今天，A股三大指数涨跌不一。 截至收盘，上证指数下跌0.15%，深证成指、创业板指数分别上涨1.02%、2.14%。 沪深两市成交额17833亿元，较昨日小幅缩量288亿元。 在连续两天的情绪修复后，今天个股出现明显分化，下跌个股相比前两日明显增多，整个市场共有 3593只个股下跌。 大市方面，继上周五的大幅调整后，市场已反弹3天。从历次行情来看，以标志性K线宣布中期震 荡回调之后，若市场出现2-3天的反弹，此时应注意是否变盘。 尽管如此，达哥认为，当前的反弹时间略有不足，后市需注意上证指数上周五的跳空缺口能否回 补。 由于市场成交回到2万亿元之下，这意味着即便反弹，在速率上可能也不会那么快。同时，在个股 走势普遍修复之后，更应注重节奏的把握。 此时，最忌讳的是追涨杀跌，尤其是在没有持续性及没有资金大幅关照的板块。 比如，今天成交额排名前20的个股，超过一半的个股都收出了中大阳线。大成交个股吸金，在当前 市场缩量的背景下，连续上涨的可能性不会太高。 板块方面，今天AI硬件崛起，核心股全线大涨，如中际旭创(300308)、新易盛(300502)、天孚通信 (300394)、工业富联(601138)、寒武纪、海光 ...

谷歌"新王"登场，粉碎AI泡沫论？ AI四面楚歌之际，谷歌以"全栈王"的姿态出现，为算力设备投资再续命。谷歌 GEMINI3.0大模型 和 TPU芯片 两 大杀手锏的推出，意义重大。意味着谷歌不仅在推理、多模态和Agent（智能体）平台三条主线上同时实现了代 际式跃迁，而且验证了算力领域的Scaling Law（规模法则）依然有效。 也就是说：AI产业趋势仍然在螺旋式上升，算力投入"随规模提升，模型相应继续上行"的经验规律并未打破，"全 栈式"生态集成也在缩短"资金投入-智能验证-盈利回报"的时间差，而这些正是"AI泡沫论"的核心担忧。 值得一提的是，谷歌第七代TPU芯片采用的OCS技术创新，是成本压缩的关键，价格低至英伟达GPU芯片的1/5， 但在特定场景下拥有更强的推理计算能力，因而也受到Meta等大客户的青睐，又为谷歌带来新的增长极。 OCS先进在哪儿？ OCS技术全称（Optical Circuit Switching）， 也叫"光学电路交换"，不同于传统交换机，这个技术的先进之处在 于：光纤信号进入交换机后，直接光路交换，无需做光电转换。 光网络从传统"连接"功能，向智能"交换"功能演进，有效解决了 ...
