Arctech Solar Holding Co., Ltd.'s (SHSE:688408) price-to-earnings (or "P/E") ratio of 23.8x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 27x and even P/E's above 51x are quite common. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

With earnings growth that's superior to most other companies of late, Arctech Solar Holding has been doing relatively well. One possibility is that the P/E is low because investors think this strong earnings performance might be less impressive moving forward. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Is There Any Growth For Arctech Solar Holding?

In order to justify its P/E ratio, Arctech Solar Holding would need to produce sluggish growth that's trailing the market.

Retrospectively, the last year delivered an exceptional 399% gain to the company's bottom line. The strong recent performance means it was also able to grow EPS by 48% in total over the last three years. 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 29% per year as estimated by the four analysts watching the company. With the market only predicted to deliver 24% per annum, the company is positioned for a stronger earnings result.

With this information, we find it odd that Arctech Solar Holding is trading at a P/E lower than the market. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Arctech Solar Holding currently trades on a much lower than expected P/E since its forecast growth is higher than the wider market. There could be some major unobserved threats to earnings preventing the P/E ratio from matching the positive outlook. At least price risks look to be very low, but investors seem to think future earnings could see a lot of volatility.
