To the annoyance of some shareholders, Fulu Holdings Limited (HKG:2101) shares are down a considerable 29% in the last month, which continues a horrid run for the company. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 36% in that time.

Even after such a large drop in price, given around half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") below 9x, you may still consider Fulu Holdings as a stock to potentially avoid with its 11.7x 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.

Fulu Holdings certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

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 Fulu Holdings' to be considered reasonable.

If we review the last year of earnings growth, the company posted a terrific increase of 43%. However, this wasn't enough as the latest three year period has seen a very unpleasant 11% drop in EPS in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 25% shows it's an unpleasant look.

In light of this, it's alarming that Fulu Holdings' P/E sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate 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 Key Takeaway

Fulu Holdings' P/E hasn't come down all the way after its stock plunged. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Fulu 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.

Don't forget that there may be other risks. For instance, we've identified 2 warning signs for Fulu Holdings (1 doesn't sit too well with us) you should be aware of.
