The Shanghai Stock Exchange 50 Index rose slightly after a rise and fall throughout the day, while the CSI 500 and CSI 1000 showed weak performance and closed slightly lower. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2,306.3 billion yuan, an increase of 131.1 billion yuan from the previous day.

Industry Investment Rating - No investment rating information provided in the report Core Viewpoints - Today, all stock indices fluctuated within a narrow range. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1736.3 billion yuan, a decrease of 116.2 billion yuan from the previous day. The economic indicators in the first half of the year showed strong resilience, and the expectation of short - term policy intensification has weakened, but the expectation of policy support still exists. Policy support and the expectation of anti - involution policy benefits have promoted the recovery of the stock market's risk appetite, combined with the suspension of overseas uncertainty risks, jointly driving the recovery of the stock market's risk appetite. Considering that some stocks have achieved significant gains, there is a need for technical consolidation in the market outlook. With the approaching deadline of the Sino - US tariff suspension period, there is a possibility of consolidation and accumulation of momentum for stock indices in the short term. However, in the long term, the upward trend of stock indices remains unchanged. Currently, the risk appetite of the stock market is relatively positive, and it is expected that stock indices will maintain a volatile and slightly stronger trend in the short term. Since the implied volatility of options is currently in the normal range and stock indices are expected to rise in the medium and long term, investors can continue to hold bull spreads or ratio spreads for a moderate bullish view [3] Summary by Directory 1 Option Indicators - **ETF and Index Performance**: On August 8, 2025, 50ETF fell 0.38% to 2.910; 300ETF (Shanghai Stock Exchange) fell 0.24% to 4.183; 300ETF (Shenzhen Stock Exchange) fell 0.25% to 4.315; CSI 300 Index fell 0.24% to 4104.97; CSI 1000 Index fell 0.35% to 6838.13; 500ETF (Shanghai Stock Exchange) fell 0.17% to 6.397; 500ETF (Shenzhen Stock Exchange) fell 0.16% to 2.556; ChiNext ETF fell 0.34% to 2.312; Shenzhen 100ETF fell 0.24% to 2.893; SSE 50 Index fell 0.33% to 2789.17; STAR 50ETF fell 1.44% to 1.10; E Fund STAR 50ETF fell 1.38% to 1.07 [5] - **Volume PCR and Open Interest PCR**: The volume PCR and open interest PCR data of various options on August 8, 2025, and their changes compared with the previous trading day are provided, including 50ETF options, SSE 300ETF options, SZSE 300ETF options, CSI 300 index options, CSI 1000 index options, SSE 500ETF options, SZSE 500ETF options, ChiNext ETF options, Shenzhen 100ETF options, SSE 50 index options, STAR 50ETF options, and E Fund STAR 50ETF options [6] - **Implied Volatility and Historical Volatility**: The implied volatility of at - the - money options in August 2025 and the 30 - day historical volatility of the underlying assets of various options are presented, such as 50ETF options, SSE 300ETF options, SZSE 300ETF options, CSI 300 index options, CSI 1000 index options, SSE 500ETF options, SZSE 500ETF options, ChiNext ETF options, Shenzhen 100ETF options, SSE 50 index options, STAR 50ETF options, and E Fund STAR 50ETF options [7][8] 2 Related Charts - **50ETF Options**: Include charts of 50ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [9][10][11] - **SSE 300ETF Options**: Include charts of SSE 300ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [20][21] - **SZSE 300ETF Options**: Include charts of SZSE 300ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [23][24] - **CSI 300 Index Options**: Include charts of CSI 300 index trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [36][37] - **CSI 1000 Index Options**: Include charts of CSI 1000 index trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [49][50] - **SSE 500ETF Options**: Include charts of SSE 500ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [62][63] - **SZSE 500ETF Options**: Include charts of SZSE 500ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [75][76] - **ChiNext ETF Options**: Include charts of ChiNext ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [90][91] - **Shenzhen 100ETF Options**: Include charts of Shenzhen 100ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [101][102] - **SSE 50 Index Options**: Include charts of SSE 50 index trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [114][115] - **STAR 50ETF Options**: Include charts of STAR 50ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [128][129] - **E Fund STAR 50ETF Options**: Include charts of E Fund STAR 50ETF trends, option volatility, volume PCR, open interest PCR, implied volatility curve, and at - the - money implied volatility of different terms [131][132]
