Tesla's share price has soared about 40% since the beginning of June, driven by better-than-expected second-quarter vehicle delivery results. This has caused a significant impact on hedge funds that had piled into short bets against the electric vehicle maker.

Tesla's profit margins are likely to improve due to lower production and raw material costs, according to Morningstar Inc.'s Seth Goldstein. The company is expected to return to profit growth next year. Additionally, Tesla's latest vehicle-sales results, published on July 2, revealed second-quarter deliveries figures that beat average analyst estimates, driving the company's shares to a six-month high.
