Liquidity
Liquidity is how quickly and easily an asset can be converted to cash without losing value in the process.
Cash is perfectly liquid; publicly traded stocks and funds settle in a day or two; a house or a stake in a small business may take months and a price concession to sell. Retirement accounts add a second layer — the assets inside may be liquid while penalties make the account itself expensive to tap early.
Why it matters in practice
Liquidity failures are how sound long-term plans break: an emergency arrives, nothing liquid is available, and long-term investments get sold at a bad moment or retirement accounts raided at tax cost. An emergency fund is, at bottom, a liquidity reserve that lets the rest of the portfolio stay invested. Illiquid assets often must offer higher expected returns to be worth holding — a premium worth collecting only with money that will not be needed soon.
