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.
Indian equity markets bounced back with optimism ahead of the weekly expiry, but heightened F&O interest has led to a trading ban on 5 stocks on May 27. Traders should exercise caution as these restrictions could amplify volatility during expiry-driven moves.
