Group 1: Volatility Index Explanation - The implied volatility index of financial options reflects the 30 - day implied volatility trend as of the previous trading day. The implied volatility index of commodity options is obtained by weighting the implied volatilities of the two - strike options above and below the at - the - money option of the main contract month, reflecting the implied volatility change trend of the main contract [1] - The difference between the implied volatility index and historical volatility indicates the relative level of implied volatility compared to historical volatility. A larger difference means the implied volatility is relatively higher, and a smaller difference means it is relatively lower [1] Group 2: Implied Volatility Quantile Explanation - The implied volatility quantile represents the current level of a variety's implied volatility in history. A high quantile means the current implied volatility is high, and a low quantile means it is low [3] - Volatility spread is the implied volatility index minus historical volatility [3]

Group 1: Implied Volatility Index and Historical Volatility - The financial option implied volatility index reflects the 30 - day implied volatility trend as of the previous trading day, and the commodity option implied volatility index is obtained by weighting the implied volatility of the two - level options above and below the at - the - money option of the main contract month, reflecting the implied volatility change trend of the main contract [3] - The difference between the implied volatility index and historical volatility indicates the relative level of implied volatility to historical volatility. A larger difference means the implied volatility is relatively higher, and a smaller difference means it is relatively lower [3] Group 2: Implied Volatility Quantile and Volatility Spread - The implied volatility quantile represents the current level of the implied volatility of a variety in history. A high quantile means the current implied volatility is high, and a low quantile means it is low [5] - The volatility spread is related to the implied volatility index and historical volatility [5] Group 3: Implied Volatility Quantile Data - Implied volatility quantile data is presented for various items such as 500E, 50E, 1000 ta za, 300 index, and rebar [7]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - On February 3, 2026, all stock indices fluctuated and rose. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.5656 trillion yuan, a decrease of 41 billion yuan from the previous day. As gold and commodity prices stabilized, the resource cycle sector rebounded, and the risk appetite of the stock market recovered. This rebound was a technical correction of the previous over - decline caused by the weakening of risk appetite in the stock market due to the sharp correction in the commodity market. Currently, the trading volume in the stock market remains in a shrinking state, indicating that the upward driving force of the stock market is still weak. Due to the weakening of macro - economic indicators and the fact that the increase in this stock rebound is mainly contributed by the valuation side, the willingness of investors in the capital market to take profits has increased, and it is difficult for the capital side to form a consistent force in the short term. However, in the long - term, the positive policy expectations and the continuous net inflow of incremental funds into the stock market remain unchanged, and the logic of the long - term upward movement of stock indices is relatively solid. In general, the risk appetite of the stock market is cautiously optimistic in the short term, and stock indices will mainly fluctuate and consolidate. For options, considering the relatively solid long - term upward logic of stock indices, a bull spread strategy can be adopted [3]. 3.
