I use Sharebuilder but I'm thinking about switching to USAA though.

HEB is a gamble, if they don't get FDA approval the stock will tank. If they do.. 300% return isn't far fetched. Look at VNDA on May 6th I believe.. went from $1 a share to $10 overnight just on approval alone. I'm not saying that is to be expected here but do look for nice gains.
