At 9:30am, the stock opened at $26.70, went to $26.80 and back to $26.70 before slowly taking off and making big gains on the day reaching a high of $27.74. I-watch shows heavy buying all day long with again all institutional and non I-watch (most likely hedge funds) participants (25% and 75% respectively, 0% retail investors). Certainly makes for a good argument to not short Cramer recommendations where the institutional holders make up over 90% of the owned shares.
