### How Do You Calculate International Business Machines's P/E Ratio?

The formula for P/E is:

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

P/E of 15.61 = \$135.27 Ã· \$8.67 (Based on the trailing twelve months to September 2019.)

### Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. 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 International Business Machines's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. The image below shows that International Business Machines has a lower P/E than the average (31.0) P/E for companies in the it industry.

This suggests that market participants think International Business Machines 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. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

When earnings fall, the 'E' decreases, over time. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. So while a stock may look cheap based on past earnings, it could be expensive based on future earnings.

International Business Machines increased earnings per share by a whopping 39% last year. Unfortunately, earnings per share are down 12% a year, over 5 years.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. That means it doesn't take debt or cash into account. 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.

### So What Does International Business Machines's Balance Sheet Tell Us?

International Business Machines's net debt equates to 46% of its market capitalization. While it's worth keeping this in mind, it isn't a worry.

### The Verdict On International Business Machines's P/E Ratio

International Business Machines has a P/E of 15.6. That's below the average in the US market, which is 18.9. The company does have a little debt, and EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified. Since analysts are predicting growth will continue, one might expect to see a higher P/E so it may be worth looking closer.
