Friend, the stock is higher than the price you sold at and it's going to go higher.
The technicals don't matter or how quickly it rebounds. EMC is in there buying again and they are going to continue buying up the shares.
As someone else mentioned, with EMC taking so many shares off the market, the amount in the tradable float is low. And that means more price volativility. As the wholesale selling/shorting subsides, it's just going to make the move back up that much more intense when it really kicks in.
With all of the new neophyte shorts jumping in after the fact, I expect that rebound you were looking for to come, it may just be a few weeks from now - maybe as the stock gets back to $85 and they are all scared off.
I may need to check into what 6 month and 12 month call options are trading at this morning.
