### How Do I Calculate Genmab's Price To Earnings Ratio?

The formula for P/E is:

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

Or for Genmab:

P/E of 70.11 = DKK1336.50 Ã· DKK19.06 (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 DKK1 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 Does Genmab's P/E Ratio Compare To Its Peers?

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 (32.6) for companies in the biotechs industry is lower than Genmab's P/E.

That means that the market expects Genmab will outperform other companies in its industry. The market is optimistic about the future, but that doesn't guarantee future growth. So investors should delve deeper. I like to check if company insiders have been buying or 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. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. Then, a lower P/E should attract more buyers, pushing the share price up.

Genmab's earnings per share fell by 6.1% in the last twelve months. But it has grown its earnings per share by 49% per year over the last five years.

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

The 'Price' in P/E reflects the market capitalization of the company. 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.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

### So What Does Genmab's Balance Sheet Tell Us?

The extra options and safety that comes with Genmab's Ã¸7.0b net cash position means that it deserves a higher P/E than it would if it had a lot of net debt.

### The Bottom Line On Genmab's P/E Ratio

With a P/E ratio of 70.1, Genmab is expected to grow earnings very strongly in the years to come. The recent drop in earnings per share might keep 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.
