Tesla stock tumbled about 9 per cent on Friday, wiping billions off the company’s value, after CEO Elon Musk confessed that the past year of his professional life has been “excruciating” and that stress over his business has caused his health to deteriorate.
In an emotional interview with The New York Times, the Tesla founder also revealed that the pressures of work had caused him to spend his birthday stuck in the Tesla factory and almost miss his brother’s wedding. “This past year has been the most difficult and painful year of my career,” he said, and warned that “the worst is yet to come”.
