Cut off date is 04/08/2014(Monday) then last trading day should be day before trading day..
So 2nd and 3rd are Saturday and Sunday so must be last trading day is Friday 1st of August 2014.
you can keep it up to payment day 24/08/2014...it is day before expiry day (25/08/2014) ..
but you need to pay the exercise price 118/= otherwise you will get nothing..
even if you have 1000 W13 then you need to pay 118 000/= ...
if any one keep 100 000 then 11 800 000/= need to pay ..
easy to buy 100 000 W13 with 50 000/= but we can't pay 11 800 000/= ..So very care full if you want to keep those.. end of the day you will get nothing..
So if you are not that much of rich sell all before end of next week ... Don't get panic.. watch carefully the situation about CLPL then think about where you need to exit.
Note: I talk too much about W13 .. but still I have some .. I will sell before end of next week. but I believe next week for CLPL ... So I will sell with good profit. then play with W6
