No logic. All the biotechs are getting beat down today. Most are off by 5%. Only one showing any strength is a true penny stock, stem cell maker ISCO, up 2 cents, from 15 to 17 cents. They are making a presentation somewhere today.
My guess is that he's covering both bases with one move. If It moves up big he can point to the $48 pps and say that he was right on the direction of pps. If it stays in range he was right any way you look at it and if it crashes down he can point to the $36 pps and say that he was right on the direction. I've heard people in the forecasting business say "if you must forecast, do it frequently". This analyst is doing the next best thing probably because he can't do it frequently.
