Canadian Stock Market Today: TSX Closes Below 30,000 as Nvidia Rally Fades and Miners Slump (November 20, 2025)
Canada’s main stock index reversed hard on Thursday, November 20, 2025, as an early surge powered by Nvidia’s blockbuster results gave way to a broad sell‑off in materials and parts of the tech and energy complex. According to end‑of‑day data, the S&P/TSX Composite Index closed at 29,932.25, down 346 points or about 1.14%, after trading as high as 30,632.84 and as low as 29,917.17 during the session.
