Today, we’ll introduce the concept of the P/E ratio for those who are learning about investing. We’ll apply a basic P/E ratio analysis to PORR AG’s (VIE:POS), to help you decide if the stock is worth further research. What is PORR’s P/E ratio? Well, based on the last twelve months it is 10.68. That is equivalent to an earnings yield of about 9.4%.

### 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 PORR:

P/E of 10.68 = €23.2 ÷ €2.17 (Based on the year to December 2018.)

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

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. 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 Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. If earnings are growing quickly, then the ‘E’ in the equation will increase faster than it would otherwise. 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.

PORR increased earnings per share by 3.7% last year. And earnings per share have improved by 2.3% annually, over the last five years.

### Does PORR 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 PORR has a higher P/E than the average (8.4) P/E for companies in the construction industry.

Its relatively high P/E ratio indicates that PORR shareholders think it will perform better than other companies in its industry classification. The market is optimistic about the future, but that doesn’t guarantee future growth. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

### 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. That means it doesn’t take debt or cash into account. 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.

### Is Debt Impacting PORR’s P/E?

PORR has net debt worth 13% of its market capitalization. It would probably deserve a higher P/E ratio if it was net cash, since it would have more options for growth.

### The Verdict On PORR’s P/E Ratio

PORR trades on a P/E ratio of 10.7, which is below the AT market average of 14.9. EPS grew over the last twelve months, and debt levels are quite reasonable. If you believe growth will continue – or even increase – then the low P/E may signify opportunity.

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. So this free visualization of the analyst consensus on future earnings could help you make the right decision about whether to buy, sell, or hold.
