How Do I Calculate A Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Share Price (in reporting currency) ÷ Earnings per Share (EPS)
Or for Wenzhou Kangning Hospital:
P/E of 14.80 = HK$18.37 (Note: this is the share price in the reporting currency, namely, CNY ) ÷ HK$1.24 (Based on the year to June 2019.)
Is A High Price-to-Earnings Ratio Good?
A higher P/E ratio implies that investors pay a higher price for the earning power of the business. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.
How Does Wenzhou Kangning Hospital's P/E Ratio Compare To Its Peers?
The P/E ratio essentially measures market expectations of a company. The image below shows that Wenzhou Kangning Hospital has a P/E ratio that is roughly in line with the healthcare industry average (14.4).
That indicates that the market expects Wenzhou Kangning Hospital will perform roughly in line with other companies in its industry.

I would further inform my view by checking insider buying and selling., among other things.
How Growth Rates Impact P/E Ratios
P/E ratios primarily reflect market expectations around earnings growth rates. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. And as that P/E ratio drops, the company will look cheap, unless its share price increases.
It's nice to see that Wenzhou Kangning Hospital grew EPS by a stonking 40% in the last year. And earnings per share have improved by 9.9% annually, over the last five years. With that performance, I would expect it to have an above average P/E ratio.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. In other words, it does not consider any debt or cash that the company may have on the balance sheet. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.
