Despite an already strong run, Valens Semiconductor Ltd. (NYSE:VLN) shares have been powering on, with a gain of 36% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 41% in the last year.

Although its price has surged higher, you could still be forgiven for feeling indifferent about Valens Semiconductor's P/S ratio of 4.9x, since the median price-to-sales (or "P/S") ratio for the Semiconductor industry in the United States is also close to 5.1x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

How Has Valens Semiconductor Performed Recently?

Valens Semiconductor hasn't been tracking well recently as its declining revenue compares poorly to other companies, which have seen some growth in their revenues on average. One possibility is that the P/S ratio is moderate because investors think this poor revenue performance will turn around. You'd really hope so, otherwise you're paying a relatively elevated price for a company with this sort of growth profile.

What Are Revenue Growth Metrics Telling Us About The P/S?

The only time you'd be comfortable seeing a P/S like Valens Semiconductor's is when the company's growth is tracking the industry closely.

Retrospectively, the last year delivered a frustrating 23% decrease to the company's top line. Regardless, revenue has managed to lift by a handy 30% in aggregate from three years ago, thanks to the earlier period of growth. So we can start by confirming that the company has generally done a good job of growing revenue over that time, even though it had some hiccups along the way.

Shifting to the future, estimates from the three analysts covering the company suggest revenue growth is heading into negative territory, declining 16% over the next year. With the industry predicted to deliver 40% growth, that's a disappointing outcome.

In light of this, it's somewhat alarming that Valens Semiconductor's P/S sits in line with the majority of other companies. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as these declining revenues are likely to weigh on the share price eventually.

What Does Valens Semiconductor's P/S Mean For Investors?

Valens Semiconductor's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our check of Valens Semiconductor's analyst forecasts revealed that its outlook for shrinking revenue isn't bringing down its P/S as much as we would have predicted. With this in mind, we don't feel the current P/S is justified as declining revenues are unlikely to support a more positive sentiment for long. If we consider the revenue outlook, the P/S seems to indicate that potential investors may be paying a premium for the stock.
