Strabo Glosssary: PE Ratio

PE Ratio


The P/E ratio, or price-to-earnings ratio, is a financial metric used to assess the relative value of a company's stock by comparing its market price per share to its earnings per share (EPS). It is a widely used valuation ratio in fundamental analysis and provides insight into how the market values a company's earnings.


The P/E ratio is calculated by dividing the market price per share of a company's stock by its earnings per share (EPS). The formula is:

  P/E Ratio = Market Price per Share / Earnings per Share (EPS)

The EPS is typically based on the company's most recent financial statements, such as its annual or quarterly earnings.

Key Features

  1. Interpretation: The P/E ratio indicates how much investors are willing to pay for each dollar of earnings generated by a company. It reflects the market's expectations of the company's future growth prospects, profitability, and risk.
  2. High P/E Ratio: A high P/E ratio suggests that investors are willing to pay a premium for the company's earnings, indicating high expectations for future growth or strong market sentiment. It can be an indication of a company that is expected to have higher earnings growth or has unique competitive advantages.
  3. Low P/E Ratio: A low P/E ratio suggests that the company's stock is relatively inexpensive compared to its earnings. It may indicate that the company is undervalued by the market, or there may be concerns about its future prospects or industry conditions.
  4. Industry Comparison: P/E ratios are often compared among companies within the same industry to assess relative valuation. It helps investors determine whether a company's stock is trading at a higher or lower multiple compared to its peers.
  5. Limitations: While the P/E ratio is a commonly used valuation metric, it has limitations. It does not consider other factors such as a company's growth rate, risk profile, or the industry in which it operates. Additionally, it can be influenced by one-time events, accounting practices, or other non-recurring factors that affect earnings.
  6. Forward P/E Ratio: In addition to the trailing P/E ratio based on historical earnings, investors may also consider the forward P/E ratio, which uses estimated future earnings. The forward P/E ratio provides insights into the market's expectations for future earnings growth.

In Summary

It's important to note that the P/E ratio should not be used in isolation when making investment decisions. It should be used in conjunction with other financial and qualitative factors to assess the overall investment value and potential risks associated with a company's stock.
