BlackRock大举增持AMD至9.05%背后:三大机构季度末调仓透视
📊 本文涉及标的速览
全球最大资管机构贝莱德(BlackRock Inc.)于2025年年末对超威半导体(AMD)的持仓动作,折射出机构资金对AI芯片赛道态度出现显著分化。SEC最新披露的13F文件显示,截至2025年12月31日,BlackRock持有的AMD股份占流通股比例达9.05%,较上一季度环比增持8.2%;而同期摩根士丹利(Morgan Stanley)将持仓降低16.7%,持股比例降至1.54%。挪威主权基金(Norges Bank)则逆势加仓5.5%,持股比例升至1.41%。三家头部机构在AMD上的操作方向形成鲜明对比,为观察专业资金动向提供了重要窗口。
资金主体画像:三大机构立场分歧
贝莱德此次增持后,其在AMD的持股比例已接近10%的机构持仓重要临界值。作为全球管理规模超过10万亿美元的资管巨头,贝莱德的配置决策通常被视为对赛道长期前景的战略性判断。值得注意的是,贝莱德在科技板块的持仓向来以“一篮子”方式布局,其对AMD的增持可能既包含对GPU市场占有率的乐观预期,也可能是对该公司在数据中心市场挑战英伟达叙事下的选择性配置。
相比之下,摩根士丹利的减持动作更为激进,16.7%的环比降幅在大型机构中属于明显的边际撤退。摩根士丹利曾在2024年将AMD列为“首选标的”,此番减仓可能反映了该行自营部门或客户组合对短期估值性价比的重新评估。从持仓比例1.54%来看,摩根士丹利在AMD的配置已从积极持有转向边缘配置,显示出其对AMD与英伟达在AI加速器市场竞争格局的谨慎判断。
挪威主权基金的逆向增持则更具政策信号意义。作为专注长期结构性增长的超大型基金,Norges Bank对AMD的增持往往被视为对半导体行业长期价值的锚定。该基金持仓比例从1.34%提升至1.41%,增幅相对温和,但方向明确。
AMD近期行情表现与估值区间
从盘后行情数据观察,AMD在最新交易日并未出现显著异动,当日涨跌信息未纳入本次快照范围。回顾近期市场表现,AMD股价在2025年上半年经历了一定波动,整体呈现区间震荡格局。
从同业对比来看,AI芯片板块内部出现明显分化:英伟达(NVDA)当日上涨2.29%,股价报$225.83;Meta Platforms上涨2.26%,而特斯拉(TSLA)更是录得2.73%的涨幅。科技权重股的普遍回暖为AMD提供了相对友好的板块环境。
从估值角度分析,AMD作为CPU和GPU双主线的半导体设计公司,其市销率(P/S)和市研比在行业内处于中等偏上水平。市场对AMD在数据中心市场能否持续扩大份额的关注度较高,这也是机构资金产生分歧的核心因素。
同类机构调仓历史对照
机构对AMD的大幅增持并非孤例。回顾2023年至2024年间,贝莱德曾在多个季度对AMD进行过类似的阶梯式增持,单季增幅通常维持在5%-10%区间内。2023年Q3,贝莱德曾一次性将AMD持仓提升超过12%,彼时正值AMD发布MI300系列AI芯片的前夕,市场对其数据中心业务的预期达到阶段性高点。
与之相对,摩根士丹利对AMD的减持在历史上也曾多次出现。2024年Q1,该行曾将AMD持仓削减近20%,彼时正值半导体板块估值回调期。摩根士丹利的操作风格通常倾向于在股价阶段性高点进行利润兑现,这与此次16.7%的减持幅度形成呼应。
Norges Bank的增持则呈现出明显的“逆向布局”特征。该基金多次在AMD股价承压期间加码持仓,持股周期通常在2-3年以上,属于典型的长期机构股东。其增持时点与贝莱德往往呈现一定的互补性,这在一定程度上起到了平滑筹码结构的作用。
后续仓位变化的关键观察窗口
对于AMD的后市走向,投资者可重点关注以下观察维度。首先,13F持仓数据具有45天报告期的滞后性,当前披露的是截至2025年12月31日的持仓快照,实际仓位可能在2026年初已发生变化。其次,Q1财报发布前通常会有机构进行预判性调仓,AMD计划于近期公布最新业绩,市场预期将成为机构持仓变化的重要催化剂。
此外,需关注贝莱德是否会突破10%持股比例的重要临界值。一旦接近这一阈值,将触发披露义务门槛的升级,可能引发市场对“潜在收购意向”或“大股东行动”的联想。从历史经验来看,机构持仓集中度显著提升往往伴随着波动率的放大。
从期权市场角度观察,AMD近期看跌/看涨期权比(Put/Call Ratio)若出现异常变化,也可能预示机构对短期方向的分歧加剧。衍生品市场的资金流向与现货持仓变动共同构成判断机构真实意图的完整图景。
总体而言,三家顶级机构在AMD持仓上的分化操作,既反映了专业资金对AI芯片竞争格局的深度博弈,也体现了不同资管机构在投资策略与风险偏好上的本质差异。AMD能否在数据中心市场持续扩大份额,将是决定这些机构资金最终走向的核心变量。后续季度13F披露将成为验证当前持仓动向延续性的关键窗口。

In amd, you have to turn on TearFree in xorg.conf, but you can then avoid screen tearing with and without compositors. I have no idea why this is not turned on by default.
$SMCI $AMD $META $MSFT Heres the others
Here are some numbers: I bought a windows box with misconfigured dram timings (bios bug). I never would’ve been able to root cause it under windows (certainly not with builtin tools), but dmidecode on linux made the problem obvious. Fixing the timings fixed crashes in amdgpu that windows users widely reported (with no diagnosis), and increased frame rates by 30-50%. Anyway, if …
