Oprah not the only reason behind Weight Watchers' rally: CEO
Weight Watchers' CEO Mindy Grossman said Oprah Winfrey isn't the only reason for the company's rally, while pointing out improvements at the company. The company's stock on Friday jumped 25% to its highest closing price in four years after quarterly results. Winfrey, a long-time talk-show host, acquired 10% stake in the company in 2015, and also agreed to endorse it.
