### How Do You Calculate A P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share Ã· Earnings per Share (EPS)

Or for Perrot Duval Holding:

P/E of 21.76 = CHF144.00 Ã· CHF6.62 (Based on the year to October 2019.)

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

A higher P/E ratio means that investors are paying a higher price for each CHF1 of company earnings. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### How Does Perrot Duval Holding's P/E Ratio Compare To Its Peers?

This suggests that market participants think Perrot Duval Holding will underperform other companies in its industry. Many investors like to buy stocks when the market is pessimistic about their prospects. You should delve deeper. I like to check if company insiders have been buying or selling.

### 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. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Perrot Duval Holding's earnings per share grew by -9.2% in the last twelve months. Unfortunately, earnings per share are down 2.0% a year, 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. 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.

### So What Does Perrot Duval Holding's Balance Sheet Tell Us?

Net debt totals 25% of Perrot Duval Holding's market cap. 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 Bottom Line On Perrot Duval Holding's P/E Ratio

Perrot Duval Holding trades on a P/E ratio of 21.8, which is fairly close to the CH market average of 20.3. Given it has some debt, and grew earnings a bit last year, the P/E indicates the market is expecting steady ongoing progress.
