当地时间周二，人工智能软件企业Palantir的首席执行官Alex Karp公开抨击卖空势力，并特别点出电影 《大空头》原型人物迈克尔·伯里（Michael Burry）的名字。 此前曝光的文件表明，伯里旗下基金已对Palantir与英伟达这两大AI行业龙头实施了做空布局。 上周五，伯里已在社交平台X上释放了明确信号，他分享了《大空头》中饰演自己的演员克里斯蒂安·贝 尔神情错愕注视电脑屏幕的剧照，并配文称："有时，我们能察觉泡沫的存在。有时，我们能采取行动 应对。有时，唯一的获胜方式就是选择不参与。" 而本周一披露的信息则证实，他并非仅停留在口头警告层面，其管理的Scion资产管理公司正动用巨资 进行空头布局。 伯里还通过推文附带的图表进一步阐述其观点，他对比了Alphabet、亚马逊与微软在2018至2022年云业 务板块的增长态势与当前阶段的差异，暗指当前AI热潮的投资回报率远未达市场预期。这一论调与市 场上与日俱增的忧虑形成呼应：如同互联网泡沫初期对光纤领域的大规模过度投资，当前AI泡沫中的 头部企业未来或许可能遭遇崩盘危机。 具体来看，根据本周的一份证券公告，迈克尔·伯里已买入英伟达和Palantir ...

东吴证券最新研报指出，近期海外市场持续担心美股AI泡沫叠加美国科技股龙头财报表现分化，例如 谷歌云计算及搜索业务超预期，印证了AI工具推动科技巨头广告业务份额提升的说法，但是对比来看 Meta，虽然营收好于预期，但是由于Capex显著加速，市场担忧未来利润受到一定侵蚀，映射到港股方 面，投资者对科技持观望态度。不过，该机构认为，尽管美国科技龙头会影响港股AI科技交易节奏， 但从中长期看当前港股科技点位有吸引力。考虑科技龙头内卷接近尾声，该机构认为明年一季度港股 EPS会边际回升。 尽管短期承压，但从估值角度看，当前或许正是"危中有机"时刻。数据显示，截至11月4日，恒生科技 指数ETF(513180)标的指数最新估值(PETTM)仅为22.59倍，处于指数发布以来约26.83%的估值分位点。 换句话说，当前估值比历史上73%以上的时间都要便宜，已经进入历史低估区间。 从历史经验看，当市场陷入极度恐慌时，往往也是长线资金逆向布局的良机。尽管短期面临美股AI泡 沫论的情绪冲击，但AI产业革命的大趋势并未改变。港股科技板块作为中国AI产业的核心资产，在美 联储降息周期下有望迎来外资回流，叠加南向资金的持续增持，四季 ...
