1. Report Industry Investment Rating - Not provided in the content. 2. Core Viewpoints of the Report - For stock index futures, Trump's sudden tariff threat will disrupt the stock index in the short - term. Last week, each stock index rose first and then fell, with a slight decline. In the long - term, policy expectations and capital inflows support the stock index. The subsequent trend of the stock index depends on the game between policy expectation fermentation and profit - taking. Trump's tariff threat on Friday night led to a sharp drop in US stock indexes, bringing short - term pressure on the stock market, but the impact on A - shares is weaker than in early April [1][7][79]. - For ETF options and stock index options, maintain a bull spread in a low - volatility state. The implied volatility of options has declined to a low level. Since the probability of the stock index rising in the long - term is high, one can hold a bull spread or a ratio spread with a mild bullish view [2][80]. 3. Summary by Directory 3.1 Market Review 3.1.1 Stock Index Trends - Last week, each stock index rose first and then fell, with a slight decline. Due to the significant increase in stock valuations, the profit - taking intention of profitable funds increased. With policy benefits about to be implemented, the policy - driven effect will weaken. In the long - term, policy expectations and capital inflows support the stock index [7]. - The table shows the price changes of spot indexes. For example, the Shanghai Composite 50 Index closed at 2974.854, with a daily decline of 1.51% and a weekly decline of 0.47% [8]. 3.1.2 Option Price Trends - This week, the 50ETF had a weekly decline of 1.90%, closing at 3.045; the 300ETF (Shanghai Stock Exchange) had a weekly decline of 0.37%, closing at 4.604; etc. The report also provides the price changes and weekly fluctuations of various option underlying assets and the weekly price changes of the main contracts of each option variety [13][14][15]. 3.1.3 Stock Index Futures Basis and Monthly Spread - The basis of the four stock index futures varieties shows that IF and IH are at normal quantile levels, while IM and IC are in a state of significant far - month futures discounts. The inter - period spreads of IC and IM futures have increased, indicating a strong short - term risk preference for IC and IM in the market [19]. 3.2 Option Indicators 3.2.1 PCR Indicators - The report provides the trading volume PCR and open interest PCR of various options, such as the Shanghai Composite 50ETF option, with a trading volume PCR of 113.82 and an open interest PCR of 71.82 [31]. 3.2.2 Implied Volatility - The report provides the implied volatility of at - the - money options in October 2025 and the 30 - trading - day historical volatility of the underlying assets for various options. For example, the implied volatility of the Shanghai Composite 50ETF option's at - the - money option in October 2025 is 16.72%, and the 30 - trading - day historical volatility of the underlying asset is 15.73% [52]. 3.3 Conclusion - Similar to the core viewpoints, for stock index futures, Trump's tariff threat disrupts the stock index in the short - term, and the stock index will fluctuate widely in the short - term. For ETF options and stock index options, maintain a bull spread in a low - volatility state [79][80].

Core Viewpoint - The A-share market is expected to maintain a bullish trend in Q4 2025, but faces increased macroeconomic uncertainties, particularly regarding US-China trade policies, leading to heightened market volatility. Investors are encouraged to utilize options to create a balanced portfolio to navigate this turbulence and enhance returns [1]. Group 1: Market Trends - In Q3 2025, the market favored trading growth-oriented index options, with the CSI 1000 index options holding a market share of 33.29%, a slight decrease of 2.9 percentage points from the previous quarter. The Southern CSI 500 ETF options followed with an 18.05% share, down 4 percentage points, while the ChiNext ETF options rose to 12.85%, an increase of 4.2 percentage points [2]. - The PCR (Put-Call Ratio) values for major financial options showed an upward trend, with the CSI 300 index options rising from 65% to around 100%, and the CSI 1000 index options increasing from 95% to approximately 120%, before retreating to a range of 90%-100% [2]. Group 2: Volatility Analysis - Implied volatility for options exhibited a clear pattern of rising and then declining in Q3 2025. The average implied volatility for CSI 300 and CSI 1000 options peaked at 24.11% and around 29% respectively in late August, before decreasing to approximately 15% and 22% [3]. - The implied volatility reached historical highs, with CSI 300 and CSI 1000 options touching the 90% and 87% percentiles over the past three years, indicating a more rational investor sentiment compared to previous market surges [3]. Group 3: Future Outlook - Looking ahead to Q4, the market remains in a bullish phase, with the CSI 300 index's bond-equity ratio at a two-standard-deviation extreme below the past three-year average. Implied volatility is at historical lows, but there is potential for an upward spike due to US-China trade uncertainties [5]. - Investors are advised to consider selling out-of-the-money put options after market sentiment stabilizes, as this strategy offers a higher margin of safety compared to direct long positions in index futures. Additionally, a shift from unilateral upward movement to a range-bound market is anticipated, suggesting that investors holding long positions in index futures should consider selling out-of-the-money call options to generate additional income [5].
