really, you've shorted because of Bernstein? you must be kidding. Go look at the some 20+ other anal-ysts that have buys on VMW and $100+ price targets. btw, personally, i would not believe them either!
when Bernstein downgrades, that means he wants to buy at a lower price. once he is in, he will upgrade.
just look at Apple, they all had buys on it at $700. now they have sells. at $390 they were saying that it will go to $330. Apple reached $445 yesterday.
