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 TOLZ 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing ProShares DJ Brookfield Global Infrastructure 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 index consists of companies domiciled globally that qualify as "pure-play" infrastructure companies-companies whose primary business is the ownership and operation of infrastructure assets, activities that generally generate long-term stable cash flows. Under normal circumstances, the fund will invest at least 80% of its total assets in component securities. It is non-diversified.

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 ProShares DJ Brookfield Global Infrastructure ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where TOLZ HV is running hot, cold, or in line. Make the TOLZ 30 day historical volatility — and every other window — work for your edge instead of against it.
