Derivative products have been introduced in a phased manner starting with Index Futures Contracts in June 2000. Index Options and Stock Options were introduced in June 2001 and July 2001 followed by Stock Futures in November 2001. Sectoral indices were permitted for derivatives trading in December 2002. Interest Rate Futures on a notional bond and T-bill priced off ZCYC have been introduced in June 2003 and exchange traded interest rate futures on a notional bond priced off a basket of Government Securities were permitted for trading in January 2004.

* What is the eligibility criteria for stocks on which derivatives trading may be permitted?

A stock on which stock option and single stock future contracts are proposed to be introduced is required to fulfill the following broad eligibility criteria:-

o The stock shall be chosen from amongst the top 500 stock in terms of average daily market capitalisation and average daily traded value in the previous six month on a rolling basis.

o The stock’s median quarter-sigma order size over the last six months shall be not less than Rs.1 Lakh. A stock’s quarter-sigma order size is the mean order size (in value terms) required to cause a change in the stock price equal to one-quarter of a standard deviation.

o The market wide position limit in the stock shall not be less than Rs.50 crores.

A stock can be included for derivatives trading as soon as it becomes eligible. However, if the stock does not fulfill the eligibility criteria for 3 consecutive months after being admitted to derivatives trading, then derivative contracts on such a stock would be discontinued.

* What is minimum contract size?

The Standing Committee on Finance, a Parliamentary Committee, at the time of recommending amendment to Securities Contract (Regulation) Act, 1956 had recommended that the minimum contract size of derivative contracts traded in the Indian Markets should be pegged not below Rs. 2 Lakhs. Based on this recommendation SEBI has specified that the value of a derivative contract should not be less than Rs. 2 Lakh at the time of introducing the contract in the market. In February 2004, the Exchanges were advised to re-align the contracts sizes of existing derivative contracts to Rs. 2 Lakhs. Subsequently, the Exchanges were authorized to align the contracts sizes as and when required in line with the methodology prescribed by SEBI.

* What is the lot size of a contract?

Lot size refers to number of underlying securities in one contract. The lot size is determined keeping in mind the minimum contract size requirement at the time of introduction of derivative contracts on a particular underlying.

For example, if shares of XYZ Ltd are quoted at Rs.1000 each and the minimum contract size is Rs.2 lacs, then the lot size for that particular scrips stands to be 200000/1000 = 200 shares i.e. one contract in XYZ Ltd. covers 200 shares.

* What is corporate adjustment?

The basis for any adjustment for corporate action is such that the value of the position of the market participant on cum and ex-date for corporate action continues to remain the same as far as possible. This will facilitate in retaining the relative status of positions viz. in-the-money, at-the-money and out-of-the-money. Any adjustment for corporate actions is carried out on the last day on which a security is traded on a cum basis in the underlying cash market. Adjustments mean modifications to positions and/or contract specifications as listed below:

1. Strike price

2. Position

3. Market/Lot/ Multiplier

The adjustments are carried out on any or all of the above based on the nature of the corporate action. The adjustments for corporate action are carried out on all open, exercised as well as assigned positions.

The corporate actions are broadly classified under stock benefits and cash benefits. The various stock benefits declared by the issuer of capital are:

o Bonus

o Rights

o Merger/ demerger

o Amalgamation

o Splits

o Consolidations

o Hive-off

o Warrants, and
