What have we learned about the P/E ratio? Although the P/E often doesn't tell us much, it can be useful to compare the P/E of one company to another in the same industry, to the market in general, or to the company's own historical P/E ratios.

Some points to remember:

  • The P/E ratio is the current stock price of a company divided by its earnings per share (EPS).
  • Variations exist using trailing EPS, forward EPS, or an average of the two.
  • Historically, the average P/E ratio in the market has been around 15-25.
  • Theoretically, a stock's P/E tells us how much investors are willing to pay per dollar of earnings.
  • A better interpretation of the P/E ratio is to see it as a reflection of the market's optimism concerning a firm's growth prospects.
  • The P/E ratio is a much better indicator of a stock's value than the market price alone.
  • In general, it's difficult to say whether a particular P/E is high or low without taking into account growth rates and the industry.
  • Changes in accounting rules as well as differing EPS calculations can make analysis difficult.
  • P/E ratios are generally lower during times of high inflation.
  • There are many explanations as to why a company has a low P/E.
  • Don't base any buy or sell decision on the multiple alone.
