Seven research notes from seven publishers: FCC optical transceiver rules, memory price hikes, China liquidity, and a stack of sell-side rating changes

On 2026-10-02 the seven research publishers tracked here published seven pieces. TMT Breakout issued a morning wrap covering AI compute, memory pricing and sell-side rating changes. FundaAI wrote on reported FCC rules for Chinese optical transceivers, and Damnang on optical test equipment. AlphaPick posted a weekly portfolio recap, Capital Wars a macro note on China's liquidity, Macro Charts a chart-based market update ahead of the payrolls release, and James Bulltard a trading recap built around unusual options activity. Every statement below is attributed to the publisher that made it, using the publisher's own numbers. Quant Data did not verify these statements and takes no view on them.

What was published

"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.

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.

Numbers the publishers put on the record

• AlphaPick: 10-year Treasury yield peaked at 5.34%, the highest since 2002, and closed near 5.24%.
• AlphaPick · MU: Fiscal Q4 revenue $54.23B, up 379% year over year; adjusted EPS $33.42, up 1,003%; forward P/E at a 73% discount to the sector.
• AlphaPick: Alpha Picks returned 4.36% over the past month versus 0.29% for the S&P 500.
• Capital Wars: China debt-to-liquidity ratio about 1.0x versus long-run equilibrium about 0.75x; liquidity needs to rise about 33% to return to equilibrium (Japan about 60%).
• Capital Wars: PBoC liquidity is about 2x its 2019 level, roughly $3 trillion of added liquidity; bond yields imply about 1-2% real growth versus official GDP of about 5%.
• Damnang · AEHR: Aehr H2 orders $97.9M versus the $60-80M expected; FY27 silicon-photonics share guided at 15-20%; market cap about 10x modeled 2030 revenue.
• Damnang: Scale-up optical-engine test market about $2B a year; with 18 engines per package, 99% per-engine yield gives 83.5% package yield and 98% gives 69.5%.
• FundaAI · LITE: Reported framework: at least 65% US-company content by bill-of-materials value; 3.2T initial ramp in 2028, broad adoption around 2029; Buy American precedent 65% for 2024-28 rising to 75% from 2029.
• James Bulltard · SPY: A close above 775 is the level needed to confirm a breakout; lower highs since early August.
• Macro Charts · SPY: Key support $760; corporate buyback authorizations $1.3 trillion through 9/29, 8% faster than the 2025 record pace; bond sentiment at the 1.1st percentile.
• TMT Breakout · MU: KB Securities: 4Q26 DRAM up 10-15% quarter on quarter, NAND up 15-20%; SSD bit demand up 80% year over year.
• TMT Breakout · MU: Samsung reportedly proposing 2027 HBM4 pricing in the mid-to-high $4 per Gb range versus $1.50 for HBM3E; TrendForce forecasts 2027 HBM ASP up 121%.
• TMT Breakout · AVGO: Bloomberg-reported $60B financing for Anthropic and others: $42B senior secured and $18B subordinated.
• TMT Breakout · META: Needham: off-balance-sheet obligations of about $628B at 6/30/26 lift FY27 EV/revenue from about 6.15x to about 8.32x.

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: The 10/14 September CPI and 10/15 retail sales and PPI prints, and the 10/27-28 FOMC, as tests of whether inflation keeps cooling and a December hike stays priced.
• AlphaPick: Whether the 10-year yield falls below 5% or breaks above 5.34% again.
• Capital Wars: Whether the 10-day moving total of daily PBoC liquidity resumes its post-2022 expansion; continued stalling delays the thesis.
• Capital Wars: Whether gold, industrial metals and oil strengthen before Chinese equity indices and official data; the opposite order weakens the sequencing argument.
• Damnang · AEHR: Aehr's 10/5 fiscal Q1 report: silicon-photonics share above the 15-20% guide with continued orders would support; a long gap in orders would not.
• Damnang · FORM: Whether FormFactor's 2026 CPO revenue outlook rises above $20M and double-sided probing qualifies for volume production by mid-2027; stagnation would lead Damnang to revise down.
• Damnang · VIAV: Whether Viavi's CPO revenue accelerates separately from 1.6T pluggables and its network and service enablement gross margin stops declining.
• FundaAI · LITE: Publication of the FCC rule text: the 65% denominator, the definitions of US company and US-made. A Buy American-style 65%/75% plus US-manufacture test would undercut the milder thesis.
• FundaAI: Progress of the Communications and Technology Transparency Act and the Senate optical-module bill that names InnoLight and Eoptolink.
• James Bulltard · SPY: A close above 775 confirms the breakout; otherwise the author treats the move as a weak rally within the range.
• James Bulltard · FCX: A break above 80.24 is the upside marker; a move below 65, the rising 200-day line, is where the author would be willing to hold stock via short puts.
• James Bulltard · AMZN: A decline below 230 is the level at which the author would hold a full-size position.
• Macro Charts · SPY: A close below $760 invalidates the bullish setup; breadth making new lows below the 2022, late-2023 and April 2025 troughs would also fail the thesis.
• Macro Charts · IWM: Whether the oversold-sector reversals hold after the payrolls reaction, and whether 2-year and 5-year yields and rates volatility keep falling below March highs.
• TMT Breakout · MRVL: Marvell Investor Day on 10/6: whether the long-term model reaches about $45B revenue and about $19 EPS by FY31, as Piper expects.
• TMT Breakout · CLS: Celestica's 10/27 analyst day: whether 2027 revenue moves toward $40B versus Street $35.7B, per Bernstein.
• TMT Breakout · MU: Whether Samsung, SK hynix and Micron settle 2027 HBM contracts near the reported HBM4 pricing above 3x HBM3E.
• TMT Breakout · NVDA: Whether GPU-collateralized loans end up requiring Nvidia guarantees or investment-grade customer contracts, per the Reuters report relayed.
