On CAPS, 56% of the 189 members who have rated Pharmasset believe the stock will underperform the S&P 500 going forward. These bears include All-Stars BuffettJunior1 and fellow Fool Sean Williams (TMFUltraLong), both of whom are ranked in the top 15% of our community.

Just last month, BuffettJunior1 touched on Pharmasset's seemingly unsustainable valuation:

This is truly one of the most overvalued stocks that I have ever seen. The company didn't even earn 1 million in revenue last year, and yet it has a market cap of 4.6 billion. The company has been losing an increasing amount of money every year since it has gone public.

In fact, Pharmasset currently sports an almost unbelievable price-to-sales multiple of over 4,700. That's obviously a massive premium compared to other pharmaceutical stocks like Merck (2.1), Vertex (34.1), and Pfizer (NYSE: PFE) (2.1).

Fellow Fool Sean Williams elaborates on the bear case:

It would literally take an act of God to justify Pharmasset's valuation at these levels. The company, if it can get any of its trials approved and onto market, is at minimum 2 years away from any revenue stream. Recent data released was positive, but the focus group literally could not have been any smaller. ... This is one of the goofiest valuations I've ever witnessed.
