The Flat Glass Group Co., Ltd. (HKG:6865) share price has done very well over the last month, posting an excellent gain of 29%. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 28% in the last twelve months.

Since its price has surged higher, Flat Glass Group may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 13.3x, since almost half of all companies in Hong Kong have P/E ratios under 8x and even P/E's lower than 5x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Flat Glass Group certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

The only time you'd be truly comfortable seeing a P/E as steep as Flat Glass Group's is when the company's growth is on track to outshine the market decidedly.

Taking a look back first, we see that the company grew earnings per share by an impressive 34% last year. Pleasingly, EPS has also lifted 106% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 19% per year as estimated by the analysts watching the company. That's shaping up to be materially higher than the 16% per annum growth forecast for the broader market.

In light of this, it's understandable that Flat Glass Group'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 Key Takeaway

The strong share price surge has got Flat Glass Group's P/E rushing to great heights as well. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

As we suspected, our examination of Flat Glass Group's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. It's hard to see the share price falling strongly in the near future under these circumstances.
