据新华社消息，位于纽约的美国国际贸易法院28日裁定暂停特朗普政府4月2日宣布的一揽子加征关税政 策生效。 上述一揽子加征关税政策，指的是特朗普4月2日签署行政令，宣布对所有贸易伙伴征收所谓"对等关 税"。 美国的"对等关税"政策，当时引发全球资本市场大幅震荡，A股市场也受外盘影响一度出现大幅调整， 不过此后市场开始修复。 美国国际贸易法院的消息，成为今天市场反弹的重要因素，因为其刺激了短线市场风险偏好情绪的回 暖。不过，美国的相关关税政策依然面临着不确定性。 昨天，达哥在文章中援引了中信证券的观点。中信证券表示，从2025年四季度开始，港股和A股市场有 望迎来指数牛市。 不过，在昨天文章的评论区，不少粉丝朋友不太认同上述观点，认为量化资金会成为牛市的绊脚石。 自去年10月8日大盘见到波段高点以来，已经震荡了快8个月。在震荡的过程中，不少人追涨杀跌，没怎 么赚钱。 不过，有一个事实不可否认，那就是期间的板块行情足以让人获得或多或少的收益，比如飞行汽车、商 业航天、低空经济、人形机器人、DeepSeek概念等板块。 最近8个月没有怎么赚钱，一个重要原因就是没有踩准板块行情。 个股涨多跌少，整个市场有4472只个股 ...

作者 | 张旦珺 编辑 | 江江 值班编辑｜ 宝珠 视觉 | 顾芗 艾伦在去年离开了金融行业，原因是"收入太低"。 虽然艾伦一入行就遇到了大熊市，但按照当时普遍的职业发展路径，券商分析师在工作两三年后年薪能 达到40万，而五年后，成熟的分析师可冲刺百万年薪。 如今，五年节点已经到了，艾伦的月收入变成了四位数。扣掉社保和公积金，一个月到手只有6000多 元。上海的生活成本不低，艾伦感到难以为继。 分析师的薪资与创收高度挂钩，艾伦告诉盐财经："2021年下半年，排名前50的券商佣金加起来，半年 可以创收100个亿，（但）现在基本上是以前的1/3。" 投行部门情况同样不容乐观。在深圳某券商投行部门工作的林华对 盐财经表示："基本上年终奖都没有 了。" 金融行业的降薪现象大约已持续三年之久。以高薪闻名的两大券商中，中信证券的人均年薪从2021年的 94.7万下降至2024年的77.98万，中金公司从116.72万下降到64.26万，接近腰斩。 | | 2024年人均薪酬 | | | | --- | --- | --- | --- | | 证券名称 | 2024年(万元) 2023年(万元) | | 同比变化 | | ...
