I don't trust their upgrades though.
Look at TSLA!
I made a ton of $ going against their downgrade yesterday!
Here is the text I just received:
10-May-13 08:47 ET
SINA upgraded to Buy from Neutral at Goldman (57.54 )
Sentiment: Strong Buy
Goldman upgraded FB to $38.00. Than what? Look at the price.
An EV/EBITDA of 144? I'll pass.
