dear fyers,
as i knowledge about bonuses if bonus change the actual equity quantity of xyz share.so43, who buy futures of that xyz share then he will also recieve bonus by change in the lot size but contract value remain same.
note:- Bonus is declared out of reserve, that is free reserve will converted into capital, hence the price goes down with equivalent rise in no of open shares. So it is no profit no loss situations on ex date of bonus dividend
