Reading Congress stock-trade disclosures with Claude: three columns that change the answer
EquiblesAI · reddit · 2026-11-09
The author walks through using Claude with a market-data connector to analyze congressional trading disclosures, and the three prompt-level fixes that change the conclusions:
- Amounts are ranges: filings only give "$1,001-$5,000"-style ranges, so rankings are midpoint estimates. A Nov 9 run shows Costco led net selling ($558K, two members), top buys $75K each of Datadog and Estée Lauder, and Pete Sessions appearing in all five top sell rows — the "trend" is one portfolio.
- Owner and instrument: all 25 of Pelosi's trades over 12 months (18 buys, 7 sales) are in her husband's name, 9 are options; the PDF often says more than structured fields (e.g., 10,000 Bloom Energy shares plus 100 calls at a $100 strike).
- Filing lag: Bloom trades made July 24/28 were filed August 21. Closes: $184.89/$166.84 on trade dates, $201.45 on filing date, $173.24 Friday — copiers are down 14%.
He shares a reusable prompt template and notes Claude's value is auto-selecting tools, aligning dates, and doing the math in one message. The connector is the author's own product, Equibles.
