Portfolio Sensitivity Analysis
Portfolio sensitivity analysis is the systematic evaluation of how a portfolio value changes in response to variations in underlying market variables. This includes analyzing the impact of price changes, volatility shifts, interest rate fluctuations, and the passage of time on the portfolio Greeks.
By performing this analysis, traders can identify potential vulnerabilities and assess the effectiveness of their hedging strategies. This process often involves stress testing the portfolio against extreme market scenarios to ensure it can withstand periods of high volatility or liquidity crunches.
Sensitivity analysis is a cornerstone of risk management, providing the insights needed to make informed decisions about position sizing and hedge adjustments. It helps traders understand the interconnected nature of their risks and how different factors might compound during market stress.
A well managed portfolio is one that is continuously subjected to rigorous sensitivity analysis.
