Nikkei 225 — daily market movers
Macro backdrop
The Nikkei 225 ended roughly flat, down about 0.05%, its fifth straight decline. It opened higher on a rebound but reversed in the afternoon after ASML's results soured chip sentiment, compounded by reports that a Chinese memory-chip maker plans high-performance products (stoking competition fears), mixed US big-bank earnings, and caution ahead of that evening's US September CPI. Banks, brokerages and precision instruments led the declines, while petroleum/coal, nonferrous metals and chemicals led gains — a clear rotation out of financials and memory chips into chemicals/materials and defensive value.

Common Themes
The gainers cluster in materials and value. Three chemicals names (Sumitomo Chemical, Mitsui Chemicals, Mitsubishi Chemical) plus nonferrous smelter Mitsui Kinzoku track the sectors that led the tape, while Ajinomoto and Fast Retailing reflect a defensive bid. A few electronics names (Taiyo Yuden, Fujikura, Fuji Electric) rose even as memory chips fell, suggesting selective buying rather than a broad tech rally. No single-company catalyst drove the group — it was sector rotation.

Common Themes
The losers are dominated by financials: regional banks (Shizuoka, Yokohama), Resona, trust bank Sumitomo Mitsui Trust and brokerage Nomura all fell as banking (−2.6%) and securities (−2.5%) were the day's worst TSE sectors, on profit-taking after a strong run and mixed US bank earnings. Memory maker Kioxia and medical-device makers Terumo and Olympus round out a weak precision-instruments group — though Olympus (FDA warning letter) and retailer Aeon (disappointing first-half earnings) fell on their own company-specific news rather than the macro theme.
Overall read
A nearly flat index masked a sharp rotation. Money moved out of crowded financials — the banks and brokerages that had run up on the rate-hike trade — and out of memory chips, into chemicals, nonferrous metals, energy and defensive value names. The biggest single-stock losses, Olympus and Aeon, were idiosyncratic regulatory and earnings stories rather than part of the macro theme.
