While "sell on the news" is certainly a possibilty especially with us small retail investors that have been burned in the past.
I believe that with only ~17% institutional ownership, they would rather buy @ $9 with the risk of unfavorable results out of the way, than buy at $7 with the risk of poor results still hanging out there. While those of us on this board and yahoo board may account for a million shares, that is pocket change for an institution. They would be more that happy to buy our shares for $9-10 in 4 weeks.
I've been hedging all along by selling out of the money puts and out of the money calls.
While I own many shares as well as Jan 2014 and 2015 calls, I started nibbling at August 23 calls as I expect the results to be out right before that expiration.
