韩国股市正经历一场历史性狂飙。综合三重驱动力——AI浪潮引爆的存储芯片超级周期、持续压缩的"韩国折价"以及宏观政策的积极配合——韩国综合 股价指数（Kospi）今年以来已累计上涨近50%，成为全球表现最亮眼的主要股市。 Kospi周四首次收于6300点上方，在过去11个交易日中有10天录得上涨，连续刷新历史高位。德意志银行策略师Jim Reid将其称为"2026年最非凡的股票 市场"，并指出这一涨幅"通常需要数年乃至数十年，而非数周"。高盛此前将Kospi年末目标价上调至5700点，但该指数已在一周内超越这一目标。 这场涨势的直接催化剂是内存芯片价格的垂直拉升——超大规模云计算厂商正在抢购一切可得的DRAM和HBM芯片。三星电子和SK海力士合计占Kospi 总市值约40%，两者年内分别上涨82.5%和69.8%。 与此同时，据华尔街见闻此前文章指出，韩国总统李在明凭早年炒股亏损的"散户"经验，自去年6月上任后通过强化董事会问责、改革股息税及打击市 场违规，掀起激进的金融改革。这些举措进一步放大了这轮行情。 AI存储超级周期：行情的核心引擎 此轮Kospi暴涨的最直接驱动力，来自全球AI基础设施建设对内存芯片的 ...

据《华尔街日报》报道，每天下午大约4:30，在美国爱达荷州博伊西（Boise）建设中的美光科技工厂 的地面都会因一系列受控爆炸而震动，工程师们正轰炸玄武岩基岩，将计划建设的这座巨大的新半导体 工厂下方的地面夷平。 美光是美国最大的存储芯片制造商，这些芯片是从智能手机、汽车电脑到笔记本电脑和数据中心等各种 设备所必须的数据存储芯片。美光正急于增加制造产能，以应对存储行业40多年来的最为严重的供应紧 张情况。 美光公司总部位于博伊西，计划投资500亿美元，将其450英亩的园区面积扩大一倍以上，包括建设两座 新的晶圆厂。第一晶圆厂主要生产DRAM芯片，主要用于制造高带宽存储芯片（HBM），这些芯片对 先进人工智能计算日益重要，首批晶圆预计将在2027年中期下线。第二座晶圆厂预计于2028年底投产。 每个晶圆厂面积为60万平方英尺——相当于10个以上的足球场大小——使其成为美国有史以来最大 的"无尘室"之一。 为了准备该场地，工程师们已经使用了超过700万磅炸药。一支由建筑工人、建筑承包商和建筑师组成 的团队，搭建了一个"小城市"的拖车，以便他们能全天候工作。 每个博伊西晶圆厂预计将使用7万吨钢材（几乎与建造金门大桥 ...

上周DRAM现货价格走弱，这也是2025年9月以来首次回调。 遭受存储涨价潮重压的下游厂商们，或许能稍稍"喘口气"了。 据美银最新报告显示，在连涨多个月之后，上周DRAM现货价格走弱，这也是该价格自2025年9月以来 首次出现回调。 随着DRAM现货价持续攀升，已有多家OEM反映，低阶PC、智能手机与平板中的DRAM成本占比已高 于合理水准。一般而言，DRAM成本占比在终端产品售价中的比例低于一成，但按照目前现货价格计 算，部分产品已难以吸收相关成本。 不过，现货价与合约价情况不同，一线OEM与普通OEM的成本也不尽相同。 TrendForce今日发布的存储产业调查显示，2026年第一季AI与数据中心需求持续加剧全球存储器供需失 衡，原厂议价能力有增无减，全面上修第一季DRAM、NAND Flash各产品价格环比增幅，预估整体 Conventional DRAM合约价将从一月初公布的55%~60%环比增幅，改为上涨90%~95%，NAND Flash合 约价则从环比增幅33%~38%上调至55%~60%，并且不排除仍有进一步上调空间。 此外，美银已上调存储产业中期展望，将2026 年DRAM与NAND平均销售 ...
