Derivative
INTRODUCTION:
Derivative is a product whose value is derived from
the value of one or more basic variables,
called bases (underlying asset, index, or reference
rate), in a contractual manner. The underlying asset can be equity, forex,
commodity or any other asset. For example, wheat farmers may wish to sell their
harvest at a future date to eliminate the risk of a change in prices by that
date. Such a transaction is an example of a derivative. The price of this
derivative is driven by the spot price of wheat which is the “underlying”.
In the Indian context the Securities Contracts
(Regulation) Act, 1956 (SC(R)A) defines
“derivative” to include –
1. A security derived from a debt
instrument, share, loan whether secured or unsecured, risk instrument or contract
for differences or any other form of security.
2. A contract which derives its
value from the prices, or index of prices, of underlying securities.
Derivatives are securities under the SC(R)A and hence the trading
of derivatives is governed
by the regulatory framework under the SC(R)A.
PARTICIPANTS:
The following three broad categories of participants -
hedgers, speculators,
and
arbitrageurs trade in the derivatives market. Hedgers face risk associated with
the price of an asset. They use futures or options markets to reduce or
eliminate this risk. Speculators wish to bet on future movements in the price
of an asset. Futures and options contracts can give them an extra leverage;
that is, they can increase both the potential gains and potential losses in a
speculative venture. 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.
TYPES OF DERIVATIVES:
The most commonly used derivatives contracts are forwards, futures
and options.
Forwards: A
forward contract is a customized contract between two entities, where
settlement takes place on a specific date in the future at today’s pre-agreed
price.
Futures:
A futures contract is an agreement between two parties to buy or sell an asset
at a certain time in the future at a certain price. Futures contracts are
special types of forward contracts in the sense that the former are
standardized exchange-traded contracts.
Options: Options are of two types - calls and puts. Calls
give the buyer the right but not the obligation to buy a given quantity of the
underlying asset, at a given price on or before a given future date. Puts
give the buyer the right, but not
the obligation to sell a given quantity of the underlying asset at a
given price on or before a given
date.
Warrants: Options generally have lives of upto one year, the
majority of options traded on options
exchanges having a maximum maturity
of nine months. Longer-dated options are called warrants
and are generally traded
over-the-counter.
LEAPS: The acronym LEAPS means Long-Term Equity
Anticipation Securities. These are options
having a maturity of upto three
years.
Baskets: Basket options are options on portfolios of
underlying assets. The underlying asset is usually a moving average of a basket
of assets. Equity index options are a form of basket options.
Swaps: Swaps are private agreements between two parties to
exchange cash flows in the future according to a prearranged formula. They can
be regarded as portfolios of forward contracts. The two
commonly used swaps are :
_ Interest rate swaps: These entail swapping only the interest related cash flows between
the
parties in the same currency.
_ Currency swaps:
These entail swapping both principal and interest between the parties,
with the cashflows in one direction
being in a different currency than those in the opposite
direction.
Swaptions:
Swaptions are options to buy or sell a swap that will become operative at the
expiry of the
options. Thus a swaption is an option on a forward
swap. Rather than have calls and puts, the
swaptions market has receiver swaptions and payer swaptions.
A receiver swaption is an option to
receive fi xed and pay floating. A
payer swaption is an option to pay fi xed and receive floating.
FACTORS
DRIVING THE GROWTH OF FINANCIAL DERIVATIVES:
1. Increased volatility in asset prices in financial
markets,
2. Increased integration of national financial markets
with the international markets,
3. Marked improvement in communication facilities and
sharp decline in their costs,
4. Development of more sophisticated risk management
tools, providing economic agents a wider
choice of risk management strategies, and
5. Innovations in the derivatives markets, which
optimally combine the risks and returns over a large
number of fi nancial assets leading to higher returns,
reduced risk as well as transactions costs as
compared to individual fi nancial
assets.
DERIVATIVES MARKET 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. The trading in
index options commenced in June 2001 and the trading in options on individual
securities commenced in July 2001. Futures contracts on individual stocks were
launched in November 2001. Trading and settlement in derivative contracts is
done in accordance with the rules, byelaws, and regulations of the respective
exchanges and their clearing house/corporation duly approved by SEBI and
notified in the official gazette.
