How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

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

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

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each CHF1 the company has earned over the last year. 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.

Does Stadler Rail 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. You can see in the image below that the average P/E (18.2) for companies in the machinery industry is lower than Stadler Rail's P/E.

How Growth Rates Impact P/E Ratios

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. That means unless the share price falls, the P/E will increase in a few years. Then, a higher P/E might scare off shareholders, pushing the share price down.

Stadler Rail saw earnings per share improve by 7.8% last year. In contrast, EPS has decreased by 6.1%, annually, over 5 years.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. Thus, the metric does not reflect cash or debt held by the company. In theory, a company can lower its future P/E ratio by using cash or debt to invest in 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.

How Does Stadler Rail's Debt Impact Its P/E Ratio?

Stadler Rail has net cash of CHF52m. That should lead to a higher P/E than if it did have debt, because its strong balance sheets gives it more options.

The Bottom Line On Stadler Rail's P/E Ratio

Stadler Rail trades on a P/E ratio of 32.1, which is above its market average of 17.7. EPS was up modestly better over the last twelve months. Also positive, the relatively strong balance sheet will allow for investment in growth -- and the P/E indicates shareholders that will happen!
