You may be right... 10 cents and people are going crazy over the massive action.
It is massive in relative terms.
Meh...
Well, granted, the chart you linked makes this move look minute, but perhaps it was the necessary nudge to possibly ignite a rally.
In a market that used to see $.10 moves 10 times a day, then to have two solid weeks in a ten cent range, or the last month in about $.20 range, I don't think it's exactly overreaction to get excited. We're about to break the $5.07 resistance too. Maybe this was the kick in the ass people needed to act upon.
