𝒕
The null hypothesis that there is no ARCH effect formulated as:
H0: α1 = α2 =…= αq = 0
H1: αi ≠ 0 (for at least one i= 1,2,…,q)
(Another form H1: α12+ α2
2+…+ αq2
>0)
If the value of LM test statistic (TR2) is greater than the critical value from the X2(q)
distibution or the coeffient of the lagged term is statistically significant, the null
hypothesis will be rejected. The same conclusion can be achieved of the F-version of
the test is considered. As consequence, we get all the value of LM test of all research
sample showing that there is ARCH effect in the squared error
Pretesting the autocorrelation in residual (see table 8.1 to 8.3): According to
intruction of Ruey S.Tsay in the book named “Analysis of Financial Time Series”
published by John Wiley and Sons 2005 (The 2nd edition, p.107-119), by
reinvestigating on the squared residual obtained by mean equation, we check out the
14 | P a g e
autocorrelation function (ACF – autocorrelation function or PACF – partial
autocorrelation function), if it is statically different from zero, the autocorrelation in
residuals is ascertained. As can be seen from the result of table 8.1-8.3, all sample show
that the error terms are autocorrelated
In summary, we find the evidence of stationary but existing the ARCH effect and
autocorraltion in residuals. It is also the principal condition to apply ARCH, GARCH
models.
The orders of ARCH and GARCH-type models will be discussed in the section
5.2 of methodology. It is the common way using ACF and PACF of squared errors to
specifying the order m of ARCH proposed by Ruey S.Tsay (2005, p.106-107). Tim
Bollerslev, in 1992, demonstrated that GARCH could be adapted by low orders such
as GARCH(1,1), GARCH(1,2) and GARCH(2,1) (T.Bollerslev, Ray Y.Chou 1992 and
Kroner, “ARCH modelling in finance: A reivew of the theory and empirical evidence”,
Journal of econometrics 52).

4.2. Methodology
Conditional heteroscedastic models are the basic econometrics tools used to
estimate and forecast asset return volatility depending on each time-series
characteristics. In the section we will review both symmetric (ARCH, GARCH) and
asymmetric GARCH-type models (EGARCH, GJRGARCH). Our aims are to study
some statistical methods and econommetric models avaible in the literature for
modelling the conditional heteroscedastic volatility model.
The univariate volatility models include the autoregressive conditional
heteroscedastic (ARCH) model of Engle (1982), the generalized ARCH (GARCH)
model of Bollerslev (1986), GARCH-in-mean of Engle, Lilien and Robin (1987), the
exponential GARCH (EGARCH) model of Nelson (1991), the GJRGARCH model of
Glosten, Jagannathan & Runkle (1993). These are models which will be displayed in
our current paper using the information selection criteria (AIC and BIC) to choose the
best fit. Following Ching Mun Lim & Siok Kun Sek (2013), we assume that the
conditional mean equation of stock return is defined as the constant term plus residuals
term: rt = μ + εt.
4.2.1. ARCH (m) – Engle 1982
Ruey S.Tsay in 2005 gave some instructions of model building with four phase:
specifying the mean equation and obtaining the residuals; conducting ARCH effect test
on the obtained residuals, the third with ARCH/GARCH model estimationand last step
of careful checking the fittest model and refining if necessary. The general model of
ARCH (m) process is as follow (Engle, 1982):
𝒓𝒕 = 𝝁 + 𝒖𝒕
𝒖𝒕 = 𝝈𝒕𝜺𝒕
𝝈𝒕𝟐 = 𝜱𝟎 + 𝜱𝟏𝒖𝒕−𝟏
𝟐 + ⋯ + 𝜱𝒎𝒖𝒕−𝒎𝟐
𝝈𝒕𝟐 = 𝜱𝟎 + ∑ 𝜱𝒊
𝒎
𝒊=𝟏
𝒖𝒕−𝒊𝟐
(𝜱𝟎 > 𝟎, 𝜱𝒊 ≥ 𝟎 𝒇𝒐𝒓 𝒊 > 𝟎)
Where Φ0 is constant, бt2 is the squared conditional variance of error term, ut-m
is the lagged value of error term. In general, бt2 is expressed as a function of past
squared errors. Another issue is that the unknown coefficients (Φ0, Φ1, Φ2,… Φm) must
26 | P a g e
be non-negative since the variance can not be negative meaning that ARCH assume
that positive and negative shocks have the same effects on volatility because it depends
on the squared of previous shocks. However the asymmetric literature proved that
return of financial asset responds differently to either positive or negative shocks (Ruey
S.Tay 2005; Nelson 1991; Glosten, Jagannathan and Runkle 1993 and Zakoian 1994;
Ding, Granger and Engle 1993).
If these coefficient are positive and the recent squared residual are large, ARCH
predicts that the current squared error will be large in magnitude in the sense that its
variance is large. Hence, ARCH models are likely to overpredict the volatility because
they respond slowly to large isolated shocks to return series (Ruey S.Tay 2005).
And if the ARCH effect is found to be statistically significant, we can use PACF
of ut2 (squared error term specified by correlogram in Stata programme) to intepret the
ARCH order (m). We have:
бt2 = Φ0 + Φ1u2
t-1 + Φ2 u2t-2 + … +Φm u2
t-m
Hence, u2t is an unbiased estimate of the squared variance of error term
(бt2).Otherwise, it is expected that u2
t is the linear regression of u2t-1, u2
t-2,…,u2t-m
as same as the autoregressive function AR(q) when the PACF is the useful tool for
determing the order of AR(q). For AR(q) model, the lagged (1) sample of PACF will
be close to zero. In brief, for an AR(q) series, the sample PACF cuts off at lag q and
the same version for ARCH(m) model based on PACF of squared errors (Ruey S.Tay
2005).
