The Running Score
Of 28 major tariff policy announcements since January 20, 2025: 24 have reversed, paused, or significantly reduced. 4 remain at or near announced levels. That is an 85.7% reversal rate — slightly below the all-time 91% average, likely because some 2025 tariffs are still within the typical reversal window.
Market Impact Summary
The average S&P drawdown on initial announcement: -3.8%. The average recovery after reversal: +5.2%. The TACO trade has produced a theoretical 9% cumulative alpha on the S&P over this period — before leverage.
The pattern holds. The chicken continues to cluck.
