BlockBeats News, April 24th. Upon Trump's return to the White House, his impact on the market reached an unprecedented level. Data from Fundstrat shows that since January 2025, the five largest one-day gains and the five largest one-day losses in the US stock market have all been directly driven by his policies, marking the first time in nearly 40 years that a single president has "swept" market extreme volatility.
Structurally, the gains mainly stemmed from technical rebounds after policy shocks: if the five strongest gain days are excluded, the S&P 500 has changed from a 18.5% gain to a 2.7% loss since his inauguration. The losses were highly concentrated on tariff policy impacts.
Analysis points out that Trump's frequent policy stance adjustments (escalation—relaxation—flip-flop), combined with real-time signals released on social media, have led traders to shift towards "anticipating the president's intentions" for trading, significantly undermining the traditional macro framework.
