1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - On September 18, 2025, the stock indexes fluctuated and declined throughout the day, with the Shanghai, Shenzhen, and Beijing stock markets having a total turnover of 3166.6 billion yuan, a significant increase of 763.7 billion yuan from the previous day. The decline was mainly due to large stock price increases and significant valuation improvements, causing investors to lose confidence in chasing prices and increasing their willingness to take profits. [3] - In the medium to long term, stock indexes are strongly supported by favorable macro - policies and net inflows of funds. Given the weak credit and inflation data in August and the slowdown in consumption growth, there is a high expectation of policies to stabilize demand, with the key window period for policy introduction expected to be in October. The significant increase in non - bank deposits in July and August and the high - level operation of margin trading balances indicate continuous inflows of incremental funds into the stock market. [3] - However, due to the significant increase in the valuation of some stocks, there is still a willingness among profitable funds to take profits, leading to short - term technical adjustment pressure on stock indexes. The subsequent focus should be on the game between the rhythm of profit - taking and the fermentation of policy expectations. In general, stock indexes are expected to experience wide - range fluctuations in the short term. [3] - Currently, the implied volatility of options has increased. Considering the long - term upward trend of stock indexes, investors can continue to hold bull spreads or ratio spreads. [3] 3. Summary According to Relevant Catalogs 3.1 Option Indicators - On September 18, 2025, most ETFs and stock indexes declined, except for the科创 50ETF and the 易方达科创 50ETF, which rose by 0.69% and 0.64% respectively. For example, the 50ETF fell 1.30% to 3.048, and the 300ETF (Shanghai Stock Exchange) fell 1.27% to 4.594. [5] - The trading volume PCR and open - interest PCR of various options changed compared to the previous trading day. For instance, the trading volume PCR of the Shanghai Stock Exchange 50ETF options was 78.41 (previous day: 87.34), and the open - interest PCR was 73.26 (previous day: 76.66). [6] - The implied volatility of at - the - money options in September or October 2025 and the 30 - trading - day historical volatility of the underlying assets were provided for different options. For example, the implied volatility of at - the - money options of the Shanghai Stock Exchange 50ETF options in September 2025 was 19.35%, and the 30 - trading - day historical volatility of the underlying asset was 15.12%. [7] 3.2 Relevant Charts - Multiple charts were presented for different types of options, including the trend of the underlying asset, volatility, trading volume PCR, open - interest PCR, implied volatility curve, and the implied volatility of at - the - money options for different terms. For example, for the Shanghai Stock Exchange 50ETF options, there were charts showing its trend, volatility, trading volume PCR, etc. [9][11][13]

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints - Today, all stock indices fluctuated and rebounded. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 2402.9 billion yuan, showing an increase of 35.9 billion yuan compared to the previous day [3]. - The Ministry of Commerce and eight other departments recently issued the "Several Policy Measures for Expanding Service Consumption," proposing 19 specific measures in five aspects to boost consumption demand. Promoting the development of service consumption can create new service - related jobs and stimulate household consumption, thus promoting a positive economic cycle on both the supply and demand sides [3]. - In August, credit and inflation data were weak, and the consumption growth rate slowed down, indicating weak demand from the real - sector. There is a strong expectation for the introduction of policies to stabilize demand in the future, with the key window period for policy introduction expected to be in October [3]. - In July and August, non - bank deposits increased significantly, and the margin trading balance remained at a high level, indicating that the stock market has continuously attracted incremental capital inflows. However, due to the significant increase in the valuations of some stocks previously, there is still a willingness among profit - taking funds to lock in profits, which also leads to short - term technical adjustment pressure on the stock indices. In the future, attention should be paid to the game between the profit - taking rhythm of funds and the fermentation of policy expectations [3]. - In general, the stock indices are expected to experience wide - range fluctuations in the short term [3]. - Currently, the implied volatility of options is within the normal range. Considering the long - and medium - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads [3]. 