Bohai Water Industry Co.,Ltd (SZSE:000605) shares have had a horrible month, losing 28% after a relatively good period beforehand. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 23% in that time.

In spite of the heavy fall in price, Bohai Water IndustryLtd's price-to-sales (or "P/S") ratio of 1x might still make it look like a buy right now compared to the Water Utilities industry in China, where around half of the companies have P/S ratios above 2.2x and even P/S above 5x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Bohai Water IndustryLtd's P/S Mean For Shareholders?

For instance, Bohai Water IndustryLtd'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. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Is There Any Revenue Growth Forecasted For Bohai Water IndustryLtd?

Bohai Water IndustryLtd'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, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 1.0%. As a result, revenue from three years ago have also fallen 5.6% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 9.8% 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 understandable that Bohai Water IndustryLtd's P/S would sit below the majority of other companies. 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.

What We Can Learn From Bohai Water IndustryLtd's P/S?

The southerly movements of Bohai Water IndustryLtd's shares means its P/S is now sitting at a pretty low level. 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 Bohai Water IndustryLtd 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. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
