"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

Capital Wars — Understanding The Bond Sell-Off

Capital Wars analyzes the recent bond sell-off, arguing it is driven by strong nominal economic growth rather than fiscal panic. The publisher estimates the US Treasury term premium is currently around -50 basis points, suggesting yields are high despite an unusually low risk premium.

Cassandra Unchained — Abridged Version Foundations: Performance in the Next Bear Market & the Caldera Under S. Park & Wall

Cassandra Unchained highlights extreme market narrowness, noting that when the S&P 500 hit a record high on October 6, 2026, its Bear Market Ratio reached 55%, with 406 of 503 members trading more than 10% below their 10-year highs.

FundaAI — Deep|LLM: Enterprise AI Adoption Survey (Vol. 6) - In Our Sample: AI Spending Growth Expected to Slow; Routine Work Shifts to Lower-Cost Models

FundaAI presents its sixth enterprise AI adoption survey, finding that AI spending growth is expected to slow at five of six surveyed companies. The publisher reports that companies are optimizing costs by matching tasks to lower-cost models and self-hosting open-weight models.

FundaAI — Research|LLM: DeepSeek V4.1-Flash-1017 Reaches the Top Tier of Open-Weight Models, Still Behind Proprietary Frontrunners

FundaAI reviews DeepSeek's V4.1-Flash-1017, placing it in the top tier of open-weight models alongside Kimi K3 and MiMo-V2.6 Pro. However, the publisher notes it still trails proprietary leaders like Opus 5.5, which scores 58 on the Artificial Analysis Intelligence Index.

FundaAI — Weekly|Anthropic ARR, Neocloud Credit Risks, TSM & ASML, Muse Wonder, Physical AI, Enterprise AI Spending, BE

FundaAI highlights rising credit risks in the AI buildout, noting CoreWeave's bond yields climbed to 15% and its five-year CDS reached 1,195 basis points. The publisher also reports Anthropic's September exit ARR reached approximately $70 billion, trailing expectations.

Irrational Analysis — OCP Global Summit 2026: Irrational Recap

Irrational Analysis recaps the OCP Global Summit 2026, criticizing integrated laser NPO designs and Marvell's 400G SerDes demo for using waveform averaging to cheat. The publisher also reports rumors of institutional blowups and rising neocloud debt risks.

James Bulltard — 10/19/26 Recap

James Bulltard shares a personal trading diary, noting that the SPY was rejected by its 50-day moving average. The author details options trades in GFL, CF, BHF, AMZN, and CRWV, and highlights unusual options activity in AXP, GEO, ARXS, RTO, and GNRC.

SemiAnalysis — Datacenters 2027: The Year of Acceleration, +50GW in a Single Year

SemiAnalysis forecasts that global datacenter capacity additions will accelerate to 50GW in 2027, supported by slightly under $1 trillion in year-to-date signed leases. However, the publisher warns of a potential 10GW datacenter oversupply by late 2028 due to silicon shortages.

TMT Breakout — TMTB EOD Wrap

TMT Breakout reports that tech shares bounced back with QQQ up 1.2%, led by memory and storage. The publisher highlights Goldman Sachs' upgrade of CoreWeave, Blackstone's potential $60 billion financing for Anthropic, and Morgan Stanley's Top Pick designation for Amazon.

TMT Breakout — TMTB Morning Wrap

TMT Breakout provides a morning roundup of tech sector news, highlighting Goldman Sachs' upgrade of CoreWeave, Bernstein's upgrade of Datadog, and JPMorgan's upgrade of Intel. The publisher also notes design changes to Google's TPU v9 that could delay shipments into 2028.

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.

Common questions

What did paid research publishers publish on 2026-10-19?

10 pieces from 7 of the publishers tracked by Quant Data: Capital Wars, Cassandra Unchained, FundaAI, Irrational Analysis, James Bulltard, SemiAnalysis, TMT Breakout. Ten research pieces from seven publishers: S&P 500 narrowness mirrors 2000 top, 2027 datacenter buildout accelerates to 50GW, and CoreWeave credit risks rise.

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.

Sources: publicly available Substack newsletters that Quant Data accesses through paid subscriptions. Statements and figures are attributed to their publishers and reproduced as stated; Quant Data has not verified them and expresses no view on them. Educational only: not investment advice, not a recommendation, not a forecast.
