How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

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

Or for Zwahlen & Mayr:

P/E of 5.02 = CHF250 ÷ CHF49.81 (Based on the year to June 2018.)

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. 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. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Zwahlen & Mayr increased earnings per share by a whopping 355% last year. And its annual EPS growth rate over 5 years is 56%. With that performance, I would expect it to have an above average P/E ratio.

How Does Zwahlen & Mayr's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. The image below shows that Zwahlen & Mayr has a lower P/E than the average (10.4) P/E for companies in the construction industry.

This suggests that market participants think Zwahlen & Mayr 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. You should delve deeper. I like to check if company insiders have been buying or selling.

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. That means it doesn't take debt or cash into account. Theoretically, a business can improve its earnings (and produce a lower P/E in the future), by taking on debt (or spending its remaining cash).

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.

Is Debt Impacting Zwahlen & Mayr's P/E?

Zwahlen & Mayr has net debt worth 23% of its market capitalization. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

The Verdict On Zwahlen & Mayr's P/E Ratio

Zwahlen & Mayr has a P/E of 5. That's below the average in the CH market, which is 18.2. The company hasn't stretched its balance sheet, and earnings growth was good last year. The low P/E ratio suggests current market expectations are muted, implying these levels of growth will not continue.

Investors should be looking to buy stocks that the market is wrong about.
