What is Liquidity?
Liquidity refers to how easily a security can be bought or sold without significantly affecting its price. Highly liquid stocks have many buyers and sellers and tight bid-ask spreads.
Liquidity Explained
Liquidity is crucial for traders because it determines how easily you can enter and exit positions. Large-cap stocks like AAPL and MSFT are extremely liquid — you can trade millions of dollars worth in seconds. Small-cap stocks may have very low liquidity, meaning large orders can move the price significantly. Illiquid stocks often have wider spreads and more slippage.
Real-World Example
AAPL trades 70 million shares per day with a $0.01 spread — extremely liquid. A microcap stock trades only 50,000 shares per day with a $0.50 spread. Buying $100,000 of AAPL barely moves the price. Buying $100,000 of the microcap could push the price up 5% just from your order.
