Stock Under F&O Ban on Nifty’s Weekly Expiry Day

Ahead of the Nifty’s weekly expiry on Tuesday, December 30, 2025, the National Stock Exchange (NSE) has placed one stock under the Futures and Options (F&O) trading ban:

This restriction is enforced when the open interest in the stock crosses 95% of the market-wide position limit (MWPL). While fresh derivative positions are disallowed, the stock continues to be available for trading in the cash market.

The stock under the F&O ban for December 30 is:

Sammaan Capital Limited 

On December 29, Sammaan Capital stock (NSE: SAMMAANCAP) closed at ₹141.74, up from its previous close of ₹139.88. It opened at ₹140.00 and moved between an intraday high of ₹143.43 and a low of ₹139.23. The Volume Weighted Average Price (VWAP) stood at ₹141.91. 

Trading volumes remained at 128.81 lakh shares exchanged, generating a traded value of ₹182.79 crore. The company's total market capitalisation was reported at ₹11,741.22 crore, with a free float market cap of ₹10,900.02 crore. 

Why Is a Stock Under F&O Ban?

A stock is placed under the F&O ban list when open interest exceeds 95% of MWPL, as per NSE guidelines.

During the ban:

• New F&O positions cannot be created
• Only existing positions may be squared off
• Traders breaching the rules may incur penalties

This safeguard is meant to curb speculation and ensure orderly market function during high-activity periods like expiry days.
