美银证券发布研报称，将香港交易所(00388)港股2025至2027年日均成交额预测由2,400亿、2,600亿及 2,600亿港元，上调至2,600亿、2,700亿及2,700亿港元，但基于低利率环境，将净投资收入预测下调5至 7%，同时将盈利预测上调1至2%，维持520港元目标价不变，重申"买入"评级。 该行预期港交所今年首三季盈利将达129亿港元，同比增长39%。今年第三季日均成交金额为2,860亿港 元，创历史新高。不过，该行预期港交所净投资收入将受期内港元拆息波动影响。虽然港元拆息已于第 二季回落，但对净投资收入的滞后影响可能到第三季才浮现，而且随着拆息于8至9月反弹，料有关影响 会于第四季消退。 美银证券又提到，预期港交所2026至2027年盈利增长，将由2025年的24%放缓至8%，除非总市值显著 提高，否则单靠成交额增长难以推动收入，并预期衍生产品将成为关键增长引擎。另外，该行料香港 IPO与沪深交易所的竞争可能加剧，因内地更重视新科技板块，或透过激励政策将重点企业留在境内上 市。 ...

Core Viewpoint - The Trump administration is expanding the scope of tariffs on various products, including white goods, which are now subject to a 50% tariff due to their classification as "derivative products" of steel and aluminum [1][2][3]. Group 1: Tariff Implementation - Starting June 23, the Trump administration imposed a 50% tariff on white goods such as washing machines, dryers, refrigerators, dishwashers, and microwaves [2]. - White goods are classified as "derivative products" of steel and aluminum, leading to tariffs based on their metal content [3]. - Approximately 20% of imported refrigerators in the U.S. come from Mexico, and 10% from South Korea, with over 20% of certain products imported from China [3]. Group 2: Impact on Imports and Prices - The cumulative tariff burden on products from China could approach 100%, which may not be fully absorbed by companies and could lead to increased retail prices [3]. - The Trump administration has previously expanded the list of products subject to steel and aluminum tariffs, including beer cans in April [3]. Group 3: Government's Stance and Future Implications - The U.S. government has not clearly defined the relationship between the newly taxed products and national security, despite the tariffs being justified on those grounds [3]. - The nature of "derivative products" has changed under the second Trump administration, indicating a stronger intent to protect domestic industries through expanded tariffs [3][4]. - The U.S. Department of Commerce has begun accepting applications for additional product categories to be included under the steel and aluminum tariffs, suggesting a proactive approach to expanding tariff applications [4]. Group 4: Concerns Over Future Tariffs - There are concerns that future tariffs could extend to other sectors, such as semiconductors, potentially including everyday consumer electronics like smartphones and personal computers [5]. - The South Korean government has expressed concerns to the U.S. Department of Commerce, advocating for the exclusion of daily consumer goods from tariff applications [5].
