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 JMST 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing JPMorgan Ultra-Short Municipal Income 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.
Under normal circumstances, the fund invests at least 80% of its assets in municipal securities, the income from which is exempt from federal income tax. For purposes of this policy, "Assets" means net assets, plus the amount of borrowings for investment purposes. Up to 100% of the fund's assets may be invested in short-term municipal instruments such as variable rate demand notes, short-term municipal notes and tax-exempt commercial paper.
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 JPMorgan Ultra-Short Municipal Income ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where JMST HV is running hot, cold, or in line. Make the JMST 30 day historical volatility — and every other window — work for your edge instead of against it.
