RongFa Nuclear Equipment Co., Ltd.'s (SZSE:002366) price-to-earnings (or "P/E") ratio of 35.7x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 27x and even P/E's below 16x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

For example, consider that RongFa Nuclear Equipment's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

Does Growth Match The High P/E?

RongFa Nuclear Equipment's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Retrospectively, the last year delivered a frustrating 52% decrease to the company's bottom line. 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. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

This is in contrast to the rest of the market, which is expected to grow by 36% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that RongFa Nuclear Equipment's P/E sits above the majority of other companies. 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.

What We Can Learn From RongFa Nuclear Equipment's P/E?

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.

Our examination of RongFa Nuclear Equipment revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. 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.
