Stock Split

A stock split divides existing shares into more shares at a proportionally lower price. A 2-for-1 split turns 100 shares at $200 into 200 shares at $100. Total value is unchanged.

In more depth

Stock splits don't change the fundamental value of a holding — you have more shares worth less each. For dividend investors, a stock split typically means a proportionally lower per-share dividend, though the total dollar income from the position remains the same.

How splits work for dividend investors

Assume you own 100 shares of a stock at $200, with a $4 quarterly dividend ($1,600 annual income from this position). The company announces a 4-for-1 stock split.

After split: 400 shares at $50. Quarterly dividend is now $1.00 per share (4× more shares, ¼ the per-share amount). Annual income from the position: still $1,600.

The economics are identical. Only the per-share numbers change.

Why splits happen

Companies typically split shares when the stock price rises high enough that the per-share price creates a psychological or practical barrier for some investors. Amazon splitting 20-for-1 in 2022 took a $3,000+ stock to around $150, making it more accessible for smaller investors and enabling inclusion in price-weighted indices.

What to watch for after a split

Some companies adjust their dividend per share precisely for the split (preserving total income). Others use the split as an opportunity to make a larger per-share adjustment — effectively raising or lowering total income. Always recalculate your expected annual income after a split announcement.
