Options

Options pages focus on contracts that create rights without creating the same obligation on the buyer. That makes them useful for speculation, hedging, and payoff structures that are hard to build with cash instruments alone.

Use Core Option Contracts, Calls, and Puts for the basic contract vocabulary, Moneyness, Strikes, and Expiration for exercise economics, Spreads, Combinations, and Payoff Strategies for multi-leg structures, and Volatility, Greeks, and Option Sentiment for sensitivity and pricing language.
