I am not projecting a pop per se. My point was simply that there is incentive, from a tax standpoint, to delay taking a profit in AVXL until next week. That applies if you are short from 12 or long from 3.
That said, if tax factors were the only factors, I would say AVXL would rise next week. There is incentive for longs to take tax losses now by selling and incentive for short to wait until next week to cover.
