The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We’ll apply a basic P/E ratio analysis to Apergy Corporation’s (NYSE:APY), to help you decide if the stock is worth further research. What is Apergy’s P/E ratio? Well, based on the last twelve months it is 26.38. That means that at current prices, buyers pay \$26.38 for every \$1 in trailing yearly profits.

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

The formula for price to earnings is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for Apergy:

P/E of 26.38 = \$31.47 ÷ \$1.19 (Based on the year to March 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 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. That means unless the share price increases, the P/E will reduce in a few years. Then, a lower P/E should attract more buyers, pushing the share price up.

Apergy saw earnings per share decrease by 25% last year. But over the longer term (5 years) earnings per share have increased by 12%.

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

We can get an indication of market expectations by looking at the P/E ratio. As you can see below, Apergy has a higher P/E than the average company (18.6) in the energy services industry.

Apergy’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 investors should delve deeper. I like to check if company insiders have been buying or selling.

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

It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. 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.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### How Does Apergy’s Debt Impact Its P/E Ratio?

Apergy’s net debt equates to 25% of its market capitalization. While it’s worth keeping this in mind, it isn’t a worry.

### The Bottom Line On Apergy’s P/E Ratio

Apergy trades on a P/E ratio of 26.4, which is above the US market average of 17.9. With some debt but no EPS growth last year, the market has high expectations of future profits.
