This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We'll show how you can use Ashtead Group plc's (LON:AHT) P/E ratio to inform your assessment of the investment opportunity. Ashtead Group has a price to earnings ratio of 13.84, based on the last twelve months. That is equivalent to an earnings yield of about 7.2%.
How Do I Calculate Ashtead Group's Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for Ashtead Group:
P/E of 13.84 = £23.80 ÷ £1.72 (Based on the trailing twelve months to July 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 Ashtead Group Have A Relatively High Or Low P/E For Its Industry?
We can get an indication of market expectations by looking at the P/E ratio. We can see in the image below that the average P/E (15.3) for companies in the trade distributors industry is higher than Ashtead Group's P/E.
This suggests that market participants think Ashtead Group will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. 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
P/E ratios primarily reflect market expectations around earnings growth rates. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. And in that case, the P/E ratio itself will drop rather quickly. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.
Ashtead Group shrunk earnings per share by 17% over the last year. But over the longer term (5 years) earnings per share have increased by 29%.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
The 'Price' in P/E reflects the market capitalization of the company. So it won't reflect the advantage of cash, or disadvantage of debt. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.
While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.
Is Debt Impacting Ashtead Group's P/E?
Ashtead Group has net debt equal to 39% of its market cap. While that's enough to warrant consideration, it doesn't really concern us.
The Verdict On Ashtead Group's P/E Ratio
Ashtead Group trades on a P/E ratio of 13.8, which is below the GB market average of 16.9. Since it only carries a modest debt load, it's likely the low expectations implied by the P/E ratio arise from the lack of recent earnings growth.
