Noted short-seller Jim Chanos of Kynikos Associates continued to add to his short position in electric car maker Tesla throughout the year even as the company's shares rallied, he said at the Reuters Global Investment 2018 Outlook Summit on Tuesday.

Chanos, who first disclosed his short position in the company in May last year, said that he expected chief executive Elon Musk to step down from his position by 2020 to focus on his private rocketship company SpaceX as competitors such as BMW and Porsche expand their lines of luxury electric vehicles.
