Heh, 500000 shares at the current price is $550 worth of stock - while it might seem small money, that's roughly the current position size on my plays due to money management guidelines I use.
After all I look for massive percentage returns ;-)
Funny thing is that my biggest hitter, $SRNW, made me a $2400 profit...out of a $180 bet ROFLMAOOOOOOO!!!! It was a Nevada Secretary of State reactivation play which I got in early and sold right at its peak.
