Understanding P/E Ratio: A Beginner's Guide to Stock Valuation

What is the P/E Ratio?

The Price-to-Earnings (P/E) ratio is a fundamental valuation metric that helps investors understand how much they're paying for each dollar of a company's earnings.

Formula: P/E Ratio = Stock Price / Earnings Per Share (EPS)

Types of P/E Ratios

Uses past 12 months of earnings. More reliable as it's based on actual data.

Forward P/E

Uses projected future earnings. Useful for growth companies but involves estimation risk.