3. Summary by Related Catalogs 3.1 Option Indicators - On September 17, 2025, the 50ETF rose 0.19% to close at 3.088; the 300ETF (Shanghai Stock Exchange) rose 0.71% to close at 4.653; the 300ETF (Shenzhen Stock Exchange) rose 0.73% to close at 4.800; the CSI 300 Index rose 0.61% to close at 4551.02; the CSI 1000 Index rose 0.95% to close at 7554.81; the 500ETF (Shanghai Stock Exchange) rose 1.03% to close at 7.357; the 500ETF (Shenzhen Stock Exchange) rose 1.27% to close at 2.944; the ChiNext ETF rose 1.96% to close at 3.119; the Shenzhen 100ETF rose 1.36% to close at 3.497; the SSE 50 Index rose 0.17% to close at 2952.78; the STAR 50ETF rose 0.98% to close at 1.44; and the E Fund STAR 50ETF rose 0.86% to close at 1.41 [5]. - For option volume PCR and position PCR, specific values for different options on September 17, 2025, and the previous trading day are provided, such as the 50ETF option volume PCR being 87.34 (previous day: 98.00) and position PCR being 79.25 (previous day: 78.16) [6]. - For the implied volatility of at - the - money options and the 30 - day historical volatility of the underlying assets, specific values for different options are provided, such as the 50ETF option's 2025 September at - the - money option implied volatility being 18.05% and the 30 - day historical volatility of the underlying asset being 15.12% [7]. 3.2 Related Charts - The report provides various charts for different options, including the price trends, volatility, volume PCR, position PCR, implied volatility curves, and at - the - money implied volatility of different terms for options such as the 50ETF option, 300ETF option (Shanghai and Shenzhen Stock Exchanges), CSI 1000 index option, 500ETF option (Shanghai and Shenzhen Stock Exchanges), ChiNext ETF option, Shenzhen 100ETF option, SSE 50 index option, STAR 50ETF option, and E Fund STAR 50ETF option [9][21][34]

There is a strong expectation for the introduction of policies to stabilize demand in the future, and the critical window period for policy introduction is expected to be in October [4]. - In terms of capital, incremental funds have been continuously flowing into the stock market. The non - bank deposits increased significantly in July and August, and the margin trading balance remained at a high level, indicating that the stock market has continuously attracted incremental funds. However, due to the significant increase in the valuations of some stocks in the early stage, there is still a willingness among profit - taking funds to take profits, which also leads to short - term technical adjustment pressure on the stock indices. In the future, focus on the game between the profit - taking rhythm of funds and the fermentation of policy expectations [4]. - In general, the stock indices are expected to experience wide - range fluctuations in the short term. Currently, the implied volatility of options is in the normal range. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads [4]. 3. Summary by Related Catalogs 3.1 Option Indicators - On September 16, 2025, the 50ETF fell 0.48% to close at 3.082; the 300ETF (Shanghai Stock Exchange) fell 0.19% to close at 4.620; the 300ETF (Shenzhen Stock Exchange) fell 0.23% to close at 4.765; the CSI 300 Index fell 0.21% to close at 4523.34; the CSI 1000 Index rose 0.92% to close at 7483.63; the 500ETF (Shanghai Stock Exchange) rose 0.77% to close at 7.282; the 500ETF (Shenzhen Stock Exchange) rose 0.73% to close at 2.907; the GEM ETF rose 0.72% to close at 3.059; the Shenzhen 100ETF remained unchanged at 3.450; the SSE 50 Index fell 0.50% to close at 2947.82; the STAR 50ETF rose 1.21% to close at 1.43; the E Fund STAR 50ETF rose 1.23% to close at 1.39 [7]. - The trading volume PCR and position PCR of various options on September 16, 2025, and their changes compared to the previous trading day are provided, including those of 50ETF options, 300ETF options (Shanghai and Shenzhen Stock Exchanges), CSI 300 Index options, CSI 1000 Index options, 500ETF options (Shanghai and Shenzhen Stock Exchanges), GEM ETF options, Shenzhen 100ETF options, SSE 50 Index options, STAR 50ETF options, and E Fund STAR 50ETF options [8]. - The implied volatility of at - the - money options and the 30 - trading - day historical volatility of the underlying assets of various options in September or October 2025 are provided, including those of 50ETF options, 300ETF options (Shanghai and Shenzhen Stock Exchanges), CSI 300 Index options, CSI 1000 Index options, 500ETF options (Shanghai and Shenzhen Stock Exchanges), GEM ETF options, Shenzhen 100ETF options, SSE 50 Index options, STAR 50ETF options, and E Fund STAR 50ETF options [9][10]. 3.2 Related Charts - For each type of option (such as 50ETF options, 300ETF options, etc.), relevant charts are provided, including the underlying asset's trend chart, option volatility chart, trading volume PCR chart, position PCR chart, implied volatility curve chart, and at - the - money implied volatility chart for different terms [11][22][35][38][51][66][79][93][106][119][134][141].

