资金面则显示了明显的"避险"和"求稳"倾向。央行今日加量投放流动性，缓解了资金面担忧，但新入市 的资金以及部分存量资金，在近期全球科技股波动加剧的背景下，选择了流向股息率高、业绩稳定、且 受益于政策托底的板块。煤炭正是这类资产的典型代表。这种从成长向价值的仓位腾挪，是造成板块 间"跷跷板"效应的直接推手。 外部市场的传导效应也不容忽视。港股恒生科技指数今日再度大跌2.29%，其中软件与半导体板块跌幅 尤甚。这既受到全球范围内对AI技术颠覆传统商业模式担忧情绪的影响，也反映出国际资金对部分高 估值科技领域的重新定价。A股与港股在科技股上的联动性日益增强，这种负面情绪很自然地传导至A 股的TMT板块。 重点谈谈领涨的煤炭板块。它的崛起并非简单的超跌反弹。在"能源安全"的战略框架下，煤炭行业的定 位正在发生微妙变化，从单纯的"传统能源"向"稳定器"和"现代化产业基础"转变。这带来了估值体系重 塑的潜在可能。叠加其自身低估值、高现金流的财务特征，在不确定性上升的市场中，它自然成为了防 御性配置的优选。今日的暴涨，是市场对这份"确定性"给予的溢价。 展望未来，这种分化的态势可能不会迅速结束。市场将从普涨普跌的"贝塔行情 ...
