### How Do I Calculate Caterpillar's Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for Caterpillar:

P/E of 10.86 = \$117.97 Ã· \$10.86 (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 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.

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

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 Caterpillar has a lower P/E than the average (19.2) in the machinery industry classification.

Its relatively low P/E ratio indicates that Caterpillar shareholders think it will struggle to do as well as other companies in its industry classification. 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

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. 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.

Caterpillar's 107% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive. And earnings per share have improved by 70% annually, over the last three years. So we'd absolutely expect it to have a relatively high P/E ratio.

### 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. So it won't reflect the advantage of cash, or disadvantage of debt. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

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.

### Caterpillar's Balance Sheet

Caterpillar's net debt equates to 45% of its market capitalization. While it's worth keeping this in mind, it isn't a worry.

### The Verdict On Caterpillar's P/E Ratio

Caterpillar trades on a P/E ratio of 10.9, which is below the US market average of 17.2. The EPS growth last year was strong, and debt levels are quite reasonable. If the company can continue to grow earnings, then the current P/E may be unjustifiably low.

Investors should be looking to buy stocks that the market is wrong about. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
