Stock Splits Explained

A stock split increases or decreases the number of shares outstanding while adjusting the price proportionally. Your total investment value stays the same, but the number of shares and price per share change.

What is a Stock Split?

Basic Concept

Stock Split:

• Divides existing shares
• Into more shares
• At lower price per share
• Total value unchanged

Simple Example

2-for-1 Split:

• Before: 100 shares at $100 = $10,000
• After: 200 shares at $50 = $10,000
• Same total value
• More shares, lower price

Common Split Ratios

Forward Splits

2-for-1:
