本周A股市场呈现回暖态势，科创50指数以6.5%的涨幅领跑各大指数。政策面上，LPR利率维持不变，预制菜国标正在推进；中美关系保持稳定；钢铁行业 迎来稳增长方案。分析师普遍认为节后市场大概率延续上行趋势，TMT板块尤其值得关注。 作为一名量化投资者，我发现每当市场回暖时，散户投资者总会陷入一种"踩高捧低"的怪圈：觉得涨得多的股票风险大，转而追逐那些看似"便宜"的低位 股。这种思维方式看似理性，实则暗藏认知陷阱。 所谓"高低"，不过是事后回看的结果。就像2020年时茅台股价突破2000元时多少人惊呼"太高了"，而今寒武纪等科技股创下新高时同样质疑声不断。但事实 是：股价能走多远不取决于它已经涨了多少，而在于机构资金参与的意愿。 我观察到一个有趣的现象：当散户在讨论"高低"时，专业机构却在研究交易行为数据。这就像两个人在森林里遇到熊，一个人忙着计算逃跑速度是否够快， 另一个人则在观察熊的行为模式——前者关注结果，后者关注本质。 以银行股为例。2022年以来银行板块持续走强，期间质疑声从未间断："估值太高""业绩无法支撑"…但如果我们不是凭感觉判断高低，而是观察机构资金的 行为呢？ 图中清晰显示机构资金早已撤离白酒 ...
