Those holding Tianjin Benefo Tejing Electric Co., Ltd. (SHSE:600468) shares would be relieved that the share price has rebounded 29% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Taking a wider view, although not as strong as the last month, the full year gain of 17% is also fairly reasonable.

After such a large jump in price, Tianjin Benefo Tejing Electric's price-to-earnings (or "P/E") ratio of 46x might make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 29x and even P/E's below 18x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Tianjin Benefo Tejing Electric has been doing a good job lately as it's been growing earnings at a solid pace. It might be that many expect the respectable earnings performance to beat most other companies over the coming period, 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?

Tianjin Benefo Tejing Electric's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

If we review the last year of earnings growth, the company posted a worthy increase of 13%. The solid recent performance means it was also able to grow EPS by 20% in total over the last three years. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Tianjin Benefo Tejing Electric is trading at a P/E higher than the market. It seems most investors are ignoring the fairly limited recent growth rates 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 recent growth rates.

The Key Takeaway

Tianjin Benefo Tejing Electric's P/E is flying high just like its stock has during the last month. 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.

We've established that Tianjin Benefo Tejing Electric currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
