A stock split is when a company increases the number of its outstanding shares by dividing each existing share, while lowering the price per share proportionally.
The total value of your investment stays the same - it’s just cut into more (or fewer) pieces.

Let’s say you own 100 shares of XYZ stock at $50 per share, and the company announces a 2-for-1 split.
Step-by-step:
- Shares: 100
- Price: $50
- Split Ratio: 2-for-1
Calculations:
- New shares: 100 x (2/1) = 200 shares
- New price: $50 / 2 = $25
- Total value: 200 x $25 = $5,000 (no change)

Does a stock split change the value of my investment?
No, it just changes how many shares you own and what each one is worth. Your total value stays the same.
Why do companies do stock splits?
Usually to make their stock price more accessible to everyday investors, or to signal growth and confidence.
What’s a reverse split?
The opposite of a stock split. You end up with fewer shares at a higher price. It’s often used to lift a stock price above listing minimums.
