Holdings Breakdown
CRDO closed at $231.35, down 1.48% on the session. A Seeking Alpha analyst initiated coverage with a Sell rating today, arguing that Credo's valuation has run ahead of fundamentals given limited contract visibility and meaningful customer concentration in its hyperscaler-driven revenue base. The note surfaces a structural concern: rapid revenue growth tied to a narrow set of large cloud customers can compress multiples quickly if order cadence softens.
AMZN closed at $260.11, down 2.16% on the session. The session's pressure comes despite a broadly constructive fundamental backdrop: AWS has accumulated a $496 billion committed backlog, roughly three years of revenue at current run rates, with CEO Andy Jassy noting demand cannot be fully served through 2027 and 2028 bookings already materializing. Amazon is directing a $220 billion capital expenditure program this year primarily toward data center expansion. Separately, Anthropic's annualized revenue hit $65 billion in July, up 600% year-over-year, directly benefiting Amazon given its $13 billion equity stake and a $100 billion cloud services commitment tied to the partnership.
Also moved: MSFT -0.65%, NVDA -0.25%, IONQ -4.22%, AAPL -1.75%, JPM -1.60%.
Watchlist
MRVL closed at $251.01, up 5.79% on the session. The session's surge follows Marvell's announcement of a major custom silicon partnership with Alphabet, under which Google's deal could unlock a staggering opportunity that JPMorgan estimates at roughly $120 billion for the company. The structure includes an equity component: Marvell's SEC filing discloses entry into a material definitive agreement alongside unregistered sales of equity securities, consistent with reporting that Alphabet can acquire up to $12.2 billion in MRVL shares via warrants tied to the deal.
Also moved: ARM +0.55%.
Bottom Line
Thursday's session closed the portfolio lower, with IONQ sliding -4.22% and AMZN retreating -2.16% on company news, pulling the seven-equity book down across the board.
