Price-to-Earnings Ratio (P/E)

What is Price-to-Earnings Ratio?

A company's share price divided by its earnings per share.

Understanding Price-to-Earnings Ratio

The P/E ratio shows how much investors pay for each dollar of earnings. A high P/E can mean expected growth or overvaluation.

Compare P/E ratios within the same industry; typical levels differ a lot between sectors.

Formula

P/E=Price per shareEarnings per share\text{P/E} = \frac{\text{Price per share}}{\text{Earnings per share}}

Example

A $60 stock with EPS of $3 has a P/E of 20.
