India’s benchmark indices closed in the red on June 23. The BSE Sensex dropped 511.38 points to end at 81,896.79, while the Nifty 50 lost 140.50 points to settle at 24,971.90, down 0.62% and 0.56% respectively.
As we approach the weekly F&O expiry on June 24, 2025, Biocon and RBL Bank have been added to the F&O ban list.
As the Sensex weekly expiry approaches on Tuesday, June 24, 2025, the National Stock Exchange (NSE) has imposed a trading ban on 2 stocks in the futures and options (F&O) segment.
The ban was triggered as these securities breached 95% of the market-wide position limit (MWPL). While trading in F&O for this stock is restricted, it remains available for trading in the cash market.
The stock under the F&O ban for June 24 include:
Biocon closed marginally higher by 0.14% at ₹352.10. The stock opened at ₹347.15 and touched an intraday high of ₹355.60, reflecting modest range-bound movement. Biocon's 52-week high is ₹404.60, while its 52-week low is ₹290.80.
The company has a full market capitalization of ₹42,273.13 crore and a free-float market cap of ₹15,818.56 crore. Despite low volatility, the stock’s high open interest has led to its inclusion in the F&O ban list.
RBL Bankgained 2.56% to close at ₹234.10, rising steadily throughout the session from its open at ₹223.70. The stock’s intraday high of ₹234.85 brings it closer to its 52-week high of ₹270.40. With a price-to-earnings ratio of 14.53 and a low price-to-book ratio of 0.92, RBL Bank has a full market cap of ₹14,256.92 crore.
It remains under investor radar, particularly within the private banking sector, amid increasing volumes and growing open interest in F&O contracts.
The weekly expiry of Sensex options contracts occurs every Tuesday. If Tuesday is a trading holiday, the expiry is advanced to the previous trading session.
Settlement of contracts is done at the regular market close on expiry day or subsequently as determined by the exchange.
Notably, weekly expiry contracts are often reflected without specific expiry dates on the MarketWatch terminal, appearing instead as monthly series, with only the month and strike prices shown.
With the market closing in the red ahead of the weekly expiry, investor caution is evident. The inclusion of Biocon and RBL Bank in the F&O ban list highlights rising open interest amid volatile cues. Traders should monitor position limits closely and exercise prudence while dealing in these counters, especially as expiry-related volatility may persist. Staying informed and managing risk remains key in the current market environment.
