Holdings Breakdown
AMZN closed at $265.84, up 2.46% on the session. The session's gain followed a morning report confirming that Amazon's AWS AI business has crossed a $25 billion annualized revenue run rate with triple-digit year-over-year growth, alongside overall AWS segment growth of 37% last quarter. The core question surrounding the valuation is whether AWS can sustain margin expansion as it continues scaling its AI infrastructure, a trajectory analysts note would need to hold through 2031 to support the current forward earnings multiple.
JPM closed at $357.26, down 1.65% on the session. At 70, Jamie Dimon is approaching retirement after two decades leading JPMorgan, and the bank has already elevated Doug Petno and Troy Rohrbaugh to co-presidents as part of a structured succession plan. The dual co-president structure signals a continuity-oriented handoff rather than a sharp strategic pivot.
NVDA closed at $217.56, down 0.99% on the session. The session's headline was Jensen Huang's agreement with Noetra, a 44-company Japanese industrial consortium, to deploy Nvidia as the compute backbone for AI factory floors, backed by a $6.1 billion Japanese government subsidy commitment. On the other side of the ledger, Coatue Management's Philippe Laffont has trimmed his Nvidia position by roughly 88% since Q1 2023, selling in 12 of the last 13 quarters, citing competitive pressure from hyperscalers building proprietary AI silicon. Nvidia's next earnings report has not been publicly scheduled as of this session.
Also moved: CRDO -4.53%, IONQ -1.72%, AAPL +2.19%, MSFT +0.56%.
Watchlist
MRVL closed at $237.27, up 9.85% on the session. Today's surge was driven by Marvell landing a major custom silicon deal with Alphabet for AI and networking applications, a win that extends the company's growing roster of hyperscaler customers. Alongside the Alphabet news, Marvell raised its FY27 revenue outlook to $11.5 billion, reflecting accelerating demand for its optical interconnects and custom silicon across data center infrastructure. Nvidia's public endorsement of Marvell's data center connectivity role, also surfacing today, added a second layer of industry validation to the session's momentum.
Also moved: ARM -1.57%.
Bottom Line
Wednesday's session left the portfolio's equities pulling in opposite directions, with AMZN climbing +2.46% on company news while JPM slid -1.65% on its own developments, leaving the overall picture mixed heading into Thursday.
