Celsius shares jump as Rockstar founder raises stake, seeks CEO change

Celsius Holdings shares rose 10% on Friday after Rockstar Energy founder Russ Savage increased his stake and called for the CEO's replacement, CNBC reported. Savage told CNBC that Celsius management has lost credibility with investors and that he would be willing to lead the company as CEO. He holds more than 12 million shares, about 4.7 percent of the company. The push follows Celsius's Thursday quarterly results, which missed Wall Street estimates. Before the gain, the stock had fallen about 42 percent this year.
