Report Industry Investment Rating - No relevant content provided Core Viewpoints - Today, all stock indices oscillated and rebounded. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.0904 trillion yuan, a decrease of 506.2 billion yuan from the previous day. The volume - shrinking rebound of the stock market reflects that the overall market sentiment remains optimistic, with funds entering the market on dips after corrections, and the downside space for stock indices is limited. At the same time, it also shows that funds chasing higher near the previous high points remain relatively cautious [4]. - In the short term, the tariff war has resurfaced, and external uncertainties have increased before November. Coupled with the current relatively high valuation level, investors' willingness to take profits has risen, and there is short - term technical correction pressure. In the medium to long term, the problem of insufficient effective domestic demand still exists, and the disturbance of external tariff factors still remains. There are strong expectations for policy - makers to stabilize the macro - fundamentals, and the expectation of policy benefits forms strong support for the stock indices. The trend of net capital inflow into the A - share market remains unchanged, so the stock indices have strong medium - to - long - term support. Overall, under the game between profit - taking sentiment and policy support, the stock indices are expected to maintain wide - range oscillations in the short term [4]. - Currently, the implied volatility of options remains relatively stable. Considering the medium - to - long - term upward trend of the stock indices, investors can continue to hold bull spreads or covered calls [4].

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].
