So you took your own advice and are a millionaire now?!?!
No, I was kidding when I gave that advice. The risk was far too great and no one could have reasonably anticipated that AIG would actually jump like it did.
Blankpage - let me clarify: penny stocks as a term generally refers to small cap illiquid stocks that trade OTC. Their relative illiquidity, the high probability of pump and dump schemes/insider trading, and general lack of transparency make them extremely risky investments. I wouldn't call SIRI a penny stock - even though it technically trades within that general price range - because it trades at very high volume with tight bid/ask, and is a large well followed company. As for your personal strategy, I personally believe that SIRI has an unacceptable risk vs. potential return, but aside from that I have no way of knowing whether you are extremely talented, plain lucky, or some other mixture of the two.
