The half - day trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1.8499 trillion yuan, an increase of 113.6 billion yuan compared to the previous day [3]. - In July, the month - on - month decline of PPI narrowed, and the supply - demand relationship in some industries improved, with prices showing positive changes.

Currently, the stock market's risk appetite is rising, and it is expected that stock indices will fluctuate strongly in the short term [3]. - The current implied volatility of options is within the normal range.

1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - Today, all stock indices fluctuated and consolidated. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1619.9 billion yuan, a decrease of 342 billion yuan from the previous day. Due to the significant gains of some stocks since late June, some profit - taking funds have a need to lock in profits, so the stock indices have a short - term need for technical consolidation. The recent decline in the trading volume of the stock market indicates a decline in investors' risk appetite. Since incremental policy benefits may need to wait until the Fourth Plenary Session of the 20th CPC Central Committee in October, the driving force of policy benefits has weakened marginally in the short term. In general, the stock indices are expected to fluctuate within a range in the short term. Currently, the implied volatility of options has rebounded.

1. Report Industry Investment Rating - No relevant content found 2. Core Viewpoints of the Report - On July 22, 2025, all stock indices fluctuated slightly upward. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets reached 1928.6 billion yuan, an increase of 201.5 billion yuan from the previous day. The current trading volume in the stock market is at a relatively high level, indicating that investors' risk appetite is relatively positive. The recent rebound of the stock indices is mainly driven by policy - positive expectations. Anti - involution policies are helpful to boost the profit margins of related industries such as photovoltaic, new energy vehicles, and resource - based cyclical stocks. The official start of the Yaxia Super Hydropower Project has boosted the risk appetite of investors in infrastructure stocks. However, since late June, some stocks have achieved significant increases, and there may be a rotation in the capital market in the future, which may slow down the upward momentum of the stock indices. It is necessary to pay attention to the policy statements of the Politburo meeting. In general, the stock indices will fluctuate strongly in the short term. Currently, the implied volatility of options has rebounded. Considering that the stock indices are more likely to rise in the medium and long term, investors can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3.
