if you go long on bidu assume you will lose 10% off the bat. You simply can't time it. BUT the upside is 50%. So you come out way ahead. You got to hold the dips and can't panic.
Stock is up like 100 points in the last 3 months, Im sure if I buy at an even $300 it will fall straight to $250.
hahah I know nothing about this stock or company, but from a technicians viewpoint I would not buy this stock anytime in the near future. I would consider shorting it if I knew more about it. Thats my 0.0002
Go with the trend and use protective stops long. Don't try and guess the top. Wait for the trend to reverse and then short. That may be tomorrow or months from now.
