Group 1: Volatility Index Explanation - The implied volatility index of financial options reflects the 30 - day implied volatility (IV) trend as of the previous trading day. The implied volatility index of commodity options is obtained by weighting the IV of the two - strike options above and below the at - the - money option of the main contract, reflecting the IV change trend of the main contract [2] - The difference between the implied volatility index and historical volatility (HV) indicates the relative level of IV to HV. A larger difference means higher IV relative to HV, and a smaller difference means lower IV relative to HV [2] Group 2: Volatility Data Graphs - There are graphs showing the IV, HV, and IV - HV differences of various financial and commodity options, including 300 - stock index, 50ETF, 1000 - stock index, 500ETF, silver, soybean meal, corn, sugar, cotton, methanol, rubber, iron ore, PTA, crude oil, copper, aluminum, PVC, rebar, zinc, urea, soybean oil, palm oil, and rapeseed oil [3] Group 3: Implied Volatility and Historical Volatility Quantile Ranking - Implied volatility quantiles represent the current level of a variety's IV in history. A high quantile means the current IV is high, and a low quantile means the current IV is low. Volatility spread is the difference between the implied volatility index and historical volatility [4] - The implied volatility and historical volatility quantile rankings of various commodities such as PVC, PTA, iron ore, cotton, 50ETF, 300 - stock index are presented, with specific quantile values provided [5]

Group 1: Implied Volatility Index and Historical Volatility - The financial options implied volatility index reflects the 30 - day implied volatility (IV) trend as of the previous trading day.
