1. Report Industry Investment Rating - No relevant content found 2. Core Viewpoints of the Report - Today, the trends of various stock indices have diverged. Among them, the CSI 500 and CSI 1000 have oscillated and slightly increased, while the SSE 50 and SSE 300 have oscillated and sorted within a narrow range. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets is 2.1608 trillion yuan, with an increase of 159.7 billion yuan compared to the previous day.

Since the long - term upward logic of the stock indices is relatively solid, the bull spread strategy is maintained [3]. 3.

The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2001.0 billion - 2037.0 billion yuan. Due to the approaching holiday, investors' trading willingness was relatively weak.

The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.1247 trillion yuan, a decrease of 145.4 billion yuan compared to the previous day. As silver stopped falling and rebounded, market sentiment improved, and the stock index's operation logic returned to its fundamental factors. However, due to the approaching holiday, the demand for cash during the holiday and concerns about uncertainties, the willingness of funds to trade was relatively weak, and the trading volume of the stock market remained around 2 trillion yuan. In the medium to long term, the positive policy expectations and the continuous net inflow of incremental funds into the stock market remain unchanged, and the core logic for the medium to long - term upward movement of the stock index is relatively solid.

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - On February 6, 2026, the stock indices oscillated with slight declines, and the trading volume of the Shanghai, Shenzhen, and Beijing stock exchanges was 2.1635 trillion yuan, a decrease of 30.8 billion yuan from the previous day [3]. - The sharp fluctuations in silver disturbed market sentiment, increasing the willingness of funds to take profits and exit, leading to a continuous contraction in stock market trading volume [3]. - In the short - term, macroeconomic indicators have weakened, and the "weak reality" pressure has increased.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - On February 3, 2026, all stock indices fluctuated and rose. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.5656 trillion yuan, a decrease of 41 billion yuan from the previous day. As gold and commodity prices stabilized, the resource cycle sector rebounded, and the risk appetite of the stock market recovered. This rebound was a technical correction of the previous over - decline caused by the weakening of risk appetite in the stock market due to the sharp correction in the commodity market. Currently, the trading volume in the stock market remains in a shrinking state, indicating that the upward driving force of the stock market is still weak. Due to the weakening of macro - economic indicators and the fact that the increase in this stock rebound is mainly contributed by the valuation side, the willingness of investors in the capital market to take profits has increased, and it is difficult for the capital side to form a consistent force in the short term. However, in the long - term, the positive policy expectations and the continuous net inflow of incremental funds into the stock market remain unchanged, and the logic of the long - term upward movement of stock indices is relatively solid. In general, the risk appetite of the stock market is cautiously optimistic in the short term, and stock indices will mainly fluctuate and consolidate. For options, considering the relatively solid long - term upward logic of stock indices, a bull spread strategy can be adopted [3]. 3. Summary According to Relevant Catalogs 3.1 Option Indicators - **ETF and Index Performance**: On February 3, 2026, the 50ETF rose 0.91% to close at 3.108; the 300ETF (Shanghai Stock Exchange) rose 1.39% to close at 4.664; the 300ETF (Shenzhen Stock Exchange) rose 1.25% to close at 4.864; the CSI 300 Index rose 1.18% to close at 4660.11; the CSI 1000 Index rose 2.93% to close at 8209.10; the 500ETF (Shanghai Stock Exchange) rose 3.94% to close at 8.366; the 500ETF (Shenzhen Stock Exchange) rose 3.07% to close at 3.324; the GEM ETF rose 1.88% to close at 3.313; the Shenzhen 100ETF rose 1.41% to close at 3.463; the SSE 50 Index rose 1.05% to close at 3034.58; the STAR 50ETF rose 1.31% to close at 1.55; the E Fund STAR 50ETF rose 1.22% to close at 1.50 [5]. - **Volume PCR and Open Interest PCR**: The report provides the volume PCR and open interest PCR of various options on February 3, 2026, and their values on the previous trading day. For example, the volume PCR of SSE 50ETF options was 98.31 (previous day: 104.47), and the open interest PCR was 68.38 (previous day: 67.34) [6]. - **Implied Volatility and Historical Volatility**: The report presents the implied volatility of at - the - money options in February 2026 and the 30 - trading - day historical volatility of the underlying assets for various options. For instance, the implied volatility of at - the - money SSE 50ETF options in February 2026 was 20.31%, and the 30 - trading - day historical volatility of the underlying asset was 13.81% [7]. 3.2 Related Charts The report includes a series of charts for different types of options, such as the SSE 50ETF options, SSE 300ETF options, etc. These charts show the trends, volatility, volume PCR, open interest PCR, implied volatility curves, and at - the - money implied volatility of different terms of the underlying assets of each option [9][18][21].

1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - On January 29, 2026, stock indices showed volatile differentiation. The SSE 50 Index led the gains, while the CSI 500 and CSI 1000 Indices rose first and then fell. The total trading volume of the Shanghai, Shenzhen, and Beijing stock exchanges was 325.94 billion yuan, an increase of 26.71 billion yuan from the previous day. In the short term, the driving force for the upward movement of stock indices has weakened, and there is a high demand for the CSI 500 and CSI 1000 Indices, which have had large previous gains, to consolidate through fluctuations. The defensive nature of the SSE 50 Index has attracted capital attention. In the medium to long term, positive policy expectations and the continuous net inflow of incremental funds into the stock market are the main supporting forces for the upward movement of stock indices. Overall, stock indices are likely to fluctuate and consolidate in the short term. For options, considering the relatively solid medium - to long - term upward logic of stock indices, a bull spread strategy can be adopted [4]. 3.

1. Report Industry Investment Rating - No relevant content provided. 2. Core Viewpoints of the Report - The stock indexes fluctuated and consolidated today. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2992.3 billion yuan, a 70.8 - billion - yuan increase from the previous day. Currently, the stock market is in a consolidation phase, with a divergence in the capital market between chasing up and taking profits, leading to increased intraday volatility. In the short term, the upward drive of the stock index is weakening due to the regulatory authorities' clear intention to control risks and the fact that the recent stock price rebound is mainly driven by valuation. In the long term, positive policy expectations and the continuous inflow of incremental funds into the stock market are the main supporting forces for the upward movement of the stock index, and the risk appetite of the stock market remains positive. Overall, the stock index will mainly fluctuate and consolidate in the short term. For options, a bull - spread strategy can be considered due to the relatively reliable long - term upward trend of the stock index [4]. 3.
