Historical volatility is the annualized standard deviation of an underlying's past returns, typically measured over rolling windows like 10, 20, 30, or 60 days. The KDEF 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing PLUS Korea Defense Industry Index ETF's HV to its implied volatility reveals the volatility risk premium — when IV sits well above HV, option sellers tend to have an edge; when HV runs hot relative to IV, buyers may be underpaying for movement.
