Although the market's been on a tear over the last 12 months, few companies have been hotter than Qihoo 360 (NYSE:QIHU) -- and for good reason. The company, which began as an anti-virus software firm, has morphed itself into one of the most powerful Internet companies in all of China. In fact, over the last year, the company's done an impressive job leveraging its popular browser franchise as a means of attacking the lucrative search market. So, with this company making all the right moves, and its stock price rising accordingly, have investors missed out on the party? In this edition of our Ask a Fool series, Fool contributor Andrew Tonner breaks down Qihoo and gives his pick for the best buy in this space.
