周三美市盘前走高重点谈量子股为什么突然节节败退

联合早报01-08

黄仁勋说：“如果你认为量子电脑需要15年才会非常有用，我觉得那可能把它说得太早了。但是它也不至于要等到30年才会变得非常有用。如果说20年，我想我们都会比较认同吧。” 市场投资者隔夜的反应，似乎反映出他们听了黄仁勋所讲的话后，对量子计算进步时间重新进行评估。盘前交易重点：美国华尔街股市主要股指期货在星期三（1月8日）回弹。在7时截稿时，标准与普尔500指数期货上升20.40点或0.35％，报...

Corp股价就在隔夜盘后下挫了15.45%；D-Wave Quantum Inc股价跌了14.14%、Quantum Computing Inc也下滑12.86%；Rigetti Computing跌了将近13%；SEALSQ Corp和IonQ股价也双双退低约11%。\n\n在美国银行全球研究部将特斯拉（Tesla）的股票评级从“买入”下调至“持守”后，特斯拉的股价在隔夜就下跌了4%。该股在今晚盘前稍做回弹。在截稿时，特斯拉股价上升0.85%，报397.72美元。另外，美国国家公路交通安全管理局也对特斯拉新的“实际智能召唤”功能（Actually Smart Summon Feature）展开调查。这个功能让特斯拉车主在停车场召唤他的电动车自动驾驶到他身边。\n本星期较早时候，美国宣布了首例禽流感死亡病例。因为疫苗制造商莫德纳（Moderna）是目前正在开发H5N1禽流感疫苗的少数制药公司之一，因此该公司的股价在今晚盘前上涨5.03%，截稿时报49.92美元，延续了隔夜上涨12%的向上走势。\n美国最大蛋商Cal-Maine Foods公布的第二财季盈利和营业额均超出市场分析师的预期。公司表示，“由于带壳鸡蛋的供应下降，本财年鸡蛋价格预料会继续上涨”。该股在今晚盘前上升3.78%，报107.60美元。\n星期三下文我们来看看像Quantum Corporation的量子股为什么突然节节败退。今晚盘前Quantum Corporation股价下挫17.60％，截稿时报37.17美元。\n盘前活跃股按序：英伟达（Nvidia）、Plug Power、Palantir Technologies、Lucid Group和特斯拉。截稿时，这五只活跃股的股价起落不一。\n\nQuantum Corporation\n黄仁勋是在2025年消费电子展（CES 2025）的分析师问答会上，在回答分析师对量子股的询问时说，“非常有用”的量子电脑可能还需要几十年后才能真正起到作用。此话一出，所有量子股的股价即刻暴跌。\n黄仁勋也说，虽然量子计算对于小数据和大计算任务有效，但是由于它是基于微波的通信，所以会难以处理大数据。他强调了传统的电脑纠错的必要性，并将英伟达定位为传统量子计算领域的重要参与者。英伟达已与全球几乎所有量子计算公司合作，而且把自己的计算设备架构平台（Compute Unified Device Architecture，简称：CUDA）扩展到量子应用方面。\n（纳斯达克证券交易所代码：QMCO）\n\n  黄仁勋认为量子电脑要等到大约20年后才会真正有用。（法新社）\n \n\n\n\n\n最近士气如虹的量子股票在隔夜盘后突然全面节节败退。\n\n星期三（1月8日）重点：","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"symbols":[],"gpt_button":0},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
