Step 1: Determine a target earnings per share
for your stock. This can be achieved through reading one or more analysts' opinions (see "Investment Research: Ignore the Ratings, Read the Reports"). You can also seek out the consensus estimate for a company's earnings
. A consensus estimate is the average estimates for all analysts covering a particular stock. These estimates can be found on Yahoo! Finance's individual stock quote pages, by clicking "Analyst Estimates."
multiple for your stock. This is not a straightforward task and it will require some assumptions, but it's nevertheless possible and definitely important. So how does one determine a forward P/E
for a stock? Here are a few techniques:
- Use the company's historical P/E ratios. While P/E ratios are not static, they do tend to move around a mean (average) value. This mean P/E should provide a good grounding for this analysis. You can use TheStreet.com Ratings to provide you with historical EPS and growth rates for individual stocks.
- Compare the company's P/E with that of its industry or closest competitors. There should not be a big discrepancy amongst competitors with an industry. However, the better companies will garner a premium
multiple
to that of their lesser competitors (see "Cramer's 'Mad Money' Recap: The Pizza Connection"). - Look at alternative investments. Consider the P/E for a risk-free
investment. Let's say the five-year U.S. Treasury Note
is yielding
5%. The P/E for this note will be the 20 (1 divided by .05). If you can earn a 20 P/E on a risk-free investment, then the P/E on a riskier investment needs to be considered in the context of its relative risk. In other words, why pay more for a riskier investment than a less risky one? - Look at growth rates. This is what I refer to as the Cramer Rule. Jim Cramer states that you should never pay twice the growth rate
for a stock. By that he means that the P/E should never be more than two times the expected growth in future earnings per share (see price/earnings-to-growth ratio
). You can use this benchmark
as a rule of thumb. For example, if a company that you're invested in is expected to grow earnings at 15% next year, your forward P/E should not exceed 30 times earnings.
