Christopher Tsai retains faith in carmaker’s earnings potential despite backlash that has seen its shares take a hit

A devoted investor in Elon Musk’s Tesla – and once a close childhood friend of the US president’s eldest son and namesake – says he hopes the world’s richest man’s role in cutting federal spending for Donald Trump’s administration is “short-lived” and that he returns to managing his businesses.

Investment manager Christopher Tsai, whose firm has tens of millions of dollars tied up in Tesla, said the stock market had demonstrated clear signs of displeasure with Musk’s activities at the so-called department of government efficiency. And, in an interview with the Guardian, Tsai said: “I hope his involvement with [Doge] is short-lived so he can spend even more time on his businesses.”