ECONOMIC
FUNTIONS:
The derivatives market performs a number of economic
functions. First, prices in an
organized derivatives market reflect the perception of
market participants about the future and lead the prices of underlying to the
perceived future level. The prices of derivatives converge with the prices of
the underlying at the expiration of the derivative contract. Thus derivatives
help in discovery of future as well as current prices. Second, the derivatives
market helps to transfer risks from those who have them but may not like them
to those who have an appetite for them. Third, derivatives, due to their
inherent nature, are linked to the underlying cash markets. With the
introduction of derivatives, the underlying market witnesses higher trading
volumes because of participation by more players who would not otherwise
participate for lack of an arrangement to transfer risk. Fourth, speculative
trades shift to a more controlled environment of derivatives market. In the
absence of an organized derivatives market, speculators trade in the underlying
cash markets. Margining, monitoring and surveillance of the activities of
various participants become extremely difficult in these kind of mixed markets.
Fifth, an important incidental benefit that flows from derivatives trading is
that it acts as a catalyst for new entrepreneurial activity. The derivatives
have a history of attracting many bright, creative, well-educated people with
an entrepreneurial attitude. They often energize others to create new
businesses, new products and new employment opportunities, the benefit of which
are immense. Finally, derivatives markets
help
increase savings and investment in the long run. Transfer of risk enables
market participants to expand their volume of activity.
Futures terminology
_ Spot price:
The price at which an asset trades in the spot market.
_ Futures price:
The price at which the futures contract trades in the futures market.
Contract cycle:
The period over which a contract trades. The index futures contracts on the NSE
have one-month, two-months and three-months expiry
cycles which expire on the last Thursday of
the month. Thus a January expiration contract expires
on the last Thursday of January and a February
expiration contract ceases trading on the last
Thursday of February. On the Friday following the last
Thursday, a new contract having a three-month expiry
is introduced for trading.
Expiry date:
It is the date specifi ed in the futures contract. This is the last day on
which the contract
will be traded, at the end of which it will cease to
exist.
Contract
size: The amount of asset that has to
be delivered under one contract. For example:The contract size of Relaiance’s
future is 150.
Basis: In
the context of financial futures, basis can be defined as the futures price
minus the spot
price. There will be a different basis for each
delivery month for each contract. In a normal market,
basis will be positive. This reflects that futures
prices normally exceed spot prices.
Cost of carry:
The relationship between futures prices and spot prices can be summarized in
terms
of what is known as the cost of carry. This measures
the storage cost plus the interest that is paid to
finance the asset less the income earned on the asset.
Initial margin:
The amount that must be deposited in the margin account at the time a futures
contract
is first entered into.
Marking-to-market: In the futures market, at the end of each trading day, the margin
account is
adjusted to reflect the investor’s gain or loss
depending upon the futures closing price.
Maintenance margin: This is somewhat lower than the initial margin. This is set to
ensure that the
balance in the margin account never becomes negative.
If the balance in the margin account falls
below the maintenance margin, the investor receives a
margin call and is expected to top up the
margin account to the initial margin level before
trading commences on the next day.
Option terminology
_ Index options:
These options have the index as the underlying. Some options are European while
others are American. Like index
futures contracts, index options contracts are also cash settled.
Stock
options: Stock options are options on individual stocks. A contract gives
the holder the right to buy or sell shares at the specified price.
Buyer of an option: The buyer of an option is the one who by paying the option premium
buys the
right but not the obligation to exercise his option on
the seller/writer.
_
Writer of an option: The writer of a call/put option is the one who receives the option
premium and
is thereby obliged to sell/buy the
asset if the buyer exercises on him.
Option price:
Option price is the price which the option buyer pays to the option seller. It
is also
referred to as the option premium.
Expiration date:
The date specifi ed in the options contract is known as the expiration date,
the
exercise date, the strike date or
the maturity.
Strike price:
The price specifi ed in the options contract is known as the strike price or
the exercise
price.
In-the-money option: An in-the-money (ITM) option is an option that would lead to a
positive
cashflow to the holder if it were exercised
immediately. A call option on the index is said to be
in-the-money when the current index stands at a level
higher than the strike price (i.e. spot price _ strike
price). If the index is much higher than the strike price, the call is said to
be deep ITM. In the
case of a put, the put is ITM if the index is below
the strike price.
_ At-the-money option: An at-the-money (ATM) option is an option that would lead to zero
cashflow
if it were exercised immediately. An option on the
index is at-the-money when the current index
equals the strike price (i.e. spot price = strike
price).
_
Out-of-the-money option: An out-of-the-money (OTM) option is an option that
would lead to a
negative cashflow it it were exercised immediately. A
call option on the index is out-of-the-money
when the current index stands at a level which is less
than the strike price (i.e. spot price _ strike
price). If the index is much lower than the strike
price, the call is said to be deep OTM. In the case
of a put, the put is OTM if the
index is above the strike price.
