Those holding Zhejiang Jinghua Laser Technology Co.,Ltd (SHSE:603607) shares would be relieved that the share price has rebounded 30% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. But the gains over the last month weren't enough to make shareholders whole, as the share price is still down 5.4% in the last twelve months.

Even after such a large jump in price, there still wouldn't be many who think Zhejiang Jinghua Laser TechnologyLtd's price-to-earnings (or "P/E") ratio of 28.5x is worth a mention when the median P/E in China is similar at about 30x. 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.

For example, consider that Zhejiang Jinghua Laser TechnologyLtd's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Some Growth For Zhejiang Jinghua Laser TechnologyLtd?

The only time you'd be comfortable seeing a P/E like Zhejiang Jinghua Laser TechnologyLtd's is when the company's growth is tracking the market closely.

Retrospectively, the last year delivered a frustrating 26% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 18% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 41% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Zhejiang Jinghua Laser TechnologyLtd is trading at a fairly similar P/E to the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Bottom Line On Zhejiang Jinghua Laser TechnologyLtd's P/E

Zhejiang Jinghua Laser TechnologyLtd's stock has a lot of momentum behind it lately, which has brought its P/E level with the market. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Zhejiang Jinghua Laser TechnologyLtd currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. Right now we are uncomfortable with the P/E as this earnings performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
