The Brainhole Technology Limited (HKG:2203) share price has softened a substantial 28% over the previous 30 days, handing back much of the gains the stock has made lately. The good news is that in the last year, the stock has shone bright like a diamond, gaining 157%.

Although its price has dipped substantially, there still wouldn't be many who think Brainhole Technology's price-to-sales (or "P/S") ratio of 1.4x is worth a mention when it essentially matches the median P/S in Hong Kong's Semiconductor industry. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Brainhole Technology Has Been Performing

As an illustration, revenue has deteriorated at Brainhole Technology over the last year, which is not ideal at all. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

Is There Some Revenue Growth Forecasted For Brainhole Technology?

In order to justify its P/S ratio, Brainhole Technology would need to produce growth that's similar to the industry.

Retrospectively, the last year delivered a frustrating 27% decrease to the company's top line. The last three years don't look nice either as the company has shrunk revenue by 44% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 20% shows it's an unpleasant look.

With this in mind, we find it worrying that Brainhole Technology's P/S exceeds that of its industry peers. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

What Does Brainhole Technology's P/S Mean For Investors?

With its share price dropping off a cliff, the P/S for Brainhole Technology looks to be in line with the rest of the Semiconductor 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 look at Brainhole Technology revealed its shrinking revenues over the medium-term haven't impacted the P/S as much as we anticipated, given the industry is set to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
