Tracking SMN historical volatility helps you see how much ProShares UltraShort Materials's stock price has actually moved over past periods, giving you a baseline to judge whether current option premiums are fair, cheap, or expensive.

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 SMN 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing ProShares UltraShort Materials'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.

ProShares UltraShort Materials seeks daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of the S&P Materials Select SectorSM Index.

Our scanner puts ProShares UltraShort Materials's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where SMN HV is running hot, cold, or in line. Make the SMN 30 day historical volatility — and every other window — work for your edge instead of against it.