1. Report Industry Investment Rating - No relevant content provided. 2. Core View of the Report - Today, all stock indices rebounded unilaterally. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 2.4646 trillion yuan, an increase of 460.6 billion yuan compared to the previous day. Since early September, due to the significant increase in the prices of some individual stocks and a notable rise in the valuation, some investors' willingness to chase the market has weakened, and the profit - taking of profitable funds has led to a technical adjustment of the stock indices. However, the positive policy expectations and the continuous inflow of funds into the stock market still provide long - term support for the stock indices. The Minister of Finance pointed out that "in the next step, more efforts will be made to strengthen the domestic cycle, and more proactive and effective macro - policies will be implemented in a timely manner." Combined with the weak inflation data in August, it means that policies to boost the demand side will continue to be introduced, and the expectation of policy benefits is rising. On the other hand, incremental funds continue to flow into the stock market. The balance of margin trading has exceeded 2.3 trillion yuan and remains at a high level. The significant increase in non - bank deposits in July indicates that the trend of residents' maturing time deposits shifting to equity market allocation is gradually taking shape. The increasing expectation of the Fed's interest rate cut is conducive to driving the flow of the US dollar to emerging economies. Therefore, the trend of net inflow of incremental funds into the A - share market remains unchanged, which is expected to promote the repair of the stock market valuation. However, attention should still be paid to the intensity of profit - taking at the current position, and the subsequent market trend depends on the game between profit - taking and the fermentation of policy expectations. In general, the stock indices are expected to fluctuate widely in the short term [3]. - Currently, the implied volatility of options is within the normal range. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads [4]. 3. Summary According to Relevant Catalogs 3.1 Option Indicators - On September 11, 2025, the 50ETF rose 1.63% to close at 3.122; the 300ETF (Shanghai Stock Exchange) rose 2.69% to close at 4.660; the 300ETF (Shenzhen Stock Exchange) rose 2.56% to close at 4.800; the CSI 300 Index rose 2.31% to close at 4548.03; the CSI 1000 Index rose 2.35% to close at 7399.89; the 500ETF (Shanghai Stock Exchange) rose 3.16% to close at 7.224; the 500ETF (Shenzhen Stock Exchange) rose 3.14% to close at 2.891; the ChiNext ETF rose 5.22% to close at 3.025; the Shenzhen 100ETF rose 3.82% to close at 3.451; the SSE 50 Index rose 1.48% to close at 2983.08; the Science and Technology Innovation 50ETF rose 5.45% to close at 1.39; the E Fund Science and Technology Innovation 50ETF rose 5.50% to close at 1.36 [6]. - The trading volume PCR and position PCR of various options changed compared with the previous trading day. For example, the trading volume PCR of the SSE 50ETF option was 74.33, and the previous trading day was 98.65; the position PCR was 90.71, and the previous trading day was 83.10 [7]. - The implied volatility of at - the - money options in September 2025 and the 30 - day historical volatility of the underlying for various options are provided. For example, the implied volatility of at - the - money options of the SSE 50ETF option in September 2025 was 15.17%, and the 30 - day historical volatility of the underlying was 15.60% [8]. 3.2 Relevant Charts - The report includes a series of charts for different options, such as the SSE 50ETF option, SSE 300ETF option, etc. These charts show the trends, volatilities, trading volume PCR, position PCR, implied volatility curves, and various - term at - the - money implied volatilities of the underlying assets of the options [10][20][33].

