Enphase, MYR Group Surge as Supreme Court Strikes Down Tariffs

Shares of manufacturers including Enphase Energy and MYR Group surged on Feb. 20, 2026, after the U.S. Supreme Court struck down Trump-era tariffs. In a 6-3 decision, the court ruled the administration improperly used the International Emergency Economic Powers Act of 1977 to justify the duties, a move expected to lower costs for imported materials and equipment. Economists suggest the ruling will alleviate budget pressures and ease inflation, potentially accelerating Federal Reserve rate cuts. MYR Group (MYR) hit a new 52-week high of $281.09, up 24% year-to-date. The decision provides significant relief for small and medium-sized businesses burdened by previous import costs.
