Zhejiang Runyang New Material Technology Co., Ltd. (SZSE:300920) shareholders have had their patience rewarded with a 28% share price jump in the last month. Longer-term shareholders would be thankful for the recovery in the share price since it's now virtually flat for the year after the recent bounce.

Even after such a large jump in price, Zhejiang Runyang New Material Technology may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 28.2x, since almost half of all companies in China have P/E ratios greater than 33x and even P/E's higher than 62x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Zhejiang Runyang New Material 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 Zhejiang Runyang New Material Technology?

In order to justify its P/E ratio, Zhejiang Runyang New Material Technology would need to produce sluggish growth that's trailing the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 353% last year. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 62% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 38% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we are not surprised that Zhejiang Runyang New Material Technology is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

What We Can Learn From Zhejiang Runyang New Material Technology's P/E?

Despite Zhejiang Runyang New Material Technology's shares building up a head of steam, its P/E still lags most other companies. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

As we suspected, our examination of Zhejiang Runyang New Material Technology revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio.
