See the impact of the "Oprah boost"

Not many people can move markets with a single tweet. Oprah Winfrey is one of them.

The TV star-turned-media mogul tweeted a video Tuesday in which she said she lost 26 pounds thanks to Weight Watchers. The weight loss firm’s stock skyrocketed, ending the day up 20% at $13.29 a share. (Things have since cooled slightly).

That was great news for Weight Watchers’ investors. Among those stockholders? Winfrey herself. She owns 6.4 million shares of the company, meaning she effectively tweeted her way to becoming $12.5 million richer in just a few hours.

As it turns out, Tuesday wasn’t the only time Weight Watchers has received the Oprah bump. The company’s stock, which was long stuck in the duldrums, shot up over 100% in October when it announced that Winfrey took a 10% stake. A second rise came a month later, when Weight Watchers said the media mogul would appear in a new series of commercials for the company. And once those commericals were out? You guessed it: Yet another boost.
