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

The formula for P/E is:

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

Or for ams:

P/E of 45.40 = CHF40.18 (Note: this is the share price in the reporting currency, namely, EUR ) Ã· CHF0.89 (Based on the year to June 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. 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.

### Does ams Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. The image below shows that ams has a higher P/E than the average (24.4) P/E for companies in the semiconductor industry.

Its relatively high P/E ratio indicates that ams 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 delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

If earnings fall then in the future the 'E' will be lower. 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.

ams's earnings per share fell by 55% in the last twelve months. And EPS is down 5.4% a year, over the last 5 years. This growth rate might warrant a below average P/E ratio.

### Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

Don't forget that the P/E ratio considers market capitalization. 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 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.

### ams's Balance Sheet

ams has net debt equal to 37% of its market cap. You'd want to be aware of this fact, but it doesn't bother us.

### The Bottom Line On ams's P/E Ratio

ams's P/E is 45.4 which is above average (18.7) in its market. With modest debt but no EPS growth in the last year, it's fair to say the P/E implies some optimism about future earnings, from the market.
