Hatem Dhiab attributes today's Tesla (TSLA) earnings report as a "day of reckoning" for the EV maker. He still believes Tesla is a car company at its core, expecting a 13% drop in year-over-year deliveries to paint a nasty profit picture. Hatem says Elon Musk needs to take steps away from D.C. and back into his CEO role. He says Tesla "is a growth company that has not grown" that needs signs of turnaround in today's report.
