It's not a stretch to say that MMG Limited's (HKG:1208) price-to-earnings (or "P/E") ratio of 7x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

MMG hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. One possibility is that the P/E is moderate because investors think this poor earnings performance will turn around. 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?

The only time you'd be comfortable seeing a P/E like MMG's is when the company's growth is tracking the market closely.

Retrospectively, the last year delivered a frustrating 34% decrease to the company's bottom line. 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.

Turning to the outlook, the next three years should generate growth of 26% per year as estimated by the nine analysts watching the company. With the market only predicted to deliver 15% per year, the company is positioned for a stronger earnings result.

In light of this, it's curious that MMG's P/E sits in line with the majority of other companies. It may be that most investors aren't convinced the company can achieve future growth expectations.

The Final Word

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 MMG currently trades on a lower than expected P/E since its forecast growth is higher than the wider market. When we see a strong earnings outlook with faster-than-market growth, we assume potential risks are what might be placing pressure on the P/E ratio. At least the risk of a price drop looks to be subdued, but investors seem to think future earnings could see some volatility.
