lol dude literally got lucky timing shit and he chalked it up to trading well. 
  
 the minute he thinks he's unstoppable and overextends is when the shit show starts. 
  
 can EA return to $150? sure why not - it was there before. anyways he has the luxury of buying shares so he should be fine.

He invests in low float stocks on purpose. Easier to manipulate/pump.