However, ARCH models are likely to overpredict the volatility since they
respond slowly to large shocks to the return. Additionally, ARCH(m) estimation will
often require a large number of parameters and higher order m to capture the volatility
process. As consequence, to remedy this problem, Bollerslev 1986 developed the
Generalized ARCH model (GARCH).
27 | P a g e
4.2.2. GARCH (m,s) - Bollerslev 1986
The standard GARCH (m,s) model espresses the variance at time t as following:
𝒓𝒕 = 𝝁 + 𝒖𝒕 𝒖𝒕 = 𝝈𝒕𝜺𝒕
𝝈𝒕𝟐 = 𝜱𝟎 + ∑ 𝜱𝒊
𝒎
𝒊=𝟏
𝒖𝒕−𝒊𝟐 + ∑ 𝜽𝒋
𝒔
𝒋=𝟏
𝝈𝒕−𝒋𝟐
[ 𝜱𝟎 > 𝟎, 𝜱𝒊 & 𝜽𝒋 ≥ 𝟎, ∑ (
𝒎𝒂𝒙(𝒎.𝒔)
𝒊=𝟏
𝜱𝒊 + 𝜽𝒋) < 𝟏 ]
The GARCH model allows the error variance (б2t) depending on either its own
past squared errors (u2t-m) or its own past values (б2
t-s) where m is the order of ARCH
terms and s is the order of GARCH term. GARCH also assumes that the variance is
non-negative. Large s order signs that shocks to the conditional variance take a long
time to die out meaning highly persistent volatility while large m order implies a
sizeable reaction of volatility to market movement. Hence, if 𝜱𝒊 + 𝜽𝒋 is close to untity,
the shock at t time will be persistent for many future periods. And one of the weakness
of GARCH model is the asumption of symmetry in volatility estimation.
We will apply GARCH(1,1), GARCH(1,2) and GARCH(2,1) with low order to
model the volatility and then use the information criteria to select the best fit (Ruey
S.Tsay 2005). Tim Bollerslev, in 1992, also specified that most low order GARCH such
as GARCH(1,1), GARCH(1,2) or GARCH(2,1) were employed (Tim Bollerslev, Ray
Y.Chou, Kenneth F.Kroner, “ARCH modeling in finance- A review of theory and
empirical evidence”, Journal of econometrics 52 (100), 1992, p.21-22).
4.2.3. GARCH-in-mean (m,s) – Engle, Lilien and Robin (1987)
Engle assume that the return of a security my depend on its volatility. To model
such a phenomenon, GARCH-in-mean was introduced with the following model:
𝒓𝒕 = 𝝁 + 𝒖𝒕 + 𝒄𝝈𝒕𝟐
𝒖𝒕 = 𝝈𝒕𝜺𝒕
𝝈𝒕𝟐 = 𝜱𝟎 + ∑ 𝜱𝒊
𝒎
𝒊=𝟏
𝒖𝒕−𝒊𝟐 + ∑ 𝜽𝒋
𝒔
𝒋=𝟏
𝝈𝒕−𝒋𝟐
28 | P a g e
The parameter c is called the risk premium parameter. The term of variance 𝝈𝒕𝟐
is added into the conditional mean equation intepreting the risk-return tradeoff
hypothesis. As an application, it can be listed such as Mohd.Aminul Islam 2013,
Suliman Zakaria & Peter Winkers 2012, Ahmed Elsheikh & Suliam Zakaria 2011.
If the parameter c is statistically positive, it will confirm the positive relationship
between return and volatility meaning high risk – high return. In order words, an
increase in return is caused by an increasse in the conditional variance (Enders, 2004,
“Applied Econometric Time Series, 2nd edition, Wiley Series in Probability and
Statistics). But either GARCH or GARCH-in-mean are also considered to be
symmetric model assuming that both positive and negative shocks of equal size
generate an equal effect on volatility.
Nonetheless, the negative shocks tend to have a larger impact on future volatility
than the positive one, namely asymmetric or leverage effect which has to be captured
by others asymmetric GARCH models (for instance: Exponential GARCH model
(EGARCH) of Nelson 1991 and GJRGARCH model of Glosten, Jagannathan and
Runkle 1993 as following sections).
4.2.4. Exponential GARCH (EGARCH) – Nelson 1991
To remedy some weakness of symmetric GARCH model, Nelson advanced the
following model as: EGARCH(m,s):
𝒓𝒕 = 𝝁 + 𝒖𝒕
𝒖𝒕 = 𝝈𝒕𝜺𝒕
𝒍𝒏(𝝈𝒕𝟐) = 𝜱𝟎 + ∑ 𝜱𝒊
𝒔
𝒊=𝟏
|𝒖𝒕−𝒊| + 𝜸𝒊𝒖𝒕−𝒊
𝝈𝒕−𝒊+ ∑ 𝜽𝒋
𝒎
𝒋=𝟏
𝒍𝒏 (𝝈𝒕−𝒋𝟐 )
The presence of parameter 𝜸𝒊 indicates an asymmetric effect of shocks on
volatility and the value of is statistically different from zero or negative signing the
asymmetry or the leverage effect (Ruey S.Tsay 2005; R.Ilker Gokbulut & Mehmet
Pekkaya 2014; Mohd.Aminul Islam 2013; M.Tamiselvan & Shaik Mastan Vali 2016;
Suliman Zakaria & Peter Winker 2012; Dana Al.Najjar 2016). Nelson used the logged
conditional variance to relax the positiveness contraint of GARCH model (Ruey S.Tsay
2005) and applied the absolute value of 𝒖𝒕−𝒊 to respond asymmetrically to positive
and negative lagged value of ut .
