In order to close my Penson account (can't have an US account while living in Canada), I had to sell my stocks (333 shares). I put a limit of 14.90 (sometime last week) and that's how I sold all of them today. It closed regular trading at 14.91. After hours and after the earnings call it traded at 4.60 down almost 70%!
Cool! I suppose it was the first time ever I was lucky with stocks... LOL
