🇯🇵 JAPAN’S STOCK MARKET CRASH EXPLAINED:
The Nikkei is now down over -14% from its June record, after falling another -4% today.|
Two forces are driving the selloff:
1. AI fatigue and a valuation reset
The Nikkei had surged 37% in 2026, largely powered by AI and semiconductor companies.
Chip-related stocks grew to roughly 25% of the entire index, meaning Japan became heavily dependent on a small group of winners.
Now, investors are questioning whether record AI spending can generate enough profit to justify those valuations.
That reversal is hitting the former market leaders hardest:
SoftBank: −7%
Advantest: −6%
Kioxia: −9.5%
Tokyo Electron: −5%
2. China is becoming more self-sufficient in chips
China has reportedly started producing its own DUV chipmaking machines.
That matters because companies such as ASML and Japanese chip-equipment makers rely heavily on selling these machines to China.
ASML fell 8.5% as investors priced in the risk that China may need fewer foreign suppliers over time.(Coin Bureau)
