Today, we’ll introduce the concept of the P/E ratio for those who are learning about investing. To keep it practical, we’ll show how Preformed Line Products Company’s (NASDAQ:PLPC) P/E ratio could help you assess the value on offer. Looking at earnings over the last twelve months, Preformed Line Products has a P/E ratio of 10.95. In other words, at today’s prices, investors are paying \$10.95 for every \$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 ÷ Earnings per Share (EPS)

Or for Preformed Line Products:

P/E of 10.95 = \$49.8 ÷ \$4.55 (Based on the year to March 2019.)

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

A higher P/E ratio means that investors are paying a higher price for each \$1 of company earnings. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.’

### How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. When earnings grow, the ‘E’ increases, over time. And in that case, the P/E ratio itself will drop rather quickly. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Preformed Line Products increased earnings per share by a whopping 39% last year. And earnings per share have improved by 5.8% annually, over the last five years. I’d therefore be a little surprised if its P/E ratio was not relatively high.

### Does Preformed Line Products Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. If you look at the image below, you can see Preformed Line Products has a lower P/E than the average (16.1) in the electrical industry classification.

This suggests that market participants think Preformed Line Products will underperform other companies in its industry. Many investors like to buy stocks when the market is pessimistic about their prospects. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

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

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

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.

### Is Debt Impacting Preformed Line Products’s P/E?

Preformed Line Products has net debt worth just 2.1% of its market capitalization. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

### The Verdict On Preformed Line Products’s P/E Ratio

Preformed Line Products has a P/E of 11. That’s below the average in the US market, which is 17.5. The company hasn’t stretched its balance sheet, and earnings growth was good last year. If the company can continue to grow earnings, then the current P/E may be unjustifiably low.
