Unpleasant Surprises Could Be In Store For Naipu Mining Machinery Co., Ltd.'s (SZSE:300818) Shares

Naipu Mining Machinery Co., Ltd.'s (SZSE:300818) price-to-earnings (or "P/E") ratio of 57x 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 30x 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.

For example, consider that Naipu Mining Machinery's financial performance has been poor lately as its earnings have been in decline. 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?

In order to justify its P/E ratio, Naipu Mining Machinery would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 70%. Even so, admirably EPS has lifted 53% in aggregate from three years ago, notwithstanding the last 12 months. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 39% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

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. 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

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

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.
