How Do You Calculate A P/E Ratio?
The formula for price to earnings is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for Derichebourg:
P/E of 8.22 = €3.27 ÷ €0.40 (Based on the trailing twelve months to March 2019.)
Is A High Price-to-Earnings Ratio Good?
A higher P/E ratio means that investors are paying a higher price for each €1 of company earnings. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.
Does Derichebourg Have A Relatively High Or Low P/E For Its Industry?
The P/E ratio indicates whether the market has higher or lower expectations of a company. The image below shows that Derichebourg has a lower P/E than the average (16.5) P/E for companies in the commercial services industry.
Derichebourg's P/E tells us that market participants think it will not fare as well as its peers in the same industry. Many investors like to buy stocks when the market is pessimistic about their prospects. You should delve deeper. I like to check if company insiders have been buying or selling.
How Growth Rates Impact P/E Ratios
Probably the most important factor in determining what P/E a company trades on is the earnings growth. When earnings grow, the 'E' increases, over time. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.
Derichebourg's earnings per share fell by 18% in the last twelve months. But it has grown its earnings per share by 49% per year over the last three years.
Don't Forget: The P/E Does Not Account For Debt or Bank Deposits
One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. Thus, the metric does not reflect cash or debt held by the company. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.
Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.
