China Shipbuilding Industry Company Limited's (SHSE:601989) price-to-sales (or "P/S") ratio of 1.9x might make it look like a buy right now compared to the Machinery industry in China, where around half of the companies have P/S ratios above 3.2x and even P/S above 6x 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 Has China Shipbuilding Industry Performed Recently?

Revenue has risen firmly for China Shipbuilding Industry recently, which is pleasing to see. It might be that many expect the respectable revenue performance to degrade substantially, which has repressed the P/S. If that doesn't eventuate, then existing shareholders have reason to be optimistic about the future direction of the share price.

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

China Shipbuilding Industry's P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the industry.

Taking a look back first, we see that the company grew revenue by an impressive 19% last year. The latest three year period has also seen a 25% overall rise in revenue, aided extensively by its short-term performance. Therefore, it's fair to say the revenue growth recently has been respectable for the company.

This is in contrast to the rest of the industry, which is expected to grow by 30% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's understandable that China Shipbuilding Industry's P/S sits below the majority of other companies. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

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.

As we suspected, our examination of China Shipbuilding Industry revealed its three-year revenue trends are contributing to its low P/S, given they look worse than current industry expectations. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. If recent medium-term revenue trends continue, it's hard to see the share price experience a reversal of fortunes anytime soon.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with China Shipbuilding Industry, and understanding should be part of your investment process.
