Summary
A solid toolkit for anyone building volatility forecasts or working with options data. You get EWMA and GARCH(1,1) implementations with proper mean reversion math, implied volatility extraction from option prices, and tools to construct volatility surfaces and term structures. The skill covers both historical forecasting (with half-life calculations and multi-step GARCH projections) and forward-looking measures like the VIX and volatility risk premium. Useful for risk management, position sizing, or any trading strategy that depends on vol estimates. The GARCH formulas are production-ready with stationarity checks, and the IV treatment handles smiles and skew correctly. If you need to compare realized versus implied vol or understand why the skew exists in equity markets, this gets you there without the academic bloat.
