今日A股冲高回落，指_老虎社区_美港股上老虎

今日A股冲高回落，指数小幅收跌，成交维持高位，市场分化明显，热点轮动飞快。汽车、农业、医药相对抗跌，周期资源板块出现回调，不少个股冲高回落。晚间无重大突发消息，外围不确定性仍在。操作上切忌追涨短线热点，高位标的逢高兑现，不急于大举抄底，严控仓位，耐心等待市场企稳信号，重点观察主线能否延续。

光通信集体反弹,没有消息也能涨一天?

光通信周三集体反弹。Lumentum收涨9.59%报919.40美元,领涨标普500,Marvell收涨3.61%报229.71美元,同一天AXT涨11.44%,Semtech涨11.03%,Coherent涨约6%。翻了一圈,没有一条属于Lumentum自己的消息:没有财报,没有指引,没有订单,也没有评级调整。市场把这轮涨归到两件事上,一是这批票前面跌得太深,周三是超跌之后的回补;二是共封装光学的热度,AXT当天就是被点名成这个方向的赢家。对照着看更清楚,周一重挫14%的康宁这天没跟上。多头的抓手是AI要搬的数据早晚得落到光这一层,产能是真紧的;空头的抓手是没有公司层面的消息撑着,涨得快的退得也快。这轮光通信的涨,有多少是真需求?
