Buffett just messed things up for Teva short-sellers

IT'S not like there was any real risk in shorting an easy target like Teva Pharmaceutical Industries. Warren Buffett could come along to destroy your bet, but what were the odds of that happening?

Oops.

It's not a happy Valentine's Day for Teva short-sellers. After the market closed Wednesday, a filing from Buffett's Berkshire Hathaway disclosed that it made only one new investment during the latest quarter. Unluckily for Teva bears, it was the Israeli generic-drug maker they've been betting against to the tune of US$1.2 billion.
