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

Ahead of the Nifty weekly expiry on Thursday, May 29, 2025, the National Stock Exchange (NSE) has not placed any stocks under the futures and options (F&O) trading ban list.

An F&O ban is typically imposed when the open interest in a stock crosses 95% of the market-wide position limit (MWPL). Since no stock has breached this threshold, all remain available for trading in both the derivatives and cash segments.

Why is a Stock Put Under F&O Ban?

A stock is added to the F&O ban list by the National Stock Exchange (NSE) when the open interest in its futures and options contracts goes beyond 95% of the total market-wide position limit (MWPL). When this happens, traders can only close or reduce their existing positions. Starting any new F&O positions is not allowed and may lead to penalties.

Even though trading is restricted in the F&O segment, the stock can still be traded normally in the cash (equity) market.

What Is Nifty Weekly Expiry Day?

Nifty’s weekly futures and options (F&O) contracts usually expire every Thursday. But if Thursday is a market holiday, the expiry happens a day earlier. All contracts are settled based on the regular market closing time on expiry day.

This rule also applies to individual stocks. On trading platforms like MarketWatch, weekly expiry contracts are shown under the monthly contract section in the final week to keep the format uniform.

Conclusion

With no stocks under the F&O ban, traders can expect smoother participation in both the cash and derivatives segments. However, continued market weakness and expiry-related volatility may keep investors on edge.
