StarGlory Holdings Company Limited (HKG:8213) shareholders have had their patience rewarded with a 26% share price jump in the last month. The last 30 days bring the annual gain to a very sharp 33%.

Since its price has surged higher, when almost half of the companies in Hong Kong's Hospitality industry have price-to-sales ratios (or "P/S") below 0.8x, you may consider StarGlory Holdings as a stock probably not worth researching with its 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 StarGlory Holdings Has Been Performing

For example, consider that StarGlory Holdings' financial performance has been poor lately as its revenue has been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

Do Revenue Forecasts Match The High P/S Ratio?

The only time you'd be truly comfortable seeing a P/S as high as StarGlory Holdings' is when the company's growth is on track to outshine the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 14%. This means it has also seen a slide in revenue over the longer-term as revenue is down 22% in total over the last three years. 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 information, we find it concerning that StarGlory Holdings is trading at a P/S higher than the industry. 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 heavily on the share price eventually.

What We Can Learn From StarGlory Holdings' P/S?

The large bounce in StarGlory Holdings' shares has lifted the company's P/S handsomely. 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 examination of StarGlory Holdings revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