29 | P a g e
Hence, a positive ut-i contributes Φi(1+γi)/єt-i/ to the log volatility while a
negative ut-i specifies Φi(1-γi)/єt-i/ (where 𝜺𝒕−𝒊 =𝒖𝒕−𝒊
𝝈𝒕−𝒊). Since the negative shocks
tend to have larger impact than the positive shocks with the negative. Major papers
showed we can directly test the asymmetric effect on the estimated EGARCH model
by intepreting the statistically significant γi (≠0 or <0).
4.2.5. GJRGARCH – Glosten, Jagannathan & Runkle 1993
Here is the second common volatility model used to tackle with leverage effect,
namely GJRGARCH of Glosten 1993 as following:
𝝈𝒕𝟐 = 𝜱𝟎 + ∑(𝜱𝒊 + 𝜸𝒊𝑵𝒕−𝒊 )𝒖𝒕−𝒊
𝟐
𝒔
𝒊=𝟏
+ ∑ 𝜽𝒋
𝒎
𝒋=𝟏
𝝈𝒕−𝒋𝟐
Where Nt-i is the dummy variable used to differentiate the good or bad shocks:
𝑵𝒕−𝒊 = {𝟏 𝒊𝒇 𝒖𝒕−𝒊 < 𝟎𝟎 𝒊𝒇 𝒖𝒕−𝒊 ≥ 𝟎
GJR also has the constraint of non-negative coefficients (𝜱𝒊, 𝜸𝒊, 𝜽𝒋)which is
similar to GARCH model. A positive ut-i contributes Φiu2t-i to б2t volatility while a
negative ut-i contributes (Φi + 𝜸𝒊 )u2t-i to volatility б2t . Hence, GJR had assumed that
unexpected changes in the market will have different impact on the volatility of stock
return. Noting that a non-zero significant 𝜸𝒊 indicate the asymmetry and when 𝜸𝒊 > 𝟎
signs a leverage effect.
4.2.6. Remedial measures
Taking a differencing function when there is a serial correlation among error
terms and the correlation is expressed as following:
𝒖𝒕 = 𝒀𝒕 − 𝜱𝟎 − 𝜱𝟏𝒀𝒕−𝒊
(𝒘𝒉𝒆𝒓𝒆 𝒀𝒕 & 𝒀𝒕−𝒊 𝒊𝒔 𝒔𝒕𝒂𝒕𝒊𝒐𝒏𝒂𝒓𝒚)
When Yt and Yt-i is stationary, the error term ut is stationary saying that the
residual is the first order autocorrelation as: ∆𝑌𝑡 = 𝜱𝟏∆𝒀𝒕−𝒊 + 𝜺𝒕 (Nguyen Quang
Dong and Nguyen Thi Minh, 2012, “Econometrics”, National Economics University
Press, p.315).
30 | P a g e
Normally, the economic time series, such as stock return series would deal with
autocorrelation in residuals resulting the autorrelation function value often exceeds
zero (detected by ACF and PACF functions). Denoting the autocorrelation function
ACF(k) is ρk (Ruey S.Tsay, 2005, p.25-30):
𝝆𝒌 = 𝒄𝒐𝒓𝒓(𝒀𝒕, 𝒀𝒕−𝒌) = 𝜹𝒌
𝜹𝟎, 𝒌 = 𝟎, 𝟏, 𝟐, …
𝒘𝒉𝒆𝒓𝒆 𝜹𝒌 = 𝒄𝒐𝒗(𝒀𝒌, 𝒀𝒕−𝒌), 𝒌 = 𝟎, 𝟏, 𝟐, …
𝒘𝒉𝒆𝒏 𝒌 = 𝟎, 𝜹𝟎 = 𝒗𝒂𝒓(𝒀𝒕 )
(𝒔𝒆𝒆 𝒀𝒕 𝒂𝒔 𝒆𝒓𝒓𝒐𝒓 𝒕𝒆𝒓𝒎 𝒖𝒕)
4.2.7. Autocorrelation
Noting that serial correlation is related to the variance of parameter and if, after
model estimation, there is still correlated we should reject that models. Now we have
the equation of parameter variance, perhaps homoscedasticity is satisfied (Nguyen
Quang Dong, 2012):
𝒗𝒂𝒓(𝜷�̂�) = 𝝈𝟐
∑ 𝒙𝟐𝒕𝟐
𝒕
+ 𝟐 ∑ ∑ 𝒌𝒕𝒌𝒕+𝒔𝒄𝒐𝒗(𝒖𝒕, 𝒖𝒕+𝒔)
𝒏−𝒕
𝒔=𝟏
𝒏
𝒕=𝟏
Hence, when there is autocorrelated residuals, 𝟐 ∑ ∑ 𝒌𝒕𝒌𝒕+𝒔𝒄𝒐𝒗(𝒖𝒕, 𝒖𝒕+𝒔)𝒏−𝒕𝒔=𝟏
𝒏𝒕=𝟏 will
be different from zero causing that the variance of estimated parameter will be biased.
We could not continuously adapt the models and then the remedial measure of
diiferencing and loggeg function is to be used (as discussed in section 5.2.6).
