Dongjiang Environmental Company Limited's (HKG:895) 29% Share Price Surge Not Quite Adding Up

The Dongjiang Environmental Company Limited (HKG:895) share price has done very well over the last month, posting an excellent gain of 29%. Looking further back, the 19% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Although its price has surged higher, it's still not a stretch to say that Dongjiang Environmental's price-to-sales (or "P/S") ratio of 0.6x right now seems quite "middle-of-the-road" compared to the Commercial Services industry in Hong Kong, where the median P/S ratio is around 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 Dongjiang Environmental Performed Recently?

For instance, Dongjiang Environmental's receding revenue in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The P/S Ratio?

Dongjiang Environmental's 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 15%. This means it has also seen a slide in revenue over the longer-term as revenue is down 20% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 5.4% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that Dongjiang Environmental's P/S exceeds that of its industry peers. 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.

What We Can Learn From Dongjiang Environmental's P/S?

Dongjiang Environmental's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

We find it unexpected that Dongjiang Environmental 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.
