It's not a stretch to say that Xinyi Solar Holdings Limited's (HKG:968) price-to-earnings (or "P/E") ratio of 10.9x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Xinyi Solar Holdings has been struggling lately as its earnings have declined faster than most other companies. It might be that many expect the dismal earnings performance to revert back to market averages soon, which has kept the P/E from falling. You'd much rather the company wasn't bleeding earnings if you still believe in the business. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

Does Growth Match The P/E?

In order to justify its P/E ratio, Xinyi Solar Holdings would need to produce growth that's similar to 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 12%. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Looking ahead now, EPS is anticipated to climb by 26% each year during the coming three years according to the analysts following the company. With the market only predicted to deliver 15% per year, the company is positioned for a stronger earnings result.

In light of this, it's curious that Xinyi Solar Holdings' P/E sits in line with the majority of other companies. It may be that most investors aren't convinced the company can achieve future growth expectations.
