Historic Surge on Tokyo Exchange

Tokyo's stock market experienced a dramatic surge on July 7, with the Nikkei 225 index achieving historic milestones. The benchmark index closed at 62,833.84, marking an unprecedented gain of 3,320.72 points. This significant advance saw the Nikkei 225 breach the psychologically important 63,000 level for the very first time. The broader TOPIX index also extended its gains, surpassing its previous record high. By midday, the TOPIX had climbed 25.16 points, or 0.85%, to reach 2,991.73, edging past its prior peak of 2,977.55 set on July 24. The JPX Prime 150 index similarly continued its upward trajectory through the morning session.

Drivers of the Rally: AI and Geopolitical Easing

The market's robust performance was fueled by a confluence of factors, primarily strong expectations for growth in the artificial intelligence sector and a perceived reduction in geopolitical tensions in the Middle East. These elements combined to create a powerful tailwind for Japanese equities. Investor optimism was further bolstered by positive performance in U.S. markets the preceding day. The Dow Jones Industrial Average and other major U.S. indices closed higher, a sentiment that rippled across to Tokyo. The substantial rise of Apple in the U.S. market, driven by news of increased domestic production investments, significantly lifted investor confidence and contributed to the buying wave in Japanese stocks.

Market Dynamics and Key Movers

The morning session on July 7 saw the Nikkei 225 open with a substantial lead, continuing its upward trend. While initial trading exhibited some caution due to concerns about short-term overheating and the potential impact of U.S. semiconductor policy, a consistent flow of buying in index futures, believed to be from overseas short-term players, propelled the market higher. By mid-morning, the index was advancing significantly. Stocks with high influence on the Nikkei 225, such as SoftBank Group (SBG) and Fast Retailing, experienced strong buying interest. TDK, associated with Apple's supply chain, also saw its share price climb. Conversely, some companies like Fujikura, Honda, and Kao registered declines.

Semiconductor Sector Faces Uncertainty

Despite the overall market buoyancy, the semiconductor sector presented a mixed picture. News emerged regarding potential U.S. tariff policies on semiconductors. President Donald Trump reportedly indicated plans to impose "approximately 100% tariffs on all semiconductors imported into the United States." This prospect led to a decline in some high-priced semiconductor-related stocks, including Tokyo Electron, as investors considered the potential impact on investment by semiconductor manufacturers. However, the broader market's positive sentiment, driven by U.S. market strength and anticipation of further Japanese stock appreciation, appeared to outweigh these sector-specific concerns for many investors. Overseas investors were also observed to be buying Japanese stocks, seemingly focusing on comparative advantages related to U.S. trade policies.

Trading Activity and Market Breadth

Trading volume on the TOPIX Prime market was robust, reaching an estimated 2.0611 trillion yen by midday. The total number of shares traded stood at approximately 1.13781 billion. The breadth of the market was overwhelmingly positive, with 1,163 stocks advancing, representing about 70% of all listed companies on the Prime market. Only 405 stocks declined, and 54 remained unchanged. The yen's movement against the dollar showed resilience, trading with a downward bias but showing some correlation with oil prices. The foreign exchange market's stability contributed to the overall positive trading environment.
