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 SPD 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Simplify US Equity PLUS Downside Convexity 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.
The Simplify US Equity PLUS Downside Convexity ETF (SPD) seeks to provide capital appreciation by offering US large cap exposure while aiming to boost performance during extreme market moves down via an options overlay. The fund's core holding gives investors a low-cost, index-based exposure to US large caps. A modest option overlay budget is then deployed into a series of options positions that help create downside convexity in the fund.
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 Simplify US Equity PLUS Downside Convexity ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where SPD HV is running hot, cold, or in line.
