Will documentary whack SeaWorld stock?

A documentary named Blackfish exposes the dark side of holding killler whales captive to do tricks for SeaWorld audiences, says columnist Al Lewis of MarketWatch.

Lewis notes that the film premiered at the Sundance Film Festival in January, but went mainstream when it was shown on CNN October 24. CNN has used parts of it several times since then, and intends to use it more.

Lewis thinks SeaWorld stock will suffer. Actually, it hasn't yet. The stock was $29.76 on October 24 and closed at $30.76 on November 8. SeaWorld went public in early April.

I thought the stock offering stunk like a dead fish, because the proceeds would go to Wall Street firms and not to SeaWorld. Plus, I thought it was overpriced, compared with other theme parks. But the stock shot up from $27 to $34 before backing off to a price I still consider too high.
