KPa-BM Holdings Limited (HKG:2663) shares have continued their recent momentum with a 25% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 53%.

Although its price has surged higher, KPa-BM Holdings' price-to-earnings (or "P/E") ratio of 5x might still make it look like a buy right now compared to the market in Hong Kong, where around half of the companies have P/E ratios above 10x and even P/E's above 19x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

With earnings growth that's exceedingly strong of late, KPa-BM Holdings has been doing very well. It might be that many expect the strong 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.

Does Growth Match The Low P/E?

The only time you'd be truly comfortable seeing a P/E as low as KPa-BM Holdings' is when the company's growth is on track to lag the market.

Retrospectively, the last year delivered an exceptional 33% gain to the company's bottom line. Still, EPS has barely risen at all from three years ago in total, which is not ideal. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 21% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's understandable that KPa-BM Holdings' P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

What We Can Learn From KPa-BM Holdings' P/E?

Despite KPa-BM Holdings' shares building up a head of steam, its P/E still lags most other companies. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

As we suspected, our examination of KPa-BM Holdings revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow.
