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 SMLL 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Harbor Active 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.

SMLL focuses on long-term total return through investments in US small capitalization companies that fall within the Russell 2000 Index. Employing a proprietary bottom-up analysis, SMLL selects approximately 30 to 80 companies based on competitive advantages, strong business models, and consistent cash flow. The selection process involves metrics like Price to Free Cash Flow, Return on Invested Capital, and insider share purchases. The Fund also analyzes a companys competitive position and assesses management's ability to allocate capital effectively. Regular valuation analysis is conducted to determine a stock's intrinsic value and assess whether it is trading at a discount.

SMLL may divest from certain holdings if there are shifts in fundamentals, market overvaluation, or when better investment opportunities arise.

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