Investors are betting Musk and Tesla will make a fortune under Trump even as threats mount

For Elon Musk fans, it’s the half-trillion dollar bet. The stock market value of Tesla has surged by that much since Donald Trump’s election, and kept climbing last week even as the electric car maker reported disappointed financial results for last year. The president has promised to cut regulations that Tesla says hobbles its ability to innovate. But Trump has also vowed to end federal subsidies for EV buyers among other plans that would hurt Tesla's profits. That includes launching a trade war with China, Canada and Mexico. But investors are betting that Trump does more to help Tesla than damage it in the long run.
