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

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. 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 Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company’s P/E multiple. If earnings are growing quickly, then the ‘E’ in the equation will increase faster than it would otherwise. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

W.W. Grainger increased earnings per share by an impressive 11% over the last twelve months. And earnings per share have improved by 6.0% annually, over the last five years. With that performance, you might expect an above average P/E ratio.

### Don’t Forget: The P/E Does Not Account For Debt or Bank Deposits

The ‘Price’ in P/E reflects the market capitalization of the company. That means it doesn’t take debt or cash into account. 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).

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 W.W. Grainger’s P/E?

W.W. Grainger’s net debt is 11% of its 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 Bottom Line On W.W. Grainger’s P/E Ratio

W.W. Grainger trades on a P/E ratio of 19.5, which is fairly close to the US market average of 18.2. When you consider the impressive EPS growth last year (along with some debt), it seems the market has questions about whether rapid EPS growth will be sustained. Given analysts are expecting further growth, one might have expected a higher P/E ratio. That may be worth further research.
