Group 1: Report Industry Investment Rating - None provided in the content Group 2: Core Viewpoints of the Report - Today, all stock indexes rose rapidly in the early morning, but their subsequent trends diverged. CSI 1000 and CSI 500 remained stable at high levels, while SSE 50 and SSE 300 fell from their highs and gave back some gains. The total turnover of the stock market was 121.34 billion yuan, an increase of 17.95 billion yuan from the previous day, indicating a recovery in market sentiment [3]. - The US International Trade Court blocked the tariff policy announced by US President Trump on April 2, and ruled that Trump overstepped his authority. The legal challenges faced by the US government's tariff policy eased tariff concerns and boosted the risk appetite of the stock market. However, the tariff issue still faces significant uncertainties in the later stage, and the final ruling may require the intervention of the US Supreme Court. Therefore, the impact of this news on market sentiment is short - term [3]. - Currently, the upside and downside spaces of stock indexes are relatively limited. The policy support and the need to stabilize stock market expectations have a strong supporting effect, while external uncertainties and weak domestic demand suppress the upward momentum of stock indexes from the aspects of risk appetite and profit expectations respectively. It is expected that stock indexes will maintain a range - bound oscillation in the short term [3]. - The implied volatility of options is currently within the normal range, and the implied volatility of options has rebounded recently. Considering the long - term upward trend of stock indexes, bull spreads or ratio spreads long portfolios can be arranged [3]. Group 3: Summary by Related Catalogs 1.