I've been gaming on Linux since 2020 on an Nvidia GPU with no problems, including some AAA titles like Overwatch and Halo.
Market has been ignoring WAR; then CPI then HOT PPI This stock market becomes a CASINO by TRUMP Baed on his mood and trips buy CALL /PUT So many retail got lucky with AI pumps. Overall THIS MARKET is OVERBOUGHT ! GL $SPY $QQQ $MU $GOOGL $NVDA
Nvidia for me on Linux (Fedora 43 - KDE Plasma) for about half of the titles I play works flawlessly, although the other half of the games seemingly have issues. I encounter a few games with frame pacing issues, otherwise not present on Windows. Shader compile time is longer than on Windows. Occasional crash in some games, etc. Windows has issues too. It's not perfect, although…
>Does the financial markets still expect them to far out-earn Volkswagen and Toyota any time soon, we've been waiting for like a decade already?? These capital heavy industries operate on 30+ year timelines, a decade isn't sufficient time. Revenues are not the end all, be all. Profit and profit margin, along with revenue trends provide a more complete picture. And the most sign…
$NVDA $QQQ $TSLA $SPY this is good Fud and made me lol However It’s actually not protocol for presidents to meet at the airport. Foreign Minister first, then Xi.
I have no idea where you get this impression. Tesla is no where close to the majority (or even plurality) of fully autonomous self driving miles. Waymo is dramatically safer (less injuries, not quite enough data yet to be certain about fatalities, but they are lower than average, we just can't yet claim statistical significance) than human drivers. I haven't seen good stats on …
That works when you already have an established connection with someone, but it doesn’t work so well for making new connections. I’ve deleted all my Meta accounts and other social media accounts and have lost touch with many people and find it much harder to meet new people. Personally, I accept that tradeoff but can see how others wouldn’t (or can’t).
I feel like the suggestion to just delete your Meta account is unhelpful and even harmful in some situations. I know a lot of us in this field don't mind having a small social circle, but for us that struggle to even have that, or that the process of doing that, requires you to be as open and reachable as possible to make it easier to create or maintain friendships, this often …
