Holdings Breakdown

AAPL closed at $305.26, up 1.00% on the session. The session's gain comes amid commentary on Apple's path to a larger valuation milestone, with analysts noting that rising memory chip prices could pressure margins under CEO John Ternus as the company competes with Alphabet for the second spot in the race to a five-trillion-dollar market cap. Alphabet is cited as better positioned for that milestone given AI-driven cloud momentum and a lower valuation relative to operating cash flow.

AMZN closed at $265.13, down 0.80% on the session. Today's pullback came on no major corporate news, leaving analysts to focus on Amazon's structural growth story. AWS reported 37% year-over-year growth and carries a backlog approaching $500 billion, while digital advertising expanded 26% year over year, the two segments increasingly central to the company's margin profile. Founder Jeff Bezos retains roughly 900 million shares, a stake worth approximately $245 billion, though any planned share sales could introduce periodic selling pressure.

JPM closed at $363.11, down 0.57% on the session. Today's modest pullback follows a strong run since JPMorgan's last earnings report roughly 30 days ago. An intrinsic value analysis using the Excess Returns model suggests the shares trade at a discount to fair value, though traditional valuation metrics present a more mixed picture. Separately, JPMorgan's research desk initiated Salesforce at Overweight, arguing that AI-related concerns are overblown and that the stock is pricing in deceleration the analyst team does not expect.

MSFT closed at $496.88, up 0.90% on the session. The available headline addresses Amazon's capital-allocation posture rather than any Microsoft-specific development, leaving today's move without a disclosed company catalyst.

NVDA closed at $225.30, up 0.54% on the session. Despite strong profitability across the sector, major chip stocks including NVIDIA keep dividend yields below 1%, with cash flows directed instead toward stock buybacks and capital investment in manufacturing capacity rather than income distributions.

Also moved: CRDO -0.81%, IONQ -0.49%.

Watchlist

MRVL closed at $222.18, up 2.35% on the session. Today's move was driven in part by a rating upgrade citing a Q2 revenue and margin rebound alongside management's raised long-term outlook for data center demand. Broader context came from Lumentum's CEO, whose comments on the AI networking buildout reframed the scale of the opportunity for companies like Marvell in optical and custom silicon. Marvell is scheduled to report this August in close proximity to Nvidia and Broadcom, meaning the earnings window will offer a read on AI infrastructure demand across the sector simultaneously.

ARM closed at $278.65, up 2.49% on the session. Today's move followed Arm posting its third straight year of revenue growth above 20%, cementing its position as the dominant compute platform of the AI era. The broader catalyst is a BofA Securities projection that AI-agent-driven server CPU demand could reach $210 billion by 2030, with Arm named alongside AMD and Intel as a primary beneficiary of that shift. Analysts framing the thesis suggest Arm could be the largest beneficiary of a structural move toward CPU-centric AI infrastructure, a narrative that pushed the stock sharply higher intraday before it settled off the session peak.

Bottom Line

Thursday's session left the portfolio in mixed territory, with AAPL climbing +1.00% and MSFT adding +0.90% on company-specific news, while AMZN slipped -0.80% and JPM edged down -0.57% on their own respective developments.
