Semiconductor Surge Drives Selective Rally as Defensive and Consumer Stocks Retreat — September 18, 2026

Market Overview

Tokyo equities traded with a sharply bifurcated tone on September 18, 2026, as a powerful rally in semiconductor and chip-related names lifted the Nonferrous Metals and Electrical Equipment sectors, while broad-based selling in food, real estate, utilities, and consumer-facing stocks weighed on overall market sentiment. The session underscored investors’ continued appetite for technology exposure even as defensive and rate-sensitive sectors came under pressure. With no major macro catalysts immediately apparent, the day’s narrative was largely driven by sector rotation and position adjustments.

Top Gainers

The standout performer of the session was Lasertec Corp (6920), surging +8.70% to lead the Nikkei 225 — a move that reinforced the company’s status as a bellwether for semiconductor equipment demand. The rally was broad across the chip supply chain, with Advantest Corp (6857) climbing +5.99%, IBIDEN Co Ltd (4062) adding +5.85%, and SUMCO Corporation (3436) rising +5.60%. Tokyo Electron (8035) and SCREEN Holdings (7735) posted gains of +4.20% and +3.94% respectively, while passive components maker Murata Manufacturing (6981) advanced +4.47% and Taiyo Yuden (6976) gained +4.17%. Renesas Electronics (6723) also participated in the move, rising +4.45%. Notably, Mitsui Kinzoku Co Ltd (5706) was the second-largest gainer at +7.35%, reflecting strength in nonferrous metals that complemented the technology theme.

Top Decliners

Selling pressure was concentrated in food producers, consumer staples, and select industrial names. Nisshin Seifun Group (2002) led declines with a drop of -4.15%, followed closely by Sharp Corp (6753) at -4.08%. Marine food producer Nissui Corporation (1332) fell -3.49%, with NH Foods (2282) and Sapporo Breweries (2501) also retreating by -3.40% and -3.20% respectively. Specialty chemicals firm Kuraray Co (3405) shed -3.11%, while internet platform operator LY Corporation (4689) declined -3.07%. Defensive infrastructure names were not spared, with East Japan Railway (9020) losing -2.84% and home furnishings retailer Nitori Holdings (9843) slipping -2.82%.

Sector Snapshot

Nonferrous Metals was by far the day’s best-performing sector, averaging a gain of +3.52%, buoyed by metals critical to semiconductor and EV supply chains. Electrical Equipment followed with a solid +1.35% average gain, reflecting the chip-equipment and electronic components rally. Securities and Pharmaceuticals were broadly flat, each edging up marginally.

On the downside, the breadth of selling was striking. Fisheries was the worst-performing sector at -3.49%, consistent with weakness in individual names like Nissui. Food averaged -1.87%, Gas fell -2.16%, and Textiles lost -2.29%. Cyclically sensitive sectors including Real Estate (-1.91%), Electricity (-1.81%), and Shipping (-1.74%) also underperformed, suggesting investors rotated capital decisively out of yield-sensitive and domestic demand-oriented names and into globally exposed technology plays.
