Sino Land Company Limited's (HKG:83) price-to-earnings (or "P/E") ratio of 11.6x might make it look like a sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 9x and even P/E's below 5x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

Sino Land certainly has been doing a good job lately as it's been growing earnings more than most other companies. The P/E is probably high because investors think this strong earnings performance will continue. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

In order to justify its P/E ratio, Sino Land would need to produce impressive growth in excess of the market.

Retrospectively, the last year delivered an exceptional 43% gain to the company's bottom line. The strong recent performance means it was also able to grow EPS by 2,420% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Shifting to the future, estimates from the twelve analysts covering the company suggest earnings should grow by 1.4% each year over the next three years. That's shaping up to be materially lower than the 15% each year growth forecast for the broader market.

In light of this, it's alarming that Sino Land's P/E sits above the majority of other companies. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

The Final Word

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 Sino Land currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Sino Land, and understanding should be part of your investment process.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
