Report Industry Investment Rating - No relevant content provided. Core Viewpoints of the Report - The underlying index market remains in a bull market in Q4 2025, but there is a local overheating of leveraged funds in the short - term. The implied volatility of options is at a moderately low level, and there may be local volatility pulses in Q4 due to increased Sino - US relations uncertainty. In a bull market with a negative skew structure, shorting out - of - the - money put options after local volatility pulses is worth attention. As Sino - US relations uncertainty grows, index trends may shift from unilateral upward to range - bound, and investors with long futures positions are advised to sell out - of - the - money call options near the upper bound of the range for additional income [4][5][66]. Summary by Relevant Catalogs 2025 Pre - Q3 Financial Options Market Operation Option Market Activity Highly Differentiated - There are 12 listed financial options, with 5 on the SSE, 4 on the SZSE, and 3 on the CFFEX. From January 1 to September 25, 2025, the total trading volume was 1.353 billion contracts, with an average daily trading volume of 7.516 million contracts, a total turnover of 1.25744 trillion yuan, an average daily turnover of 6.986 billion yuan, and an average daily open interest of 8.706 million contracts. Compared with the same period in 2024, the average daily trading volume, turnover, and open interest increased by about 17%, 48%, and 47% respectively. In Q3 2025, the average daily turnover increased by 101.4% quarter - on - quarter. The turnover of small - and medium - cap index options and ChiNext options increased significantly, while that of large - cap index options changed little [10][11][12]. Market Prefers to Trade Growth - Oriented Index Options - In Q3 2025, the CSI 1000 index options had the highest market share at 33.29%, followed by the Southern CSI 500 ETF options at 18.05%, and the ChiNext ETF options at 12.85%. The market generally prefers growth - oriented index options with higher volatility [14]. The PCR of Open Interest Indicates Over - Enthusiasm among Put Option Sellers - In Q3 2025, the PCR of open interest of major financial options mostly followed the underlying index's fluctuations, showing an upward - trending oscillation. The PCR of IO and MO options reached extremely high levels above the 99th percentile, indicating an over - proportion of put option sellers and local market overheating [20]. Stock Index Options Market Volatility Option Implied Volatility Shows an Up - and - Down Trend - In Q3 2025, the implied volatility of options first rose and then fell. The average implied volatility of IO and MO options reached around the 90th and 87th percentiles in the past three years, respectively. During the upward movement of the underlying index, the implied volatility showed different patterns at different stages. Currently, the implied volatility has returned to a relatively low level in the past five - year period, and the room for further decline is limited [23][28][29]. The Proportion of Negative Skew Decreased Significantly in Q3 - The proportion of negative skew in Q3 decreased compared with Q2. The decrease was partly due to the end of the dividend period of index component stocks and the stagnation of small - cap stocks after late August, which reduced the hedging demand of public and private funds. The buying momentum of out - of - the - money call options weakened after reaching a high in late August, indicating market caution [33][35]. The Frequency of "Near - Low, Far - High" Implied Volatility Increases - Taking the CSI 300 and CSI 1000 index options as examples, the proportion of the "near - low, far - high" term structure of the CSI 1000 index options increased in Q3, indicating a relatively stable market trend and a lower frequency of short - term sharp fluctuations, suggesting a healthier and more sustainable market upward movement [38][40]. Q4 Volatility Outlook - In Q3 2025, the difference between the implied volatility and the 30 - day historical volatility of IO and MO options had a certain range of fluctuations, and the average difference showed that the environment for option sellers improved compared with Q2. Currently, the implied volatility of the CSI 300 and CSI 1000 index options has bottomed out and rebounded, with a moderately low premium level. There is a possibility of upward volatility pulses in Q4 [41][42][44]. Option Strategy Review and Recommendation Long - Term Excess Returns of IM Long Positions - As of October 10, 2025, long - term holding of the IM current - month contract has achieved a cumulative return of 44.5%, 11.2 percentage points higher than the CSI 1000 index. However, there was a significant retracement from mid - August to early September due to the stagnation of small - cap stocks and the convergence of futures discounts [45]. Returns of Put Option Sellers in the First Three Quarters - Back - testing shows that although put option sellers did not outperform the underlying index in Q3, the stability of the fund curve was better, and the average retracement was significantly reduced [48]. Quantitative Timing Strategy Based on Option Synthetic Underlying Premiums - The quantitative timing strategy based on ETF option synthetic underlying premiums has achieved an annualized return of 19.5% and a maximum retracement of 17.83% on the CSI 500 index futures since 2018. In the first three quarters of 2025, it achieved an absolute return of 21.41% with a maximum retracement of only 3.25% [54]. Classic Option Double - Selling Strategy - The double - selling strategy is most suitable for the relatively stable SSE 50 index options, with a cumulative return of 12.96% and a maximum retracement of less than 6% in the first three quarters of 2025. The IO option double - selling strategy has achieved positive returns but suffered a significant retracement during the unilateral market since July. The MO option double - selling strategy has the most unstable returns, with a cumulative return of - 2.52% and a relatively large maximum retracement [56][58]. Q4 2025 Outlook - In Q4 2025, the underlying index market is still in a bull market, but there is local overheating of leveraged funds in the short - term. The implied volatility of options is at a moderately low level, and there may be local volatility pulses. In a bull market with a negative skew structure, shorting out - of - the - money put options after local volatility pulses is worth attention. As Sino - US relations uncertainty grows, index trends may shift from unilateral upward to range - bound, and investors with long futures positions are advised to sell out - of - the - money call options near the upper bound of the range for additional income [66].
