Steel Authority of India Share Price Performance  

As of May 25, 2026, at 3:30 PM, Steel Authority of India share price on NSE was closed at ₹198.32 down by 1.44% from the previous closing price.  

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 Monthly Expiry 

Nifty 50 Futures & Options contracts expire on the last Tuesday of every month. 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.
