智通财经APP获悉，东吴证券发布研报称，重点关注2026年 M9产业链、光互联产业链投资机遇。PCB 材料向M9等级升级、光电共封装及"光入柜内"的确定性技术趋势。因此该行建议2026年重点关注 PCB M9 材料产业链投资机遇，以及CPO、光入柜内所对应的光芯片、光器件等领域的投资机遇。 东吴证券主要观点如下： SerDes 代际跃迁，驱动算力互联介质升级 算力芯片的互联带宽已成为衡量其性能的核心指标，而 SerDes(高速串行解串器)作为高速 IO 端口的核 心技术组件，其速率迭代直接决定了芯片互联带宽的上限。以英伟达为例，NVLink SerDes 已从 Ampere 架构的 56Gbps 演进至 Blackwell 架构的 224Gbps，支撑单芯片互联带宽实现代际跨越。然而， SerDes 速率的持续提升对 AI 服务器，交换机的信号传输介质提出严苛挑战。从速率瓶颈看，224G 以 上信号高频衰减剧增，驱动 PCB 覆铜板向 M9 级别升级;从功耗瓶颈看，SerDes 功耗占比随速率攀升， 光互联亟需通过光电近封装、共封装技术缩短与交换芯片的物理距离，以替代传统可插拔方案，实现能 效跃升。 Rubi ...

达哥昨天提到，全球AI投资者比较关注Anthropic举行的在线直播活动。 沪深京三市成交额达到24812亿元，较昨日放量2628亿元。个股涨多跌少，涨跌幅的中位数为上涨 0.62%。 指数方面，今天市场出现了一个好现象：上证指数突破了2月上旬的高点4142点。 昨天达哥提到，一旦突破4142点，则意味着大盘大概率会震荡上行。 由于上证指数上方面临4170点、4190点两个压力位，加上全国两会期间大盘多以震荡为主，因此对 于近期的行情不要预期太高，以震荡看待即可。 受此消息影响，隔夜美股AI科技股引领市场反弹，纳斯达克指数涨幅超过1%，英伟达、苹果、微 软、Meta等公司股价均有不同程度的反弹。 该消息也对A股的AI板块也有积极影响，今天AI硬件的通信设备、元器件板块明显反弹，元器件板 块指数创下历史新高，通信设备板块指数距离创历史新高仅一步之遥；AI应用的文教休闲、网络游戏 两大板块今天止跌。 我们回到市场。 今天，A股三大指数集体上涨。截至收盘，上证指数上涨0.72%，深证成指、创业板指数分别上涨 1.29%、1.41%。 从昨晚的直播活动来看，其缓解了AI颠覆的担忧。 具体来看，Anthropic的Cl ...
