What each piece said
Damnang — How HBM4 Is Changing Competition Among the Three Memory Companies
Damnang analyzes the HBM4 memory landscape, expressing a preference for Samsung and Micron over SK Hynix. The publisher highlights Samsung's vertical integration advantages and rumors of AMD and OpenAI orders, while noting SK Hynix faces reliability issues with TSMC base dies and high customer concentration with Nvidia at 93%.
FundaAI — Deep|Optics: OCS Content per Accelerator Grows with Each Generation as Demand Widens Beyond Google
FundaAI forecasts that optical circuit switch (OCS) demand will expand beyond Google, with Nvidia adopting OCS after late 2028 when scale-up domains exceed eight racks. The publisher projects global OCS demand will surpass $20 billion by 2030, with Lumentum's OCS revenue exceeding $2.5 billion in 2027.
FundaAI · ASML — Preview|ASML 26Q3: Raising EUV Shipment Expectations Again
FundaAI previews ASML's 26Q3 results, raising its 2027 and 2028 EUV shipment forecasts to 100 and 125 units, respectively. The publisher attributes this to easing capacity bottlenecks and strong memory demand, with Micron's FY27 capital expenditure implied to exceed $50 billion.
FundaAI · MRVL — Research|MRVL: Investor Day Targets Move Closer to Our Forecasts
FundaAI reviews Marvell's investor day, noting its CY30 revenue target of $80 billion and non-GAAP EPS target of over $30 align with FundaAI's forecasts. The publisher highlights Marvell's custom silicon expansion, scale-up optics growth, and a steep switching ramp targeting $10 billion by FY31.
Irrational Analysis · MRVL — Marvell 2026 Investor Day: Irrational Recap
Irrational Analysis provides a critical recap of Marvell's investor day, maintaining a bearish stance relative to Broadcom. The publisher praises Marvell's dense SRAM and die-to-die PHY but questions its 2030 targets, thin-film lithium niobate technology, and the economics of its new memory expander product.
James Bulltard — 10/7/26 Recap
James Bulltard recaps the day's market action, noting SPY's gap down after a breakout and rising interest rates, with the 30-year yield hitting 5.7%. The publisher details several large-cap options trades, including bullish call purchases on AMD and Chevron, and a bullish put sale on Boeing.
Macro Charts — Market Update & Signals 10/7/26
Macro Charts reports that the S&P 500 achieved its 28th all-time closing high of the year, with momentum expanding across multiple sectors. The publisher notes that bond sentiment fell to the 0.81 percentile, suggesting a classic reversal may be imminent, led by high-yield bonds.
TMT Breakout — TMTB EOD Wrap
TMT Breakout wraps up the trading day, noting QQQ fell 0.25% with semiconductors and software underperforming. The publisher highlights memory stock rotation, a 24-year high in the 10-year Treasury yield at 5.35%, and various corporate developments including Uber's $2.3 billion acquisition of ezCater.
TMT Breakout — TMTB Morning Wrap
TMT Breakout's morning wrap highlights rising yields weighing on markets and reports that SpaceX is seeking $40 billion to purchase Nvidia chips. The publisher relays several sell-side rating changes, including TD Cowen's upgrade of Marvell and Evercore's upgrades of NetApp and Microsoft.
TMT Breakout — TMTB Podcast Intel: SemiAnalysis’s Patel and Nanos on AI’s Payback Math, Marvell’s (MRVL) Murphy on Custom Silicon and Optics, Figma’s (FIG) Field on the Design Agent, The Circuit on the Memory Cycle
TMT Breakout summarizes recent industry podcasts covering AI capital expenditure payback math, custom silicon, and memory cycles. The publisher highlights SemiAnalysis's discussion of Nvidia's $588 billion in off-balance-sheet backstops and Broadcom's reported $42 billion loan commitment to Anthropic.

Are these Quant Data’s numbers?
No. Every figure on this page is attributed to the publisher that stated it and is reproduced as stated. Quant Data did not verify them. The only Quant Data numbers on the page are the counts of pieces and statements, and the settled options positioning shown for tickers that have a max pain page on this site.
Is a "bullish" entry in the statements table a recommendation?
No. The table records that a named source expressed a direction on a named ticker on a dated day, the way a clippings file would. It is not a signal and not advice. It exists so that the statements can be checked against what prices did afterwards.
