Wall Street is looking to Tesla's earnings for clues to Musk's plan to restore company's wild growth

Faced with falling global sales and a tumbling stock price, Tesla has slashed prices again on some of its electric vehicles and its “Full Self Driving” system. It's an apparent effort to boost the company's earnings growth. But Wall Street was unimpressed and will be looking for other answers from CEO Elon Musk when Tesla releases first-quarter earnings Tuesday. For Musk, the answer appears to be the long-elusive robotaxi, which he has been touting as a growth catalyst for Tesla. Now, Musk appears to be betting that the unveiling of a new robotaxi on Aug. 8 will be the catalyst that his company needs to return to huge annual sales growth.
