B & S International Holdings Ltd. (HKG:1705) shareholders have had their patience rewarded with a 33% share price jump in the last month. Taking a wider view, although not as strong as the last month, the full year gain of 19% is also fairly reasonable.

Although its price has surged higher, B & S International Holdings may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 4.8x, 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.

Earnings have risen firmly for B & S International Holdings recently, which is pleasing to see. It might be that many expect the respectable earnings performance to degrade substantially, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

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

B & S International Holdings' P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

Retrospectively, the last year delivered an exceptional 21% gain to the company's bottom line. Pleasingly, EPS has also lifted 5,666% 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 21% shows it's noticeably more attractive on an annualised basis.

In light of this, it's peculiar that B & S International Holdings' P/E sits below the majority of other companies. Apparently some shareholders believe the recent performance has exceeded its limits and have been accepting significantly lower selling prices.

What We Can Learn From B & S International Holdings' P/E?

Despite B & S International Holdings' shares building up a head of steam, its P/E still lags most other companies. 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.

We've established that B & S International Holdings currently trades on a much lower than expected P/E since its recent three-year growth is higher than the wider market forecast. There could be some major unobserved threats to earnings preventing the P/E ratio from matching this positive performance. 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.
