What Is Liquidity?
Liquidity describes how easily something can be bought or sold without moving its price sharply.
The simple explanation
Liquidity describes how easily something can be bought or sold without moving its price sharply.
Why it matters
It affects spreads, slippage and how easily you can exit.
A simple way to think about it
Judge liquidity using volume, spread and order-book depth. Liquidity can disappear quickly during news, halts or market stress.
A common beginner mistake
Assuming high daily volume always means your order will fill at one price.
What to check next
- Check that you understand the definition in plain English.
- Look at the company, market and timeframe rather than one number alone.
- Ask what could change the interpretation.
- Keep risk separate from excitement or certainty.
One calm takeaway
Liquidity describes how easily something can be bought or sold without moving its price sharply. Use it as one piece of context, never as a promise about what happens next.
