S&P 500 had its worst day since 2025’s ‘Liberation Day’ tariffs
Japan’s benchmark Nikkei stock index fell more than 6% after trading opened Friday, Nov. 6, in Tokyo, a decline that followed a widespread selloff of artificial-intelligence-related stocks on Wall Street.
The figure captured the session’s opening moments, not a close. The Associated Press reported that the Nikkei “tumbled more than 6% after trading opened Friday,” placing the drop at the start of the Tokyo session.
The selling that Tokyo followed unfolded the day before in the United States. The S&P 500 fell 4.4% on Thursday, which AP described as the index’s worst day since April 2025.
AP’s comparison reached back to the tariff announcement of April 2025, when U.S. President Donald Trump’s “Liberation Day” tariffs shook markets worldwide.
The report characterized the Wall Street selling as widespread and centered on issues related to artificial intelligence, and it placed the Nikkei’s decline directly after that selloff.
The brief gave no closing figures for either market and no additional detail on individual stocks.
As the report sequenced it, artificial-intelligence-related stocks sold off widely on Wall Street, the S&P 500 logged its worst day since April 2025, and Japan’s benchmark index opened Friday down more than 6%.
