Does VinFast Auto Look Pricey on Sales?

P/S is a useful check for VinFast Auto because the business is still loss making, so earnings based ratios like P/E are less informative. On this measure, VinFast Auto trades on a P/S of about 1.9x, which is higher than both the Auto industry average of roughly 0.6x and a peer group average near 0.9x.

The tailored fair P/S ratio for VinFast Auto is estimated at about 0.1x. The gap between this figure and the current 1.9x is very wide, and the model is heavily penalising the company for its losses, risk profile and the quality of its current revenue base. Rather than treating that fair ratio as a precise target, it may be more useful as a clear warning signal that the stock screens as richly priced on this sales based framework.

On the P/S multiple, VinFast Auto stock screens as overvalued even after allowing for its growth ambitions and sector context.
