Casa Holdings Limited (SGX:C04) shareholders have had their patience rewarded with a 45% share price jump in the last month. Longer-term shareholders would be thankful for the recovery in the share price since it's now virtually flat for the year after the recent bounce.

Following the firm bounce in price, Casa Holdings' price-to-earnings (or "P/E") ratio of 18.3x might make it look like a strong sell right now compared to the market in Singapore, where around half of the companies have P/E ratios below 11x and even P/E's below 7x 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 lofty.

As an illustration, earnings have deteriorated at Casa Holdings over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Growth For Casa Holdings?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Casa Holdings' to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 22%. The last three years don't look nice either as the company has shrunk EPS by 21% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 12% 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 alarming that Casa Holdings' P/E sits above 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

What We Can Learn From Casa Holdings' P/E?

Shares in Casa Holdings have built up some good momentum lately, which has really inflated its P/E. 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.

Our examination of Casa Holdings revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

And what about other risks? Every company has them, and we've spotted 3 warning signs for Casa Holdings (of which 2 are potentially serious!) you should know about.