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - On September 4, 2025, all stock indices showed weak oscillations and significant declines. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2581.9 billion yuan, an increase of 186.2 billion yuan from the previous day, and nearly 3000 stocks declined. Due to the significant gains of some stocks, the profit - taking demand of profit - making funds increased, leading to a short - term technical adjustment in the stock indices, with the CSI 500 and CSI 1000 indices being more affected. However, in the medium - to - long term, the positive policy expectations and loose capital situation strongly support the stock indices, and the logic of their upward movement remains strong. Recently, the joint working group of the Ministry of Finance and the People's Bank of China held its second group leader meeting, indicating a clear expectation of policy support for the economy. The liquidity is relatively loose, and in the context of the "asset shortage", the attractiveness of equity assets is strong, with incremental funds continuously flowing in, which will drive the repair of stock valuations. In general, due to the increased profit - taking demand of profit - making funds, the stock indices are expected to fluctuate widely in the short term. Currently, the implied volatility of options continues to rise. Considering the medium - to - long - term upward trend of the stock indices, one can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3. Summary by Related Catalogs 3.1 Option Indicators - On September 4, 2025, the 50ETF fell 1.72% to 3.034; the 300ETF (Shanghai Stock Exchange) fell 2.04% to 4.456; the 300ETF (Shenzhen Stock Exchange) fell 2.11% to 4.593; the CSI 300 Index fell 2.12% to 4365.21; the CSI 1000 Index fell 2.30% to 7041.15; the 500ETF (Shanghai Stock Exchange) fell 2.32% to 6.779; the 500ETF (Shenzhen Stock Exchange) fell 2.62% to 2.710; the GEM ETF fell 4.15% to 2.751; the Shenzhen 100ETF fell 2.54% to 3.226; the SSE 50 Index fell 1.71% to 2910.47; the STAR 50ETF fell 6.08% to 1.28; and the E Fund STAR 50ETF fell 6.22% to 1.25 [5]. - The trading volume PCR and position PCR of various ETF options and index options changed compared to the previous trading day. For example, the trading volume PCR of SSE 50ETF options was 94.23 (75.73 the previous day), and the position PCR was 81.16 (87.40 the previous day) [6]. - The implied volatility of at - the - money options in September 2025 and the 30 - trading - day historical volatility of the underlying assets of various options were reported. For instance, the implied volatility of at - the - money options of SSE 50ETF options in September 2025 was 19.16%, and the 30 - trading - day historical volatility of the underlying asset was 14.44% [7]. 3.2 Related Charts - The report provides a series of charts for different types of options, including the trends, volatility, trading volume PCR, position PCR, implied volatility curves, and at - the - money implied volatility of different terms of various ETF options and index options such as SSE 50ETF options, SSE 300ETF options, etc. [9][19][32]

1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View - On September 3, 2025, all stock indices fluctuated and declined. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.3957 trillion yuan, a decrease of 516.7 billion yuan from the previous day. Due to the significant increase in some stocks, the profit - taking demand of profitable funds has risen, and the recent trading volume of the stock market has shrunk, indicating a certain divergence in market expectations, and the stock indices have entered a short - term technical adjustment. In the long - term, the expectation of policy benefits and the loose capital situation strongly support the stock indices, and the logic of the long - term upward movement of the stock indices remains strong. Anti - involution policies and consumption - promotion policies optimize the supply - demand structure from both the supply and demand sides, promote a moderate increase in the price index, and repair corporate profits. In terms of capital, the margin trading balance has risen rapidly, non - bank deposits have soared, and long - term funds have continued to enter the market. The continuous inflow of incremental funds in the stock market promotes the repair of stock valuations. In general, in the short term, the marginal effect of policy benefit expectations has weakened, and the profit - taking demand of profitable funds has increased. The stock indices are expected to fluctuate widely in the short term. Currently, the implied volatility of options continues to rise. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Today, all stock indices fluctuated and consolidated. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 2777.6 billion yuan, a decrease of 52.5 billion yuan compared to the previous day. Currently, the trading volume of the stock market remains at a high level, indicating that the overall market sentiment is still relatively optimistic. In the short term, due to the significant increase in some stocks, there is a risk of technical adjustment caused by profit - taking of profitable funds, and there is a need for funds to rotate between high - and low - valued stocks. The main driving forces for this round of stock index rebound are the positive policy expectations and the loose liquidity in the capital market. Anti - involution policies and consumption - promotion policies promote the optimization of the supply - demand structure from both the supply and demand sides, leading to a moderate recovery of the price index and the repair of corporate profits. In terms of the capital market, the margin trading balance has risen rapidly, non - bank deposits have increased sharply, and long - term funds have continued to enter the market. The continuous inflow of incremental funds into the stock market has boosted the logic of stock valuation repair. Overall, the current market sentiment is generally positive, and the upward trend remains unchanged. However, there are some differences in the short - term market, and the stock index is expected to maintain a loose and volatile trend in the short term. - Currently, the implied volatility of options continues to rise. Considering the long - and medium - term upward trend of the stock index, investors can continue to hold bull spreads or ratio spreads for a moderate bullish view [3]. 3.
