Wall Street has already loaded up after scaring out retail with their previous scare tactics. Now they will walk up the price. Once the bull raid is done you will see loads of positive press, analyst upgrades, the already known positive trial results, etc. when they want to dump it onto the hands of less sophisticated retail and are done making the easy money.
Actually, it was not up $1.00 this week. On Monday it was down $0.19, then it was up the last four days as follows: $0.13, $0.31, $0.32, and $0.26. That gives a net change for the week of only $0.83. Still not bad at all, but lets not exaggerate...LOL
