Unfortunately for some shareholders, the WebRAY Tech(Beijing) Co., Ltd. (SHSE:688651) share price has dived 29% in the last thirty days, prolonging recent pain. To make matters worse, the recent drop has wiped out a year's worth of gains with the share price now back where it started a year ago.

In spite of the heavy fall in price, WebRAY Tech(Beijing)'s price-to-earnings (or "P/E") ratio of 42.1x might still make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 29x and even P/E's below 18x 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 as high as it is.

WebRAY Tech(Beijing) hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. One possibility is that the P/E is high because investors think this poor earnings performance will turn the corner. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

There's an inherent assumption that a company should outperform the market for P/E ratios like WebRAY Tech(Beijing)'s to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 15%. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Looking ahead now, EPS is anticipated to climb by 73% during the coming year according to the one analyst following the company. That's shaping up to be materially higher than the 35% growth forecast for the broader market.

In light of this, it's understandable that WebRAY Tech(Beijing)'s 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.

The Final Word

WebRAY Tech(Beijing)'s P/E hasn't come down all the way after its stock plunged. 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.

We've established that WebRAY Tech(Beijing) maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. Unless these conditions change, they will continue to provide strong support to the share price.
