SUPCON Technology Co., Ltd.'s (SHSE:688777) price-to-earnings (or "P/E") ratio of 34.9x might 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 30x and even P/E's below 18x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

SUPCON Technology 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.

How Is SUPCON Technology's Growth Trending?

SUPCON Technology's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 30% last year. The strong recent performance means it was also able to grow EPS by 113% in total over the last three years. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 37% each year during the coming three years according to the analysts following the company. That's shaping up to be materially higher than the 22% per annum growth forecast for the broader market.

With this information, we can see why SUPCON Technology is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.
