Small Companies vs Giant Companies

How big a company is changes how its stock tends to behave.

The idea

Companies come in wildly different sizes, and investors measure size with market cap: the price of one share multiplied by how many shares exist. A small company can grow quickly, but its share price often swings up and down more sharply. A giant company usually moves more slowly and tends to be steadier, though it can still lose value. Neither size is automatically better — they just behave differently, which is why many investors hold a mix. 🌱

Words to know

Share
One small piece of a company that you can own.
Market cap
The price of one share times the number of shares. It is a way of saying how big a company is.
Small-cap
A company with a small market cap, usually a business you may never have heard of.
Large-cap
A company with a very big market cap, often a brand you already know.
Volatile
A price that jumps up and down a lot instead of moving gently.
