REF Holdings Limited (HKG:1631) shareholders are no doubt pleased to see that the share price has bounced 25% in the last month, although it is still struggling to make up recently lost ground. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 32% over that time.

In spite of the firm bounce in price, you could still be forgiven for feeling indifferent about REF Holdings' P/E ratio of 8.1x, since the median price-to-earnings (or "P/E") ratio in Hong Kong is also close to 10x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

For instance, REF Holdings' receding earnings in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The P/E?

The only time you'd be comfortable seeing a P/E like REF Holdings' is when the company's growth is tracking the market closely.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 39%. This means it has also seen a slide in earnings over the longer-term as EPS is down 55% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job 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 downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's somewhat alarming that REF Holdings' P/E sits in line with the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh on the share price eventually.

The Final Word

Its shares have lifted substantially and now REF Holdings' P/E is also back up to the market median. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that REF Holdings currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the moderate P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
