PortfolioDeltaExposure quantifies the aggregate sensitivity of an entire investment portfolio to changes in the price of its underlying assets, expressed as a single delta value. It represents the approximate change in portfolio value for a unit change in the underlying asset’s price.
Mechanism
This exposure is calculated by summing the individual delta values of all positions within the portfolio, where each position’s delta is weighted by its size. For crypto options, delta measures the rate of change of the option’s price relative to a change in the underlying cryptocurrency’s price, with positive deltas indicating long exposure and negative deltas indicating short exposure.
Methodology
Managing PortfolioDeltaExposure is a core tenet of risk management and hedging strategies for institutional traders in crypto options. By actively monitoring and adjusting this aggregate delta, portfolio managers can maintain a neutral market posture (delta hedging), take specific directional bets, or manage their overall market sensitivity to align with specific risk tolerances and investment objectives.
