When you see that almost half of the companies in the Tech industry in China have price-to-sales ratios (or "P/S") below 2.6x, Guangdong Green Precision Components Co., Ltd (SZSE:300968) looks to be giving off some sell signals with its 3.5x 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 Guangdong Green Precision Components' P/S Mean For Shareholders?

As an illustration, revenue has deteriorated at Guangdong Green Precision Components 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

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

Guangdong Green Precision Components' P/S ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 29%. The last three years don't look nice either as the company has shrunk revenue by 44% 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 19% shows it's an unpleasant look.

With this in mind, we find it worrying that Guangdong Green Precision Components' P/S exceeds that of its industry peers. 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

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.

We've established that Guangdong Green Precision Components currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. 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.
