Tokyo Stocks: Nikkei 225 and TOPIX Daily — 2026-10-12
The Nikkei 225 experienced a volatile week, surging past the psychological 70,000 level on Monday before retreating due to profit-taking and inflation concerns. Foreign investors displayed mixed positioning, with record selling in futures contrasting against net buying in cash equities, while the launch of a major TOPIX index revamp added structural uncertainty to the broader market.

Nikkei Surges Past 70,000 on AI Chip Rally Before Retreating
On Monday, October 5, the Nikkei 225 jumped 2.40% to close at 69,946.86, its highest level since July, briefly topping 70,000 intraday for the first time in three months. The rally was driven by semiconductor giants Tokyo Electron, Advantest, and SoftBank Group, fueled by weaker US jobs data that tempered expectations for further Federal Reserve rate hikes. This momentum, however, proved short-lived as investors began locking in gains later in the week.
SoftBank Slide and Inflation Data Drag Index Down to ~68,300
By mid-week, the tone shifted sharply as Hot Tokyo inflation data weighed on sentiment, particularly impacting SoftBank Group and other high-multiple tech stocks. On October 8, the index fell 1.4% to 69,042.11 amid weakness in machinery and financial sectors following the Bank of Japan's economic assessment. By Friday, October 10, the Nikkei closed at approximately 68,994, marking a weekly loss as doubts about the sustainability of the AI rally and global bond market stress took hold.
Foreign Investors Sell Record Amount of Futures While Buying Cash Equities
A notable divergence in foreign investor behavior emerged during the week ending October 9. Overseas investors dumped Japanese stock futures at a record pace while simultaneously buying cash equities, reflecting uncertainty over whether the recent rally could be sustained. This hedging activity suggests that while institutional funds remain bullish on individual corporate fundamentals, they are increasingly cautious about macro-level volatility and potential interest rate adjustments by the Bank of Japan.
TOPIX Revamp Announced: 683 Companies Face Removal
Japan Exchange Group (JPX) announced a major overhaul of the TOPIX index on Wednesday, October 7, marking a significant milestone in corporate governance reforms. Under tougher inclusion rules, 683 companies are earmarked for removal from the index, which could trigger significant passive fund outflows from these specific stocks. This move aims to enhance the index's quality and reflects the ongoing pressure on Japanese firms to improve capital efficiency and governance standards.
Local view
Local media highlighted the strength of specific industrial names amidst the broader volatility. The Nikkei newspaper reported that Komatsu hit an all-time high on October 5 after foreign analysts upgraded their investment stance to "buy," signaling continued confidence in Japanese machinery exports despite yen fluctuations. Meanwhile, Newsweek Japan noted that the Nikkei extended gains on October 6 to close at 70,683.98, supported by falling oil prices and earnings expectations, even as some sectors faced negative reactions to previous day's surge. Local commentators are also focusing heavily on the "TOPIX revamp," with discussions centering on how the removal of hundreds of stocks will reshape portfolio allocations for retail and institutional investors alike.
