Catone is looking for growth to justify Tesla’s triple-digit P/E ratio, and he does not see it. While the investor acknowledges that energy generation and storage revenues are rising, these segments still play a relatively small role (21%) in the company’s overall revenues.

Tesla stock opened up 5.5% at $410.50 before slipping. The initial rise was a surprise for two reasons. For starters, earnings were relatively weak and guidance was “vague,” according to Morgan Stanley analyst Adam Jonas.
