Nothing on TAPE 33 is fabricated. Every claim in the synthesis is grounded in one of these ten streams, cited inline, clickable to the underlying filing or article. This page is the authoritative provenance reference. Update cadences and licenses are accurate as of 2026-06-05.
10-K, 10-Q, 8-K item codes, Form 3/4/5 insider trades, Form 13F institutional holdings, Form F-6 ADR deposit ratios, XBRL company facts (shares outstanding + fundamentals)
Real-time IEX quotes (primary), 365d candles, dividends, splits, daily fundamentals (P/E, P/B, EV, PEG, dividend yield), corporate actions
News headlines with provider-tagged sentiment (bullish/bearish/neutral), FDA AdComm + PDUFA calendar, earnings calendar with EPS estimates + actuals, insider sentiment time series
Congressional trade disclosures (representative, ticker, transaction date, disclosure date, amount range, transaction type), float fallback when Yahoo misses
Daily short volume / ADV ratio (proxy), biweekly settled shares short, consolidated settled SI with days-to-cover, settlement dates
Per-company trial readouts, phase, primary completion date, conditions, brief titles, NCT IDs
ETF top holdings, sector weights, AUM, expense ratio, trailing returns, fund profile; float shares fallback when FMP cap is hit
Time-stamped PR items keyed by ticker (when extractable from the wire), used to detect material events ahead of 8-K acceptance
Earnings call transcript text used as RAG context for the synthesis when the issuer didn't furnish a transcript exhibit to their 8-K
Vector embeddings of filing chunks for RAG retrieval; AI synthesis with mandatory source citation (no synthesis claim is rendered without a citable chunk grounding it)
The synthesis layer runs on a retrieval-augmented architecture (RAG): every AI-generated sentence is conditioned on chunks pulled from filings, transcripts, and articles via OpenAI embeddings + DuckDB vector search. The model is instructed to decline a claim it cannot ground.
When the synthesis says “the company guided revenue down 12%” — there is a clickable link to the specific filing and the specific paragraph that supports it. When the synthesis cannot find such a paragraph, the synthesis stays silent. This is the doctrine.
