Applied Greek Risk Management: Maintaining Greek Balance Across an Options Portfolio

A trader who manages options positions individually, without considering aggregate Greeks, is operating with incomplete information. A portfolio of individually reasonable positions can have a dangerously high aggregate gamma near expiration, a vega exposure that amplifies dramatically during a volatility spike, or a delta that has drifted far from neutral without any individual position having changed. This course develops the portfolio-level Greek awareness that separates systematic options management from trade-by-trade reaction. By the end of this course you will be able to calculate and interpret aggregate portfolio-level Greeks across a multi-position options book, identify when aggregate gamma, vega, or delta exposure has reached levels that require attention, apply a systematic Greek rebalancing process to reduce concentrated risk, use Greek monitoring as an early warning system for positions approaching their management thresholds, and design a Greek risk policy that defines acceptable ranges for each key Greek at the portfolio level. What you will learn: - Aggregating Greeks across multiple positions: building a portfolio-level Greek summary from individual position data - Portfolio delta neutralisation: identifying delta imbalance and selecting adjustment instruments - Gamma exposure management: understanding when aggregate gamma creates risk and how to reduce it without closing positions - Vega concentration: recognising when multiple positions create correlated vega exposure to the same underlying or sector - Theta as portfolio income: monitoring aggregate daily theta as a portfolio income metric and its relationship to gamma risk - Greek evolution over time: tracking how portfolio-level Greeks shift as expirations approach and positions age - Stress testing with Greeks: using delta and vega to estimate portfolio P&L under a large price move or volatility spike - Greek risk policy template: defining acceptable ranges for portfolio delta, gamma, vega, and theta The course uses extended case studies — a portfolio that accumulates excessive gamma as multiple positions approach expiration in the same week, a theta-rich portfolio whose aggregate vega becomes critically exposed during an implied volatility spike, a delta-neutral portfolio that drifts significantly directional after a large price move in one underlying. Reflection prompts ask you to reason through each rebalancing decision before reading the analysis. This course is designed for active options traders who manage multiple concurrent positions and want to develop a disciplined Greek risk management practice. Written for those who understand individual Greek concepts but have not yet formalised a portfolio-level monitoring process. This course is informational and educational and does not constitute financial or investment advice.
