1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report Since late August, the CSI 1000 Index has been in a wide - range shock after a high - level correction. Using CSI 1000 index options to build a combined strategy can better adapt to the current market environment. It is recommended to construct a long straddle strategy for the October contract to gain from the expected volatility increase and market breakthrough in October [1][13]. 3. Summary by Relevant Catalogs 3.1 Market Sentiment Analysis - The PCR of option open interest indicates that the current market sentiment is generally positive and optimistic. On September 11, after the CSI 1000 Index rose sharply, the PCR of the CSI 1000 index option open interest increased significantly, and the proportion of investors with non - bearish views is at a relatively high historical level [2][3]. 3.2 Implied Volatility Analysis - The implied volatility of options has a "pulse - like" characteristic. After the sharp rise or fall of the market, it will gradually fall back. On September 11, the sharp rise of the CSI 1000 Index pushed up the implied volatility, but it is still in the normal range. Currently, the implied volatility has stopped falling and stabilized, and there is a chance of a rebound in the future. When constructing an option portfolio strategy, a positive vega exposure should be considered [4][6]. 3.3 Index Direction Analysis - In the short term, the profit - taking of some stocks has led to a technical adjustment of the index. However, the policy is expected to be favorable, and the continuous inflow of funds will support the index in the medium and long term. Policy expectations are strong due to weak inflation data, and the coordinated efforts of supply - and demand - side policies will support corporate performance repair. There are three sources of incremental funds in the stock market, and the general trend of continuous inflow remains unchanged [7][11][12]. 3.4 Conclusion and Operational Strategy - Considering the positive market sentiment, the stabilization of implied volatility, and the expected policy and capital inflows, it is advisable to construct a long straddle strategy for the October contract of the CSI 1000 Index. This strategy can gain from the increase in volatility and the market breakthrough, with relatively controllable risks [13].

Core Viewpoint - The recent fluctuations in the CSI 1000 index are attributed to significant gains in certain stocks, leading to profit-taking and technical corrections, despite ongoing positive policy expectations and net capital inflows supporting the index [2][8]. Market Sentiment - The PCR (Put-Call Ratio) indicates a generally optimistic market sentiment, with a notable increase from 99.49% to 108.41% following a significant rise in the CSI 1000 index on September 11, suggesting a higher proportion of non-bearish investors [4][14]. - The PCR's movement aligns closely with the index's performance, reflecting the sentiment of professional investors who are less bearish [4]. Volatility Expectations - The implied volatility of the CSI 1000 index options has shown a significant increase from 21.00% to 22.81%, indicating a rise in market expectations for volatility following the index's sharp movements [7][14]. - The current implied volatility is at a relatively high historical percentile, suggesting potential for further increases in the future, particularly in light of upcoming significant economic meetings [7][14]. Policy and Economic Indicators - Recent inflation data shows a weak overall performance, with August CPI unchanged month-on-month and a year-on-year decline of 0.4%, while PPI also showed a year-on-year decrease of 2.9%, indicating a need for policy intervention to stimulate consumption [9][11]. - The government is expected to focus on policies that enhance consumer spending, with initiatives like the "old-for-new" consumption policy aimed at boosting demand and supporting corporate profitability [11][12]. Capital Inflows - There is a sustained trend of net capital inflows into the stock market, with financing balances reaching 2.3 trillion yuan, which constitutes approximately 2.58% of the market's circulating value [13][14]. - The decline in risk-free interest rates has prompted a shift in asset allocation, with investors seeking higher returns in equities, further supporting the market [13]. Strategic Recommendations - Given the current market conditions, a buy straddle strategy is recommended for October, allowing investors to benefit from potential volatility and price movements in either direction [14].
