Tesla struggled through the first half of 2019, amid doubts over consumer demand and whether or not the company could achieve profitability. But the stock bounced back in the second half of the year, hitting a bevy of new all-time high share prices and reporting profits in both the third and fourth quarters. Earlier this year, Tesla became the first U.S. automaker to hit a $100 billion market cap. That’s now grown to $140.5 billion—almost twice the combined size of rival automakers General Motors ($48 billion) and Ford ($36 billion). Only Toyota has a higher market cap at this point.
