Sorry, KERX won't be able to do this. I'm long quite a few share in KERX, but they're just not that type of play. KERX is a buy and hold for an easy double when it gets bought out. Low risk, low gain (for a biotech). It's just a matter of when.
The company that can mimic or exceed PCYC in my humble opinion is INO. I'm long quite a few shares there too. Partnership deal and breakthrough status, which comprises PCYC's secret sauce, is imminent and very likely, respectively.
It appears that PCYC does not have any product in the market and it does not have any revenue, but it is trading at $108 per share with a whopping market cap of $8 Billion. Can somewhere explain why this is possible.
