特朗普签令,启动全新国家计划
Jin Rong Shi Bao· 2025-11-25 12:55
然而,无论是《赢得竞赛:美国人工智能行动计划》还是如今的"创世纪计划",特朗普政府想要发展AI 技术的雄心面临着现实因素的掣肘。值得注意的是,当前全球AI发展十分迅猛,但更好的性能需要更 多的模型、数据以及算力。然而,想要训练大模型,建设和发展数据中心,都离不开大量的能源消耗, 这种消耗大量能源的模式是不可持续的。 加拿大卡车自动驾驶公司Waabi的创始人兼首席执行官拉克尔.乌尔塔森曾表示,据估计,一个大型语言 模型(LLM)单次训练所消耗的电量相当于130户美国家庭一年的用电量。随着模型变得更加庞大,这一 数字还会继续增加。 更重要的是,大力发展AI对美国经济而言并非百利而无一害。对于美国的劳动力市场,有分析指出, AI的迅速发展和普及正在削弱劳动力需求。对于一些初级的入门岗位,都可以使用AI,这让很多刚毕 业的大学生很难找到合适的工作。 国金证券在《全景式扫描AI对美国经济的影响》研究报告中指出,2022年的AI横空出世产生了"影子财 政"的效果,而2025年行业头部企业开始缩圈,聚合产业资源并持续宣布长远的规划则更像是"影子财政 2.0"。对实体经济而言,AI支出的退坡和放缓对美国经济的打击要远胜于已经 ...

Zhi Tong Cai Jing· 2025-11-20 12:19
市场消息 美联储决策迷雾未散!迟来的9月非农数据难以照亮降息前景。美国劳工统计局将于周四发布9月份的非农就业数据,从而结束 因政府停摆导致的官方就业数据空白期——尽管这份数据提供的无疑是过时信息。该报告预计将显示非农就业人数增加5万 人,高于最初报告的8月份的2.2万人,但仍表明劳动力市场疲软。由于这些是9月份的数据,它们对试图在艰难局面中寻找方向 的政策制定者帮助有限,并可能被市场忽视。美联储主席鲍威尔最近将这种情况比作"在雾中驾驶",并告诫不要将进一步降息 视为板上钉钉。 AI热潮还在持续赋能!巴克莱看好大型科技股引领标普500指数突破7400点。巴克莱策略师将2026年底标普500指数的目标预期上 调至7400点,较该基准指数周三收盘位6642.16点有11.4%的潜在涨幅,理由是超大市值科技股的强势,以及尽管经济增长缓 慢,但货币和财政环境有所改善。7400点的目标较此前7000点的目标上调了5.7%。该行策略师还将标普500指数2026年的每股 收益目标从295美元上调至305美元,因为他们认为科技行业的利润增长将超过华尔街的普遍预期,"超大市值公司在宏观低增长 环境中继续表现出色,且人工智能竞赛没 ...

Core Viewpoint - The competition among U.S. tech giants for artificial intelligence (AI) dominance has intensified, leading to a surge in debt financing for data center construction, raising investor concerns about the sustainability of this trend [1][4]. Group 1: Debt Financing Trends - Amazon launched its first dollar bond issuance in three years, raising $15 billion, exceeding its initial target by $3 billion [3]. - Other tech companies are also heavily issuing bonds, with Alphabet raising approximately $17.5 billion in the U.S. and €7.5 billion in Europe, while Meta raised $30 billion in late October [3]. - Oracle plans to issue $38 billion in bonds to fund its AI infrastructure projects, contributing to a total of over $200 billion in corporate bonds issued by U.S. companies this year for AI-related infrastructure [3][4]. Group 2: Market Expectations and Concerns - Analysts estimate that global data center spending will reach nearly $3 trillion by 2028, with $1.4 trillion covered by cash flow from large U.S. tech companies, leaving a $1.5 trillion funding gap to be filled by other sources [4]. - The optimistic market outlook for AI revenue anticipates growth from $45 billion last year to $1 trillion by 2028, driven by demand from enterprises, public sectors, and individuals [4]. - Despite the robust cash flow and credit status of leading tech companies, doubts remain about the commercial viability of AI applications and the sustainability of investments in the sector [4]. Group 3: Risks and Market Reactions - If AI technologies fail to deliver expected returns in the coming years, heavily indebted companies may face significant losses, potentially impacting the broader economy [5]. - The current trend of shifting towards debt financing is reminiscent of the late 1990s internet bubble, raising concerns about the repayment of substantial debts incurred by tech companies [6]. - Recent market reactions include a sell-off in AI stocks, with Oracle's 30-year bonds dropping about 8% since their peak, indicating growing investor unease regarding the debt accumulation for AI infrastructure [6].

Zheng Quan Ri Bao Wang· 2025-11-17 13:05
本报讯 (记者毛艺融)11月17日,瑞银财富管理投资总监办公室(CIO)发表观点称,科技公司正在加大对人工智能 (AI)基础设施的投资,会利好AI、电力和资源主题相关股票。 "当前AI并非泡沫。尽管股市估值较高,但并未达到极端水平,这是因为过去几十年来,市场的构成发生了变化,愈来愈 偏重市盈率较高的板块,如IT和通信服务。"瑞银财富管理认为,当前的估值也远低于此前泡沫时期的水平,头部科技公司的 12个月远期市盈率为30倍,而1999年领先科技公司的市盈率则超过70倍。 "上周四科技行业领跌美国市场,周五仅小幅回升,因市场参与者仍对AI涨势的可持续性表示担忧。积压的官方经济数据 尚待公布之际,美联储政策前景的不确定性也令市场情绪承压。"瑞银财富管理表示,该机构仍然确信AI的结构性增长将继续 利好股票表现。 (编辑 李家琪 张昕) 瑞银财富管理认为,AI需求增长和变现速度有所提高。近期科技公司业绩持续表明对AI算力和服务的需求超预期。同时, 随着领先科技公司的资产负债表保持强劲,AI支出占全球GDP的比例适中,预计未来生产率的增幅将足以证明持续AI投资和相 关折旧的合理性。 该机构还提到,随着数据中心需求上升,A ...

上周美股全线回落,纳斯达克综合指数下跌超3%,创近七个月来最大跌幅。根据美国银行发布的最新 数据,面对近期科技股因估值担忧引发的指数调整,机构投资者正借鉴 "散户资金"的操作策略选择逢 低买入,而个人投资者则陷入犹豫。在市场板块轮动的背景下,关注估值风险的讨论依然火热。 机构入场抄底 美国银行股票交易部门数据显示,上周交易所交易基金(ETF)的净买入额达43亿美元,创下2022年12 月以来的单周最高纪录。 标普全球在周二发布的一份研究报告中指出,衡量市场情绪转变最显著的指标,是主要科技子板块的空 头头寸数据。目前,北美半导体及半导体设备品类下公司的空头利率已达0.285%,为今年以来的最高 水平。 美银全球研究部的分析师团队在周报告中指出,这一买入规模足以抵消个股的资金流出。但与近期趋势 不同的是,此次大举买入的主体是美银的机构客户 ——他们在此前一周还处于卖出状态;而今年以来 在股市回调期间始终稳步买入的个人投资者,此次却并未入场。事实上,这是自9月底以来,美银零售 客户首次在股市回调中选择观望。 近期,投资者似乎陷入两难:一方面担心错失AI相关投资机会,另一方面又忧虑市场可能出现类似互 联网泡沫时期的风 ...
