Royal Deluxe Holdings Limited (HKG:3789) shareholders won't be pleased to see that the share price has had a very rough month, dropping 36% and undoing the prior period's positive performance. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 45% in that time.

Although its price has dipped substantially, Royal Deluxe Holdings' price-to-earnings (or "P/E") ratio of 6.4x 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. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

For instance, Royal Deluxe 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?

In order to justify its P/E ratio, Royal Deluxe Holdings would need to produce sluggish growth that's trailing the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 54%. As a result, earnings from three years ago have also fallen 74% overall. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 20% 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 Royal Deluxe 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.

The Key Takeaway

The softening of Royal Deluxe Holdings' shares means its P/E is now sitting at a pretty low level. 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 Royal Deluxe Holdings maintains its low P/E on the weakness of its sliding earnings over the medium-term, 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. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
