I guess you have to include SINA in the list, that is considering that Goldman, then Deutsche -- those bastiens of veritas et lux-- then blah blah blah, all ganged up to push the price down going into earnings, but in spite of first dropping like a guillotine, it's had two big up days in a row now going into earnings on Tuesday. I hope those assholes bought all they wanted while it was down!
Whenever you read a downgrade based on "Gee Whiz, something bad (we are not exactly sure what) could happen in the future" you need to smell blatant price manipulation in the air. I haven't a clue what SINA will do Tuesday night, but it looks like Goldman and Deutsche think it will be good, based on their asinine downgrades.
Caveat emptor, as always.
