It's not a stretch to say that Jiangsu Cnano Technology Co., Ltd.'s (SHSE:688116) price-to-earnings (or "P/E") ratio of 36.9x right now seems quite "middle-of-the-road" compared to the market in China, where the median P/E ratio is around 34x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

With earnings that are retreating more than the market's of late, Jiangsu Cnano Technology has been very sluggish. One possibility is that the P/E is moderate because investors think the company's earnings trend will eventually fall in line with most others in the market. You'd much rather the company wasn't bleeding earnings if you still believe in the business. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The P/E?

Jiangsu Cnano Technology's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 39%. Even so, admirably EPS has lifted 171% in aggregate from three years ago, notwithstanding the last 12 months. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Shifting to the future, estimates from the six analysts covering the company suggest earnings should grow by 84% over the next year. With the market only predicted to deliver 43%, the company is positioned for a stronger earnings result.

In light of this, it's curious that Jiangsu Cnano Technology's P/E sits in line with the majority of other companies. Apparently some shareholders are skeptical of the forecasts and have been accepting lower selling prices.
