VIX普涨至70%分位，大盘尾部风险预期升高

• The report introduces the Cinda-VIX volatility index, which reflects investors' expectations of future volatility in the options market. The index is based on methodologies from international practices and adjusted for the characteristics of China's options market. It includes a term structure to capture volatility expectations across different time horizons. As of October 17, 2025, the 30-day Cinda-VIX values for major indices are: 22.97 for SSE 50, 24.07 for CSI 300, 35.47 for CSI 500, and 30.70 for CSI 1000[61][62][63] - The report also discusses the Cinda-SKEW index, which measures the skewness of implied volatility across different strike prices of options. This index helps investors understand market expectations regarding the distribution of future returns and potential tail risks. Higher SKEW values indicate increased concerns about significant market downturns. As of October 17, 2025, the SKEW values for major indices are: 103.13 for SSE 50, 102.83 for CSI 300, 99.44 for CSI 500, and 99.76 for CSI 1000[68][72][74] - The report evaluates four futures hedging strategies based on CSI 500, CSI 300, SSE 50, and CSI 1000 indices. These strategies include "continuous monthly hedging," "continuous quarterly hedging," and "minimum discount hedging." The strategies are tested over the period from July 22, 2022, to October 17, 2025. Key metrics such as annualized return, volatility, maximum drawdown, net value, annual turnover, and year-to-date returns are analyzed for each strategy. For example, the minimum discount strategy for CSI 500 futures achieved an annualized return of -1.54%, a volatility of 4.60%, and a maximum drawdown of -7.97%[44][47][46] - The annualized basis adjustment model is introduced to account for the impact of dividend expectations on futures basis. The formula used is: $ Annualized\ Basis = (Actual\ Basis + (Expected\ Dividend\ Points))/Index\ Price \times 360/Days\ to\ Maturity $ This adjustment ensures that the basis reflects the dividend impact during the contract's lifetime[19][20][21] - The report provides dividend point forecasts for the next year for major indices: CSI 500 (81.96), CSI 300 (83.80), SSE 50 (68.34), and CSI 1000 (62.81). Additionally, the dividend points for specific contracts are estimated, such as 2.16 for IC2511, 3.95 for IF2511, 4.91 for IH2511, and 1.19 for IM2511[9][11][15][17] - The performance of the hedging strategies for each index is detailed. For example, the minimum discount strategy for CSI 300 futures achieved an annualized return of 1.23%, a volatility of 3.07%, and a maximum drawdown of -4.06%. For SSE 50 futures, the minimum discount strategy achieved an annualized return of 1.73%, a volatility of 3.05%, and a maximum drawdown of -3.91%.
