What is Notional Value?

Notional Value The total underlying value controlled by an options position. For one equity option contract, notional value equals the stock price times 100 shares. A single AAPL option at $150 controls $15,000 of notional value. Understanding notional exposure helps assess the true scale of risk, especially for leveraged positions.
