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 DVSP 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing WEBs SPY Defined Volatility 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.
Sizing a long premium trade, modeling a covered call, or hunting volatility arbitrage all come back to one question: how much has the stock actually moved? Our scanner puts WEBs SPY Defined Volatility ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where DVSP HV is running hot, cold, or in line. Make the DVSP 30 day historical volatility — and every other window — work for your edge instead of against it.
