# Why ABB Ltd's (VTX:ABBN) High P/E Ratio Isn't Necessarily A Bad Thing

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 ABB Ltd's (VTX:ABBN) P/E ratio could help you assess the value on offer. Looking at earnings over the last twelve months, ABB has a P/E ratio of 44.99. That means that at current prices, buyers pay CHF44.99 for every CHF1 in trailing yearly profits.

### How Do You Calculate ABB's P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price (in reporting currency) Ã· Earnings per Share (EPS)

Or for ABB:

P/E of 44.99 = \$18.66 (Note: this is the share price in the reporting currency, namely, USD ) Ã· \$0.41 (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 isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### How Does ABB's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. The image below shows that ABB has a higher P/E than the average (19.2) P/E for companies in the electrical industry.

That means that the market expects ABB will outperform other companies in its industry. Clearly the market expects growth, but it isn't guaranteed. So investors should delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

If earnings fall then in the future the 'E' will be lower. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

ABB's earnings per share fell by 11% in the last twelve months. And it has shrunk its earnings per share by 18% per year over the last five years. This could justify a pessimistic P/E.

### Remember: P/E Ratios Don't Consider The Balance Sheet

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. So it won't reflect the advantage of cash, or disadvantage of debt. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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 ABB's P/E?

Net debt totals 17% of ABB's market cap. This could bring some additional risk, and reduce the number of investment options for management; worth remembering if you compare its P/E to businesses without debt.

### The Bottom Line On ABB's P/E Ratio

ABB trades on a P/E ratio of 45, which is above its market average of 17.7. With modest debt but no EPS growth in the last year, it's fair to say the P/E implies some optimism about future earnings, from the market.
