Tech and Semis Surge as SoftBank Leads Broad Rally in Japanese Equities — September 07, 2026

Market Overview

Japanese equities staged a powerful rally on Monday, with technology and semiconductor-related names driving broad-based gains across the Nikkei 225. The session was defined by outsized moves in high-beta tech stocks, suggesting renewed investor appetite for risk in the Tokyo market. While the advance was not universal — defensive and domestically oriented sectors came under pressure — the scale of gains among market leaders pointed to a distinctly bullish tone.

Top Gainers

The session’s standout performer was SoftBank Group Corp (9984), which surged +11.22% to top the Nikkei 225 leaderboard by a wide margin. The conglomerate’s outsized move likely reflects renewed enthusiasm around its artificial intelligence and technology investment portfolio, which has made the stock highly sensitive to shifts in global risk sentiment.

Semiconductor and advanced materials names followed closely behind, underscoring a thematic bid across the chip supply chain:

• Ibiden Co Ltd (4062): +8.42% — the IC substrate specialist attracted strong buying interest.
• ROHM Co Ltd (6963): +7.77% — the chipmaker extended recent momentum.
• Lasertec Corp (6920): +7.26% — the EUV mask inspection equipment maker rebounded sharply.
• Resonac Holdings (4004): +6.76% — the advanced materials group benefited from semiconductor sector tailwinds.
• Panasonic Holdings (6752): +6.20% and Murata Manufacturing (6981): +5.97% added to the electronics sector’s strong showing.
• Disco Corporation (6146): +4.94% and Tokyo Electron (8035): +4.73% rounded out a broadly constructive day for chipmaking equipment.

Top Decliners

The session’s losers were concentrated in IT services, consulting, and healthcare — sectors with more defensive or domestic-growth profiles that appeared to face rotation selling as capital moved into hardware and tech infrastructure plays.

• SHIFT Inc (3697): -5.91% led declines among services names.
• Konica Minolta (4902): -5.65% and Nomura Research Institute (4307): -5.61% also fell sharply.
• BayCurrent Inc (6532): -5.38% and Trend Micro (4704): -5.38% came under equal pressure.
• NEC Corp (6701): -4.52% was a notable decliner given its scale, while Chugai Pharmaceutical (4519): -3.40% extended weakness across the broader pharmaceuticals space.

Sector Snapshot

Shipping (+3.12%) topped the sector leaderboard, followed by Shipbuilding (+2.24%) and Telecommunications (+2.02%), suggesting a wide appetite for Japan’s industrial and infrastructure-linked names. Ceramics (+1.97%) and Electrical Equipment (+1.89%) reflected the semiconductor materials and components bid, consistent with the individual stock moves seen at the top of the market.

On the negative side, the Services sector (-2.85%) was the worst performer by a considerable margin — a trend consistent with the sharp declines seen in IT consulting and software stocks. Pharmaceuticals (-1.40%), Retail (-1.16%), and Real Estate (-1.08%) also finished in the red, as investors appeared to favour cyclical and technology exposure over domestic consumption and income-sensitive sectors. Banks (-0.99%) slipped modestly, adding a cautious note to an otherwise risk-on session.
