What paid research said today, on the record. What the options market shows, computed nightly.

Quant Data reads 14 paid research publishers every day and records what they published as an attributed ledger: who said what about which ticker, the numbers they put on the record, and what they said would prove them wrong. Next to it, options positioning Quant Data computes itself for 25 individual US stocks and 18 ETFs, dated to the settlement it came from.

It records and measures. It does not recommend a trade.

Seven notes from six publishers: Meta Muse launch, Capital Wars maps a 5-6 year liquidity cycle, and a hedge fund trims its AI-chain shorts

On 2026-09-09 the tracked publishers put out seven pieces from six sources. Capital Wars ran a long interview with Michael Howell on global liquidity cycles. TMT Breakout published two notes: a morning wrap on Meta's new Muse AI agent and an end-of-day roundup of Goldman Sachs and Citi tech-conference recaps spanning dozens of companies. Damnang and SemiAnalysis each ran deep research pieces, on the AI memory-hierarchy standards fight and on-device versus datacenter robot inference. James Bulltard posted a personal trading-milestone update centered on Intel, and Cassandra Unchained posted a hedge-fund position update trimming both its long and short books. Every statement below is attributed to the publisher or sell-side desk that made it, in that source's own numbers; Quant Data did not verify any of it and takes no view.

Standing research

Questions the site measured once and keeps measuring. Each is published with its method and its own numbers, and the results that failed sit in the same tables as the ones that held.

What has actually been measured?

Every event rate is pre-registered with its sample size, and the failed claims are published next to the confirmed ones. The day-type model is scored on held-out ES years. Options outputs state whether they are arithmetic or estimates.

No hold rate has been measured for max pain, gamma flip, or the heavy strikes. They are positioning snapshots, not support, resistance, or targets. The research ledger is a record of what publishers said; their numbers are theirs, not ours.

Common questions

What is Quant Data?

A free content site with a data layer. Each day it reads 14 paid research publishers and records what they published as a dated, attributed ledger: titles, directional statements with the originating voice, the numbers they stated, and the observations they said would prove them wrong. Alongside, it computes options positioning nightly for 43 US stocks and ETFs and publishes 11 standing studies with their methods and failures.

Where does the research content come from?

From paid research publishers accessed through the GeoScope aggregator under a licence that permits redistribution. Quant Data reproduces statements and figures as stated, attributed to the publisher, and does not verify them or take a view on them. Titles and content belong to the publishers.

Is a "bullish" entry a recommendation?

No. It records that a named source expressed a direction on a named ticker on a dated day. The record exists so that statements can later be checked against what prices did. Quant Data does not recommend buying or selling, set targets, or personalise anything.

How often does it update?

The research notes are written each day the publishers publish. Options positioning is rebuilt nightly from end-of-day open interest and every page prints its settlement date; it is never an intraday reading.

What does the newsletter contain, and what does it cost?

The same daily notes that appear on this site, delivered by email in English or Chinese. It is free; you confirm the address first, and unsubscribing deletes it. The full text of every note stays on the site.

Is there still an API?

Yes. The positioning data and the measured models behind these pages are available as a JSON API and an MCP server for people and AI agents: a free key with 10 calls a day, or a $149/month plan. Existing keys and prices are unchanged.

Is this investment advice?

No. Everything here is descriptive: attributed records of what others said, historical measurements, and options open-interest arithmetic. Nothing is a signal, a target, or a recommendation.
