The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). To keep it practical, we'll show how Duke Energy Corporation's (NYSE:DUK) P/E ratio could help you assess the value on offer. Looking at earnings over the last twelve months, Duke Energy has a P/E ratio of 20.88. That is equivalent to an earnings yield of about 4.8%.
How Do I Calculate Duke Energy's Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)
Or for Duke Energy:
P/E of 20.88 = $93.76 ÷ $4.49 (Based on the trailing twelve months 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.
Does Duke Energy 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 Duke Energy has a lower P/E than the average (23.2) P/E for companies in the electric utilities industry.
Duke Energy'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. 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
Probably the most important factor in determining what P/E a company trades on is the earnings growth. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means even if the current P/E is high, it will reduce over time if the share price stays flat. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.
Duke Energy increased earnings per share by an impressive 13% over the last twelve months. And earnings per share have improved by 7.9% annually, over the last three years. So one might expect an above average P/E ratio.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
The 'Price' in P/E reflects the market capitalization of the company. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.
Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).
Is Debt Impacting Duke Energy's P/E?
Net debt totals 87% of Duke Energy's market cap. This is a reasonably significant level of debt -- all else being equal you'd expect a much lower P/E than if it had net cash.
The Verdict On Duke Energy's P/E Ratio
Duke Energy trades on a P/E ratio of 20.9, which is above its market average of 17.5. While the meaningful level of debt does limit its options, it has achieved solid growth over the last year. The relatively high P/E ratio suggests shareholders think growth will continue.
