How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for F5 Networks:

P/E of 18.82 = $153.69 ÷ $8.17 (Based on the trailing twelve months to December 2018.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each $1 of company 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

Earnings growth rates have a big influence on P/E ratios. 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. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

F5 Networks increased earnings per share by an impressive 25% over the last twelve months. And it has bolstered its earnings per share by 15% per year over the last five years. This could arguably justify a relatively high P/E ratio.

How Does F5 Networks’s P/E Ratio Compare To Its Peers?

This suggests that market participants think F5 Networks 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. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

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. In other words, it does not consider any debt or cash that the company may have on the balance sheet. In theory, a company can lower its future P/E ratio by using cash or debt to invest in 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).

F5 Networks’s Balance Sheet

Since F5 Networks holds net cash of US$1.1b, it can spend on growth, justifying a higher P/E ratio than otherwise.

The Verdict On F5 Networks’s P/E Ratio

F5 Networks trades on a P/E ratio of 18.8, which is fairly close to the US market average of 17.6. The balance sheet is healthy, and recent EPS growth impressive, but the P/E implies some caution from the market.
