Dow, S&P 500, Nasdaq Rally as Supreme Court Strikes Down Trump Tariffs

U.S. stocks rose on February 20, 2026, posting weekly gains after the Supreme Court ruled President Trump lacked authority to impose sweeping tariffs under emergency powers. The S&P 500 added 0.7%, the Dow gained 0.5%, and the Nasdaq climbed 0.9%. President Trump announced a 10% global tariff to replace the struck-down duties. The rally occurred despite data showing Q4 GDP growth slowed to 1.4%, below expectations, and the core PCE index rose more than forecast in December.
