OPTIONS FUTURES AND DERIVATIVES
SANJAY MEHROTRA
The Nature of Derivatives
Derivatives are financial instruments that have no intrinsic value, but derive their value from something else. They hedge the risk of owning things that are subject to unexpected price fluctuations, e.g. foreign currencies, crude oil, stocks and government bonds.
The term "derivative" indicates that it has no independent value, i.e. its value is entirely "derived" from the value of the cash asset. A derivative contract or product, or simply "derivative", is to be sharply distinguished from the underlying cash asset, i.e. the asset bought/sold in the cash market on normal delivery terms.
The price of the cash instrument is referred to as the "underlying" price.
Examples of cash instruments include actual shares in a company, physical stocks of commodities, foreign exchange, etc.
Examples of Derivatives
Forward Contracts Futures Contracts Swaps Options
FORWARD CONTRACTS
Forward contract is an agreement entered between two parties to buy or sell an asset at a future date for an agreed price. Forward contract is not traded on an exchange.
For example, a foreign exchange forward contract requires party A to buy (and party B to sell) 1 million euros for U.S. dollars at $1.0865 per euro say, a year from now.
Main features of forward contracts They are bilateral contracts and
hence exposed to counter-party risk.
Each contract is custom designed, and hence is unique in terms of contract size, expiration date and the asset type and quality.
Main features of forward contracts… The contract price is generally not
available in public domain. The contract has to be settled by
delivery of the asset on expiration date. In case, the party wishes to reverse the
contract, it has to compulsorily go to the same counter party, which being in a monopoly situation can command the price it wants.
FUTURES Futures contracts are like forwards,
except that they are highly standardized. A futures contract is an agreement
between two parties to buy or sell a specified quantity and quality of asset at a certain time in future at a certain price agreed at the time of entering into the contract on the futures exchange.
Futures… Futures contracts are standardized
tradable contracts. They are standardized in terms of
size, expiration date and all other features.
They are traded on specially designed exchanges in an environment of stringent financial safeguards.
Futures… They are liquid and transparent. Their
market prices and trading volumes are regularly reported.
The futures trading system has effective safeguards against defaults in the form of Clearing Corporation guarantees for trades and the daily cash adjustment (mark-to-market) to the accounts of trading members based on daily price change.
OPTIONS An Option is the right but not the
obligation of the holder, to buy or sell underlying asset by a certain date at a certain price.
CALL OPTIONS
There are two types Options: A call option is a contract that
gives the owner the right, but not obligation to buy the underlying asset by a specified date at a specified price.
PUT OPTIONS
A put option is a contract that gives the owner the right, but not obligation to sell the underlying asset by a specified date at a specified price.
Call option An example:A call option will give the investor the right
to buy, say, crude oil at $58 a barrel over a 3 months period.
If the price rise above the strike price of $58 before the option expires (i.e., before the 3 months are over), then the investor can exercise the option and capture a profit equal to the market price less $58.
CALL OPTION example
Say for example the price of oil rises to $60. The investor will exercise the option by buying oil at US$58 and then sells it in the open market at $60 thus pocketing the $2 profit.
CALL OPTION example
If, on the other hand, the price never rises above $58 or even falls below that level, then the option expires worthless or "out of the money" and the investor loses the money (known as the option premium) he paid for the option.
Put Option
A put option is similar. Take the example of coffee. A put option
would provide an investor the right to sell coffee at a strike or exercise price of $0.65 per pound;
if the price were to fall to say $0.60, then the investor would be able to exercise the put option (i.e., sell the coffee at $0.65 while buying from the open market at US$0.60) and gain $0.05 for every pound of coffee covered by the options contract.
SWAPS
Swaps are private agreements between two parties to exchange cash flows in the future according to a prearranged formula.
The two commonly used swaps are :1) Interest rate swap: These entail
swapping only the interest related cash flows between the parties in the same currency. This involves the exchange of fixed-rate and floating-rate interest payments for a fixed par value
2)Currency swap: These entail swapping both principal and interest between the parties, with the cash flows in one direction being in a different currency than those in the opposite direction. Currency swap is the exchange of interest payments in different currencies
Worldwide derivatives market The derivatives market is mostly
made up of derivatives based on: Interest rates: ( ~65% of the
market). Currencies: (~25%). Options and
swaps on foreign exchange. Equity: (~5-10%). Index futures,
Index swaps, etc. Commodities: (~0-5%).
Uses of derivatives:
They are useful in reallocating risk either across time or among individuals with different risk-bearing preferences.
Uses of derivatives… One kind of passing-on of risk is mutual
insurance between two parties who face the opposite kind of risk. For example, in the context of currency fluctuations, exporters face losses if the rupee appreciates and importers face losses if the rupee depreciates. By forward contracting in the dollar-rupee forward market, they supply insurance to each other and reduce risk.
How derivatives markets work
Derivatives are traded in two kinds of markets: in exchanges and in over-the-counter (OTC) markets.
Derivatives Markets
Exchange traded Traditionally exchanges have used
the open-outcry system, but increasingly they are switching to electronic trading
Contracts are standard there is virtually no credit risk
Derivatives Markets…
Over-the-counter (OTC) A computer- and telephone-linked
network of dealers at financial institutions, corporations, and fund managers
Contracts can be non-standard and there is some small amount of credit risk
Over-the-Counter Exchange-TradedPrivate transaction Public price quote
Credit risk Limited credit risk due to clearing house
Wide range of structures and contract size
Standard contracts and size
Many currencies Major currencies
Any maturity Standard expiration dates
Key Differences—OTC vs. Exchange-Traded Derivatives
The participants in a derivatives market Hedgers use futures or options markets
to reduce or eliminate the risk associated with price of an asset.
Speculators use futures and options contracts to get extra leverage in betting on future movements in the price of an asset. They can increase both the potential gains and potential losses by usage of derivatives in a speculative venture.
Participants
Arbitrageurs are in business to take advantage of a discrepancy between prices in two different markets. If, for example, they see the futures price of an asset getting out of line with the cash price, they will take offsetting positions in the two markets to lock in a profit.
Development of Derivatives in India: Derivatives trading commenced in India
in June 2000 after SEBI granted the final approval to this effect in May 2000.
SEBI permitted the derivative segments of two stock exchanges, NSE and BSE, and their clearing house/corporation to commence trading and settlement in approved derivatives contracts.
To begin with, SEBI approved trading in index futures contracts based on S&P CNX Nifty and BSE–30(Sensex) index. This was followed by approval for trading in options based on these two indexes and options on individual securities.
Beginning of Exchange traded derivatives in India
