Options Strategies Greeks

Options trading uses mathematical models (Greeks) to quantify risk and opportunity. Greeks: Delta (price sensitivity), Gamma (delta change), Vega (volatility sensitivity), Theta (time decay), Rho (interest rate sensitivity). Strategies: covered calls (sell upside for income), spreads (vertical, iron condor, calendar), straddles (bet on volatility), collars (downside protection). Professional traders use Greeks to size positions, hedge risk, and optimize returns.
