Tesson Holdings Limited (HKG:1201) shares have continued their recent momentum with a 27% gain in the last month alone. Unfortunately, despite the strong performance over the last month, the full year gain of 7.2% isn't as attractive.

Following the firm bounce in price, when almost half of the companies in Hong Kong's Electrical industry have price-to-sales ratios (or "P/S") below 0.5x, you may consider Tesson Holdings as a stock probably not worth researching with its 2.3x 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.

What Does Tesson Holdings' Recent Performance Look Like?

As an illustration, revenue has deteriorated at Tesson Holdings over the last year, which is not ideal at all. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

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

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 15%. The last three years don't look nice either as the company has shrunk revenue by 78% 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 29% shows it's an unpleasant look.

With this information, we find it concerning that Tesson Holdings is trading at a P/S higher than the industry. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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.

The Final Word

The large bounce in Tesson 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 Tesson 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. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. 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.
