What Actually Moves TSLA Stock?
What moves Tesla’s stock price? It’s a good question because, even though Tesla is one of the most talked-about and followed stocks on the market, the answer isn’t always clear. Tesla misses margin expectations in its electric vehicle (EV) business, and the stock sells off, leading investors to conclude that Tesla is really just a car company. Management announces a ramp in capital expenditures, and the market concludes it’s all about cash flow now. So, what exactly drives Tesla stock? Here’s my honest take.
The usual answer
As boring, dry, and analytical as it might sound, it boils down to a discounted cash flow (DCF) analysis for the stock. However, as anyone who has ever done a DCF in earnest will tell you, the end product is a slave to relatively small fluctuations in the inputs. Tweak the cost of capital here, or nudge an assumption over cash flow margins there, and the valuation can be wildly different each time. Moreover, the volatility in share prices simply doesn’t reflect investors making minute adjustments to DCF valuations based on news flow here or there.
Rather than being pushed around by Wall Street analysts updating DCF spreadsheets, the reality is Tesla stock moves on the market’s perceptions of the changes in the inputs, and the highest impact input right now is:
- The likelihood and timing of earnings and cash flow from robotaxi
Perceptions matter
I’m not the biggest fan of Cathie Wood’s ARK Invest, but there’s a reason its valuation model assigns 88% of the stock’s enterprise value to robotaxis and just 9% to EVs in 2029. Digging into the Wall Street analyst consensus from Visible Alpha reveals that analysts expect robotaxi revenue to scale dramatically and hit $155.5 billion in 2032; the first year it will surpass expected automotive revenue of close to $138 billion. Given the much higher profit margins and recurring revenue from the
robotaxi business, it’s understandable that this will be the key to Tesla’s future cash flow.
Unfortunately, perceptions around that cash flow and its timing have been shifted by various factors this year.
Where are the robotaxis/Cybercabs?
The decline in the stock price this year is almost certainly due to a pushout in expectations for robotaxis, and that’s largely because the rollout hasn’t matched the kind of pronouncements CEO Elon Musk previously made about it.
No, the robotaxi fleet didn’t cover half the U.S. population by the end of 2025. No, robotaxi services weren’t expanded to 8-10 cities by the end of 2025, and the robotaxi fleet hasn’t doubled every month in 2026. All of these expectations were based on pronouncements made by Musk, and as every investor knows, as soon as they are made, Wall Street and investors start penciling in revenue and cash flow assumptions that bake them in. Remember what I said about the importance of inputs into DCFs?
Ultimately, the failure to meet these expectations has led to the stock being punished in 2026. It gets worse. By couching expectations in terms of robotaxi fleet size and city deployments, Musk influenced investors to closely monitor these metrics. Of course, it doesn’t hurt that they are easily and lovingly monitored on social media. Every failure to add X or Y robotaxis or cities is met with wailing, gnashing of teeth, and the woeful conclusion that the rollout is failing.
A reset to robotaxi expectations
The good news is that Tesla’s management has now shifted the narrative around the stock from fleet/cities to validating and releasing the version of full self-driving (FSD) that it believes will enable large-scale robotaxi deployment, namely v15. Consequently, the market’s perceptions should be reset to monitoring progress on v15 and growing robotaxi miles under the evolving v15 FSD.
Head of AI, Ashok Elluswamy, confirmed that the robotaxi fleet is already using early versions of v15 on the recent earnings call, and “we had planned roughly about seven major improvement tracks, and they’re all happening in parallel. The early v15 builds that are running on robotaxi have already — 40% of those tracks merged together, and that’s what’s running in the fleet right now.”
This narrative was repeated by a JPMorgan analyst recently and has now become the key marker the market is following.
The bullish case for Tesla stock
The stock will move on robotaxi news, and the good part is that expectations should now have been reset after Musk’s previously overly optimistic pronouncements. Cybercabs will launch in early September; the incident data reported to the National Highway Traffic Safety Administration (NHTSA) remains highly impressive, and hopefully v15 will resolve the various edge cases and pickup/drop-off issues that robotaxi users have reported. This is what will move Tesla stock.
