Realized variance represents the historical measurement of price fluctuations for a specific financial asset over a designated observation window. Unlike implied volatility which looks forward, this metric provides an ex-post calculation derived from the summation of squared logarithmic returns. Quantitative analysts utilize these figures to confirm the accuracy of pricing models and to assess the historical risk profile of a portfolio.
Calculation
Market participants compute this value by aggregating the squares of daily or intra-day returns observed during the chosen time frame. Scaling these results requires normalization to an annualized basis, allowing for direct comparison across different asset classes or derivative instruments. Precision in this process remains vital for determining the cost of options and calibrating automated hedging systems effectively.
Application
Traders leverage realized variance to evaluate the performance of their delta-neutral strategies and to identify discrepancies between historical behavior and current market sentiment. It serves as a fundamental input for risk management frameworks that require dynamic monitoring of exposure to extreme price movements. By benchmarking this data against option premiums, investors can determine if market volatility is currently overpriced or undervalued relative to historical norms.
