What Sparked the Sudden Market Moves?

At 7:00 AM UTC on February 21, headlines hit: Trump’s long-anticipated tariff cuts on Chinese imports were finalized.

Could This Be a Head Fake Before a Deeper Correction?

Possibly. Remember March 2022? Tariff relief sparked a 3-day rally before the Fed rained on the parade. This time, watch bond yields.
