Ziyuanyuan Holdings Group Limited (HKG:8223) shares have continued their recent momentum with a 43% gain in the last month alone. The last month tops off a massive increase of 101% in the last year.

After such a large jump in price, Ziyuanyuan Holdings Group's price-to-earnings (or "P/E") ratio of 74.6x might make it look like a strong sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 9x and even P/E's below 5x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Ziyuanyuan Holdings Group over the last year, which is not ideal at all. 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. 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?

Ziyuanyuan Holdings Group'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, dishearteningly the company's profits fell to the tune of 7.9%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Comparing that to the market, which is predicted to deliver 19% 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 Ziyuanyuan Holdings Group's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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 Ziyuanyuan Holdings Group's P/E?

The strong share price surge has got Ziyuanyuan Holdings Group's P/E rushing to great heights as well. 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 Ziyuanyuan Holdings Group 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 4 warning signs with Ziyuanyuan Holdings Group (at least 2 which are a bit concerning), and understanding them should be part of your investment process.
