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

Ahead of the Nifty’s weekly expiry on Tuesday, February 24, 2026, the National Stock Exchange (NSE) has placed SAIL 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 February 24 is:

SAIL

On February 23, 2026, SAIL share (NSE: SAIL) closed at ₹156.68, down by 1.30% from its previous close of ₹158.75. During the day, SAIL shares traded between high and low of ₹159.70 and ₹155.25, respectively.

Why Is a Stock Under F&O Ban?

A stock enters the Futures & Options (F&O) ban list on the National Stock Exchange (NSE) when the open interest in its derivative contracts crosses 95% of the Market-Wide Position Limit (MWPL). This measure is designed to control excessive speculation and ensure smooth market functioning.

During the ban:

• No new F&O positions can be initiated in that stock.
• Traders may only square off or reduce existing positions.
• Any breach of these rules can lead to penalties and disciplinary action by the exchange.

This mechanism is especially important during periods of high volatility—such as contract expiry weeks—to prevent sharp price swings and maintain market stability.

About Nifty Weekly Expiry

Nifty 50 Futures & Options contracts expire every Tuesday. If Tuesday happens to be a trading holiday, the expiry is shifted to the previous trading day. Settlement for all contracts is based on the closing price on the day of expiry.

For convenience, some trading platforms display weekly contracts under the “monthly” tab during expiry week. This is purely a technical arrangement and does not change the actual expiry rules.

Conclusion

Market sentiment remains subdued as traders tread carefully ahead of Nifty’s weekly expiry. With SAIL currently under the F&O ban, participants are likely to shift focus to cash market opportunities while awaiting expiry cues. The restricted derivatives activity may also limit speculative momentum, adding to the cautious tone in the broader market.
