This is a measure of the annualized standard deviation of logarithmic returns of an asset over a lookback period, providing a quantifiable measure of past price dispersion. It is derived directly from historical price data points, typically using daily or intra-day observations. This backward-looking figure serves as a baseline input for volatility modeling.
Horizon
The specific time window selected for the calculation significantly impacts the resulting value, as market dynamics change over different durations. Short horizons capture recent market shocks, while longer horizons smooth out transient noise to reflect a more stable risk profile. Prudent risk management requires evaluating this measure across multiple time frames.
Analysis
Comparing this measure against the implied volatility derived from option prices reveals the market’s expectation premium or discount relative to past realized movement. A significant term structure difference suggests the market anticipates a change in the asset’s risk profile. This comparison is fundamental to relative value trading in the derivatives space.
