Use our scanner to monitor DFIS 30 day historical volatility alongside longer lookback windows and spot the moments when realized and implied diverge.
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 DFIS 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Dimensional International Small Cap 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 Portfolio, using a market capitalization weighted approach, is designed to purchase securities of small, non-U.S. companies in countries with developed markets. The Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the small-cap segment of developed non-U.S. markets.
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 Dimensional International Small Cap ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where DFIS HV is running hot, cold, or in line. Make the DFIS 30 day historical volatility — and every other window — work for your edge instead of against it.
