Houpu Clean Energy Group Co., Ltd.'s (SZSE:300471) price-to-sales (or "P/S") ratio of 5.3x may look like a poor investment opportunity when you consider close to half the companies in the Energy Services industry in China have P/S ratios below 2.1x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Houpu Clean Energy Group's Recent Performance Look Like?

For instance, Houpu Clean Energy Group's receding revenue in recent times would have to be some food for thought. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Revenue Growth Forecasted For Houpu Clean Energy Group?

Houpu Clean Energy Group'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.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 12%. At least revenue has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

This is in contrast to the rest of the industry, which is expected to grow by 21% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Houpu Clean Energy Group's P/S sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates 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 recent growth rates.

What Does Houpu Clean Energy Group's P/S Mean For Investors?

While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

Our examination of Houpu Clean Energy Group revealed its poor three-year revenue trends aren't detracting from the P/S as much as we though, given they look worse than current industry expectations. 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. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
