MUMBAI: The Bombay Stock Exchange (BSE) has made certain changes in the settlement period of index-based monthly futures and options (F&O) as well as all weekly options contracts, a move that will improve liquidity in the derivatives segment.
“It has been decided to change the expiry of all monthly index futures and options from last Thursday of the
month to the third last Thursday of each contract month.
“Further, expiry date of all weekly options contracts currently available for trading will also be changed to cycle of Friday-Thursday from cycle of Monday-Friday, that is expiry on Thursday instead of Friday,” the bourse said in a statement.
This change would take effect for all contracts starting from November 20, 2009. The bourse added, “Wherever the expiry of a weekly option contract coincides with the expiry of a monthly option contract, the respective weekly option contract would not be available, as the remainder expiry time of the monthly contract would make it akin to a weekly contract.”
