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 PWRD 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing TCW Transform Systems 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.

PWRD is a concentrated stock portfolio of companies perceived to drive and benefit from the energy transition to net zero carbon emissions. Using a proprietary framework, the fund screens the broad US equity market to select companies with a strategy to reduce or enable decarbonization at scale. Selection combines a top-down analysis of the economy with a bottom-up, industry-by-industry, and company-by-company assessment. The adviser does not use sustainability ratings or rankings to exclude companies or sectors. As a result, the portfolio may focus on the most carbon-intensive industries in order for the adviser to drive change through its proxy voting guidelines.

Such guidelines encourage companies to invest in their employees, communities, customers, and the environment. The adviser has discretion to target specific investment opportunities. Prior to October 13, 2023, the fund was called the Engine No. 1 Transform Climate ETF. Prior to Feb. 3, 2025, the fund had a ticker of NETZ.

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