The Clenergy Technology Co., Ltd. (SHSE:603628) share price has softened a substantial 35% over the previous 30 days, handing back much of the gains the stock has made lately. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 11% in that time.

Even after such a large drop in price, Clenergy Technology's price-to-earnings (or "P/E") ratio of 22.5x might still make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 27x and even P/E's above 48x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Clenergy Technology certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Is There Any Growth For Clenergy Technology?

The only time you'd be truly comfortable seeing a P/E as low as Clenergy Technology's is when the company's growth is on track to lag the market.

Retrospectively, the last year delivered an exceptional 178% gain to the company's bottom line. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

This is in contrast to the rest of the market, which is expected to grow by 41% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's understandable that Clenergy Technology's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

The Bottom Line On Clenergy Technology's P/E

The softening of Clenergy Technology's shares means its P/E is now sitting at a pretty low level. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of Clenergy Technology revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
