single-day change vs previous close

Part of a longer stretch

The same argument, shallower in Tokyo

midway through · 2026-06-25 → 2026-07-29, -15.11% over the whole period

What happened that day?

  • The Nikkei 225 fell 4.03% on the day
  • Days earlier chip shares had collapsed in Korea and the KOSPI had fallen 669 points in a session. The aftershock was still running
  • What marks this period in Japan is how large the weight of chipmaking equipment and materials firms had become. Their results move with world capital spending
  • Capital spending falls before the economy does and rises before it too. That makes these shares unusually sensitive to the outlook
  • No actual decline in orders had been confirmed. What was in the price was the calculation that orders would fall
  • The correction ended in late July as US technology results came in
