With a price-to-earnings (or "P/E") ratio of 39.8x Raytron Technology Co.,Ltd. (SHSE:688002) may be sending bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 34x and even P/E's lower than 20x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

Raytron TechnologyLtd 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

There's an inherent assumption that a company should outperform the market for P/E ratios like Raytron TechnologyLtd's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 73% gain to the company's bottom line. Still, incredibly EPS has fallen 8.9% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 39% during the coming year according to the seven analysts following the company. Meanwhile, the rest of the market is forecast to expand by 44%, which is noticeably more attractive.

In light of this, it's alarming that Raytron TechnologyLtd's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

The Key Takeaway

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.
