Stock Splits
When companies divide shares to lower the price per share.
Quick Answer
A stock split increases the number of shares while proportionally decreasing the price. A 4-for-1 split means each share becomes 4 shares at 1/4 the price. Splits don't change company value but can increase accessibility and signal management confidence.

What It Is
A stock split divides existing shares into more shares at a proportionally lower price. A 10-for-1 split turns 1 share at $1000 into 10 shares at $100 each. Total value unchanged—you just have more shares at a lower price.
