With a median price-to-earnings (or "P/E") ratio of close to 9x in Hong Kong, you could be forgiven for feeling indifferent about Lygend Resources & Technology Co., Ltd.'s (HKG:2245) P/E ratio of 7.9x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

For instance, Lygend Resources & Technology's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

In order to justify its P/E ratio, Lygend Resources & Technology would need to produce growth that's similar to the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 48%. This means it has also seen a slide in earnings over the longer-term as EPS is down 34% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 20% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's somewhat alarming that Lygend Resources & Technology's P/E sits in line with 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. 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 the recent negative growth rates.

What We Can Learn From Lygend Resources & Technology's P/E?
