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 Amgen Inc.'s (NASDAQ:AMGN), to help you decide if the stock is worth further research. Amgen has a P/E ratio of 15.38, based on the last twelve months. That corresponds to an earnings yield of approximately 6.5%.
How Do I Calculate Amgen's Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for Amgen:
P/E of 15.38 = $195.04 ÷ $12.68 (Based on the trailing twelve months to June 2019.)
Is A High Price-to-Earnings Ratio Good?
The higher the P/E ratio, the higher the price tag of a business, relative to its trailing 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 Amgen 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. If you look at the image below, you can see Amgen has a lower P/E than the average (19) in the biotechs industry classification.
This suggests that market participants think Amgen will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.
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. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.
Amgen's earnings made like a rocket, taking off 278% last year. Having said that, if we look back three years, EPS growth has averaged a comparatively less impressive 8.8%.
Remember: P/E Ratios Don't Consider The Balance Sheet
Don't forget that the P/E ratio considers market capitalization. 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).
While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.
How Does Amgen's Debt Impact Its P/E Ratio?
Amgen has net debt worth just 7.6% 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 Bottom Line On Amgen's P/E Ratio
Amgen trades on a P/E ratio of 15.4, which is below the US market average of 18. The company does have a little debt, and EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified.
