The New East New Materials Co., Ltd (SHSE:603110) share price has softened a substantial 25% over the previous 30 days, handing back much of the gains the stock has made lately. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 44% share price drop.

Although its price has dipped substantially, New East New Materials' price-to-earnings (or "P/E") ratio of 53.2x might still make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 32x and even P/E's below 19x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

With earnings growth that's exceedingly strong of late, New East New Materials has been doing very well. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is New East New Materials' Growth Trending?

In order to justify its P/E ratio, New East New Materials would need to produce outstanding growth well in excess of the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 177% last year. Despite this strong recent growth, it's still struggling to catch up as its three-year EPS frustratingly shrank by 27% 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 find it concerning that New East New Materials is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate 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 earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From New East New Materials' P/E?

A significant share price dive has done very little to deflate New East New Materials' very lofty P/E. 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.

We've established that New East New Materials currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
