On April 29, the Nifty 50 closed at 24,335.95, up 7.45 points or 0.03%, while the BSE Sensex ended higher by 70.01 points or 0.09%, settling at 80,288.38.
This week’s Nifty contracts are set to expire on Wednesday, April 30, instead of the usual Thursday, as the stock markets and banks will remain closed on Thursday due to Labour Day.
Ahead of the Nifty weekly expiry on Wednesday, April 30, 2025, the National Stock Exchange (NSE) has placed 1 stock under a trading ban in the futures and options (F&O) segment.
The F&O ban is triggered when the open interest in any stock exceeds 95% of the market-wide position limit (MWPL). While trading in derivatives is restricted, this stock remains available for trading in the cash market.
The stock under the F&O ban for April 30 includes:
On April 29, 2025, RBL Bank’s share price declined 1.93% to close at ₹203.15. The stock opened at ₹205.49 and traded between ₹202.42 and ₹207.22 during the day. A total of 115.73 lakh shares were traded, with a turnover of ₹237.02 crore, according to exchange data.
The stock’s current market capitalization stands at ₹12,348.10 crore, with a price-to-earnings (P/E) ratio of 17.56x. RBL Bank is part of the Nifty 500 index and operates within the Private Sector Bank industry.
The National Stock Exchange (NSE) places a stock under the F&O ban listwhen the open interest in its derivative contracts exceeds 95% of the market-wide position limit (MWPL). Traders are only allowed to reduce existing positions through offsetting trades. Opening new positions is strictly prohibited and could attract penalties.
Despite the restrictions in the F&O segment, the stock continues to be available for trading in the cash market.
Nifty weekly futures and options (F&O) contracts typically expire every Thursday. However, if Thursday is a trading holiday, the expiry is advanced to the previous session. All contracts are settled at the normal market closing time on expiry day.
For individual securities, the same rule applies. In trading platforms like MarketWatch, weekly expiry contracts appear under the monthly contract header during the final week, ensuring consistent classification.
As observed, the F&O ban mechanism acts as a regulatory tool to curb excessive speculation and maintain market stability during high-activity sessions like weekly expiries. With a stock under the ban on April 30, 2025, it’s crucial for traders to monitor open interest levels and comply with exchange guidelines.
Staying updated with such developments ensures informed participation in the derivatives segment, especially during periods of heightened market action such as the weekly expiry cycle.
