On Tuesday, May 12, 2026, Japan’s Nikkei 225 share average closed higher as investors rotated back into technology and AI-related stocks following a volatile morning session. Despite the global “risk-off” sentiment fueled by US-Iran tensions, the benchmark index rose 324.69 points (0.52%) to settle at 62,742.57.
AI and Tech: The Market’s “Buying the Dip” Target
Investors largely shrugged off early weakness in Asian markets, focusing instead on companies positioned to profit from the global surge in artificial intelligence.
-
Connectivity Leaders: Fiber optic cable makers led the gains. Furukawa Electric soared 16% after announcing a stock split, while its peer Fujikura jumped 11.6%.
-
Chip Resiliency: While chip-making equipment stocks started in the red due to regional volatility, Tokyo Electron recovered to end 0.14% higher. Advantest, a key Nvidia supplier, also narrowed its losses to close just 0.26% lower.
-
SoftBank Surge: Technology investor SoftBank Group rose 4.25% as anticipation builds for its quarterly earnings report due tomorrow.
-
Smartphone Components: Ibiden jumped 5.7% after upgrading its annual sales and profit forecasts, citing strong tech demand.
Global and Domestic Headwinds
While AI stocks provided the boost, the broader market remains capped by significant macroeconomic concerns:
-
Geopolitical Friction: Markets remain on edge after U.S. President Donald Trump described the ceasefire with Iran as being on “massive life support.”
-
BoJ Rate Hike Signals: The Bank of Japan’s “Summary of Opinions” from April hinted at potential interest rate hikes as early as June, particularly if rising oil prices (currently near $105/barrel) continue to drive inflation.
-
The “Uniqlo” Drag: Retail giant Fast Retailing fell 3.77%, serving as the single biggest weight on the Nikkei today and reflecting broader concerns about consumer spending under inflationary pressure.
