Ahead of the Nifty’s weekly expiry, the National Stock Exchange (NSE) has placed three stocks under the Futures & Options (F&O) trading ban:

• Bandhan Bank Limited
• Kaynes Technology India Limited
• Sammaan Capital Limited

The ban is triggered when the open interest in a stock’s derivatives contracts exceeds 95% of the Market-Wide Position Limit (MWPL). While new derivative positions cannot be initiated, the stocks remain available for trading in the cash segment.

Why Are Stocks Placed Under F&O Ban?

A stock enters the F&O ban list when its open interest exceeds 95% of the MWPL. This measure helps maintain orderly trading conditions and limit excessive speculative activity.

During the ban period:

• No new F&O positions can be created.
• Traders may only reduce or square off existing positions.
• Violations may attract penalties from the exchange.

This mechanism supports market discipline, particularly during expiry weeks when volatility tends to rise.

About Nifty Weekly Expiry

Nifty 50 Futures & Options contracts typically expire every Tuesday. If the scheduled expiry coincides with a holiday, the expiry is shifted to the previous trading session. Contracts are settled based on the closing prices on expiry day.

On trading platforms, weekly contracts may sometimes appear under the 'monthly' section due to technical grouping, though this does not affect contract terms.
