Portfolio Risk Assessment involves the quantitative evaluation of the aggregate exposure across a collection of financial instruments, including spot assets and various derivatives like options and futures. This process moves beyond simple asset value to measure potential loss under adverse market scenarios. Key metrics derived include Value at Risk and Expected Shortfall.
Metric
The selection of appropriate risk metrics is crucial for translating complex derivative positions into comparable measures of potential drawdown. Calculating the portfolio’s overall Delta, Gamma, and Vega sensitivities provides a multi-dimensional view of market exposure.
Exposure
Assessing the net exposure requires aggregating the directional and volatility sensitivities from all positions, accounting for the non-linear payoff structures inherent in options. This analysis informs capital allocation decisions and the necessity for active hedging programs.
