The gist
Tesla stock fell 6% on Sept 4 after Cybercab launch and NHTSA probe.
The drop shows investor doubts about Tesla's robotaxi future and valuation.
Background
Tesla's stock had been on a hot streak in August, climbing 18%, as optimism grew about its AI and autonomous driving efforts. However, the much-hyped Cybercab launch event on Sept 3 failed to impress investors, and federal regulators opened an audit query into the vehicle's safety certification. This led to a 6% drop on Sept 4, adding to Tesla's struggles this year, with the stock down over 20% in 2026.
