Most Chinese IPO's have done poorly in the aftermarket, not so with Qihoo ( QIHU). The tech company makes internet and mobile security products and is also positioning itself in the cloud. The company priced an offering of 12.1 million shares at $14.50 each on March 29, and the stock closed on Wednesday at $26.25, up 81%. Like LinkedIn, Qihoo had a phenomenal first day of trading, jumping 134% in its debut. By comparison, Baidu ( BIDU) rose 354% on its first day and Youku ( YOKU) was up 161% on its first trading day. Five analysts are now covering Qihoo with four rating it a buy. A positive catalyst on the horizon could be that Qihoo is about to hit the conference circuit.
