Ginlong Technologies Co., Ltd.'s (SZSE:300763) price-to-earnings (or "P/E") ratio of 52.6x 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 32x and even P/E's below 20x 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.

Ginlong Technologies could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. One possibility is that the P/E is high because investors think this poor earnings performance will turn the corner. If not, then existing shareholders may be extremely nervous about the viability of the share price.

Is There Enough Growth For Ginlong Technologies?

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

Retrospectively, the last year delivered a frustrating 63% decrease to the company's bottom line. This has soured the latest three-year period, which nevertheless managed to deliver a decent 17% overall rise in EPS. So we can start by confirming that the company has generally done a good job of growing earnings over that time, even though it had some hiccups along the way.

Looking ahead now, EPS is anticipated to climb by 44% each year during the coming three years according to the nine analysts following the company. That's shaping up to be materially higher than the 26% each year growth forecast for the broader market.

In light of this, it's understandable that Ginlong Technologies' P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.
