Ryan Detrick Posts 85 Years of S&P 500 Shock Data as Trump-Era Volatility Intensifies

Summary
More than three dozen market shocks since 1940 show the S&P 500’s post-shock performance in data Ryan Detrick published after Trump’s latest run of geopolitical crises.
The dataset was framed against sharp Trump-era swings, including a 34% S&P 500 plunge in 33 days during the COVID crash and a drop of more than 10% in two sessions during the April 2025 tariff selloff.
Detrick’s post followed a second term marked by sweeping tariffs, a June 2025 U.S. strike on Iranian nuclear facilities, the January 2026 removal of Venezuela’s Nicolas Maduro and military operations against Iran starting in February 2026.
The broader backdrop is a market that has still climbed strongly under Trump: since his second inauguration, the Dow, S&P 500 and Nasdaq were up 23%, 28% and 32% through Aug. 24.
