Holdings Breakdown
AMZN closed at $266.43, up 3.97% on the session. The day's surge follows a Motley Fool report that Citadel trimmed Nvidia, Broadcom, and Micron while adding Amazon exposure, a rotation Ken Griffin's fund is framing as a preference for companies showing tangible returns on AI infrastructure. That thesis gets direct support from a separate report noting AWS agreed to purchase an additional 2 million Nvidia GPUs over two years, underscoring continued heavy capital deployment into cloud infrastructure even as Amazon's own custom silicon already runs at a reported annual revenue run rate of tens of billions.
MSFT closed at $513.53, up 1.68% on the session. The sharp one-month surge has been broad-based across large-cap technology, with Microsoft carried alongside peers like Nvidia and Apple in a rally that has lifted Nasdaq-heavy vehicles well above broader market benchmarks over the past year. No company-specific catalyst is evident in today's session beyond that macro momentum.
NVDA closed at $217.55, down 4.57% on the session. The afternoon sell-off was macro-driven: Federal Reserve Chair Kevin Warsh delivered a hawkish Jackson Hole speech signaling rate cuts are unlikely in 2026 and leaving rate hikes on the table, sending two-year Treasury yields sharply higher and growth-oriented names like NVIDIA disproportionately lower. Earlier in the session, sentiment had been buoyed by news that Amazon Web Services agreed to purchase an additional 2 million NVIDIA GPUs over two years, a deal that underscores continued hyperscaler demand even as AWS generates substantial revenue from its own custom silicon. Dell's disclosure of a record AI server backlog and raised fiscal 2027 AI server guidance also reinforced the broad infrastructure spending environment that underpins NVIDIA's customer pipeline.
Also moved: CRDO -3.12%, IONQ -7.68%, AAPL +1.63%, JPM +0.96%.
Watchlist
MRVL closed at $216.62, down 10.28% on the session. Marvell filed an 8-K reporting results of operations on Thursday, and Friday's sharp pullback came despite the company beating expectations, as semiconductor stocks broadly sold off amid caution following recent rallies and signals of potential rate hikes from Fed Chair Kevin Warsh at Jackson Hole. The broader market edged modestly higher on the session, making Marvell's decline a sector-specific reaction rather than a macro-driven one.
ARM closed at $239.05, down 6.33% on the session. Today's pullback follows a sustained run driven by Arm's royalty-licensing model, which collects fees across smartphones, data centers, and automotive platforms rather than selling chips directly. Arm's energy-efficient architecture has positioned it as a broad beneficiary of AI adoption, but the stock carries a forward price-to-sales multiple roughly eight times the semiconductor industry average, leaving it sensitive to any shift in growth expectations.
Bottom Line
Friday's session left this portfolio split, with IONQ sliding -7.68% and NVDA falling -4.57% on company news pulling against gains from AMZN, which rose +3.97% on its own company news, and MSFT adding +1.68% to close the week on a positive note for those two names.
