Those holding Colour Life Services Group Co., Limited (HKG:1778) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. 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.

Since its price has surged higher, Colour Life Services Group may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 13x, since almost half of all companies in Hong Kong have P/E ratios under 9x and even P/E's lower than 5x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

For instance, Colour Life Services Group's receding earnings in recent times would have to be some food for thought. 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

Colour Life Services Group's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 27%. The last three years don't look nice either as the company has shrunk EPS by 96% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Comparing that to the market, which is predicted to deliver 20% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Colour Life Services Group is trading at a P/E higher than the market. 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.

The Bottom Line On Colour Life Services Group's P/E

Colour Life Services Group shares have received a push in the right direction, but its P/E is elevated too. 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 Colour Life Services Group currently trades on a much 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 high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
