Brainhole Technology Limited (HKG:2203) shareholders would be excited to see that the share price has had a great month, posting a 93% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 20% in the last twelve months.

In spite of the firm bounce in price, when close to half the companies operating in Hong Kong's Semiconductor industry have price-to-sales ratios (or "P/S") above 1.5x, you may still consider Brainhole Technology as an enticing stock to check out with its 0.4x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

What Does Brainhole Technology's Recent Performance Look Like?

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 low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Do Revenue Forecasts Match The Low P/S Ratio?

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

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 16%. The last three years don't look nice either as the company has shrunk revenue by 16% 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 10% shows it's an unpleasant look.

With this in mind, we understand why Brainhole Technology's P/S is lower than most of its industry peers. Nonetheless, there's no guarantee the P/S has reached a floor yet with revenue going in reverse. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

The Final Word

The latest share price surge wasn't enough to lift Brainhole Technology's P/S close to the industry median. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Brainhole Technology revealed its shrinking revenue over the medium-term is contributing to its low P/S, given the industry is set to grow. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. Given the current circumstances, it seems unlikely that the share price will experience any significant movement in either direction in the near future if recent medium-term revenue trends persist.
