How Do I Calculate A Price To Earnings Ratio?
The formula for price to earnings is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for Autostrade Meridionali:
P/E of 6.53 = €31.10 ÷ €4.76 (Based on the trailing twelve months to June 2019.)
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. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.
Does Autostrade Meridionali 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. If you look at the image below, you can see Autostrade Meridionali has a lower P/E than the average (17.0) in the infrastructure industry classification.
This suggests that market participants think Autostrade Meridionali will underperform other companies in its industry. Since the market seems unimpressed with Autostrade Meridionali, it's quite possible it could surprise on the upside. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.
How Growth Rates Impact P/E Ratios
Earnings growth rates have a big influence on P/E ratios. When earnings grow, the 'E' increases, over time. That means unless the share price increases, the P/E will reduce in a few years. Then, a lower P/E should attract more buyers, pushing the share price up.
Autostrade Meridionali increased earnings per share by 9.2% last year. And earnings per share have improved by 49% annually, over the last five years.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
Don't forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.
Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.
