Xiamen Leading Optics Co., Ltd. (SHSE:605118) Stock Rockets 25% As Investors Are Less Pessimistic Than Expected

Xiamen Leading Optics Co., Ltd. (SHSE:605118) shares have continued their recent momentum with a 25% gain in the last month alone. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

After such a large jump in price, Xiamen Leading Optics' price-to-earnings (or "P/E") ratio of 57.2x might 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 33x and even P/E's below 19x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Earnings have risen firmly for Xiamen Leading Optics recently, which is pleasing to see. One possibility is that the P/E is high because investors think this respectable earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Xiamen Leading Optics' to be considered reasonable.

Retrospectively, the last year delivered a decent 13% gain to the company's bottom line. However, due to its less than impressive performance prior to this period, EPS growth is practically non-existent over the last three years overall. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

In contrast to the company, the rest of the market is expected to grow by 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Xiamen Leading Optics is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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 Xiamen Leading Optics' P/E?

Shares in Xiamen Leading Optics have built up some good momentum lately, which has really inflated its P/E. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of Xiamen Leading Optics revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. 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.
