Morgan Stanley analyst Andrew Percoco is becoming more constructive on Tesla ahead of its Q3 earnings, citing improving execution in Robotaxi and the core automotive business. Percoco described Tesla's Roadster as a showcase of engineering prowess, highlighting its technological crossover with SpaceX, but cautioned that the commercial potential of a flying Roadster remains uncertain. The firm sees the Roadster primarily as a demonstration of Tesla's technological capabilities, rather than a near-term sales driver.
