Could indeed be shorts getting squeezed...love this management team for keeping those damn vultures off balance!
Might also be, assuming there is no leak of some positive s/p boosting news like a BP deal, that big money realizes 'IF' PT-125 is conclusively demonstrated, with further trials, to durably slow disease progression the M/C could easily climb to $3B. Now if it is demonstrated eventually, with optimum dosing, to halt or even roll back disease progression and significantly/durably improve cognition in a sig. percentage of recipients - well who knows where the M/C may end up; guess it all depends on just how effective and durable PT-125 turns out to be, but I like to think a M/C of at least $10B is achievable.
