# Here's What Illinois Tool Works Inc.'s (NYSE:ITW) P/E Ratio Is Telling Us

The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We'll apply a basic P/E ratio analysis to Illinois Tool Works Inc.'s (NYSE:ITW), to help you decide if the stock is worth further research. Illinois Tool Works has a P/E ratio of 20.99, based on the last twelve months. That corresponds to an earnings yield of approximately 4.8%.

### How Do I Calculate Illinois Tool Works's Price To Earnings Ratio?

The formula for P/E is:

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

Or for Illinois Tool Works:

P/E of 20.99 = \$158.64 Ã· \$7.56 (Based on the trailing twelve months to March 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 is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does Illinois Tool Works Have A Relatively High Or Low P/E For Its Industry?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. You can see in the image below that the average P/E (20.8) for companies in the machinery industry is roughly the same as Illinois Tool Works's P/E.

That indicates that the market expects Illinois Tool Works will perform roughly in line with other companies in its industry. If the company has better than average prospects, then the market might be underestimating it. Checking factors such as director buying and selling. could help you form your own view on if that will happen.

### 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. Earnings growth means that in the future the 'E' will be higher. That means unless the share price increases, the P/E will reduce in a few years. Then, a lower P/E should attract more buyers, pushing the share price up.

Illinois Tool Works increased earnings per share by a whopping 44% last year. And earnings per share have improved by 15% annually, over the last five years. So we'd generally expect it to have a relatively high P/E ratio.

### 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. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

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).

### Illinois Tool Works's Balance Sheet

Net debt totals 12% of Illinois Tool Works's market cap. It would probably deserve a higher P/E ratio if it was net cash, since it would have more options for growth.

### The Verdict On Illinois Tool Works's P/E Ratio

Illinois Tool Works trades on a P/E ratio of 21, which is above its market average of 18. Its debt levels do not imperil its balance sheet and its EPS growth is very healthy indeed. So to be frank we are not surprised it has a high P/E ratio.
