Investors knew electric vehicle (EV) sales have been slumping for Tesla ( TSLA -8.44%). The EV leader announced a 13.5% year-over-year drop in second-quarter deliveries on July 2. Yet the stock is tanking today after Tesla reported its full second-quarter financial update today.

Tesla shares plunged as much as 10% in early trading Thursday as investors digested another dismal quarter of car sales – and CEO Elon Musk’s admission that slump may not end anytime soon.

Tesla stock falls more than 6% pre-market after Q2 earnings call. Sales decline, EV incentives end, and new Model Y trim disappoints.
