China Automotive Interior Decoration Holdings Limited (HKG:48) shares have had a horrible month, losing 59% after a relatively good period beforehand. Looking at the bigger picture, even after this poor month the stock is up 74% in the last year.

In spite of the heavy fall in price, it's still not a stretch to say that China Automotive Interior Decoration Holdings' price-to-sales (or "P/S") ratio of 0.3x right now seems quite "middle-of-the-road" compared to the Auto Components industry in Hong Kong, where the median P/S ratio is around 0.4x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

What Does China Automotive Interior Decoration Holdings' Recent Performance Look Like?

For example, consider that China Automotive Interior Decoration Holdings' financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

How Is China Automotive Interior Decoration Holdings' Revenue Growth Trending?

China Automotive Interior Decoration Holdings' P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with 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 41%. This means it has also seen a slide in revenue over the longer-term as revenue is down 38% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 18% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's somewhat alarming that China Automotive Interior Decoration Holdings' P/S sits in line with the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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

Following China Automotive Interior Decoration Holdings' share price tumble, its P/S is just clinging on to the industry median P/S. 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.

Our look at China Automotive Interior Decoration Holdings revealed its shrinking revenues over the medium-term haven't impacted the P/S as much as we anticipated, given the industry is set 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. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
