Naipu Mining Machinery Co., Ltd. (SZSE:300818) shareholders won't be pleased to see that the share price has had a very rough month, dropping 26% and undoing the prior period's positive performance. Longer-term, the stock has been solid despite a difficult 30 days, gaining 11% in the last year.
Although its price has dipped substantially, given around half the companies in China have price-to-earnings ratios (or "P/E's") below 27x, you may still consider Naipu Mining Machinery as a stock to potentially avoid with its 39.4x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.
As an illustration, earnings have deteriorated at Naipu Mining Machinery over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. 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 Naipu Mining Machinery's to be considered reasonable.
Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 70%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 53% in total over the last three years. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.
Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 42% shows it's noticeably less attractive on an annualised basis.
In light of this, it's alarming that Naipu Mining Machinery'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. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.
The Bottom Line On Naipu Mining Machinery's P/E
Despite the recent share price weakness, Naipu Mining Machinery's P/E remains higher than most other companies. 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.
We've established that Naipu Mining Machinery currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
