AMVS... a real winner, but for how long??

Gene said: "I bought a nice chunk of this company last saturday and came out yesterday with over 40% in profits! It went up 14% on last monday and 24% yesterday, not to mention some minor but consistent increases in between. I got out yesterday as it ended with very low volume but im thinking about investing a small percentage back into the stock as I believe, looking at past trends, that it will keep rising for another week or more. Waddaya think?"
