# US News & Sentiment Skill (Alpha Vantage) ## When to use Trigger this skill on any US-listed ticker when the analysis needs: - **Sentiment confluence** with technicals (per AGENTS.md Section 4: a high-conviction call requires technicals + at least one of {sentiment, fundamentals, flow}). - **Catalyst detection**: M&A, earnings reactions, guidance changes, regulatory actions, analyst rating shifts. - **Pre-trade event-window check** for non-earnings catalysts (FDA decisions, conference talks, product launches). - **Sanity check on a price move**: is the move news-driven or noise? Do NOT use this skill for: - KLSE tickers — use `klse-news` instead. - Crypto — coverage on AV is thin and unreliable; use a crypto-native source when wired. - Earnings-release scheduling on US names — AV's news is reactive; for the actual earnings calendar use FMP or earnings-specific endpoints (not yet wired). ## Why this exists Massive MCP gives prices and indicators, not news/sentiment. Per AGENTS.md Section 4, technicals alone are not enough — confluence requires sentiment OR fundamentals OR flow. Without a news source, every US recommendation would be flying half-blind on confluence. Alpha Vantage's NEWS_SENTIMENT is the fastest, cheapest way to close that gap; it ships per-article ticker-level sentiment scores that AV pre-computes, plus topic tags, plus relevance scores per ticker. ## Setup — one-time 1.
