VinFast (VFS) Stock Still Looks Above Fair Value On 83% Fall

Simply Wall St · 2d ago

VinFast Auto stock has delivered heavy longer term losses for shareholders, yet the current market multiples suggest the shares still screen as expensive rather than a clear bargain. For investors looking at VinFast today, the core issue is how to weigh that weak track record against a low value score and an overvalued read on the broader checks.

  • Over the past 3 years, VinFast Auto has declined about 82.9%, which signals that long term investors have faced significant capital losses so far.
  • The valuation now rests heavily on how effectively VinFast can convert its electric vehicle ambitions into durable revenue and cash flow, while managing the risk that high capital needs and execution challenges keep pressure on profitability.
  • Across six separate checks, VinFast scores 0 out of 6 on value, which points to a stock that leans expensive on the broader framework rather than offering an obvious discount.

The issue now is whether VinFast Auto's current share price offers enough potential reward to justify those risks, given its recent valuation profile.

Has VinFast Auto Run Too Far on Sales?

The P/S multiple is often a useful way to look at VinFast Auto because the company is still building out its revenue base while reporting free cash flow losses. VinFast Auto currently trades on a P/S of about 1.9x, which is higher than both the Auto industry average of roughly 0.6x and the peer group average of about 0.9x. On simple comparisons, you are paying a richer sales multiple than many listed auto companies.

The fair P/S ratio generated by the model is about 0.1x. That figure is extremely low relative to the current 1.9x. The model is heavily penalising VinFast Auto for its recent losses, capital intensity and execution risks, so this output is better read as a warning that the stock screens very expensively on this framework rather than as a precise target level.

On the P/S multiple, VinFast Auto stock appears significantly overvalued relative to what this model suggests would be a more balanced sales-based valuation.

The Bottom Line

VinFast Auto still screens as overvalued on market multiples, with the P/S ratio sitting well above sector and peer levels and the model flagging an extreme gap between current pricing and what it treats as a more balanced sales multiple. That gap is largely driven by the company’s recent losses, capital needs and execution risks, which the framework penalises heavily. For you, the key question is whether VinFast Auto can translate its electric vehicle plans into sustained revenue and cash flow quickly enough to justify that richer multiple, or whether the current valuation is already pricing in more progress than the business has yet delivered.
