AUX International Holdings Limited (HKG:2080) shareholders would be excited to see that the share price has had a great month, posting a 68% gain and recovering from prior weakness. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 3.5% over the last year.

Even after such a large jump in price, AUX International Holdings' price-to-earnings (or "P/E") ratio of 4.6x might still make it look like a strong buy right now compared to the market in Hong Kong, where around half of the companies have P/E ratios above 11x and even P/E's above 21x 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 so limited.

For instance, AUX International Holdings' receding earnings in recent times would have to be some food for thought. It might be that many expect the disappointing earnings performance to continue or accelerate, 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?

The only time you'd be truly comfortable seeing a P/E as depressed as AUX International Holdings' is when the company's growth is on track to lag the market decidedly.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 43%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 22% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

With this information, we can see why AUX International Holdings is trading at a P/E lower than the market. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

Even after such a strong price move, AUX International Holdings' P/E still trails the rest of the market significantly. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that AUX International Holdings maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. If recent medium-term earnings trends continue, it's hard to see the share price rising strongly in the near future under these circumstances.
