1. Report Industry Investment Rating - No information provided in the given content 2. Core Viewpoints of the Report - Today, all stock indices fluctuated and declined. A-share trading volume throughout the day was 2.39 trillion yuan, compared with 3.16 trillion yuan the previous day. The overall stock market performance was sluggish, and trading volume significantly decreased [3]. - The continuous escalation of geopolitical conflicts has led investors to worry about the risk of macroeconomic slowdown. The willingness of funds to take profits has increased, driving the stock indices to retreat from high levels. On the one hand, the long - term nature of the conflict may affect global energy supply, leading to an increase in domestic manufacturing costs and a decrease in orders; on the other hand, high oil prices will drive up global inflation, frustrating the central bank's decision to cut interest rates and putting pressure on the valuation side of the equity market in terms of liquidity [3]. - The National Bureau of Statistics announced that the manufacturing PMI in February was 49.0%, a decrease of 0.3 percentage points from the previous month, below the boom - bust line, indicating that the problem of insufficient effective demand still exists [3]. - As the Two Sessions are approaching, the policy side has a strong determination to support macro - demand and technological innovation. The market should focus on the policy direction and intensity in the government work report of the Two Sessions [3]. - In general, the negative impact of recent Middle East geopolitical factors and the positive policy expectations of the Two Sessions are intertwined. In the short term, the stock indices will mainly fluctuate within a range [3]. - In terms of options, the implied volatility has rebounded recently. Since the logic of the medium - to - long - term upward movement of the stock indices still exists, the idea of a bull spread can be maintained [3]. 3.
