A lot of Tesla's stock price is betting on the future potential of the company's initiatives outside of traditional EV sales. Most recently, Elon Musk claimed that robotics could help Tesla's market cap get to $30 trillion, making it by far the most valuable company in the world.

The bulk of Tesla's past stock performance has come from the growth of its EV division. Pioneering the industry, Tesla dominated new EV sales for a few years with its Model 3 and Y concepts, leading revenue to come close to $100 billion and operating income to soar past $10 billion. Now, these figures are all moving in the wrong direction.

Tesla would need to grow earnings at a very high rate over an extended span to justify its current stock multiple.
