What Is a PE Ratio?
The Price-to-Earnings (P/E) Ratio measures the relationship between a company’s current share price and its earnings per share (EPS).
It answers a simple question:
How much are investors paying for every $1 of a company’s earnings?
A higher P/E ratio often suggests investors expect higher future growth, while a lower P/E ratio may indicate a stock is undervalued—or that the market expects slower growth.
PE Ratio Formula
P/E Ratio = Market Price per Share ÷ Earnings Per Share (EPS)
