Tracking OILK historical volatility helps you see how much ProShares K-1 Free Crude Oil ETF's stock price has actually moved over past periods, giving you a baseline to judge whether current option premiums are fair, cheap, or expensive. While implied volatility tells you what the market expects, ProShares K-1 Free Crude Oil ETF's HV tells you what really happened. Use our scanner to monitor OILK 30 day historical volatility alongside longer lookback windows and spot the moments when realized and implied diverge.

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 OILK 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing ProShares K-1 Free Crude Oil 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 fund invests in financial instruments that ProShare Advisors believes, in combination, should track the performance of the index. The index seeks to track the performance of three separate contract schedules for West Texas Intermediate (“WTI”) Crude Oil futures traded on NYMEX. These contract schedules are equally-weighted in the index (1/3 each) at each semi-annual reset in March and September.

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 K-1 Free Crude Oil ETF's historical volatility side-by-side with implied readings across every lookback window, so you can see exactly where OILK HV is running hot, cold, or in line. Make the OILK 30 day historical volatility — and every other window — work for your edge instead of against it.
