Able Engineering Holdings Limited (HKG:1627) shares have continued their recent momentum with a 27% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 54%.

Even after such a large jump in price, Able Engineering Holdings may still be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 4.7x, since almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 20x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

With earnings growth that's exceedingly strong of late, Able Engineering Holdings has been doing very well. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

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

Able Engineering Holdings' P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 30% last year. Pleasingly, EPS has also lifted 127% in aggregate from three years ago, thanks to the last 12 months of growth. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 23% shows it's noticeably more attractive on an annualised basis.

With this information, we find it odd that Able Engineering Holdings is trading at a P/E lower than the market. Apparently some shareholders believe the recent performance has exceeded its limits and have been accepting significantly lower selling prices.

The Key Takeaway

Shares in Able Engineering Holdings are going to need a lot more upward momentum to get the company's P/E out of its slump. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Able Engineering Holdings revealed its three-year earnings trends aren't contributing to its P/E anywhere near as much as we would have predicted, given they look better than current market expectations. When we see strong earnings with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. At least price risks look to be very low if recent medium-term earnings trends continue, but investors seem to think future earnings could see a lot of volatility.
