香橼在报告中强调，闪迪目前的估值被严重高估，市场对其成长性的判断存在根本性偏差。该机构将闪 迪类比为"英伟达式"的高成长股，认为其产品本质属于高度同质化的大宗商品，而非具有长期技术壁垒 的企业。报告的核心逻辑在于存储行业的强周期性特征，NAND闪存作为闪迪的主要产品，其价格和盈 利能力受供需周期影响较大。 花旗集团近期上调了2026年的预期，将DRAM和NAND平均售价涨幅分别调高至88%和74%，称市场进 入"失控式上涨"和"剧烈卖方市场"。AI基础设施投资带来的需求增长远超供给，短缺状况可能贯穿全 年。 历史上，存储行业多次经历"繁荣—过剩—崩盘"的完整周期。例如，2012年智能手机需求推动价格上涨 后，主要厂商扩产导致NAND价格下跌约50%；2018年数据中心扩张带动高峰，但随后供过于求， NAND价格暴跌70%。这些案例表明，当前约50%的高毛利通常是周期顶部的标志，而非可持续状态。 此外，香橼还注意到闪迪前母公司兼重要股东西部数据近期以低于市价的价格大规模减持股份，用于偿 债等用途。该机构认为这是内部人士对周期见顶的预判，与散户追捧形成鲜明对比。 对于中国内地投资者而言，中韩半导体ETF成为布局韩 ...

在存储芯片行业超级周期引发的大牛市下，知名做空机构香橼研究(Citron Research)突然做空美股存储 龙头闪迪(SanDisk,SNDK.US)，香橼称目前存储供应紧张仅为暂时现象，一旦主要厂商良率修复并释放 产能，供需格局可能在一次财报电话会议中彻底逆转。 香橼研究于2月24日通过社交媒体平台发布详细做空报告，该报告宣布建立闪迪的空头头寸，并系统阐 述其看空逻辑，认为闪迪当前估值严重高估，市场对其成长性的认知存在根本性误判。报告将闪迪类比 为"英伟达式"成长股的错误定位，强调其产品本质上属于高度同质化的大宗商品，而非具备长期护城河 的技术垄断型企业。 值得注意的是，1月29日，闪迪公司CEODavidGoeckeler在2026年第二季度财报电话会议中强调，AI对 高带宽内存(HBM)和NAND的需求代表"结构性而非周期性转变"，已根本改变存储市场的商业模式。该 公司高管还强调，此结构性演进将降低NAND业务的周期波动性，并带来更高的长期平均毛利率。 在闪迪股价回升之际，韩国"存储双雄"三星和海力士股价也双双创下历史新高。2月26日，三星电子 (005930.KRX)收盘价218,000韩元，日内涨 ...

智通财经2月25日讯（编辑 胡家荣）美东时间周二，近期备受市场追捧的存储芯片龙头闪迪股价遭遇剧烈波动。知名做空机构香橼资本公开宣布持有闪迪空 头头寸，并发布详细看空报告。受此消息冲击，闪迪股价盘中一度跌近8%。 这一利空消息迅速产生连锁反应，波及港股存储概念股。截至发稿，澜起科技(06809.HK)跌6.38%，兆易创新(03986.HK)跌4.77%，显示市场对存储行业周期 性风险的担忧情绪正在蔓延。 针对市场普遍预期的"AI需求将帮助NAND闪存摆脱周期性波动"的观点，香橼资本予以驳斥。报告回顾历史指出，2008年、2012年及2018年均出现过类似行 情，但周期性规律从未改变。 香橼强调，当前的供应短缺仅是暂时现象。目前全球产能已达到2018年峰值的两倍，所谓的供应限制可能在一次财报电话会议后便烟消云散。报告直 言："英伟达拥有护城河，而闪迪销售的只是普通商品。"市场将闪迪对标英伟达进行高估值定价，存在根本性逻辑错误。 三星竞争加剧：价格战与技术挤压双重威胁 香橼资本特别强调了来自三星电子的巨大威胁。历史上，三星在存储周期中常采取"优先市场份额而非利润"的策略：先让纯闪存厂商享受高毛利，随后突然 增加供 ...

Core Viewpoint - The article emphasizes the importance of recognizing trends in the business world, highlighting that the infrastructure supporting these trends often contains the most certain investment opportunities. The significant rise in the stock price of SanDisk, which increased by 559% in 2025, exemplifies this point, as it outperformed well-known tech companies like Nvidia and Tesla [1][2]. Group 1: Market Dynamics - SanDisk's stock surge reflects a broader trend where storage companies dominated the top gainers in the market, with Western Digital, Micron, and Seagate also ranking high [2]. - The demand for storage in AI applications has skyrocketed, with a single AI server requiring 5 to 10 times more storage than traditional servers [4][5]. - The shift in AI usage from training to inference means that real-time data access is crucial, leading to increased demand for high-speed storage solutions [8].
