What about Options (SVLOB)?, page-11

You buy the option for .068 and have to pay the strike price (0.06) to convert it to a share on or before the option expiry date. You'll normally play a premium for the option depending on how long it has to go before expiry. The longer the time period before expiry the bigger the premium. The option gives you better leverage to a rising share price if SVL went to $0.18 (50% increase), the option should go to $0.12 (100% increase). But if SVL shares went to $0.09 (25% drop) the options would go to $0.03 (50% drop). You occasionally hear people referring to the share as "Heads" and options "Tails". I sure the tails aren't your thing so avoid them, or at least for another week or 2 until I've finished accumulating.
