When close to half the companies in the Leisure industry in China have price-to-sales ratios (or "P/S") below 3x, you may consider Guangzhou Pearl River Piano Group Co.,Ltd (SZSE:002678) as a stock to avoid entirely with its 6.2x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Guangzhou Pearl River Piano GroupLtd's Recent Performance Look Like?

For example, consider that Guangzhou Pearl River Piano GroupLtd's financial performance has been poor lately as its revenue has been in decline. 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.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Guangzhou Pearl River Piano GroupLtd would need to produce outstanding growth that's well in excess of the industry.

Retrospectively, the last year delivered a frustrating 38% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 52% 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.

In contrast to the company, the rest of the industry is expected to grow by 25% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's alarming that Guangzhou Pearl River Piano GroupLtd's P/S sits above the majority of other companies. 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Final Word

Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our examination of Guangzhou Pearl River Piano GroupLtd 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.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Guangzhou Pearl River Piano GroupLtd, and understanding should be part of your investment process.
