Stock splits: making expensive shares accessible

When a stock gets too expensive, companies divide each share into multiple smaller shares. Mostly cosmetic, but worth understanding.

A stock split happens when a company increases the number of its outstanding shares by dividing each existing share into multiple new ones. A 2-for-1 split turns one $400 share into two $200 shares. The total value you own doesn't change.

Why companies do it

  • Make the share price look more affordable to small investors
  • Improve trading liquidity
  • Stay below psychological barriers like $1,000 per share

Reverse splits

The opposite. A 1-for-10 reverse split turns ten $1 shares into one $10 share. Companies do this when their stock has fallen so low it risks being delisted from major exchanges (which often require shares to trade above $1). Reverse splits are usually a warning sign, not a celebration.

Watch out

Stock splits don't make a company more valuable. The financial press loves to cover them, but they're cosmetic. Don't change your investment thesis based on a split.

What this lesson is NOT

A split changes the number of shares and the price per share, but the total value you own does not change. This lesson explains why a split is mostly cosmetic; it is not a signal to buy or a sign that a company has become more valuable.
