The NSE has changed the Bank Nifty Futures and Options expiry day to Friday from Thursday, effective from July 14. The move is seen as a response to competition from the BSE's Sensex and Bankex derivatives contracts, which expire on Friday and are attracting investors with lower charges.
PremiumIndia's largest derivative bourse, the National Stock Exchange of India (NSE) on Tuesday announced a change in the Bank Nifty Futures and Options (F&O) expiry day to Friday from Thursday with effect from July 14.
