Markets rallied after news broke that the U.S. and China reached a 90-day trade agreement, reversing many of the April tariffs. Tariffs on Chinese goods dropped to 30%, and China’s on U.S. goods fell to 10%. President Trump’s tweet about 80% tariffs sparked concern, but Sunday night futures surged, erasing losses. This shift reduces uncertainty and mirrors 2018–2019 patterns. Long-term investors should stay focused, as history shows markets rebound once clarity returns.
