Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each €1 the company has earned over the last year. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.

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. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

L'Air Liquide S.A's earnings per share fell by 8.2% in the last twelve months. But it has grown its earnings per share by 2.8% per year over the last five years.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

Don't forget that the P/E ratio considers market capitalization. In other words, it does not consider any debt or cash that the company may have on the balance sheet. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

Is Debt Impacting L'Air Liquide S.A's P/E?

L'Air Liquide S.A's net debt equates to 27% of its market capitalization. While that's enough to warrant consideration, it doesn't really concern us.

The Verdict On L'Air Liquide S.A's P/E Ratio

L'Air Liquide S.A's P/E is 26.3 which is above average (17.1) in its market. With a bit of debt, but a lack of recent growth, it's safe to say the market is expecting improved profit performance from the company, in the next few years.
