科技股成了今天的重灾区。 通信设备、半导体板块跌幅超过2%，前几天还风光无限的AI硬件概念集体熄火。 这直接拖累了创业板，指数一浪低过一浪。 反倒是消费类股票像酿酒、商业连锁一度逆势抬头，中央商场、茂业商业等个股涨停，但独木难支，完全带不动市场情绪。 收盘数据显示，高达4058只个股收绿，跌停股12只。 今天A股这走势，看得人心里发凉。 开盘就低开，虽然金融股试图护盘让指数短暂回暖，但午后科技股直接砸盘，三大指数集体收跌。 最吓人的是量能——全天成交额只有1.77万亿元，比上个 交易日整整缩水了3188亿！ 这可不是小数目，相当于市场里的活钱突然少了一大截。 盘面上，保险、证券这些金融权重早盘直线拉升，却只是昙花一现。 它们就像个"救场不出力"的保安，阻止场面崩溃，但压根没想推动局势好转。 而没有 持续性的护盘，反而消耗了多头的力量。 外资的态度也很暧昧。 北向资金虽然偶尔净流入，但规模有限，完全是一副试探姿态。 主力资金净流出超过600亿元，几乎每小时都在卖出。 这种缩量下跌的格局，表明市场已经进入"躺平模式"——场内的人不愿卖，场外的人不敢进。 有经验的老股民都清楚，缩量下跌比放量下跌更可怕。 放量至少说 ...
