Index Options
Definition
Index options are financial derivatives that provide the right, but not the obligation, to buy or sell an index of stocks at a predetermined price before or at expiration. These options can be traded on various exchanges, including the New York Stock Exchange (NYSE), American Stock Exchange (AMEX), and the Chicago Board Options Exchange (CBOE). By using index options, investors can efficiently gain exposure to a broad market or specific industry group without having to purchase each individual stock within the index.
Examples
- S&P 500 Index Options (SPX): Options based on the S&P 500 Index, offering broad market exposure.
- Nasdaq-100 Index Options (NDX): Options on the Nasdaq-100 Index, which includes 100 of the largest non-financial companies listed on Nasdaq.
- Russell 2000 Index Options (RUT): Options on the Russell 2000 Index, which tracks 2000 small-cap companies.
