Currently the May $18 call (expires April 26th) is trading around .091 (last trade) so it would cost you $455 to buy today. (btw it was substantially cheaper yesterday)
Because it is an option purchase this is the limit of your risk.

Lets track this trade and see where it goes over the next few months.

If the market does not break out in a couple months I will add another position, we will wait for six months or so and tabulate our loss or gain.
