Anhui Tongfeng Electronics Company Limited (SHSE:600237) shareholders are no doubt pleased to see that the share price has bounced 27% in the last month, although it is still struggling to make up recently lost ground. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 15% over that time.

Since its price has surged higher, Anhui Tongfeng Electronics may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 48.5x, since almost half of all companies in China have P/E ratios under 31x and even P/E's lower than 19x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

Recent times have been pleasing for Anhui Tongfeng Electronics as its earnings have risen in spite of the market's earnings going into reverse. 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 far outperform the market for P/E ratios like Anhui Tongfeng Electronics' to be considered reasonable.

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. That's essentially a continuation of what we've seen over the last three years, as its EPS growth has been virtually non-existent for that entire period. So it seems apparent to us that the company has struggled to grow earnings meaningfully over that time.

Turning to the outlook, the next year should generate growth of 96% as estimated by the two analysts watching the company. Meanwhile, the rest of the market is forecast to only expand by 40%, which is noticeably less attractive.

With this information, we can see why Anhui Tongfeng Electronics 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.

What We Can Learn From Anhui Tongfeng Electronics' P/E?

Shares in Anhui Tongfeng Electronics have built up some good momentum lately, which has really inflated its P/E. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.