4.2.8. Model information criteria
Akaike (1973) proposed AIC (Akaike information criteria) for model selection
(ARIMA, GARCHs) denoted as following:
𝑨𝑰𝑪(𝒍) = 𝐥𝐧 (𝝈𝒍𝟐)̂ +
𝟐𝒍
𝑻
𝒘𝒉𝒆𝒓𝒆 𝑻 𝒊𝒔 𝒔𝒂𝒎𝒑𝒍𝒆 𝒔𝒊𝒛𝒆 & 𝒍 𝒊𝒔 𝒕𝒐𝒕𝒂𝒍 𝒐𝒓𝒅𝒆𝒓
& 𝝈𝒍�̂� 𝒊𝒔 𝒕𝒉𝒆 𝒎𝒂𝒙𝒊𝒎𝒖𝒎 𝒍𝒊𝒌𝒆𝒍𝒊𝒉𝒐𝒐𝒅 𝒆𝒔𝒕𝒊𝒎𝒂𝒕𝒆 𝒐𝒇 𝝈𝒍
𝟐
𝝈𝒍𝟐 𝒊𝒔 𝒕𝒉𝒆 𝒄𝒐𝒏𝒅𝒊𝒕𝒊𝒐𝒏𝒂𝒍 𝒗𝒂𝒓𝒊𝒂𝒏𝒄𝒆 𝒐𝒇 𝒖𝒕
The first phrase of AIC measures the goodness of fit and the second phrase expressed
as the penalty function of the criterion. And Schwarz Bayesian (1978) introduced
another criteria (BIC):
31 | P a g e
𝑩𝑰𝑪(𝒍) = 𝐥𝐧 (𝝈𝒍𝟐)̂ +
𝒍 𝒍𝒏(𝑻)
𝑻
While the penalty for earch parameter is 2 for AIC criterion, BIC is penaltized with
ln(T). As application, it could be listed such as R.Ilker Cokbulut & Mehmet Pekkaya
2014; M.Tamilselvan & Shaik Mastan Vali 2016; Trilochan Tripathy & Luis A.Gil
Alana 2015; Sohail Chand, Shahid kamal & Imran Ali 2012; Afees A.Salisu & Ismail
O.Fasanya 2012; Dima Alberg, Haim Shalit & Rami Yosef 2008).
4.2.9. Error measures
(1) Root mean squared error (RMSE) is another favored measure:
𝑹𝑴𝑺𝑬 = √∑𝒆𝒊
𝟐
𝒏
𝒏
𝒊=𝟏
𝑹𝑴𝑺𝑬 = √𝟏
𝒏∑(𝒚𝒑𝒊 − 𝒚𝒂𝒊)
𝟐𝒏
𝒊=𝟏
(2) Mean absolute error (MAE):
𝑴𝑨𝑬 = 𝟏
𝒏∑|𝒚𝒑𝒊 − 𝒚𝒂𝒊|
𝒏
𝒊=𝟏
(3) Mean absolute percent error (MAPE):
𝑴𝑨𝑷𝑬 = 𝟏
𝒏∑ |
𝒚𝒑𝒊 − 𝒚𝒂𝒊
𝒚𝒂𝒊|
𝒏
𝒊=𝟏
(4) Theil’s inequality coefficient (TIC):
𝑻𝑰𝑪 =
√𝟏𝒏
∑ (𝒚𝒑𝒊 − 𝒚𝒂𝒊)𝟐𝒏𝒊=𝟏
√𝟏𝒏
∑ (𝒚𝒑𝒊)𝟐𝒏𝒊=𝟏 + √𝟏
𝒏∑ (𝒚𝒂𝒊)𝟐𝒏
𝒊=𝟏
The measure MAE and RMSE are depend on the scale of variable and just be employed
in comparing the forecast of the same variables across different models. And MAE is
generally affected by larger errors. Then MAPE and TIC is the alternative tool to
compare model forecast accuracy. MAPE and TIC are both insentitive to the scale of
variables. The smaller the all above ratios , the better the estimated model. Other note
32 | P a g e
that TIC is ranges between zero and one with the value of TIC converging to zero
showing the better. Heping Liu & Jing Shi 2013, Ching Mun Lim & Siok Kun Sek
2013 and Dima Alberg 2008 had applied these measure into their papers to compare
among defined symmetric and asymmetric volatility models. Hence, we just utilize the
MAPE and TIC to compare the model’s accuracy.
4.2.10. The l-step ahead forecast
The last phases came for forecasting with the l-step ahead forecast for ARCH(m) at the
forecast origin h (Ruey S.Tsay, 2005). The 1-step ahead forecast is denoted б2h+1:
𝝈𝒉𝟐(𝟏) = ɸ𝟎 + ɸ𝟏𝒖𝒉
𝟐 + ⋯ + ɸ𝒎𝒖𝒉+𝟏−𝒎𝟐
The 2-step ahead forecast б2h+2 :
𝝈𝒉𝟐(𝟐) = ɸ𝟎 + ɸ𝟏𝝈𝒉
𝟐(𝟏) + ɸ𝟐𝒖𝒉𝟐 + ⋯ + ɸ𝒎𝒖𝒉+𝟐−𝒎
𝟐
We have the general equation for l-step forecast as following:
𝝈𝒉𝟐(𝒍) = ɸ𝟎 + ∑ ɸ𝒊
𝒎
𝒊=𝟏
𝝈𝒉𝟐(𝒍 − 𝒊)
𝒘𝒉𝒆𝒓𝒆 𝝈𝒉𝟐(𝒍 − 𝒊) = 𝒖𝒉+𝒍−𝒊
𝟐 𝒘𝒊𝒕𝒉 (𝒍 − 𝒊 < 𝟎)
But we have to note that the weakness of ARCH models are likely to overpredict the
volatility because they respond slowly to large shock to return. GARCH also has others
shortcoming that the large past squared value of residual and variance give an increase
to the current variance. GARCH’s phenomenon showed that the large shock in the past
tended to be followed by another large shock (as volatility clustering). Additionally,
the 1-step ahead forecast of GARCH(1,1) at the forecast origin h, as following:
𝝈𝒉+𝟏𝟐 = ɸ𝟎 + ɸ𝟏𝒖𝒉
𝟐 + 𝜷𝟏𝝈𝒉𝟐
(𝑤ℎ𝑒𝑟𝑒 𝑢ℎ & 𝜎ℎ2 𝑎𝑟𝑒 𝑘𝑛𝑜𝑤𝑛 𝑎𝑡 𝑡ℎ𝑒 𝑡𝑖𝑚𝑒 ℎ)
In general, for l-step ahead forecast in GARCH model, we have:
𝝈𝒉𝟐(𝒍) = ɸ𝟎 + (ɸ𝟏 + 𝜷𝟏)𝝈𝒉
𝟐(𝒍 − 𝟏), 𝒍 > 𝟏
33 | P a g e
5. EMPIRICAL RESULTS AND DISCUSSIONS
` To again introduce, data mangement is performed by Stata 12 programme. After
we pre-test the return seires in the section 5.1, the result displays that there was ARCH
effect in the residual but stationary.
