Where a tariff hurts most

-3.56%

single-day change vs previous close

What happened that day?

  • On 10 October 2025 the Nasdaq fell 3.56%, more than the S&P 500 that day
  • The trigger was the US president's announcement of an extra hundred percent tariff on Chinese goods
  • The Nasdaq fell harder because of what it holds. Phones, computers and chips are built in China and sold to China
  • Tariffs raise costs while retaliation cuts revenue. The squeeze comes from both sides
  • China's tools in return, such as controls on rare mineral exports, point straight at chipmakers
  • Peak to trough it was 4.19% and the index recovered quickly
