SEBI allots F&O expiry days, NSE gets Tuesday, and it is Thursday for BSE

National Stock Exchange (NSE) has received capital market regulator SEBI’s nod for Tuesday as its expiry day, according to a company filing on June 16. BSE has confirmed that its expiry day proposal for Thursday has been accepted.

The communication from the regulator has been conveyed to both the exchanges.

BSE and NSE have said in their communication that for existing contracts, they intend to keep the expiry day unchanged for already-introduced contracts, with the exception of long-dated index options contracts, which will be suitably realigned to expiry day. Derivatives contracts which expire on or before August 31, 2025, will continue with the present expiry day, while contracts of BSE and NSE that are to expire after September 1, 2025, will see their expiry day change to Thursday and Tuesday, respectively.

Metropolitan Stock Exchange too has received Tuesday as its expiry day, whenever it decides to launch its derivative expiry contracts.

Rohit Srivastav, the founder and market strategist of Indiacharts.com has said: “When there is an options expiry on a Tuesday, two things happen from the perspective of an options buyer. The weekend becomes an unfavourable period to hold an option due to time decay. So, most buyers are unlikely to hold their positions until expiry – they typically square off by Friday.” He is also of the view that Thursday expiry is more favourable for positional traders. They can hold positions over a few days without worrying about weekend time decay.