The following sections are divided into two sections: section 5.1-the model
estimation for the financial industry, section 5.2-the model estimation for the four
market-weighted indexes.
The model we applied are ARCH(m), GARCH(m,s), GARCH-M(m,s)
EGARCH(m,s), EGARCH-M(m,s), GJRGARCH(m,s) and GJRGARCH-M(m,s).
For both section 5.1 and 5.2, we estimate the proper model and the value of BIC
and AIC will be generated after each model estimation in order to compare which is
more available. In our paper, we only disclose the result after using the AIC and BIC
to filter (see appendix 1)
Each section will also include the first post-estimation of ARCH effect and
serial correlation using again Lagrange-Multilier and ACF, respectively basing the
preceeding filter result.
If there is still remaning the ARCH effect or autocorrelation in residuals meaning
useless inadequate model, reject it. To remedy, we have to refine the model by
differencing and natural logarithic functions. We, first, also have to generate the ARCH
effect test. Then redefining the model on remedied data (see appendix 2)
Last, the second post-estimation of ARCH effect and autocorrealtion must be
executed (see appendix 3). If the post-estimated model, again, can not capture the
ARCH effect or serial correlation, reject it. Last, the remainers which can totally
capture the ARCH effect and serial correlation are used to forecast. The error measures
will be generated to choose which is the best accuracy one.
34 | P a g e
5.1. The model estimation result of the financial industry
5.1.1.The model selection
After executing both symmetric and asymmetric GARCH, the two information
criterions (AIC & BIC) were used to select the model and the detailed model
parameters will be attached on the appendix 1 (Appendix 1: The model parameters
result of financial industry)
ARCH model estimation (see table 9): For insurance industry including BIC,
PGI, BMI and BVH, the first two tickers followed ARCH(1) while the last two follow
ARCH(3) and no one was available for ARCH(4) and ARCH(5).
For real estate including 30 common stocks, the majority were available for
lower order ARCH models (ARCH(1) and ARCH(2)). There were five tickers followed
ARCH(3) which were BCI, CLG, FLC, NTL, TDH and the last one ITC followed
ARCH(4). In short, most tickers in real estate followed the ARCH(1) & ARCH(2).
For diversified finance, three tickers followed ARCH(3) which were HCM, OGC,
SSI. The ARCH(1) was fitted by BSI and AGR was used for ARCH(2). Especially,
only one tickers followed ARCH(4) which was PTB.
Beside, banking tickers seemed to be available for high order ARCH, at least 2.
We had CTG and MBB following much high order ARCH(4) and ARCH(5).
Now we have to focus the principle of the ARCH’s weakness. ARCH model
often require many parameter to adequately describe the volatility process of return
series so that we other proper model was GARCH-family models. Our results seemed
to correspond with the previous papers, GARCH(1,1) was more available for most
tickers
GARCH-family models estimation (see table 10.1 – 10.2): The insurance
industry was totally captured by both symmetric and asymmetric GARCH(1,1). For
real estate, 16 tickers also followed the simplest model of GARCH and the others 14
tickers followed higher order. While most tickers in diversified finance and banking
group follow the lowest order GARCHs
Noting that, we can not applied these models if the post-estimation of
heteroscedasticity and autocorrelation test were not executed. And if the post results
indicated that they could not capture the problem, we have to refine the model by
35 | P a g e
differencing and logging functions.
5.1.2. The first postestimation of heteroscedasticity and autocorrelation
The test for conditional heteroscedasticity is the Lagrange multiplier (LM) test
proposed by Engle 1982. The test is equivalent to the F statistic for testing αi =0
(i=1,…,m) in this auxiliary linear regression (Ruey S.Tsay, “Analysis of financial time
series”, Second edition, page. 101-102). To retest whether there are any remaining
Arch Effect in the residuals, the LM test was also applied in R.Ilker Gokbulut &
Mehmet Pekkaya, 2014, “Estimating and forecasting volatility of financial markets
using Asymmetric Garch models: An application on Turkish financial markets”,
International Journal of Economics & Finance, vol.6, no.4, ISSN 1916-971X. Afees
A.Salisu & Ismail O.Fasanya in 2012 also conducted the ARCH LM test on order to
ascertain of the chosen models had captured these effects; the same as Kolade Sunday
Adesina.
Here below is the auxiliary regression of squared residual and its lagged value
on m lags which haved been previously selected using AIC and BIC information
criterion:
And the null hypothesis H0: α1=....=αm=0. First we have to obtain the residual and
square them. Then, we define the test statistic (TR2) and compare the p-value from this
statistic to the desired test level (α) and reject the null hypothesis if the p-value is
smaller (Ruey S.Tsay,” Analysis of financial time-series, Second edition, John Wiley
& Sons Publication, p.101-102).
