You are aware that analysts typically raise their price targets when their previous target is met right? Deutsche Bank set a $19 price target back in Nov '11. Good lord, it took 11 months to get to $19. You think that $30 figure is going to happen in a matter of days? That's not how it works.
A year from now, yes the stock should be at least $30, but not now. Pre-PDUFA high should be $20-21. After approval, we get a 25% bump from the 80% priced in approval pps, which gets us $25-$26 post-approval. Then, at 20% growth for the year, that's at $30-31. Coincidence? No. This stock is overbought. We shouldn't be at a level where we expect to be 2.5 months from now.
All of these figures assume a relatively non-restrictive approval that doesn't screw the 3k market potential estimates.
