There wouldn't be many who think China Tianrui Automotive Interiors Co., LTD's (HKG:6162) price-to-sales (or "P/S") ratio of 0.7x is worth a mention when the median P/S for the Auto Components industry in Hong Kong is similar at about 0.5x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Has China Tianrui Automotive Interiors Performed Recently?

The recent revenue growth at China Tianrui Automotive Interiors would have to be considered satisfactory if not spectacular. It might be that many expect the respectable revenue performance to only match most other companies over the coming period, which has kept the P/S from rising. Those who are bullish on China Tianrui Automotive Interiors will be hoping that this isn't the case, so that they can pick up the stock at a lower valuation.

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

In order to justify its P/S ratio, China Tianrui Automotive Interiors would need to produce growth that's similar to the industry.

Taking a look back first, we see that the company managed to grow revenues by a handy 6.7% last year. Still, lamentably revenue has fallen 45% in aggregate from three years ago, which is disappointing. 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 18% shows it's an unpleasant look.

With this in mind, we find it worrying that China Tianrui Automotive Interiors' 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.

The Final Word

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.

We find it unexpected that China Tianrui Automotive Interiors 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. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
