Core Viewpoint - The market's significant increase in volume indicates a strong positive sentiment among investors, while the sharp rise in implied volatility signals a quick escalation in speculative activity [1] Market Dynamics - If the market and implied volatility continue to rise rapidly, a short-term adjustment may occur as the market returns to rationality [1] - Conversely, if the market maintains a "slow bull" trend with stable or significantly declining implied volatility, the timing of market fluctuations may be delayed compared to the previous scenario [1] Long-term Logic - The three key long-term drivers of the bull market remain robust: stable market policies, a focus on technology, and the narrative against internal competition [1] - This suggests that as long as these long-term drivers remain unchanged, any market adjustments should be viewed as opportunities, and the bullish mindset should be maintained [1]

Group 1: Implied Volatility Index and Historical Volatility - The financial option implied volatility index reflects the 30 - day implied volatility (IV) trend as of the previous trading day. The commodity option implied volatility index 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 IV 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: Implied Volatility Index and Volatility Spread Quantile Ranking - Implied volatility quantile represents 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 IV minus HV [4] - The implied volatility quantile rankings of some varieties are as follows: 300 Index (0.83), China Securities (0.84), PTA (0.80), 5 - year (0.43), 50ETF (0.39), PVC (0.38), etc. The historical volatility quantile rankings of some varieties are also presented, such as PTA (0.27) [4][5]
