Tencent is trading at 8X forward revenue
Qihoo is growing 2X that of Tencent.
If QIHU traded at 8X forward revenue = 13.6 billion valuation = 120 stock price
your math appears off. QIHU is trading at over 16x trailing revenue. they aren't projected to double their revenue going forward are they? IF they project doubling revenue, = 8x forward revenue, or a 90 stock price. IF revenues double.....
