The stock exchange said the change in Nifty Bank monthly and quarterly contract cycle expiry day from existing Thursday to Wednesday will be effective from trade date March 01, 2024, Friday.
Market data shows that the share of retail participation in the cash segment (turnover) has declined while it has increased in index options (premium). Retail traders now contribute about 35% of the turnover in index options premium as compared to 22% in 2016.
Under the new rules, announced in July, Nifty Bank weekly index options will expire every Wednesday instead of Thursday from September 6. But for monthly and quarterly contracts of the widely-tracked banking index, there is no change and will continue to expire on the last Thursday of the expiry month.