Additionally, the autocorrelation of residuals have also been retested to confirm
whether there are any serial correlation by autocorrelation function of the obtained
squared residual from previous model selection phase (Ruey S.Tsay, “Analysis of
financial time-series”, Second edition, page. 116-120). The empirical test of
autocorrelation by ACF was also proposed by Walter Enders, “Applied Econometric
Time-Series”, John Wiley & Sons Publication, page.147-153.
If the both tests of heteroscedasticity and serial correlation in residuals show that
there is still remaining the ARCH effect or autocorrelation, the remedial measure

including the log normal of return and differencing function must be applied (Nguyen
Quang Dong, “Econometrics”, 2012, page.295-317).
In term of application of autocorrelation retest, Haping Liu and Jing Shi in 2013
also employed the partial autocorrelation function (PACF) of residual to determine that
there did not exist significant autocorrelation among the residual gathered after each
model estimation. Their paper, in 2013, studied “Applying Arma-Garch approaches to
forecasting short-term electricity prices” which was published on the Journal of Energy
Economics p.152-166.
The result was unexpected. All of the four sub-industies was heteroscedastic
and serial corralted even if we applied both symmetric and asymmetric volatility
models (See table 11.1 to table 13.3). Table 11.1 to table 11.17 will present the first
post-test of ARCH effect and autocorrelation for insurance and real estate. Table 12.1
to table 12.3 will display the pre-test result of the diversified finance industry and table
13.1 to table 13.3 will display the result of banking industry.
There still existed a very high value of Chi squared distribution test and a zero
P-value much less than α (1%, 5% and 10%). As consequence, the null hypothesis of
no ARCH effect must be rejected. Other wise the test of autocorrelation also was
unsatisfactory as same as the ARCH effect result with a non-zero ACF and PACF and
p-value of zero much less than the α (1%, 5% or 10%).
This result was not satisfactory. Infact, this is an very important post-estimation
we have to execute. However, some researches ignored this phase such as Tran Manh
Tuyen, 2011, “Model volatility using GARCH models: Evidence from Vietnam”,
Economics Bulletin, Vol.31, no.3, pp.1935-1942. The lack of this postestimation was
also seen at the paper of Dana Al.Najjar, 2016 (Asian Journal of Finance & Accounting,
ISSN: 1946-052X, Vol8, No.1, p.152-167). The same inadequacy was signed at the
study of Shing Mun Lim & Siok Kun Sek, 2013 (Procedia Economics and Finance 5,
p.478-487) and of Dima Alberg, Haim Shalit and Rami Yosef, 2008 (Applied Financial
Economics 18, p.1201-1208).

5.1.3. The remedial measure and model reformation
As the consequence of the first post-estimation, both symmetric and asymmetric
GARCH model could not capture the ARCH effect and autocorrelation. We refined the
model as taking the logarithm and differencing to remedy the issue. First, we also have
to test the ARCH effect on the new database (see the table 14.1 to 14.2).
The result showed that there are ARCH effect in the residual of differenced
logged return series. Hence, we will again reestimate basing on the result of the first
selection by AIC and BIC. Noting that after each new model estimation, we have to
obtain the residual to make the second postestimation to ascertain whether there are
any remaining ARCH effect or serial correlation in error terms.
And importanly, for this step we must focus on the paper’s research question
are to detect: 1) whether there are any ARCH effect in return series, 2) whether there
is asymmetry or leverage effect, meaning that volatility reacts differently to a big
increase or a big drop, 3) if the hypothesis of risk-return tradeoff is statistically
significant and 4) if Garch-family models could capture these all effect on Vietnam
financial section.

To check the appendix 2, we will display all the model result after refining
(Appendix 2: The refined models for financial industry).
ARCH model reformation result (see appendix 2.1 & 2.4): As the result after
refining, ARCH(1) was statistically significant for most of the insurance (4 tickers) and
real estate (27 tickers) while the three remainers (PDR, SJS, TIX) of real estate
followed higher order with ARCH(2) and ARCH(3). For the diversified finance and
banking industry, most were statistically captured by ARCH(1), except MBB for
ARCH(4). But the second post-test, again, showing that there was still remaining
ARCH effect and autocorrelation in residuals. Consequently, we concluded that ARCH
models were not adequate for all financial industry.
66 | P a g e
GARCH model reformation result (see apendix 2.1 & 2.4): For insurance and
real estate groups, the simplest GARCH (1,1) model was proved to be significantly
available for 22 tickers of real estate and all 4 tickers of insurance. Diversified finance
& banking also followed GARCH(1,1)
GARCH(1,2) statisfied 5 tickers of real eatate (including D2D, DXG, FDC, ITC,
PDR) and only three remainers were statistically insignificant (ASM, NVT, CIG).
Additionally, the sum of Arch term and Garch term (Φ+ θ ) for all models were less
than one showing concluding that there were no the persistent volatility.
EGARCH and GJRGARCH models reformation result (see appendix 2.2 &
2.5): The order important hypothesis of leverage effect or asymmetry that volatility
reacts differently to a big increase or a big drop was detected by EGARCH and
GJRGARCH.
The result indicated that the parameter γ was statiscally insignificant in majority
showing that both insurance & real estate stock return volatility seemed to react in the
same size on both negative or positive shocks. In particular, 27 tickers were not
available for EGARCH(1,1) and only seven remainers was weakly significant at 10%
level (as CCL, CLG, DTA, NTl, PTL, TDH, DRH). Beside, GJRGARCH (1,1) were
also not applicable for 25 tickers in majority (in constrast, BCI, CCL, CLG, DTA, LHG,
NBB, PTL, VPH, PDR).
