The Gain Plus Holdings Limited (HKG:9900) share price has done very well over the last month, posting an excellent gain of 296%. The last 30 days were the cherry on top of the stock's 603% gain in the last year, which is nothing short of spectacular.

After such a large jump in price, given close to half the companies operating in Hong Kong's Construction industry have price-to-sales ratios (or "P/S") below 0.3x, you may consider Gain Plus Holdings as a stock to potentially avoid with its 2.2x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Has Gain Plus Holdings Performed Recently?

Gain Plus Holdings has been doing a good job lately as it's been growing revenue at a solid pace. It might be that many expect the respectable revenue performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

We don't have analyst forecasts, but you can see how recent trends are setting up the company for the future by checking out our free report on Gain Plus Holdings' earnings, revenue and cash flow.

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

In order to justify its P/S ratio, Gain Plus Holdings would need to produce impressive growth in excess of the industry.

If we review the last year of revenue growth, the company posted a terrific increase of 19%. The latest three year period has also seen a 22% overall rise in revenue, aided extensively by its short-term performance. Therefore, it's fair to say the revenue growth recently has been respectable for the company.

It's interesting to note that the rest of the industry is similarly expected to grow by 8.8% over the next year, which is fairly even with the company's recent medium-term annualised growth rates.

With this information, we find it interesting that Gain Plus Holdings is trading at a high P/S compared to the industry. It seems most investors are ignoring the fairly average recent growth rates and are willing to pay up for exposure to the stock. Nevertheless, they may be setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

What Does Gain Plus Holdings' P/S Mean For Investors?

The large bounce in Gain Plus Holdings' shares has lifted the company's P/S handsomely. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Gain Plus Holdings revealed its three-year revenue trends aren't impacting its high P/S as much as we would have predicted, given they look similar to current industry expectations. Right now we are uncomfortable with the high P/S as this revenue performance isn't likely to support such positive sentiment for long. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
