12 pieces from 9 publishers: Micron's fiscal Q4 and 2028 supply claims, Gemini 4 Argon, a silicon photonics foundry map, and a 5.33% US 10-year
On 2026-10-01 the nine research publishers tracked here published 12 pieces. Micron's fiscal fourth-quarter results dominate: FundaAI wrote a review, and TMT Breakout covered the print in a morning wrap and a podcast digest. Other pieces include FundaAI on Google's Gemini 4 Argon, PhotonCap on silicon photonics foundries, Cassandra Unchained on GPU depreciation, AlphaPick on Amazon, TMT Breakout's close-of-day wrap, a Macro Charts rates update, two personal-account pieces from James Bulltard and Irrational Analysis, and a Damnang navigation post. Every statement below is attributed to the publisher that made it, with the publisher's own numbers. Quant Data did not verify these numbers and takes no view on them.

"Points extracted" counts the discrete claims (numbers, theses, risks, catalysts, falsification points) pulled from each piece during ingestion. It measures how much a piece asserts, not how good it is.
What each piece said
AlphaPick · AMZN — Stock Buy: A Prime Opportunity In Commerce And AI
AlphaPick, writing as Seeking Alpha's Alpha Picks service, reports Amazon Q2 revenue of $200.6B (+20%) and operating income of $27.5B (+43%), with AWS backlog of $496B and AWS AI and custom-chip businesses each above a $25B annualized run rate. It cites a GAAP PEG of 0.22 versus a sector 0.54 and 48 upward, zero downward EPS revisions in 90 days. It names roughly $220B of 2026 capex as the main risk and gives no price target.
Cassandra Unchained · NVDA — Don’t Believe Your Lyin’ Eyes, GPU Depreciation & Useful Lives
Cassandra Unchained argues that Nvidia's 9/27 roadshow slide showing GPU residual values above its accelerated depreciation curve (B200 158%, H100 58%, A100 25%) is an 8-year DCF model from Silicon Data, not used-GPU prices. It attributes rising rentals (A100 +46.5% since late January, H200 +25% since May) to memory-driven server scarcity and compares the setup to 1968-70 computer leasing, when lessor stocks fell about 80%. It names no price target or timing.
Damnang — New here? Start with the article map
A navigation post rather than research. Damnang describes its Substack archive as 100+ articles and 413 reader questions (225 answered), with about 30% of articles free, covering HBM, co-packaged optics, glass substrates, EUV, and power and cooling. It mentions a possible Founding subscriber tier with datasets, forecasts and industry models, which it says is not confirmed. The post contains no tickers, valuations or investment conclusions.
FundaAI · GOOGL — Research|LLM: Gemini 4 Brings Google Back into Frontier Competition as Investment Accelerates
FundaAI says Google's Gemini 4 Argon, released 9/30, scores 53 on the Artificial Analysis index, level with GPT-6 Astra and below Opus 5.5 at 58. It lists pricing of $2/$10 per million tokens at introduction, rising to $4/$20, and Google Cloud revenue up 82% year over year with a $514B backlog. FundaAI is bullish on GOOGL, provided broader use confirms the benchmark gains, and on compute and networking infrastructure.
FundaAI · MU — Review|MU FY26Q4: Visibility Extends to 2028, Supply Tighter Than in 2026
FundaAI reviews Micron's fiscal Q4 2026: management says memory supply is tighter in calendar 2027 and 2028 than in 2026, with more than 75% of 2027 output locked by strategic customer agreements and prepayments. It cites 26 take-or-pay agreements, roughly $150b of remaining performance obligations and $32b of customer commitments. FundaAI models calendar 2027 EPS of $213, about 5x forward P/E, and is bullish on MU. FQ1 gross margin guidance sits 75bps below buy-side expectations.
Irrational Analysis · CRDO — Q3 2026 Consolidated Holdings, Performance, and Ideas
A quarterly review of the author's personal semiconductor account. Irrational Analysis reports 51.55% excess return versus SMH (target at least 30%), recovered from a low near $900K, all self-reported. It adds Credo (CRDO) to its second tier on a thesis favoring micro-VCSEL over microLED for slow-and-wide optical links, adds tape-drive maker QMCO to its speculative tier, and holds a split view on Cerebras: weaker before its lock-up ends, possibly strong from 2027H1 to 2028H1. The Credo shift rests on anonymous contacts.
James Bulltard · SPY — 10/1/26 Recap
A personal trading diary of an options seller, not research. James Bulltard says SPY was rejected at the 21-day EMA and closed under its 50-day average ahead of the next day's payrolls report, and cites the 100-day at 754 and the 200-day at 720. The author reports rolling short INTC puts from $115 to $110 for a $0.49 credit (250 contracts), lowering covered calls to $120, and closing short puts in MDB, MU and U to free margin.
Macro Charts — Market Update & Signals 10/1/26
Macro Charts notes stocks ignored September seasonality with tech leading, while rates are stressed: the US 10-year at 5.33% (highest since 2002), the UK 30-year at 6% (first time since 1998) and the France-Germany 10-year spread at 131bp. The author is contrarian: it says bond sentiment at the 1.3 percentile points to stabilization, expects a EURUSD bear-trap reversal toward about 1.16 in November-December, and adds Brazil to its watch list. Trade levels and sizing are not disclosed.
PhotonCap · TSEM — The Silicon Photonics Foundry Layer: Who Can Actually Make a PIC
PhotonCap maps who can make silicon photonics chips, arguing only six foundries can produce them at volume and that the scarcest input is Photonics-SOI wafers, where it puts Soitec at about 95% share. It cites Tower's SiPh run-rate of $680m (Q2'26) heading to $1bn in Q4, about $1.3bn of 2027 revenue contracted, and about $320m of prepayments and deferred revenue. It warns that 2027-28 capacity additions could turn scarcity into oversupply and a wafer-price reset in 2028.