For diversified finance and banking industry, majority was not significant with
the asymmetry parameter γ. The exception were BSI, SSI, EIB, AGR, and MBB.
Particularly, only three ticker followed asymmetric EGARCH (BSI, SSI, EIB) and
GJRGARCH( AGR, BSI, MBB).
GARCH-M model reformation result (see appendix 2.3 & 2.6): The third
hypothesis of risk-return trade-off was captured by GARCH-M, EGARCH-M and
GJRGARCH-M. The result showed that high volatilty (high risk) were not necessarily
lead to high return. As result, GARCH-M (1,1) were not available for 26 tickers (3
tickers of insurance and 23 of real estate).Additionally, EGARCH-M(1,1) was not
statistically significant for 33 tickers (4 of insurance and 29 of real estate). And 26
tickers were not available for for GJRGARCH-M(1,1). It could be concluded that there
was inefficient risk-return tradeoff for insurance and real estate on HOSE.
67 | P a g e
Otherwise, there also seemed that high volatility did not neccesarily lead to high
return in the diversified finance and banking industry (see appendix 2.6).
The second post-estimation: The post-test showed the unstatisfactory result that
both symmetric and asymmetric GARCH models could not capture the
heteroscedaticity and autocorrelation in error terms (see appendix 3.1 and 3.2). Since
the Lagrange Multiplier specified that both symmetric and asymmetric GARCH could
not capture the leverage effect, we rejected these models. In brief, we could use
GARCH-family models to describe the volatility of financial industry in HOSE.
Futhermore, we continued others same test on the four market-weighted indexes
such as Vnindex, HNXindex, VN30 index and UPCOM index. Finally, we found it
statically significant for Vnindex, HNXindex and VN30 index (see section 5.2.2).
5.2. The market-weighted indexes volatility modelling
The symmetric and asymmetric GARCH were applied to detect whether:
1/GARCH models could capture the market volatility, 2/There are any risk-return
tradeoff, 3/There are any leverage effect in market volatility, 4/ Market volatility could
be forecasted.
We also conduct the same progress as financial industry: first is the pre-test of
stationarity, heteroscedasticity and autocorrelation; second is the model estimation,
third is the post-estimation. The phase of remedial meaure to refining models will be
executed if the first post-estimation was not satisfied.
5.2.1. Pre-estimation
The Dickey-Fuller test shows that the null hypothesis of non-stationarity was
rejected. The absolute of test statistic was larger than the critical value and the p-value
was less than the significance level (1%, 5% and 10%) (see table 15.1)
The Lagrange Multiplier test of heteroscedasticity indicates that there are ARCH
effect in all four residuals while the ACF and PACF showed the autocorrelation in
residual (see table 15.2).
After pre-testing, we adapte symmetric and asymmetric GARCH to model
matket volatility as discussed on table 16.1 to table 16.3. Comparing to the post-
estimation, ARCH(2) and GARCH(1,1) could capture the heteroscedasticity in the
residual due to the result of LM test and Autocorrelation (see table 17.1 to table 17.2) .
68 | P a g e
ARCH(2) and GARCH(1) will be used to forecast the volatility of Vnindex, HNXindex
and VN30 index for the following 14 days from 11/04/2016 to 29/04/2016.

5.2.2. Model estimation of the four market-weighted indexes:
As previous applications, both symmetric and asymmetric GARCH-type models
were utilized to describe the market volatility. Phillip Hans Franses & Dick Van Dijk,
in 1996, applied GJRGARCH (1992) to capture the cross-country market-weighted
indexes such as DAX (Germany), EOE (The Netherlands), MAD (Spain), MIL (Italy)
and VEC (Sweden) covering the historical data of 9 years (Phillip & Dick, 1996).
Another paper, in 2013, by Mohd. Aminul Islam, that symmetric GARCH and
GARCH-M were employed to model the volatility of the three market-weighted
indexes including KLCI (Kuala Lumpur Composite Index), JKSE (Jakarta Stock
Exchange Composite Index) and STI (Straits Time Index). Author directly used the
simplest GARCH(1,1) and GARCH-M(1,1) spanning the period from Jan 2007 to Dec
2012. Paper was found that risk-return tradeoff was statistically significant only for
Indonesian market, except Malaysia and Singapore. (Mohd. Aminul Islam, 2013,
Middle-east journal of scientific research, ISSN:1990-9233, p.991-999).
Suliman Zakaria and Peter Winker, in 2012, applied both symmetric and
asymmetric GARCH to capture the two market-weighted indexes such as KSE
(Khartoum Stock Exchange, from Sudan) and CASE ( Cairo and Alexandria Stock
Exchange, from Egypt). In particular, GARCH(1,1), GARCH-M(1,1), EGARCH(1,1)
and TGARCH(1,1) were all displayed to cover the period of 2nd Jan 2006 to 30th Nov
2010. The positive risk premium was significantly found. (Suliman Zakaria and Peter
Winker, 2012, International journal of economics and finance,ISSN: 1916-971X,
p.161-176)
The orther older paper in 1993, published on The Journal of Finance by Glosten,
Jagannathan and Runkle, disclosed the GARCH-M to model the Center for Research
in Security Price (CRSP) value-weighted stock index during the period April 1951 to
December 1989. The negative relation between return and volatility was detected.
In our papers, ARCH and univariate GARCH models will be employed on the
volatility descriptions with the sample including the four Vietnamese market-weighted
indexes (VNindex, HNXindex, VN30 index and UPCOM index) (see table 16.1 to
16.3).
70 | P a g e
ARCH model estimation result (see table 16.1): ARCH(2) was adequately
defined as the proper model after using the information criterions, except for UPCOM
index. We will display the ARCH parameter for the lag 1 and 2 preparing for the step
of forecasting. Noting that all ARCH parameters were statistically significant and non-
zero at 1% level.
