The trading volume of the Shanghai, Shenzhen, and Beijing stock markets is 1518.2 billion yuan, a decrease of 101.7 billion yuan from the previous day. The trading volume remains above 1.5 trillion yuan, indicating a high - level risk appetite among stock market investors [3]. - The economy showed strong resilience in the second quarter, reducing the short - term expectation of policy intensification. The subsequent incremental positive factors need to wait until October, so the positive policy drive has weakened recently [3]. - Since late June, some stocks have achieved significant gains, and some profit - taking funds have a need to lock in profits. Therefore, the stock indices have a short - term need for technical consolidation.

In the short term, the stock indices are more likely to rise than fall.

Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - The inter - bank market's funding situation remained loose on Thursday, with overnight rates oscillating at a low level around 1.36%. The 7 - day weighted average rate dropped 3.79bp to 1.4674%. The central bank's liquidity injection is expected to stay loose due to external uncertainties from trade frictions, but the scope for further loosening of the funding situation is limited as long - term bond yields are relatively low and the inter - bank bond market leverage ratio has risen above 108% [4]. - The stock index continued to fluctuate and rise. The US - Vietnam trade agreement may have a negative impact on China's re - export trade, while the lifting of export restrictions on China by three US chip design software suppliers will boost the relevant A - share electronics sector. In the short term, the stock index may present a volatile pattern due to shrinking trading volume and lackluster domestic and foreign positive factors. In the long term, the Politburo meeting in late July will set the policy tone for the second half of the year. Given the possible deterioration of real estate sales and investment and the overall weakness of consumption, policies are expected to further support domestic demand. Additionally, the uncertain US tariff policy, the approaching Fed rate - cut time, and changes in overseas liquidity and geopolitical patterns will bring phased trading opportunities for the stock index [6]. 3.

Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - In the short - term, the stock index may present a volatile pattern due to gradually shrinking trading volume and lack of significant domestic and foreign positive factors.

Group 1: Report Industry Investment Rating - The industry investment rating for the stock index is "Oscillation" [1] Group 2: Core Viewpoints of the Report - In May, fundamental factors changed little. Against the backdrop of a protracted trade - war, the story of China's asset revaluation driven by fundamental inflection points is difficult to start. It is expected that the stock index will continue to oscillate in June, and a band - operation strategy is recommended [3] - The current stock index rally is mainly driven by retail sentiment and theme speculation, with domestic liquidity as the main source, making the A - share index relatively independent globally.
