Leo Koguan is a third largest shareholder in Tesla (NASDAQ). As its stock price continues to fall, he urged Tesla (EV maker) to announce a $15Billion share repurchase plan.

Tesla should announce it will buy $5 billion of its shares this year and an additional $10 billion next year, Koguan said in a tweet to Martin Viecha, the carmaker’s senior director of investor relations. Koguan said that Tesla should fund the purchase using its cash flow.

To return capital shareholders receive, many companies regularly purchase back shares from the open market.

In his interview with Forbes in October, Koguan claimed he had made billions by investing in the electric carmaker and said he went “all in” on the company after he sold his holdings in Baidu (NASDAQ:), Nvidia (NASDAQ:), and Nio (NYSE:).

“I regarded myself as Elon’s fanboy,” Koguan reportedly said. “I would say he is the only person I really respect on Earth.”

Tesla’s shares dropped more than 6% Wednesday, following a larger market selloff. Year-to-date they are down more that 30%.
