不过，重返白宫的美国总统唐纳德·特朗普向包括欧盟在内的大部分国家征收所谓"对等关税"，令经济 增长前景陷入高度不确定。欧盟在 90天贸易谈判窗口内大多数出口商品将面临美国政府设立的10%对 等关税，钢铁和铝制品，以及汽车整体和汽车零部件则面临25%关税举措，并且欧盟与美国贸易谈判走 向仍然未知。 欧盟本月稍早同意将对美国政府主导的25%钢铝关税的反制措施延后90天实施。此举是在特朗普将对大 多数欧盟出口产品的所谓"对等关税"税率暂时从 20% 降至 10%、关说豁免的时间期限同为90天之后所 作出的决定。特朗普还对欧盟以及全球范围的汽车以及部分零部件加征了大约25% 的关税。 特朗普政府已经开始对中国(美国前三大贸易伙伴之一)征收高达145%的惊人关税，并对大多数其他国家 征收至少10%关税，尽管对于消费电子、半导体等某些细分领域暂时豁免关税，但是许多经济预测人士 因此警告未来全球经济将急剧放缓，部分人甚至预测今年美国就将出现深度经济衰退。 智通财经APP获悉，德国3月份的工厂整体订单增幅超过市场普遍预期，显示在美国关税政策宣布之 前，欧洲最大规模经济体的制造业形势有所改善。然而，特朗普政府掀起的新一轮面向全 ...

Group 1 - The report highlights a significant shift in the US-China trade dynamics since the implementation of Trump's tariffs, with the share of US imports from China dropping from 21.6% in 2017 to 13.4% in 2024, indicating a rapid "de-China-ization" trend [11][13][31] - Conversely, China's exports to the US have increased by 22% from 2017 to 2024, with the export value rising from 429.8 billion USD to 524.7 billion USD, showcasing a contrasting trend in trade statistics [11][12][31] - The report notes that the indirect value added from China in US imports has grown significantly, from 75.3 billion USD in 2017 to 148.9 billion USD in 2024, a 97.7% increase, indicating resilience in the value chain despite direct trade reductions [26][27][31] Group 2 - The analysis indicates that the US's attempts to decouple from China have not significantly reduced the overall trade linkages, with the indirect trade connections through value chains largely compensating for the decline in direct trade [4][31][32] - The report discusses the impact of Trump's tariffs on global supply chains, particularly highlighting that labor-intensive products, which are most affected by tariffs, are the least likely to return to the US [5][37][41] - It emphasizes that the diversification of supply chains is becoming essential for US importers to mitigate tariff risks, particularly in labor-intensive industries, which are expected to accelerate their dispersal [5][48][50]

Core Viewpoint - The traditional stock market saying "May is poor, June is desperate, and July is a turnaround" does not hold true based on statistical analysis of the A-share market from 1991 to 2024, indicating that the calendar effect is a misconception [1] Group 1: Market Analysis - The A-share market has shown that from 2009 to 2024, April generally has a low probability of rising, while August tends to have a larger average decline [1] - June and July have relatively high probabilities of rising, contrary to the saying, with May showing a rise probability of less than 50% but not being the lowest month [1] - In the earlier period from 1991 to 2008, October had the lowest probability of rising, while May and June had higher probabilities, further debunking the "poor May" notion [1] Group 2: Sector Focus - In May, the market is expected to shift back to technology growth sectors, with catalysts including updates on AI large models and developments in robotics [2] - Key areas of focus include AI applications in cloud computing, office automation, and healthcare, as well as the ongoing trend of domestic semiconductor production [2] - The low-altitude economy is anticipated to gain momentum following the announcement of pilot cities, with strong expectations for construction and development in related sectors [2] Group 3: Market Performance - Recent market performance showed a broad increase in individual stocks, with nearly 5,000 stocks rising and trading volume expanding to 1.3 trillion, indicating a recovery in market sentiment [3] - Technology sectors such as computers, communications, machinery, media, and electronics led the gains, while defensive sectors like food and beverage showed minimal increases [3]

Core Viewpoint - The article discusses the impact of the recent "reciprocal tariffs" announced by Trump on the global market, particularly focusing on the Chinese market and its recovery trends following the initial shock [1][3]. Market Performance Summary - Following the announcement of tariffs on April 2, the Hong Kong stock market experienced significant volatility, with a notable drop on April 7 that erased all gains for the year. However, by May 2, the Hang Seng Tech Index rebounded by 19.1%, while MSCI China, Hang Seng Index, and Hang Seng China Enterprises Index saw rebounds of 13.6%, 13.5%, and 13.3% respectively. The Shanghai Composite Index and CSI 300 had smaller rebounds of 5.9% and 5.0% [1]. - Sector performance from April 8 to May 2 showed that Information Technology (+29.0%), Healthcare (+19.2%), and Consumer Discretionary (+14.3%) led the gains, while sectors like Banking (+4.9%), Utilities (+5.6%), and Energy (+5.9%) lagged behind [1]. Industry Analysis Framework - The article proposes an industry analysis framework based on demand sources, categorizing industries into three main types: 1. Industries primarily dependent on the U.S. market, which face significant challenges in finding alternative demand. 2. Industries with demand from markets outside the U.S., which are less directly affected by U.S. tariffs. 3. Industries with domestic demand, which are influenced by domestic policy support [4][6]. Impact of Tariffs on Different Industries - Industries with primary demand from the U.S. are categorized based on their ability to find alternative markets and their bargaining power. Sectors like Media, Software Services, and Textiles have shown resilience due to higher profit margins and U.S. import dependency, while smaller firms in shipping and medical supplies face greater challenges [6][10]. - Industries with demand from other markets, particularly those with established market shares and competitive advantages, are expected to perform better. Sectors such as Technology Hardware and Home Appliances have shown potential for growth in non-U.S. markets [11][14]. - Domestic demand-driven industries, particularly in consumption and infrastructure, are closely tied to government policy support. The article highlights the importance of fiscal measures to mitigate external shocks [18][20]. Historical Context and Future Outlook - The article draws parallels with the 2018-2019 trade tensions, noting that the current market dynamics reflect similar patterns of initial decline followed by recovery phases. The sectors that are less dependent on U.S. demand have shown more resilience, while those heavily reliant on U.S. markets have faced significant declines [21][25]. - The potential impact of tariffs on GDP and corporate profits is discussed, with estimates suggesting that a significant drop in exports to the U.S. could lead to a decline in GDP growth and a downward adjustment in profit forecasts for Hong Kong stocks [34][35]. - The article concludes with a projection of market indices under different scenarios, emphasizing the need for policy support to counterbalance the negative effects of tariffs and the importance of sector-specific strategies for investors [37].