GARCH model estmation result (see table 16.1): We found that the total of
ARCH and GARCH parameter persistent volatility (Φ+ θ) for HNX and UPCOM
nearly converge to 1. It means that the past volatility would lead to the future volatility.
GARCH(1,1) was found to be statistically significant for all indexes
EGARCH and GJRGARCH model estimation result (see table 16.2): The
asymmetric parameter was significant for Vnindex and UPCOM index at 1%
significance level. The EGARCH(1,1) was 5% significant for HNXindex but
insignificant for VN30 index. And GJRGARCH(1,1) was 10% significant for VN30
but insignificant for HNXindex. In short, it might have the leverage effect on the
volatility for Vietnam stock market.
GARCH-M, EGARCH-M and GJRGARCH-M model estimation result (see
table 16.3): We found no significant risk-return tradeoff for the four market-weighted
indexes meaning that the higher volatility (higher risk) will not be necessarily
correspondent with higher return.
In brief, ARCH(2) and GARCHs with the lowest order (1,1) was available and
then, these defined models must suffer the post-testing of heteroscedasticity and
autocorrelation to define which could be used to forecast the market volatility.
5.2.3. The post estimation
As can be seen the result from table 17.1 to table 17.2, ARCH(2) and
GARCH(1,1) could capture the time-varying volatility of the market indexes such as
Vnindex, HNXindex and VN30 index but for UPCOM index.
The Lagrange Multiplier test showed the p-value exceeding the significance α
meaning that we could accept the null hypothesis of time-unvariant residual. And the
p-value of Q statistic for autocorrelation was also less then the significance α. The null
hypothesis of no serial correlation was accepted. ARCH(2) and GARCH(1,1) could be
used to forecast the market volatility.

5.2.4. Volatility forecasting and error measure
We applied ARCH(2) and GARCH(1,1) to forecast the volatility of Vnindex,
HNXindex and VN30 index (see table 18.1 to table 18.6). And the 1-step ahead
forecasting will be again employed to make forecasting for the following 14 days from
08/04/2016 to 29/04/2016. The day of 08/04/2016 will be the origin time. Additionally,
we need to remember ARCH and GARCH which were used in short-term forecasting.
Otherwise, we will compare the result of 14 days forecasting and 1 day
forecasting to test the accuracy of the Vietnam stock market by the mean absolute
percenatge error (MAPE) and Theil’s inequality coefficient (TIC) (see table 19).
For Vnindex, ARCH(2) forecasting for 1 day had the lower value of MAPE and
TIC than GARCH(1,1). And, for 14 days, ARCH(2) also provide more satisfactory
result (noting that TIC is ranged from 0 to 1, the closer zero the more accurate). The
poorest was 14-days forecasting by GARCH(1,1).
For HNXindex, if we predict in 1 day, GARCH(1,1) would be more available
and the same as 14-days forecasting.
However, VN30 index was much more complicated. For 14-days prediction,
GARCH(1,1) would be the better while for 1-day, ARCH(2) could be more successful.
In brief, the ARCH and GARCH models would be more available for short-term
forecasting, especially for 1-day. However, on Vietnamese stock market, it is still not
ready for intraday trading (T+0). For 14-days ahead prediction, the result was also
accurate. In 2017, we expect that the disclipine for intraday trading would be valid and
our research would be more applicable.
6. Conclusion and further researches
We find that both symmetric and asymmetric GARCH models are not available
for Financial industry listed on HOSE. However, the application of short-term
volatility forecasting on the four Vietnamese market-weighted indexes are statistically
significant. ARCH(2) and GARCH(1,1) are found to be significant. The forecast
accuracy would be dependent on the different length of prediction for each marker
index.
The hypothesis of risk-return tradeoff is insignificantly found showing that higher
risk (higher volatility) does not neccerarily lead to higher return. And the term of
77 | P a g e
leverage effect is statistically insignificant signing by the parameter γ of EGARCH and
GJRGARCH models. Both asymmetric models could not capture the time-varying
volatility and autocorrelation due to LM test and autocorrelation function.
Importantly, the progress of model building can not be ignored the post-
estimation of heteroscedasticity and autocorrelation. Before deciding to use the
estimated model to forecast, you must ascertain that there are no remaining ARCH
effect and serial correlation in residual, if not, reject it. But we found some papers (see
the literature review) which did not execute this post-step, the result could be less
reliable and biased.
Despite our unexpected results for financial industry, as we recommended in the
introduction section that there are very few papers conducting on Vietnamese stock
market. Moreover, there is no single one investigating for a whole industry to figure
out the proper volatility models. Our current papers are conducted on a whole financial
industry listed on HOSE which include four sub-industries (insurance, real estate,
diversified finance and banks). In addition, we conduct on the four market-weighted
indexes to describe the market volatility.
Limitation and further researches
First, our limitation is the time contraint so that we can not investigate on all
industries of both Hanoi Stock Exchange and Hochiminh Stock Exchanged. If it can
be tested all industries, we will found the proper time-series models for each industry.
Moreover, some previous researches shows that others variables, for instance:
daily trading volume, daily crude oil prices, could impact the stock return volatility.
Anh the hypothesis of “Friday effect” also can be detected by ARCH and GARCH
models.
For our further researched, following the result of significant volatility modelling
for market-weighted index, as well as market risk modelling, we would carefully
consider others new variable such as crude oil, daily trading volume which can be
added to find the relationship with volatility. Moreover, we will conduct both
symmetric and asymmetric for all industries in Vietnam to detect the proper model for
each group.