TMT Breakout · LITE — TMTB EOD Wrap
TMT Breakout's close-of-day wrap for 10/1: QQQ +31bps, software +1.6% and semiconductors +1.4%, with the 10-year touching about 5.34% before closing near 5.24% and October-meeting hike odds falling to about 30%. It reports Accenture +15.8% after an $18.68B quarter, Synopsys +12.8%, and Coherent +10.9% on a Morgan Stanley thesis about FCC rules for optics. Other items include Micron +3%, Anthropic's targeted pre-Thanksgiving IPO and Broadcom -2.1% on a loan of up to $42B to Anthropic.
TMT Breakout · MU — TMTB Morning Wrap
TMT Breakout's pre-market wrap led by Micron's fiscal Q4: revenue of $54.23B versus Street at about $51B, FQ1 revenue guided to $60-63B and gross margin guided to 86.25% versus a buy-side 87-88%, with shares roughly flat. It relays 26 strategic customer agreements and RPO of about $150B, and says its read is that memory stays choppy but trends upward. It also covers Accenture's rebound, Gemini 4 Argon and a list of sell-side ratings on NVDA, AMZN, BE, CRDO and SNPS.
TMT Breakout · MU — TMTB Podcast Intel: Micron’s (MU) Mehrotra on the Quarter the Stock Shrugged Off, SK Hynix’s (SKHY) Valluri on the Memory Cycle, Altman on Dots, Airbnb’s (ABNB) Chesky on Agents, and More
A table of contents for TMT Breakout's podcast digest rather than analysis, at 337 words of mostly episode titles. The headline items are Micron CEO Mehrotra on a blowout quarter the stock shrugged off, 26 strategic customer agreements stretching to 2031 and supply tighter in 2027 and 2028, plus an SK Hynix executive on the memory cycle and a Meta Muse episode on 2 CPUs and 8GB per user. No financial figures or ratings are given.
Directional statements on the record
Each row is a dated fact: a named source expressed a direction on a named ticker. Where a publisher was relaying a broker's rating change, the originating voice is in the "via" column. None of this is a recommendation from Quant Data.

What would prove them wrong
Several publishers name the observation that would falsify their own view. Those are the most useful sentences in any research note, so they are collected here.
- AlphaPick · AMZN: Q3 operating income below the $22.5B low end of guidance would hurt the thesis; also watched are AWS backlog staying above $496B and any first downward FY1 EPS revision after 48 upward in 90 days.
- AlphaPick · AMZN: 2026 capex rising above about $220B with free cash flow turning negative.
- Cassandra Unchained · NVDA: If Silicon Data H100/A100/B200 rental indexes keep rising after DRAM and GDDR6 prices fall, the memory-scarcity explanation is wrong; Cassandra expects the reversal no earlier than 2027.
- Cassandra Unchained · NVDA: If Nvidia's supply commitments keep rising from $279B and the shortage lasts to fiscal 2028 as Nvidia's CFO says, the 2027 timing is pushed out or disproved.
- FundaAI · GOOGL: Whether Argon's Artificial Analysis score holds near 53 once opened to paid API and Ultra users, and whether the Terminal-Bench 4.0 gap of 9.0 points narrows.
- FundaAI · GOOGL: Whether Google Cloud growth stays near 80% and backlog stays above $514B.
- FundaAI · MU: Commodity DRAM contract prices turning negative quarter over quarter in FY27 would invalidate the continued-price-rise view.
- FundaAI · MU: Strategic customer agreement coverage stalling near 35% instead of moving toward about 50%, or FY27 capex clearly above $50b with equipment catching up to building spend, which FundaAI reads as supply arriving earlier.
- Irrational Analysis · CRDO: A Credo uVCSEL roadmap at OCP would support the author; a uLED demo with raw BER of 1e-12 per lane would disprove the thesis.
- Irrational Analysis: Cerebras trading around its lock-up expiry (about December) and whether it moves to 3D SRAM wafer hybrid bonding by 2027H1.
- James Bulltard · SPY: A 10/2 close that does not recover the 50-day average keeps the warning in place; a 1% drop loses the 100-day at 754, with the 200-day at 720 below.
- James Bulltard · SPY: Payrolls above 150k or at or below 25k are read as negative for the market; 50-100k is the author's preferred outcome.
- Macro Charts · EURUSD: If EURUSD breaks lower without a next-day reversal, the bear-trap thesis fails.
- Macro Charts: If the US 10-year keeps rising after the ISM and payrolls data instead of stabilizing from 5.33%, the bond reversal view is wrong.
- PhotonCap · TSEM: Tower's Q3 report in November against its $520m guide, SiPh run-rate toward $1bn, and prepayments staying above $320m; gross margin falling below 30% would signal the 2028 wafer-price reset.
- PhotonCap: Soitec loading crossing 60-70% by end-2027 forcing expansion, or any second source qualified for 300mm Photonics-SOI; also whether UMC names a second SiPh customer beyond SILITH by end-2027.
- TMT Breakout · MU: Whether FQ1 gross margin holds at or above 86.25% and recovers from FQ2, whether strategic customer agreements are honored if spot prices fall, and the buyback size disclosed from 12/9.
- TMT Breakout · LITE: The 10/12 OCP conference: if Lumentum and Coherent cannot hold the $1k breakout or the FCC details disappoint, the optics rally thesis is undercut.
- TMT Breakout: A 10-year yield above 5.34% with prices paid still rising would pressure high-multiple tech; 10/28 FOMC hike odds staying near 30%.
- TMT Breakout · AMZN: AWS raising GPU reservation prices about 15% on 10/7 is a stated checkpoint for the tight-supply thesis.
