老姚, I think my OIH short, POT short, still is a good trade.
I just start to short PCLN 2 days ago, I think this is a good trade. http://www.hutong9.net/home.php? ... o=blog&id=34607
BTW, ALKS, aug option volume is huge compare to any other months, and it's keep going up at average rate of 3% every day for the last few days. I bet some "insider" must knows something, may be a buy-out, take a look for yourself ok.
