All three major Wall Street indexes – Dow, S&P, and Nasdaq, ended Tuesday with biggest one-day drops in three months (since October 10, 2025), likely triggered after US President Donald Trump threatened to hit eight European countries with new tariffs to assert control over Greenland. The S&P 500 lost 143.15 points, Nasdaq lost 561.07 points, and Dow fell 870.74 points.
