How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. When earnings grow, the 'E' increases, over time. 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.

Most would be impressed by Rockwell Automation earnings growth of 15% in the last year. And earnings per share have improved by 5.2% annually, over the last five years. So one might expect an above average P/E ratio.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. 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.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

Rockwell Automation's Balance Sheet

Rockwell Automation's net debt is 6.0% of its market cap. The market might award it a higher P/E ratio if it had net cash, but its unlikely this low level of net borrowing is having a big impact on the P/E multiple.

The Verdict On Rockwell Automation's P/E Ratio

Rockwell Automation has a P/E of 23.6. That's higher than the average in its market, which is 16.9. Its debt levels do not imperil its balance sheet and it is growing EPS strongly. So on this analysis it seems reasonable that its P/E ratio is above average.
