"out of the money" you mean.. how does a warrant run out of money ?

anyway regardless of whether it's in the money or out, if you don't convert/redeem/exercise before the expiry date it will expire and become worthless.
Out of money means that the warrant is worthless to be converted eg.
mother share - RM0.50
warrant conversion price RM0.80
then the warrant is out of money since the mother share price is lower than the conversion price, better still buy directly the mother share.
The purpose of investing in warrant is to have high gearing (small knife cut big tree) eg.
Mother share RM10
Warrant conversion price RM5
Warrant current price RM6
Take the scenario of the share goes up tp RM15 and warrant follow suit to RM10
(15-10)/10 = 50% (the percentage gain from investing in the share)
(10-6)/6 = 66% (the percentage gain from investing in warrant)
Also you use less capital RM6 only compared to RM10 in share.
But if the share goes down below RM5 then the whole warrant become worthless and if expired at the time then you lose 100% of you RM6 capital but if you bought the mother share rather warrant at that time, you still can wait the market condition to improve and may be one day it will goes up to RM10 again. So the main enermy of the warrant is its expiry time.
