Market Signal Solutions

About

Who We Are MarketSignal Solutions is an alternative data provider based in Quebec, Canada, founded by Keven Dube. We build AI-powered financial feature datasets designed for quantitative researchers, algorithmic traders, and systematic portfolio managers.

Our mission is straightforward: deliver production-grade, ML-ready feature matrices that combine real news sentiment with market data — so quants can focus on modeling, not data engineering.

What We Produce 1,442 engineered features per 15-minute batch, 96 observations per day, 24/7 coverage. Built on three fused data layers:

• GDELT Layer (~1,403 cols) — GKG content analysis, geopolitical events, media mentions, 1,256 GCAM sentiment dimensions, entity detection, sector analysis, sentiment velocity, macro themes
• AI Layer (18 cols) — Google Gemini 2.5 Flash sentiment scoring, impact/novelty/controversy scores, narrative classification, binary event flags, AI reasoning
• Price Layer (21 cols) — Multi-source intraday prices from Polygon, Twelve Data, and Yahoo Finance with cross-source consensus metrics

Coverage

• Magnificent 7: NVDA, AAPL, TSLA, AMZN, META, MSFT, GOOG
• Time span: January 2026 onward, updated monthly
• Resolution: 15-minute batches, 96 per day, 24/7

Our Data Pipeline Dedicated infrastructure processing GDELT global news data every 15 minutes:

1. GDELT Ingestion — Three data streams (GKG, Events, Mentions) downloaded and parsed every 15 minutes from the GDELT global feed
2. Content Analysis — 1,256 GCAM dimensions applied to each article batch — emotional, thematic, and linguistic scoring across validated lexicons
3. AI Enrichment — Google Gemini 2.5 Flash (temperature=0, deterministic) analyzes each batch — 18 structured features per ticker including narrative classification and reasoning
4. Price Collection — Multi-source intraday prices from Polygon, Twelve Data, and Yahoo Finance, cross-validated daily post-market
5. Assembly — GDELT + AI + Price layers merged into unified 1,442-column rows per 15-minute batch

Data integrity is non-negotiable. Every dataset passes automated quality audits before publication: column count validation, date continuity, sentiment coverage, and more.

Why Choose MarketSignal Solutions Real Sentiment, Not Synthetic. Every sentiment score traces back to actual financial articles analyzed by AI. We process the full text — not just headlines. This is fundamentally different from LLM-generated synthetic sentiment datasets flooding the market.
