This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We'll look at CompX International Inc.'s (NYSEMKT:CIX) P/E ratio and reflect on what it tells us about the company's share price. Looking at earnings over the last twelve months, CompX International has a P/E ratio of 12.73. That means that at current prices, buyers pay \$12.73 for every \$1 in trailing yearly profits.

### How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Price per Share Ã· Earnings per Share (EPS)

Or for CompX International:

P/E of 12.73 = \$15.69 Ã· \$1.23 (Based on the year to December 2018.)

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

### How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. 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. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Most would be impressed by CompX International earnings growth of 16% in the last year. And it has bolstered its earnings per share by 20% per year over the last five years. This could arguably justify a relatively high P/E ratio.

### Does CompX International 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 CompX International has a lower P/E than the average (23.2) P/E for companies in the commercial services industry.

This suggests that market participants think CompX International will underperform other companies in its industry. Since the market seems unimpressed with CompX International, it's quite possible it could surprise on the upside. 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

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. That means it doesn't take debt or cash into account. 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.

### Is Debt Impacting CompX International's P/E?

With net cash of US\$45m, CompX International has a very strong balance sheet, which may be important for its business. Having said that, at 23% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Verdict On CompX International's P/E Ratio

CompX International has a P/E of 12.7. That's below the average in the US market, which is 18.3. It grew its EPS nicely over the last year, and the healthy balance sheet implies there is more potential for growth. One might conclude that the market is a bit pessimistic, given the low P/E ratio.

When the market is wrong about a stock, it gives savvy investors an opportunity.
