Today’s Change

Current Price

Tesla (TSLA +5.50%), the global electric vehicle (EV) and energy storage manufacturer, closed at $367.95, up 5.51%. Investors focused on the upcoming Sept. 3 Cybercab event and renewed interest in FSD and robotaxi plans.

How the markets moved today

The S&P 500 (^GSPC -0.33%) closed at 7,686, down 0.33%, while the Nasdaq Composite (^IXIC -0.12%) closed at 26,371, down 0.12%. Among EV and automotive software peers, Rivian Automotive (RIVN -0.06%) closed at $16.06, down 0.06%, and Lucid Group (LCID -3.19%) closed at $4.85, down 3.19%.

What this means for investors

Tesla CEO Elon Musk has been guiding investors to focus on his company’s EV autonomy software as a main driver for Tesla’s future fortunes. The next big step in that regard is coming on Thursday, and anticipation looked to be helping drive shares higher today.

The invite-only Cybercab event in Austin is being billed as offering exclusive access to the steering-wheel- and pedal-free vehicle. Investors may hear more from that gathering about Tesla’s progress and plans for that brand-new product.

Tesla’s full self-driving (FSD) technology gained approval for a limited robotaxi rollout in Nevada two weeks ago, helping to expand its footprint and set the stage for an eventual Cybercab fleet.

Tesla stock will likely continue to trade on the success of that technology, as well as its robotics division. Investors shouldn’t get overly excited, though, until real progress is shown.
