Nucor is trading 5.42% up now at $256.82 after failed U.S.-Canada trade negotiations left 50% steel tariffs in place on August 24, 2026.

  • Investors had feared tariffs would fall to 25%, increasing Canadian competition and pressuring U.S. steel prices.
  • The reversal triggered a rebound across U.S. steel shares after last week’s tariff-related selloff.
