Warrants... an instrument for those who have lost all respect for their money. They have a place as short-term hedge instruments IMO - and that is about it. I would far rather trade CFD's and manage my margin properly if I was inclined to take the risk.
i made monet for years off warrants, and the reason I don't trade them any mores is same reason I don't trade CFDs any more .. I don't trade shares at all .. trick with warrants is that if you get the trade right but pick the wrong one you lose, most pick teh wrong one
CFD's track "true" to the underlying share. Warrants are useless as soon as the price drifts more than a certain amount away from the strike - or if volatility picks up or... Iin no time at all - the warrant is so "out of the money" that you are left with a "stub" that represents an "interest packet" and nothing much more. So - the money that you put in is more at risk. A very professional instrument - that needs to be used mindfully as part of a portfolio. Trading then "naked" is a mug's game (or a genius's.)
