Introduction

Eligibility Criteria for selection of Securities

The eligibility of a stock / index for trading in Derivatives segment is based upon the criteria laid down by SEBI through various circulars issued from time to time. The latest circular issued in this respect is circular No. : SEBI/DNPD/Cir-31/2006 dated September 22, 2006. Based on various circulars, the following criteria will be adopted by the Exchange w.e.f September 22, 2006, for selecting stocks and indices on which Futures & Options contracts would be introduced.

Eligibility criteria of stocks

The stock shall be chosen from amongst the top 500 stocks in terms of average daily market capitalisation and average daily traded value in the previous six months on a rolling basis.
The stock’s median quarter-sigma order size over the last six months shall be not less than Rs. 0.10 million (Rs. 1 lac). For this purpose, a stock’s quarter-sigma order size shall mean the order size (in value terms) required to cause a change in the stock price equal to one-quarter of a standard deviation.
The market wide position limit in the stock shall not be less than Rs. 500 million (Rs. 50 crores). The market wide position limit (number of shares) shall be valued taking the closing prices of stocks in the underlying cash market on the date of expiry of contract in the month. The market wide position limit of open position (in terms of the number of underlying stock) on futures and option contracts on a particular underlying stock shall be 20% of the number of shares held by non-promoters in the relevant underlying security i.e. free-float holding.

Continued Eligibility

For an existing stock to become ineligible, the criteria for market wide position limit shall be relaxed upto 10% of the criteria applicable for the stock to become eligible for derivatives trading.
To be dropped out of Derivatives segment, the stock will have to fail the relaxed criteria for 3 consecutive months.
If an existing security fails to meet the eligibility criteria for three months consecutively, then no fresh month contract shall be issued on that security.
Further, the members may also refer to circular no. NSCC/F&O/C&S/365 dated August 26, 2004, issued by NSCCL regarding Market Wide Position Limit, wherein it is clarified that a stock which has remained subject to a ban on new position for a significant part of the month consistently for three months, shall be phased out from trading in the F&O segment.
However, the existing unexpired contracts may be permitted to trade till expiry and new strikes may also be introduced in the existing contract months.

Re-introduction of dropped stocks

A stock which is dropped from derivatives trading may become eligible once again. In such instances, the stock is required to fulfill the eligibility criteria for three consecutive months to be re-introduced for derivatives trading.

Introduction

Eligibility criteria of Indices

Futures & Options contracts on an index can be introduced only if 80% of the index constituents are individually eligible for derivatives trading.
However, no single ineligible stock in the index shall have a weightage of more than 5% in the index.
The index on which futures and options contracts are permitted shall be required to comply with the eligibility criteria on a continuous basis.
SEBI has subsequently modified the above criteria, vide its clarification issued to the Exchange The Exchange may consider introducing derivative contracts on an index if the stocks contributing to 80% weightage of the index are individually eligible for derivative trading.
However, no single ineligible stocks in the index shall have a weightage of more than 5% in the index.
The above criteria is applied every month, if the index fails to meet the eligibility criteria for three months consecutively, then no fresh month contract shall be issued on that index,
However, the existing unexpired contacts shall be permitted to trade till expiry and new strikes may also be introduced in the existing contracts.
The following procedure is adopted for calculating the Quarter Sigma Order Size :
1) The applicable VAR (Value at Risk) is calculated for each security based on the J.R. Varma Committee guidelines. (The formula suggested by J. R. Varma for computation of VAR for margin calculation is statistically known as ‘Exponentially weighted moving average (EWMA)’ method.
In comparison to the traditional method, EWMA has the advantage of giving more weight to the recent price movements and less weight to the historical price movements.)
2) Such computed VAR is a value (like 0.03), which is also called standard deviation or Sigma. (The meaning of this figure is that the security has the probability to move 3% to the lower side or 3% to the upper side on the next trading day from the current closing price of the security).
3) Such arrived at standard deviation (one sigma), is multiplied by 0.25 to arrive at the quarter sigma. (For example, if one sigma is 0.09, then quarter sigma is 0.09 * 0.25 = 0.0225)
4) From the order snapshots (taken four times a day from NSE’s Capital Market Segment order book) the average of best buy price and best sell price is computed which is called the average price.

