眼下炒A股,要有对待美股七姐妹的觉悟
Sou Hu Cai Jing· 2025-08-12 15:03
最近美股"七巨头"又成了市场焦点。美国银行最新调查显示,45%的基金经理认为资金过度集中在这七只股票上。Meta、微软等公司财报亮眼,特斯拉却表 现不佳。表面上看,这似乎又是一个关于市场热点的普通新闻。但毕竟是入行几十年,我看到的却是另一番景象。 二、量化视角下的市场真相 我用了十多年的量化工具告诉我:真正重要的是当下正在发生什么。股价涨跌只是表象,背后的资金行为才是本质。就像"七巨头"的分化表现,表面看是业 绩差异,深层看是机构资金的不同态度。 通过长期积累的交易行为数据,我们可以清晰地看到机构资金的真实动向。比如下面这只近期表现抢眼的股票: 图中橙色柱体反映的是机构资金的活跃程度。这只股票在45个交易日内出现7次涨停,期间有四次明显的调整(图中①、②、③、④位置)。如果只看股价 波动,很多人可能会选择出局。但数据告诉我们:机构资金一直在积极参与。 一、市场表象下的深层逻辑 "七巨头"的强势表现确实引人注目。Meta、微软等公司的强劲财报,尤其是AI相关业务的出色表现,让市场重新燃起热情。美联储降息预期更是火上浇油, CME数据显示9月降息概率高达90.7%。但有趣的是,特斯拉却成为"七巨头"中唯一的例外。 ...

新基金发行创新高,8月难道要开始抢盘?
Sou Hu Cai Jing· 2025-08-11 05:08
最近A股回暖,公募基金发行市场也跟着热闹起来。7月份新发基金147只,创下年内新高,权益类产品占比提升到45%。表面看是市场信心恢复,但作为一 个在资本市场摸爬滚打多年的老手,我更关心的是:这些数字背后,机构们到底在打什么算盘? 一、历史总是惊人地相似 很多人对"历史会重复"这句话嗤之以鼻,但如果你不是特别纠结于细节的话,投资市场确实存在惊人的相似性。每一轮牛市几乎都伴随着市场情绪极度亢 奋、开户数暴增、社交媒体上财富神话满天飞,最终以崩盘收场。 具体到中国股市,你会发现牛市往往与五年规划周期相关。2009年、2014年、2019年的牛市都处于规划交替期,政策推动与市场情绪形成共振。历史并非没 有重复,只是不以你预想的方式出现罢了。 所以历史当然会重复,关键看你关注的是什么… 比如,新进增猛增时,追高的人往往短期就会别套。原因就是,这种时候机构对于成本特别敏感。 二、好股票的共同基因 价值投资典范巴菲特也很注重控制成本。他在2023年股东信中透露:7年13亿美元买了4亿股可口可乐,折合每股成本3.25美元。而从1988年到1994年的7年 间,可口可乐股价最低35美元。 这就是为什么不要空谈价值投资——即便是 ...
