How Do I Calculate A Price To Earnings Ratio?
The formula for price to earnings is:
Price to Earnings Ratio = Price per Share (in the reporting currency) ÷ Earnings per Share (EPS)
Or for Binjiang Services Group:
P/E of 18.14 = CN¥6.37 (Note: this is the share price in the reporting currency, namely, CNY ) ÷ CN¥0.35 (Based on the trailing twelve months to December 2018.)
Is A High Price-to-Earnings Ratio Good?
The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. All else being equal, it's better to pay a low price -- but as Warren Buffett said, 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'
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. And in that case, the P/E ratio itself will drop rather quickly. Then, a lower P/E should attract more buyers, pushing the share price up.
It's great to see that Binjiang Services Group grew EPS by 23% in the last year. And it has bolstered its earnings per share by 44% per year over the last five years. This could arguably justify a relatively high P/E ratio.
