A & S Group (Holdings) Limited (HKG:1737) shareholders have had their patience rewarded with a 30% share price jump in the last month. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Although its price has surged higher, A & S Group (Holdings) may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 7.4x, since almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 19x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

A & S Group (Holdings) certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. 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.

How Is A & S Group (Holdings)'s Growth Trending?

The only time you'd be truly comfortable seeing a P/E as low as A & S Group (Holdings)'s is when the company's growth is on track to lag the market.

If we review the last year of earnings growth, the company posted a terrific increase of 105%. However, this wasn't enough as the latest three year period has seen a very unpleasant 56% drop in EPS in aggregate. 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 understandable that A & S Group (Holdings)'s P/E would sit below the majority of other companies. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Final Word

A & S Group (Holdings)'s stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of A & S Group (Holdings) revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
