How the simulator works
Each hedge is a set of one-year European options on the chosen benchmark, entered at the start of the year and held to the end. Option values are estimated with the Black-Scholes model using a 3.5% interest rate, a dividend yield of 1.3% for the S&P 500 and 0.7% for the Nasdaq-100, and a skew adjustment that raises implied volatility for lower strikes.
In the stress test, the market path is stylized and set by the user, and implied volatility starts at the level shown and rises as the market falls.
In the history replay, the market is SPY (S&P 500) or QQQ (Nasdaq-100) with dividends reinvested, and implied volatility on each day is taken from the VIX or VXN closing level. Before VXN data begins in January 2001, Nasdaq-100 volatility is estimated as 1.35 times the VIX. Historical data runs from January 3, 2000 to October 30, 2026 and is updated periodically.
