Market Overview
Japanese stocks dropped sharply on Tuesday, October 13, 2026, as the market reopened after a three-day holiday. Investors came back to a wave of selling, especially in technology, artificial intelligence, and semiconductor companies. The Nikkei 225 Index closed at 67,777.52, down 1,253.40 points about 1.82%. The TOPIX Index also moved lower, finishing near 4,012.30.

Session Highlights
Volatile Trading, Big Morning Loss
The Nikkei started the day with a big gap lower at 68,564.85, reflecting worries that built up over the holiday. In the first 90 minutes, heavy selling—mainly in stocks like SoftBank Group, Tokyo Electron, and Advantest pushed the index to a low of 67,058.56 at 10:50 in the morning. By afternoon, some buyers stepped in, helping the Nikkei recover 719 points. The index ended the day just above 67,700.
Main Reasons Behind the Drop
Regional Tech Sell-Off
Large sell-offs hit tech companies in Asia, with South Korea’s Kospi dropping by more than 5%. This sparked losses in Tokyo’s tech stocks, which make up a significant part of the Nikkei.
Producer Price Inflation Slows
Fresh economic data showed Japan’s Producer Price Index (PPI) rose 6.8% year-over-year in September, below expectations. This made investors worry that manufacturers might have weaker pricing power, hurting future profits.
Yen and Oil Prices
The Yen traded at 158.26 per dollar, which usually helps exporters. But rising oil prices Brent crude above $105 a barrel increased concerns about higher costs for Japanese companies.
Stocks That Moved the Most
Biggest Losers
- SoftBank Group: Dropped up to 6.12% as AI and tech stocks faced heavy selling.
- Tokyo Electron: Fell 3.92% on concerns over fewer orders for chip equipment.
- Advantest: Lost 4.30%, hit by worries about spending on hardware.
- Lasertec: Down 5.15% amid global chip sector weakness.
- Kioxia: Fell 3.80% following regional memory chip price concerns.
Top Gainers

- Eisai Co: Gained 1.12% as investors favored healthcare for safety.
Technical Overview
The Nikkei bounced back from its intraday low and stayed above key support levels around 67,000. It also remains above its 200-day moving average (66,290), which signals a longer-term bullish trend. To turn positive again, it needs to climb above short-term resistance between 68,600 and 69,030.
Cross-Asset Trends
The Yen’s weaker value continues to support Japanese exporters. Companies like Toyota and Sony are seeing some benefit, having expected a much stronger Yen in their profit forecasts. Oil price spikes present new risks, though.

Looking Ahead: October Outlook
What to Watch
- Quarterly Earnings: Corporate reports will show if weaker Yen offsets rising costs.
- Bank of Japan Policy: Expectations for an interest rate hike are low for October, maybe December instead.
- Global Tech Results: Major U.S. tech company reports will help decide if semiconductor supply chains stabilize.
Market Scenarios
- Recovery: If the Nikkei moves above 68,600, focus on tech, defense, and auto exporters.
- Sideways: If the Nikkei stays between 67,000 and 68,500, energy and bank stocks make sense.
- Bearish: If it closes below 67,000, rotate to safe sectors like utilities and healthcare.
