Piramal Enterprises, Hindustan Copper To Birlasoft: NSE To Exclude Five Securities From F&O Effective Aug. 1

The National Stock Exchange announced on Wednesday the exclusion of five securities from the F&O market, effective Aug. 1, 2025.

However, the existing unexpired contracts of expiry months May 2025, June 2025 and July 2025 would continue to be available for trading till their respective expiry and new strikes would also be introduced in the existing contract months

Aarti Industries Ltd., Birlasoft Ltd., Hindustan Copper Ltd., Mahanagar Gas Ltd., Piramal Enterprises Ltd., are the five securities to be excluded from the F&O market effective Aug. 1.

Accordingly, no contracts shall be available for trading in the above-mentioned securities with effect from Aug. 1, 2025, the filing said.

On Aug. 30, the Securities and Exchange Board of India came up with several changes to its criteria for the inclusion and removal of stocks from the derivatives segment.

Under the revised rules, the median quarter sigma order size for stocks has been increased from Rs 25 lakh to Rs 75 lakh. MQSOS, a metric that measures a stock's liquidity, now requires a higher threshold, making it more difficult for stocks to be manipulated.

Additionally, the minimum market-wide position limit has been tripled from Rs 500 crore to Rs 1,500 crore, and the minimum average daily delivery value has been raised 3.5 times from Rs 10 crore to Rs 35 crore.

Stocks that meet these revised criteria based on their performance in the cash market over a rolling six-month period will be eligible for entry into the derivatives segment. Conversely, stocks that fail to meet the criteria for three consecutive months will be removed from the derivatives segment, although existing contracts will remain valid until their expiry.

Once a stock is removed from the derivatives segment, it cannot be reintroduced for a year from the date it was last traded in this segment.
