The Brainhole Technology Limited (HKG:2203) share price has softened a substantial 44% 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 107%.

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 1.1x is worth a mention when the median P/S in Hong Kong's Semiconductor industry is similar at about 1.3x. 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.

What Does Brainhole Technology's Recent Performance Look Like?

For instance, Brainhole Technology's receding revenue in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The P/S Ratio?

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

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 27%. The last three years don't look nice either as the company has shrunk revenue by 44% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 19% 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. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Final Word

Following Brainhole Technology's share price tumble, its P/S is just clinging on to the industry median P/S. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

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. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
