Stock A closing review | Trump's "ultimatum" expires tonight A shares close in low volume! Institutions: Focus on two big events in April.

As the deadline set by Trump for Iran ceasefire negotiations approaches on Tuesday evening Eastern Time, global market sentiment tightens again: international oil prices fluctuate higher, US stock futures fall, and Bitcoin erases its gains from the previous day. The limited ceasefire signal and ongoing escalation risks are wrestling with each other, causing investors to generally choose to wait and see. However, the three major indexes of A-shares rose collectively in the afternoon, with more stocks rising than falling in both markets, with nearly 4000 stocks rising. At the close, the Shanghai Composite Index rose by 0.26%, the Shenzhen Component Index rose by 0.36%, the ChiNext Index rose by 0.36%, and the Sci-Tech Innovation 50 Index rose by over 1%. The total turnover of the Shanghai and Shenzhen stock markets was 1.61 trillion, a decrease of 42.1 billion from the previous trading day. Hithink Research recently stated that April will see two major events reshaping the market logic: First, starting from April 10th, there will be intensive disclosure of financial reports, with annual and first-quarter reports to be completed by April 30th. Institutional funds will adjust their positions according to the economic outlook, and the direction of performance increase is worth noting. Second, a heavyweight meeting will be held in late April, and policy signals are crucial. Regardless, it is not advisable to panic sell or heavily bottom-fish; one should control their positions and wait for volume signals.

Institutional Views China Securities Co., Ltd.: Market awaits bottom fishing opportunities In a research report, China Securities Co., Ltd. pointed out that the Iran situation continues to escalate and is complex and constantly changing. The market is fluctuating around negotiation signals, while at the same time, US military actions are transitioning from airstrikes to ground operations preparations. The next 2-3 weeks are still a high-risk period when the situation could deteriorate sharply, and the market is waiting for bottom fishing opportunities, with funds adopting a short-term wait-and-see attitude. On the other hand, internal fundamental factors are worth reconsidering, with a series of data jointly supporting the trend of improving economy. As March economic data is about to be published and the financial reporting season approaches, the market's focus will gradually shift to the substantive verification of economic recovery and corporate profit improvement. Patiently lay out along three clues: energy security and inflation theme, certainty of growth assets, and benefiting from policies and seasonal prosperity. Key industries to focus on: oil and gas production, coal, coal chemical industry, power equipment, utilities, chemical industry, AI industry chain, innovative drugs, infrastructure industry chain, service consumption, and so on. EB SECURITIES: The A-share market has likely found the bottom in the short term, and may focus on oscillatory repair in the future The A-share market has likely found the bottom in the short term, and may focus on oscillatory repair in the future. In terms of allocation, it is advisable to layout around the two main themes of "benefiting from high oil prices + performance certainty": First, the energy theme, including industries directly benefiting from the rise in oil prices such as coal, coal chemical, oil and gas, shipping ports, as well as new energy sectors like photovoltaics, energy storage, wind power, nuclear power with energy substitution logic; Second, the high-performance technology theme, focusing on areas with industry trends and strong performance realization capabilities like electronics (semiconductors, AI hardware), communication, power equipment (AI power, energy storage). CMSC: Market focus in mid to late April will shift to high-growth areas in Q1 performance Looking ahead to April, A-shares still face unresolved external risks. The US is currently accelerating its military buildup, and with the completion of the deployment of the "Bush" aircraft carrier battle group in mid-April, the likelihood of ground operations significantly increases. There is a risk of a higher-than-expected escalation of the US-Iran conflict. Against this backdrop, the market's concerns about global economic stagnation will further intensify the pressure for oil prices to rise. If the US launches a ground attack in mid to late April, whether due to casualties exceeding expectations, or a surge in oil prices triggering a deep correction in global stock markets, the Trump administration may be forced to shift to a conciliatory strategy, and the market may witness a typical dilemma reversal rally.
