To keep it practical, we'll show how Aperam S.A.'s (AMS:APAM) P/E ratio could help you assess the value on offer. Looking at earnings over the last twelve months, Aperam has a P/E ratio of 13.88. In other words, at today's prices, investors are paying â‚¬13.88 for every â‚¬1 in prior year profit.

### How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for Aperam:

P/E of 13.88 = â‚¬28.40 Ã· â‚¬2.05 (Based on the year 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. 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 Aperam 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. As you can see below, Aperam has a higher P/E than the average company (10.1) in the metals and mining industry.

Aperam'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

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. That means unless the share price falls, the P/E will increase in a few years. A higher P/E should indicate the stock is expensive relative to others -- and that may encourage shareholders to sell.

Aperam saw earnings per share decrease by 47% last year. But EPS is up 43% over the last 5 years. And it has shrunk its earnings per share by 1.6% per year over the last three years. This might lead to low expectations.

### Remember: P/E Ratios Don't Consider The Balance Sheet

Don't forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. 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).

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

### So What Does Aperam's Balance Sheet Tell Us?

Net debt totals just 6.2% of Aperam's market cap. So it doesn't have as many options as it would with net cash, but its debt would not have much of an impact on its P/E ratio.

### The Verdict On Aperam's P/E Ratio

Aperam has a P/E of 13.9. That's below the average in the NL market, which is 20.6. With only modest debt, it's likely the lack of EPS growth at least partially explains the pessimism implied by the P/E ratio.
