A Rough Time for Tesla

Last Monday, Tesla’s chief executive, Elon Musk, ran a demonstration of the company’s driverless cars and boldly claimed that he would have a fleet of autonomous taxis on the road next year. (Other experts say the vehicles are a few years from road readiness, at least.) Two days later, Tesla reported steep first-quarter losses, even worse than predicted. The company attributed the poor numbers to sluggish sales of its much-ballyhooed Model 3 sedan, which has suffered from production issues and lagging demand. But analysts saw it as yet another example of Mr. Musk’s tendency to overpromise and underdeliver.

Boeing Takes a Beating

Boeing’s troubled fleet of 737 Max jets has come home to roost, in the form of dismal quarterly numbers. The company’s stock slid last week after it posted its worst results in years, including a $1 billion hit to its commercial plane division. Boeing also didn’t provide its usual forecast for future sales and profits, as investigators are still trying to figure out what caused the two similar crashes of the 737 Max in the past year (and, more important, how to prevent them from happening again). Until then, a big chunk of Boeing’s business is out of commission.
