Liquidity — Why It Is Life and Death
The invisible factor
Liquidity = how much you can trade without moving the price. It shows up in three places: tight spreads, deep order books, and high volume. Liquid markets forgive mistakes; illiquid markets execute them. In a crisis, liquidity evaporates first — everyone wants out, nobody bids, and prices gap.
Liquidity hierarchy
Roughly: mega-cap stocks and Treasury bonds (deepest) → large-caps → ETFs → mid-caps → small-caps → micro-caps → private assets (you can't sell at all). Notice what is missing from this course's early lessons: anything illiquid. That is deliberate — learn to walk on pavement before ice.
The liquidity premium
Illiquid assets must offer higher expected returns to compensate — that is the liquidity premium. It is real compensation, but it is only collectible if you can truly hold through pain without being forced to sell. Never put money in illiquid things that you might need next year.
What you'll practise
You need to sell a small-cap position worth $50,000. Average daily volume: 40,000 shares; price $5; the position is 10,000 shares (25% of a full day's volume). What is the smartest execution?
