Dual-Tier Stock Research System

A 3-workflow financial intelligence system that monitors news, tracks entity frequency, and autonomously generates two tiers of research — daily quick briefs and weekly due diligence reports.

What It Does

This system runs without manual input:

  1. Financial Analysis V2 (27 nodes) — the brain. Monitors 4 RSS feeds, sends articles to Minimax LLM for structured analysis (sector, sentiment, tickers, impact score), filters for high-signal content, and tracks company mention frequency using n8n DataTable with upsert logic.

  2. Daily Analysis (14 nodes) — triggered when any ticker crosses 3+ daily mentions. Pulls the latest 20 news articles from Alpha Vantage’s NEWS_SENTIMENT API, cleans the data, and sends it to Minimax to generate a 500–800 word brief structured as [WHAT] → [WHY] → [ACTION]. Delivered to Telegram.

  3. Weekly Analysis (9 nodes) — triggered when any ticker crosses 20+ weekly mentions. Makes parallel Alpha Vantage calls for company fundamentals (OVERVIEW: PE ratio, profit margin, market cap, 52-week range, revenue, EPS) and news sentiment (50 articles). Merges both datasets and sends to Minimax for a 1,500–2,500 word due diligence report. Delivered to Telegram.

Hey, this looks real interresting. Video mentions workflow files available here in the community, but can’t seem to find them. Would love to test and provide feedback. Best, Jan
