About this metric
Volatility here is the annualized standard deviation of daily log returns — the standard risk measure traders use to size positions and set stops. A 30-day window reacts quickly to regime changes; the 365-day window shows the long-run risk baseline. Compare the by-year table against yearly returns: high-volatility years are usually the ones that move the needle in either direction.
