I agree with you. If this is true. How would you feel if you are one of these options holder and failed to convert the option on time..due to some...reason. They got them at "no cost ?" and make a handful of profit instantly...Anyway, would they convert these options if the SP was just below the option execise price.This is a very rare incedence, the SP moved above the option exercise pricefew days before the expiry date ... Some option holder might not realise it..Is it legitimate ? Can someone help ?
