### How Do I Calculate A 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 Group:

P/E of 13.93 = AUD0.80 Ã· AUD0.06 (Based on the trailing twelve months to June 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each AUD1 the company has earned over the last year. All else being equal, it's better to pay a low price -- but as Warren Buffett said, 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price'.

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

The P/E ratio indicates whether the market has higher or lower expectations of a company. The image below shows that Group has a lower P/E than the average (25.9) P/E for companies in the aerospace & defense industry.

Its relatively low P/E ratio indicates that Group 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. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

If earnings fall then in the future the 'E' will be lower. That means even if the current P/E is low, it will increase over time if the share price stays flat. So while a stock may look cheap based on past earnings, it could be expensive based on future earnings.

It's great to see that Group grew EPS by 10% in the last year. But earnings per share are down 2.1% per year over the last three years.

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

Don't forget that the P/E ratio considers market capitalization. So it won't reflect the advantage of cash, or disadvantage of debt. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

### How Does Group's Debt Impact Its P/E Ratio?

Group's net debt is 14% of its market cap. This could bring some additional risk, and reduce the number of investment options for management; worth remembering if you compare its P/E to businesses without debt.

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

Group's P/E is 13.9 which is below average (19.0) in the AU market. The company does have a little debt, and EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified.

Investors have an opportunity when market expectations about a stock are wrong. 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. We don't have analyst forecasts, but shareholders might want to examine this detailed historical graph of earnings, revenue and cash flow.
