The Japanese market took a breather on Friday, with the Nikkei 225 pulling back from its historic peak. After a blistering rally that saw the index cross the psychological 63,000 mark for the first time on Thursday, profit-taking and renewed global anxieties triggered a marginal retreat.
SoftBank and Arm: The Tech Drag
The biggest weight on the Nikkei was technology giant SoftBank Group, which tumbled 4.56%. The sell-off followed a sharp decline in its subsidiary, Arm Holdings, on U.S. exchanges.
-
Smartphone Slump: Investors are reacting to signs of prolonged weakness in the global smartphone market.
-
AI Supply Bottlenecks: Despite the AI boom, concerns over the supply chain for specialized AI chips have caused a reassessment of near-term growth projections for Arm.
Geopolitical Heat and “Safe Haven” Shifts
Market sentiment was further dampened by a sudden escalation in the Middle East. Renewed hostilities between the U.S. and Iran have cast doubt on a month-long ceasefire, leading to:
-
Rising Crude Prices: The threat to shipping and regional stability pushed oil prices higher, a negative for resource-poor Japan.
-
Auto Sector Pressure: Toyota Motor fell 2.18% after forecasting a 20% profit decline for the current fiscal year. The automaker cited rising costs and supply chain uncertainties linked to the Middle East conflict.
Sector Performance Highlights
Despite the broader index dip, the week remained overwhelmingly positive, with the Nikkei gaining 5.4% over the holiday-shortened period.
| Company / Sector | Movement | Catalyst |
| Sumco | +18% | Top gainer; massive demand for silicon wafers. |
| Advantest | +0.57% | Recovered early losses to end in the green. |
| Sony Group | -0.51% | Forecasted a 6% drop in gaming sales due to slowing hardware demand. |
| Banking (MUFG/Mizuho) | -2% avg | Dragged down by broader cautious sentiment. |
The “Normalization” View
Strategists suggest that today’s retreat is a “marginal” correction rather than a trend reversal. After a 5.6% jump on Thursday, a slight cooling off is considered healthy. However, the divergence between the Topix (+12% YTD) and heavyweights like Sony (-23% YTD) suggests that the market is becoming increasingly selective, rewarding industrial strength while punishing tech and consumer electronics firms facing hardware headwinds.
