Tesla and Detroit’s Automakers Price In a Trump Joyride. Good Luck.

Detroit voted overwhelmingly for Vice President Kamala Harris, but investors in “Detroit” backed President-elect Donald Trump. Shares in General Motors Co. and Ford Motor Co. jumped on news of Trump’s election win, with GM reaching a new high for the year and Ford up by almost 6% on Wednesday, more than double the S&P 500 Index’s gain. Meanwhile, in that other motor city, Austin, Tesla Inc. has added more than $100 billion to its already enormous market value.

The gains all look questionable, albeit for very different reasons when it comes to Elon Musk’s electric vehicle maker.

The positive take on a Trump presidency for Detroit’s incumbents revolves mostly around a relaxation of tailpipe emissions standards and tightening of EV incentives. The net result, on this reading, is that these companies get to sell more highly profitable trucks and SUVs with internal combustion engines and needn’t sell a rising number of loss-making EVs. Plus, Trump will maintain or increase tariffs on Chinese EVs and perhaps also raise tariffs broadly, hitting other foreign automakers (shares of Mercedes-Benz Group AG and Bayerische Motoren Werke AG were both hit Wednesday). Plus, of course, the corporate tax rate will fall and surging economic growth will boost sluggish car sales. Huzzah.

As with much that surrounds Trump, things may turn out to be a bit more complicated than that.

Say Trump tightens or, enabled by a Republican-controlled Congress, entirely rescinds the consumer tax credit for EVs, along with cleantech manufacturing credits established by President Joe Biden’s Inflation Reduction Act. This would actually deepen Detroit’s EV losses.

Think of Ford’s and GM’s EV businesses as startups, similar to Tesla in its first decade as a listed company. Their losses stem primarily from the fact that they are capitalizing the costs of investments in factories and machinery over too few vehicles sold. Automakers as a whole have invested $199 billion in EVs in the US over the past decade, according to Bloomberg Intelligence. GM boasted at its recent analyst day of EV losses having peaked this year and offering a $2 billion to $4 billion tailwind to operating profit next year, with half of that owed to expansion. In other words, what’s needed is to sell more EVs in order to reap economies of scale on existing investment. Sure, if they stop investing in EVs come January, then at some point down the line, the drag on returns is alleviated. In the meantime, it would be an earnings bloodbath of write-downs.
