Check out our latest analysis for Wärtsilä Oyj Abp

### 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 Wärtsilä Oyj Abp:

P/E of 19.53 = €8.88 ÷ €0.45 (Based on the trailing twelve months to September 2019.)

### 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 Does Wärtsilä Oyj Abp's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. The image below shows that Wärtsilä Oyj Abp has a higher P/E than the average (16.1) P/E for companies in the machinery industry.

Wärtsilä Oyj Abp's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Shareholders are clearly optimistic, but the future is always uncertain. So further research is always essential. I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

When earnings fall, the 'E' decreases, over time. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. Then, a higher P/E might scare off shareholders, pushing the share price down.

Wärtsilä Oyj Abp's earnings per share fell by 33% in the last twelve months. And EPS is down 8.2% a year, over the last 5 years. This might lead to muted expectations.

### 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. So it won't reflect the advantage of cash, or disadvantage of debt. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its 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.

### How Does Wärtsilä Oyj Abp's Debt Impact Its P/E Ratio?

Wärtsilä Oyj Abp's net debt is 15% of its 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 Wärtsilä Oyj Abp's P/E Ratio

Wärtsilä Oyj Abp has a P/E of 19.5. That's around the same as the average in the FI market, which is 19.3. With modest debt, and a lack of recent growth, it would seem the market is expecting improvement in earnings.
