Liquidity

A definition of liquidity and why it affects execution quality and risk.

Plain-English definition

Liquidity is the ability to buy or sell an asset without moving its price too much.

Why it matters

Liquidity influences spreads, slippage, and the reliability of price discovery.

Beginner example

A highly liquid ETF usually has tighter spreads than a thinly traded small-cap stock.

Common misunderstanding

Liquidity is not just about whether something trades. It is about how easily it trades at a fair price.
