Life Cycle Fundsu In recent years, “life cycle” funds have become an important
financial vehicle for retail investors – as of May 2006 we estimate that there is at least $100 Billion invested in Lifecycle funds.
u Lifecycle funds are designed to address the needs of individuals who are planning on retiring at a particular future date
u During the course of the life cycle, the investment policies of the fund vary from:– Emphasizing capital accumulation during the early years– Emphasizing preservation of capital, income and liquidity
approaching and in retirement.u These funds save the individual investor from having to
periodically reformulate their asset allocation policies as theyapproach retirement.

Life Cycle Funds: The Theory
u Gerd Infanger and George Dantzig developed many of the underlying ideas behind a dynamic approach to life-cycle investing: “Multi-stage Stochastic Linear Programs for Portfolio Optimization,” Annals of Operations Research, December 1993
u Jarrod Wilcox introduced the idea of how an investors’ balance sheet (assets, liabilities and discretionary wealth) affects their optimum portfolio: – “Harry Markowitz and the Discretionary Wealth Hypothesis,”
Journal of Portfolio Management, Spring 2003– diBartolomeo, Horvitz and Wilcox, “Life-Cycle Investing,”
Chapter 3: Investment Management for Taxable Investors, CFA Institute, 2006

Discretionary Wealth = Assets - Liabilities
![Page 8: Using Lifecycle Funds in a Suitable and Optimal …6 Life Cycle Funds: The Theory uGerd Infanger and George Dantzig developed many of the underlying ideas behind a dynamic approach](https://reader033.vdocument.in/reader033/viewer/2022041620/5e3e5bd78dde5e583a70c736/html5/thumbnails/8.jpg)

Life-Cycle Investing
uUtility is the median expected discretionary wealth.– Leverage = Assets / Liabilities– Maximize discretionary wealth.– If you include human capital as part of
financial assets, discretionary wealth usually decreases as an investor approaches retirement.

Financial Leverage and the Life Cycle
u Utility = LE[r] – L2σ2/2 + SL3σ3/3 – KL4σ4/4– L = Leverage = Assets / Liabilities– s 2 = Risk (variance)– S = skew– K = kurtosis. Normal K = 3. Fat tails K > 3.
v For a “typical” diversified portfolio, 4<K<5 over the last 15 years
v 4<K<5 is similar to a t-distribution with 7-10 degrees of freedom.
![Page 10: Using Lifecycle Funds in a Suitable and Optimal …6 Life Cycle Funds: The Theory uGerd Infanger and George Dantzig developed many of the underlying ideas behind a dynamic approach](https://reader033.vdocument.in/reader033/viewer/2022041620/5e3e5bd78dde5e583a70c736/html5/thumbnails/10.jpg)

Financial Leverage and the Life Cycle
u Utility = LE[r] – L2σ2/2 + SL3σ3/3 – KL4σ4/4– Ignoring higher moments and dividing both sides by L:
Utility = E[r] – Lσ2/2Utility = E[r] - λσ2
λ = L / 2u If leverage is less than 1.5, we have a high net worth investor.
– Life cycle funds are not appropriate because the high net worth investor has a multi-generation or charitable horizon.
u If leverage (< 3) and volatility (< 9%/year) are reasonably lowfor volatility), then ignoring higher moments is probably OK.
u Higher moments are a important if volatility is too high for theleverage.– In other words, risky portfolios with negative skew or excess
kurtosis are even riskier (with regard to asset/liability shortfall) than they appear in a world where only mean and variance count.

What We Are Going to Do1. We are going to develop 40 different model and investment portfolios using five
fund companies, five target dates and three different levels of investor aggression.
2. Use the Analytic Hierarchy Process to propose a suitable (model) portfolio for a “typical” 50 year old investor who plans to retire in 2020.
3. Select the fund management company’s 2020 target fund to form the core holding for the portfolio.
4. Select two more complementary funds to accommodate varying investor risk tolerance and reduce the tracking error between the model portfolio and the proposed portfolio.
5. We will use mean-variance optimization to minimize the tracking error between the model portfolio and the proposed portfolio.
6. We will repeat steps 3 & 4 for two other investors who will retire in 2020. One is more conservative and one is more aggressive than our initial study.
7. We will Repeat steps 3 and 4 for investors who are will (or have) retired in 2000, 2010, 2030 and 2040 at 65 to 70 years of age.
8. Repeat steps 1-6 for five different fund families.

The Analytical Hierarchy Process
u A wide body of literature indicates the AHP is useful when making complex decisions involving multiple criteria.
u Thomas Saaty, a professor at the University of Pittsburgh, developed the AHP as a way to improve complex decision making and to identify and weight selection criteria.
u AHP can capture both subjective and objective evaluation measures.
u AHP provides an effective means to deal with, analyzing the data collected for the criteria and expediting the decision-making process.
u AHP has been proven in practice to be a useful mechanism for checking the consistency of the evaluation measures and reducing bias in decision making.

Complementary Fundsu Investors of the same age and retirement target differ in their ability and
willingness to assume risk in pursuit of higher returnu Complementary funds:
– Allow the financial planner to vary the level of risk while keeping the retirement target constant.
– Reduce the tracking error between the suitable portfolio and the lifecycle fund’s asset allocation.
– Provide additional diversification or opportunity for active return enhancement.– If investor’s risk tolerance varies with wealth (and other factors that determine
leverage), then the investor can keep the lifecycle allocation unchanged while rebalancing the complementary funds between stocks and bonds. This will normally happen as returns vary from their long-term expectation.
u Trial and error (lots of error) indicates that good candidate complementary funds invest in:
– Global Stock– Global Bonds– Equity Income – to balance AHP’s desired value tilt against a growth tilt that we see in
some (but not most) life-cycle funds, see slides 18, 20 and 21.

Vary the Retirement Horizon from 2000 to 2040
Assume:1. All investors intend to retire between 65 and 70.2. Increasing life spans and pressure on social security may
extend this even further for investors currently 40 years of ageand younger.
3. The 30 year old investor has a near term spending goal: purchasing a first house.
4. Older investors who are still working have incomes and savings that increase by one level per decade of age, except that real income does not increase from age 50 to 60.
5. Younger investors are more optimistic about future income growth relative to inflation.
6. Younger investors will prefer a more aggressive allocation consistent with their higher level of optimism.

Comparisons of the Fund Families
u The next three pages of slides in your handouts compare the five families with regard to:– The relative allocation between the 2020 lifecycle fund, the
bond fund and the stock fund vs. the investor’s ability and willingness to assume investment risk.
– The relative allocation between the target date lifecycle fund, the bond fund and the stock fund vs. the fund’s target date.
– The performance of the 2020 target fund for the “typical” investor vs. the AHP portfolio, which is constant for all fund families. Although this is in-sample optimize performance, these graphs give us the feel for the effects of tracking error and alpha on cumulative performance.

Conclusionsu The Analytic Hierarchy Process can be used to quickly create a model
portfolio for an investor whose main goal is a retirement planning.u Portfolio optimization using the model portfolio as a benchmark can create a
portfolio that combines a lifecycle fund and two or more complementary funds to best fit the model portfolio. Complementary funds:– Vary the risk for investors that are more or less aggressive than the typical
investor with the same retirement horizon.– Allow the investor to leave the allocation to the lifecycle fund unchanged while
varying the allocation between the complementary funds as wealth changes due to investment returns or other factors unique to the investor.
– Improve active performance vs. the model portfolio.u Life cycle funds will comprise between 40% and 60% of the weight of
portfolio for most investors between 30 and 70 years old, depending on:– fund company– target date– the investor’s specific ability and willingness to assume investment risk.
