The TOPIX (Tokyo Stock Price Index) finished its penultimate week of 2025 in a position of historical strength, reflecting a broader trend of resilience in Asian equity markets. As global markets transition into 2026, the index has solidified its status as a primary driver of global portfolio alpha, supported by robust corporate earnings and structural governance reforms that have revitalized the Japanese Capital market.

Structural Growth and the Tech Rebound

The defining story of the week was the TOPIX’s ability to maintain its upward trajectory, culminating in a year-over-year appreciation of over 22%. This rally has been significantly fueled by a decisive push into high-growth technology and semiconductor sectors, which benefited from a global recovery in AI-related hardware demand. For sophisticated investors, including those in Israel looking for emerging market diversification, the Japanese market’s evolution from a defensive value play to a growth-oriented Capital market remains a pivotal theme as we enter the first quarter of 2026.

Fiscal Stimulus and Monetary Policy Divergence

A primary catalyst for the week’s sentiment was the Japanese government’s approval of a record ¥122 trillion budget for the new fiscal year, signaling continued fiscal support for domestic infrastructure and technology. Simultaneously, the Bank of Japan (BoJ) has remained a focal point as it navigates the end of its ultra-loose policy. While the Bank of Israel and other central banks have already begun modest easing cycles to support growth, the BoJ’s move toward “normalization” represents a unique monetary policy divergence. This shift is expected to support a stronger Yen in 2026, potentially challenging exporter margins while increasing the attractiveness of domestic-focused assets and banks.

Market Liquidity and Technical Resilience

Despite the thin holiday trading volumes typically seen in late December, the TOPIX showed remarkable technical resilience, bouncing off its 1-month support level to test fresh peaks. The index’s Average Volume (3m) of approximately 2.55 billion reflects a deep and liquid market capable of absorbing the “Great Rotation” from overvalued Western tech giants into Japanese industrials. As inflation in Tokyo shows signs of stabilizing above the 2% target, the financial performance of the broader index is increasingly driven by real wage growth and a revitalized consumer morale.

Looking ahead, the outlook for the TOPIX entering 2026 is one of cautious optimism. Analysts expect a transition from valuation re-rating to earnings-driven appreciation, with a key focus on the BoJ’s January 2026 Outlook Report for signals on the timing of the next rate hike. Key risks to monitor include any sudden geopolitical shocks that could trigger a safe-haven flight and the impact of new global trade tariffs on Japanese exports. However, given the current support levels near 3,411 and the structural reforms underway, the index is well-positioned to challenge the 3,500 psychological barrier in the coming months.
