### 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 American Superconductor:

P/E of 35.27 = \$7.87 ÷ \$0.22 (Based on the trailing twelve months to September 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. 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.

### How Does American Superconductor's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. As you can see below, American Superconductor has a higher P/E than the average company (18.2) in the electrical industry.

American Superconductor's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isn't guaranteed. So further research is always essential. I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. Earnings growth means that in the future the 'E' will be higher. That means even if the current P/E is high, it will reduce over time if the share price stays flat. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

American Superconductor saw earnings per share decrease by 41% last year.

### 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. That means it doesn't take debt or cash into account. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

### Is Debt Impacting American Superconductor's P/E?

With net cash of US\$53m, American Superconductor has a very strong balance sheet, which may be important for its business. Having said that, at 31% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Verdict On American Superconductor's P/E Ratio

American Superconductor's P/E is 35.3 which is above average (18.5) in its market. Falling earnings per share is probably keeping traditional value investors away, but the healthy balance sheet means the company retains potential for future growth. If fails to eventuate, the current high P/E could prove to be temporary, as the share price falls.

Investors have an opportunity when market expectations about a stock are wrong.
