# What Does AIXTRON SE's (FRA:AIXA) P/E Ratio Tell You?

This article is for investors who would like to improve their understanding of price to earnings ratios (P/E ratios). We'll show how you can use AIXTRON SE's (FRA:AIXA) P/E ratio to inform your assessment of the investment opportunity. AIXTRON has a P/E ratio of 22, based on the last twelve months. In other words, at today's prices, investors are paying â‚¬22 for every â‚¬1 in prior year profit.

### 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 AIXTRON:

P/E of 22 = â‚¬9.03 Ã· â‚¬0.41 (Based on the trailing twelve months to June 2019.)

### 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 is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does AIXTRON 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 AIXTRON has a P/E ratio that is roughly in line with the semiconductor industry average (22).

That indicates that the market expects AIXTRON will perform roughly in line with other companies in its industry. The company could surprise by performing better than average, in the future. I would further inform my view by checking insider buying and selling., among other things.

### How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. When earnings grow, the 'E' increases, over time. That means unless the share price increases, the P/E will reduce in a few years. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

AIXTRON shrunk earnings per share by 2.8% last year.

### 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. 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.

### How Does AIXTRON's Debt Impact Its P/E Ratio?

AIXTRON has net cash of â‚¬259m. This is fairly high at 26% of its market capitalization. That might mean balance sheet strength is important to the business, but should also help push the P/E a bit higher than it would otherwise be.

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

AIXTRON trades on a P/E ratio of 22, which is above its market average of 18.5. The recent drop in earnings per share might keep value investors away, but the relatively strong balance sheet will allow the company time to invest in growth. Clearly, the high P/E indicates shareholders think it will!
