Those holding Yadong Group Holdings Limited (HKG:1795) 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. But the last month did very little to improve the 62% share price decline over the last year.

After such a large jump in price, given close to half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") below 9x, you may consider Yadong Group Holdings as a stock to avoid entirely with its 18.7x P/E ratio. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For instance, Yadong Group Holdings' receding earnings in recent times would have to be some food for thought. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?

Yadong Group Holdings' 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.

Retrospectively, the last year delivered a frustrating 31% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 25% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 21% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Yadong Group Holdings is trading at a P/E higher than the market. 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. 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 Yadong Group Holdings' P/E

Shares in Yadong Group Holdings have built up some good momentum lately, which has really inflated its P/E. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Yadong Group Holdings revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, 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 5 warning signs with Yadong Group Holdings (at least 2 which shouldn't be ignored), and understanding these should be part of your investment process.
