Telsa (NASDAQ:TSLA) this week reported a dismal quarterly performance, but investors still rewarded the stock after top boss Elon Musk promised to return his focus to the company from his government advisory role and said the firm's robotaxi and artificial intelligence ambitions remained on track.

Elon Musk's time spent leading the Department of Government Efficiency (DOGE) will "drop significantly" starting in May, the Tesla boss announced during the company's first quarter earnings call on Tuesday afternoon.
