南方财经 21世纪经济报道记者吴斌报道 随着华尔街对AI热潮是否可能演变为泡沫的担忧加剧，英伟达的惊艳业绩未能打消投资者的担忧。 在美国东部时间2月25日的盘后交易中，英伟达股价最初上涨4%，随后回吐涨幅，并最终在26日收跌 5.45%。 在大跌之前，英伟达给出的第一财季业绩展望轻松超出分析师平均预期，且第四财季营收大幅增长 73%。 英伟达炸裂财报未能重振AI交易，26日纳指大跌逾1%。标普500指数收跌0.54%，报6908.86点；纳指跌 1.18%，报22878.38点；道琼斯工业平均指数涨0.03%，报49499.2点。 英伟达缘何陷入财报下跌"魔咒" 但分析师仍越来越担心英伟达依赖少数几家被称为"超大规模云服务商"的大型数据中心运营商，以及 OpenAI等AI初创企业。Visible Alpha研究主管Melissa Otto表示，英伟达面临"很多担忧"，涉及其所依赖 的大型科技公司和初创企业客户如何为数千亿美元的AI基础设施支出提供资金。 微软、谷歌、亚马逊和Meta今年合计预计资本支出为6600亿美元，主要集中在AI数据中心。这些科技 巨头现在面临着在烧钱如山的情况下进入债券和股票市场融资的前 ...

美国知名投资者、电影《大空头》原型人物迈克尔·伯里表示，英伟达为了满足其微芯片的预期需求， 已将自身置于一个"危险的境地"，倘若人工智能热潮消退，该公司可能会遭受"灾难性的"财务打击。 伯里周四在 Substack 上发表了一篇题为"英伟达加大风险"的帖子，称他在该公司的年度报告中发现了一 个"令人担忧"的项目：其采购义务在 12 个月内从约 160 亿美元激增至 950 亿美元。 伯里表示，这是由于主要供应商台积电坚持要求签订更长期的合同，并以现金支付，以此作为建设满足 英伟达最新芯片生产所需产能的条件。 "需要明确的是，英伟达被迫在需求尚未明确的情况下就下达了不可取消的采购订单，"伯里写道，并补 充说，该公司将库存转化为销售所需的时间也更长了。 "这一新的现实情况表明，这是有意做出的举措，即比以往任何时候都更进一步地锁定供应链产能。" 伯里指出，英伟达总计 1170 亿美元的供应义务几乎与截至 1 月 25 日的年度运营现金流持平。 他写道："这并非寻常之事。这是风险。" 伯里将这种情况与互联网泡沫时期的思科进行了比较。当时，这家互联网网络巨头延长了与供应商的采 购承诺，以确保其有能力支持预期的每年 50 ...
