On CAPS, 58% of the 147 members who have rated Qihoo 360 in believe the stock will underperform the S&P 500 going forward. These bears include All-Stars tad40 and BuffettJunior1, both of whom are ranked in the top 5% of our community.

Earlier this month, tad40 followed the lead of stock whistleblower Citron Research and warned Fools about Qihoo:

Leaning toward this being another Chinese fraud. "Citron" research has developed a tremendous volume of forensic research on Qihoo 360, and has concluded that the company has either not been forthright about their revenue model to Wall St., or there is a financial fraud unfolding.

Qihoo 360 even sports a rather lofty price-to-book multiple of 5.5. That represents a premium to other Chinese dot-com plays like (Nasdaq: SOHU) (2.0), Sina (Nasdaq: SINA) (3.3), and (NYSE: YOKU) (2.9).

CAPS All-Star BuffettJunior1 elaborates on the Qihoo 360 bear case:

I cannot believe I didn't come across this stock before. Even if the company wasn't a fraud, this valuation is truly astounding.

Why does this company have a 2 billion dollar market cap?

The company had $58 million in revenues last year, why on Gods all mighty earth would investors be willing to pay $2 billion for it? ...

I must be living in some kind of alternate reality where paying more than 100 times what something is worth is smart investing.

I just know one thing for sure. ... [T]he intelligent investor knows that common sense, above all else, is the most important thing in investing.
