How Do You Calculate A P/E Ratio?

The formula for P/E is:

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

Or for BWX:

P/E of 39.19 = A$3.520 ÷ A$0.090 (Based on the trailing twelve months to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

Is A High P/E Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. 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'.

Does BWX 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. The image below shows that BWX has a higher P/E than the average (21.4) P/E for companies in the personal products industry.

BWX's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isn't guaranteed. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

How Growth Rates Impact P/E Ratios

If earnings fall then in the future the 'E' will be lower. That means unless the share price falls, the P/E will increase in a few years. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

BWX saw earnings per share decrease by 33% last year. And over the longer term (3 years) earnings per share have decreased 16% annually. This might lead to low expectations.

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

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.

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.

BWX's Balance Sheet

BWX's net debt is 3.4% of its market cap. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

The Bottom Line On BWX's P/E Ratio

BWX has a P/E of 39.2. That's higher than the average in its market, which is 15.9. With a bit of debt, but a lack of recent growth, it's safe to say the market is expecting improved profit performance from the company, in the next few years.
