Ronglian Group Ltd.'s (SZSE:002642) price-to-sales (or "P/S") ratio of 1.8x might make it look like a buy right now compared to the IT industry in China, where around half of the companies have P/S ratios above 3.4x and even P/S above 7x are quite common. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

How Ronglian Group Has Been Performing

For instance, Ronglian Group's receding revenue in recent times would have to be some food for thought. It might be that many expect the disappointing revenue performance to continue or accelerate, which has repressed the P/S. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

How Is Ronglian Group's Revenue Growth Trending?

The only time you'd be truly comfortable seeing a P/S as low as Ronglian Group's is when the company's growth is on track to lag the industry.

Retrospectively, the last year delivered a frustrating 37% 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 32% 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 25% shows it's an unpleasant look.

With this in mind, we understand why Ronglian Group's P/S is lower than most of its industry peers. However, we think shrinking revenues are unlikely to lead to a stable P/S over the longer term, which could set up shareholders for future disappointment. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

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.

Our examination of Ronglian Group confirms that the company's shrinking revenue over the past medium-term is a key factor in its low price-to-sales ratio, given the industry is projected to grow. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. Given the current circumstances, it seems unlikely that the share price will experience any significant movement in either direction in the near future if recent medium-term revenue trends persist.
