On CAPS, 33% of the 66 All-Star members who have rated Sinovac believe the stock will underperform the S&P 500 going forward.

Earlier today, one of those Fools, zzlangerhans, succinctly summed up the bear case for our community:

Sinovac is now back in unsustainable territory due to the double whammy of a new bird flu epidemic and positive results for the EV71 vaccine for hand-foot-mouth disease. As always, the flu scare will resolve itself without any contribution from Sinovac or any long-term impact on their revenues. And EV71 is no doubt benefiting from public confusion over hand-foot-mouth disease, a benign illness of children that sounds a lot like hoof-and-mouth disease, an economically disastrous disease of cattle. Not every childhood viral illness requires a vaccine. I suspect that even though a few hundred children die of hand-foot-mouth out the million who contract it every year in China, the Chinese government won't see it as a public health issue pressing enough to require a new vaccination program. Eventually, Sinovac will have to live or die based on their hepatitis vaccine programs which of late have looked somewhat stagnant.
