efr.wtairic i dont pretend to be an expert in the warrants arena but i buy them for the leverage.You dont have to put in as much cash to access future gains.To use efr as an example to buy 10k shares it would cost about 32k To buy 10k efr.wt it costs roughly 15k if efr ends up at 10 bucks one would 3x money from current price but the warrants would be trading around 7-8 bucks which would be about 5x down side is if efr tanks and doesnt recover before expiry date you lose your cash. Hoping this was helpful. mgm.wt also have attractive terms/price in my opinion glta
