# Here's How P/E Ratios Can Help Us Understand HollyFrontier Corporation (NYSE:HFC)

The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). To keep it practical, we'll show how HollyFrontier Corporation's (NYSE:HFC) P/E ratio could help you assess the value on offer. Looking at earnings over the last twelve months, HollyFrontier has a P/E ratio of 9.48. That means that at current prices, buyers pay \$9.48 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 Ã· Earnings per Share (EPS)

Or for HollyFrontier:

P/E of 9.48 = \$51.38 Ã· \$5.42 (Based on the trailing twelve months to June 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. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

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

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. You can see in the image below that the average P/E (9.9) for companies in the oil and gas industry is roughly the same as HollyFrontier's P/E.

That indicates that the market expects HollyFrontier will perform roughly in line with other companies in its industry. So if HollyFrontier actually outperforms its peers going forward, that should be a positive for the share price. Checking factors such as director buying and selling. could help you form your own view on if that will happen.

### 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. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

HollyFrontier saw earnings per share decrease by 32% last year. But EPS is up 18% over the last 5 years.

### Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

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. 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).

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 HollyFrontier's P/E?

Net debt totals 18% of HollyFrontier's market cap. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

### The Verdict On HollyFrontier's P/E Ratio

HollyFrontier's P/E is 9.5 which is below average (18.2) in the US market. Since it only carries a modest debt load, it's likely the low expectations implied by the P/E ratio arise from the lack of recent earnings growth.

Investors have an opportunity when market expectations about a stock are wrong. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
