On CAPS, 97% of the 1,265 members who have rated ViroPharma believe the stock will outperform the S&P 500 going forward. These bulls include fellow Fool Rich Smith (TMFDitty) and zzlangerhans, both of whom are ranked in the top 1% of our community.

Late last year, Rich tapped ViroPharma as a particularly potent opportunity: "Projected growth is upwards of 15%, and I don't see the risk of hospital infections going away any time soon. Looks like a strong, long term growth/value candidate to me."

Over the past three years, in fact, ViroPharma has grown its top line at a brisk rate of 32%. That's faster than listed competitors AstraZeneca (2.9%), Gilead (20.4%), and Salix (23.8%).

CAPS All-Star and biotech expert zzlangerhans elaborated on the bull case just a couple of weeks ago:

I've been keeping Viropharm at arm's length for quite a while, expecting news of a Vancocin generic to cleave the share price in twain at any moment. In the meantime, the company's genius 2008 acquisition Cinryze has shown steady growth with no sign of maturity. ...

Lately the share price has shown signs of slacking momentum, falling off highs in the low 20's seen in April. Perhaps continuing legal setbacks in their fight against generic Vancocin, or the recent approval of Optimer's fidaxomicin, are finally taking their toll on investor optimism. But Cinryze has received a favorable opinion from CHMP and European sales may begin before the end of the year. The company has been buying back shares, and non-toxigenic c.diff strain VP20621 recently kicked off a phase II study to prevent c.diff recurrence.