5) The quarter sigma is then multiplied with the average price to arrive at quarter sigma price. The following example explains the same :

Security	XYZ
Best Buy (in Rs.)	306.45
Best Sell (in Rs.)	306.90
Average Price	306.70
One Sigma	0.009
Quarter sigma	0.00225
Quarter sigma price (Rs.) (Average Price *Quarter sigma)	0.70

6) Based on the order snapshot, the value of the order (order size in Rs.), which will move the price of the security by quarter sigma price in buy and sell side is computed. The value of such order size is called Quarter Sigma order size. (Based on the above example, it will be required to compute the value of the order (Rs.) to move the stock price to Rs. 306.00 in the buy side and Rs. 307.40 on the sell side. That is Buy side = average price – quarter sigma price and Sell side = average price + quarter sigma price).

Such an exercise is carried out for four order snapshots per day for all stocks for the previous six months period
7) Based on the order snapshot, the value of the order (order size in Rs.), which will move the price of the security by quarter sigma price in buy and sell side is computed.
The value of such order size is called Quarter Sigma order size. (Based on the above example, it will be required to compute the value of the order (Rs.) to move the stock price to Rs. 306.00 in the buy side and Rs. 307.40 on the sell side. That is Buy side = average price – quarter sigma price and Sell side = average price + quarter sigma price).
Such an exercise is carried out for four order snapshots per day for all stocks for the previous six months period 8) From the above determined quarter sigma order size (Rs.) for each order book snap shot for each security, the median of the order sizes (Rs.) for buy side and sell side separately, are computed for all the order snapshots taken together for the last six months.
9) The average of the median order sizes for buy and sell side are taken as the median quarter sigma order size for the security.
10) The securities whose median quarter sigma order size is equal to or greater than Rs. 0.1 million (Rs. 1 Lac) qualify for inclusion in the F&O segment.
Futures & Options contracts may be introduced on new securities which meet the above mentioned eligibility criteria, subject to approval by SEBI.
New securities being introduced in the F&O segment are based on the eligibility criteria which take into consideration average daily market capitalization, average daily traded value, the market wide position limit in the security, the quarter sigma values and as approved by SEBI. The average daily market capitalisation and the average daily traded value would be computed on the 15th of each month, on a rolling basis, to arrive at the list of top 500 securities.
Similarly, the quarter sigma order size in a stock would also be calculated on the 15th of each month, on a rolling basis, considering the order book snapshots of securities in the previous six months and the market wide position limit (number of shares) shall be valued taking the closing prices of stocks in the underlying cash market on the date of expiry of contract in the month.
The number of eligible securities may vary from month to month depending upon the changes in quarter sigma order sizes, average daily market capitalisation & average daily traded value calculated every month on a rolling basis for the past six months and the market wide position limit in that security. Consequently, the procedure for introducing and dropping securities on which option and future contracts are traded will be as stipulated by SEBI in its circular no. SEBI/DNPD/Cir-26/2004/07/16 dated July 16, 2004.
Selection criteria for mini derivative contracts:
Mini derivative contracts (Futures and options) shall be made available for trading on such indices/securities as specified by SEBI from time to time.
Eligibility criteria for long term option contracts
Vide its circular no. SEBI/DNPD/Cir-34/2008 dated January 11, 2008 SEBI has specifically permitted introduction of option contracts with longer tenure on S&P CNX Nifty index.
Selection criteria for unlisted companies
For unlisted companies coming out with initial public offering, if the net public offer is Rs. 500 crs. or more, then the Exchange may consider introducing stock options and stock futures on such stocks at the time of its’ listing in the cash market.
