The Langfang Development Co., Ltd. (SHSE:600149) share price has fared very poorly over the last month, falling by a substantial 31%. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 41% share price drop.

Although its price has dipped substantially, you could still be forgiven for thinking Langfang Development is a stock to steer clear of with a price-to-sales ratios (or "P/S") of 7.1x, considering almost half the companies in China's Trade Distributors industry have P/S ratios below 0.6x. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

How Langfang Development Has Been Performing

As an illustration, revenue has deteriorated at Langfang Development over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Revenue Growth Forecasted For Langfang Development?

Langfang Development's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better 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 11%. That put a dampener on the good run it was having over the longer-term as its three-year revenue growth is still a noteworthy 13% in total. So we can start by confirming that the company has generally done a good job of growing revenue over that time, even though it had some hiccups along the way.

Comparing that to the industry, which is predicted to deliver 17% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

With this information, we find it concerning that Langfang Development is trading at a P/S higher than the industry. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

Even after such a strong price drop, Langfang Development's P/S still exceeds the industry median significantly. 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.

The fact that Langfang Development currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
