The System
ACX Signal is a structured intelligence system — not a newsletter, not a forecast, not an opinion.

66 signals across 7 categories, processed through a three-layer analytical framework, and held to a mark-to-market accountability standard no other China equity research product applies.

01 — Extraction

Structured Signal Extraction

66 signals spanning 7 categories — regulatory filings, executive movements, supply chain shifts, macro policy, and more — sourced from Mandarin-language primaries that English-language coverage does not reach.

02 — Intelligence

Three-Layer Intelligence

Layer 1 extracts facts. Layer 2 synthesizes cross-signal patterns into institutional-quality interpretation. Layer 3 builds forward scenarios with explicit confidence scoring. Raw data becomes actionable intelligence.

03 — Accountability

Mark-to-Market Accountability

Every signal published carries a confidence score and an expiration. It is either proven by subsequent data or rescored with full transparency. No opinion survives without evidence. This is what separates ACX Signal from everything else.

Credibility Engine
Proven or Rescored — How We Hold Ourselves Accountable

Every signal we publish has a shelf life. It is either proven by subsequent data, or rescored with full transparency. This is not a policy — it is a mechanism built into the system.

Step 01
Signal Published
Each Weekly Brief publishes signals with an explicit confidence score and a time horizon. The clock starts.
Step 02
Weekly Tracking
The Signal Scorecard tracks every published signal against incoming data — regulatory actions, price movements, corporate disclosures, macro shifts.
Step 03
Proven or Rescored
Signals validated by subsequent evidence are marked proven. Signals that deviate or fail to materialize are rescored — with the reasoning documented and published.
Step 04
Quarterly Credibility Review
Hit rates, miss patterns, and systematic biases are published quarterly. Methodology adjustments are documented. The track record is public.

Based in the Netherlands for over seven years, he built ACX Signal to capture the alpha embedded in the structural information asymmetry around U.S.-listed China equities — where critical signals remain locked in Mandarin-only sources and SEC disclosure lags up to 90 days.
