Just think about how much they gained during last year and how much their stock was appreciated. The ratio of gain in business (about 100% overall) to the increase in stock price (400%) will tell people whether it is the time to buy, hold or sell.
People always believe Qihu continues to eat Bidu's lunch, but this report did not show any significantly increased takeover from Bidu's dominated business. two months ago, Bidu's price was 170-185, today it was closed about 184, while Qihu was in the range of 66 to 91 and today it was closed about 121. Those are only all facts. But whether stock will rise, or stay or fell, the MM with huge funds in the control will decide the direction.
