About

TariffScope analyzes how US tariff announcements affect stock market sectors using a novel Tariff Vulnerability Score (TVS).

Built on 3 live data sources: Yahoo Finance (11 sector ETFs, 2030 trading days), FRED Federal Reserve data (import price index, trade balance), and SEC EDGAR (10-K filing analysis across 1,600+ companies).

Key finding: Utilities is the most tariff-vulnerable sector (TVS: 73.8/100) — not Technology as conventional wisdom suggests. Health Care is the safest haven (TVS: 15.6/100).

Methodology: Formal event study across 24 major tariff events (2018–2025), Cumulative Abnormal Returns (CARs) per sector, volatility spike analysis, and SEC filing sentiment scoring.
