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

Ahead of the Nifty’s weekly expiry on Tuesday, January 20, 2026, the National Stock Exchange (NSE) has placed one stock under the Futures and Options (F&O) trading ban. 

Such a restriction is imposed when the open interest in a stock exceeds 95% of the market-wide position limit (MWPL). During the ban period, no new derivative positions are allowed, though trading in the cash market remains unaffected.

The stocks under the F&O ban for January 20 are :

Steel Authority of India Limited (SAIL)

Steel Authority of India Limited (SAIL) share price closed at ₹149.00 on Jan 19, down 0.25%. SAIL share price traded between the day's low and high of ₹147.68 and ₹150.21, respectively.

Sammaan Capital Limited 

On Jan 19, Sammaan Capital stock (NSE: SAMMAANCAP) closed at ₹140.70, up from its previous close of ₹140.08. It opened at ₹139.50 and moved between an intraday high of ₹142.73 and a low of ₹139.40. The Volume Weighted Average Price (VWAP) stood at ₹141.09. 

Why Is a Stock Under F&O Ban?

As per NSE guidelines, a stock is added to the F&O ban list when its open interest crosses 95% of the market-wide position limit (MWPL).

During the ban period:

• No fresh F&O positions are permitted
• Only existing positions can be squared off
• Any violation of the rules may attract penalties

This measure is designed to rein in excessive speculation and maintain orderly market conditions, especially during high-volatility phases such as expiry days.
