Tesla (NASDAQ:TSLA) inventory has been hammered in current weeks. On 21 January, the day after the US President Trump’s inauguration, Tesla inventory was buying and selling for $424. On the time of writing, the inventory is at $258. This implies the inventory is down 39% over the six-week interval. As such, a £10,000 funding then can be price simply £6,100 now. In truth, given the appreciation of the pound over the interval, the forex-adjusted determine can be nearer to £5,700. It goes with out saying, however this may be a really disappointing funding consequence.

So, why has it occurred?

Tesla boss Elon Musk has a place throughout the new administration and seemingly the power to exert affect authorities coverage. This may increasingly have buoyed some retail traders following Trump’s election, however the pleasure is fading. And there are extra components at play.

Deteriorating fundamentals paint a worrying image

The most recent figures present Tesla’s fundamentals are deteriorating. Analysts have drastically lower 2025’s earnings per share forecast to simply $2.85, which is a staggering 66% decrease than estimates from two years in the past and 12% beneath mid-January projections. Income estimates have been revised down by $4.3bn to $112bn.

Including to investor considerations, three Tesla insiders — together with Elon’s brother Kimbal — have deliberate important inventory gross sales for 2025 price roughly $300m. These deliberate gross sales, whereas scheduled prematurely, are certain to hurt investor confidence.

Valuation stays stratospheric regardless of decline

Regardless of the current pullback, Tesla’s valuation metrics stay eye-popping. The present price-to-earnings (P/E) ratio stands at 108 instances, primarily based on trailing 12-months earnings of $2.23 per share. Whereas this represents a 21% low cost to Tesla’s five-year historic common P/E of 138 instances, it’s nonetheless dramatically greater than opponents and different tech giants.

In the meantime, Tesla’s P/E-to-growth ratio, which measures price relative to earnings progress, sits at 6.6 —considerably higher than it was a few months in the past, however nonetheless vastly elevated in comparison with conventional automakers and different expertise and even AI firms.

Margin compression threatens progress story

Tesla’s working margin has contracted alarmingly — from a peak of 16.8% in 2022 to simply 7.2% in 2024, with This autumn’s margin falling to six.2%. This margin erosion displays intense pricing stress and the corporate’s battle to keep up profitability whereas pursuing affordability. The automotive gross revenue scenario is especially regarding. In This autumn 2024, Tesla generated $3.29bn in automotive gross revenue, lower than it produced in Q3 2021 ($3.67bn) with half the deliveries. This dramatic effectivity decline explains why Tesla’s earnings energy has weakened regardless of elevated deliveries.

The decision: proceed with excessive warning

Tesla stays a polarising funding. Bulls level to imminent initiatives just like the Robotaxi pilot in Austin this June, whereas bears spotlight the corporate’s valuation disconnect, declining margins, and administration’s tempering of progress expectations.

Although Musk has referred to as 2025 Tesla’s “most pivotal year,” the realities of slowing progress and intensifying competitors recommend traders ought to strategy with excessive warning. What’s extra, with Musk distracted by DOGE and SpaceX, amongst different issues, Tesla’s AI future (Robotaxis and robotics) isn’t being bought in addition to it has been.

Regardless of my private appreciation for Tesla as a model, at present ranges, the inventory’s dangers merely outweigh the potential rewards. I cannot be including the shares to my portfolio.
