There wouldn't be many who think Shijiazhuang ChangShan BeiMing Technology Co.,Ltd's (SZSE:000158) price-to-sales (or "P/S") ratio of 1.2x is worth a mention when the median P/S for the Luxury industry in China is similar at about 1.3x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

How Shijiazhuang ChangShan BeiMing TechnologyLtd Has Been Performing

For instance, Shijiazhuang ChangShan BeiMing TechnologyLtd's receding revenue in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

In order to justify its P/S ratio, Shijiazhuang ChangShan BeiMing TechnologyLtd would need to produce growth that's similar to the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 4.6%. This means it has also seen a slide in revenue over the longer-term as revenue is down 15% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 16% shows it's an unpleasant look.

With this in mind, we find it worrying that Shijiazhuang ChangShan BeiMing TechnologyLtd's P/S exceeds that of its industry peers. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a 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.

What We Can Learn From Shijiazhuang ChangShan BeiMing TechnologyLtd's P/S?

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.

We find it unexpected that Shijiazhuang ChangShan BeiMing TechnologyLtd trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
