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.

Still, that rollercoaster ride pales in comparison to that of Tesla 's (NASDAQ: TSLA) stock. Investors watched shares slide more than 50% from their high near the end of last year through April, before rebounding a whopping 62% and again falling nearly 20%.
