On CAPS, 17% of the 168 members who have rated Opko believe the stock will underperform the S&P 500 going forward.

Just last week, one of those bears, All-Star TMFBlacknGold, touched on Opko's seemingly unsustainable valuation:

I see a lot of speculation here about a buyout, but let's get back to reality. It doesn't seem likely that any company will pay over $2 billion for just $170 million in net assets and less than $40 million in annual revenue. Opko goes from a measly $5-$6 million in quarterly revenue to $11 and all of a sudden it's the best company ever? Look closer and you'll see that a near doubling in revenue resulted in an even larger loss than last year!
