Price-to-Earnings Ratio
Understand how much investors are paying for each dollar of earnings.
In Simple Terms
The price-to-earnings ratio, or P/E, is generally calculated by dividing share price by earnings per share.
A Simple Example
A $100 share price divided by $5 of EPS produces a P/E of 20.
Why It Matters
It helps compare valuations across similar companies or through time, but earnings quality still matters.
How to Interpret It
Interpret P/E alongside growth, industry, profit stability, interest rates, and market expectations.
Common Misunderstanding
A high P/E is not automatically overvalued, and a low P/E is not automatically cheap.
Risk Note
When earnings are negative or unusually volatile, P/E may be unavailable or misleading.
