NextFin news, On October 29, 2025, Japan’s Nikkei 225 index approached record highs, buoyed by renewed investor confidence primarily emanating from cyclical and value sectors like non-ferrous metals and energy. The Nikkei closed near ¥45,755, marking multiple consecutive record sessions. This rally has been underpinned by rising commodity prices, notably copper and oil, lifting stocks such as Sumitomo Metal Mining by over 11%, and energy companies including Inpex. Concurrently, market participants have observed a rotation from high-growth tech names to more traditionally undervalued segments, signaling balanced participation in the market’s advance.
In parallel, Taiwan’s stock market captured global attention as its NT ratio—a key indicator of price-to-earnings multiples adjusted for net tangible assets—experienced a pronounced uptick. The Taiwan Capitalization Weighted Stock Index (TAIEX) surpassed the 26,000 intraday milestone, driven by AI hardware manufacturers and semiconductor companies. For example, Compal Electronics surged with its recent announcement of a NT$100 billion AI server equipment order, underscoring explosive demand in AI infrastructure. These moves coincided with Nvidia’s monumental $100 billion global AI investment plans, catalyzing broad-based enthusiasm for AI-related equities on the island.
Underlying these developments is the growing primacy of artificial intelligence as a transformative economic and technological force. The Nikkei's resurgence partially reflects investors’ optimism regarding Japan’s participation in AI-driven industrial innovation. Meanwhile, Taiwan’s soaring NT ratio highlights a speculative tilt toward firms leveraging AI hardware and semiconductor capabilities essential for next-gen computing demands.
Analyzing these phenomena in context, several factors have accelerated this momentum. In Japan, rising commodity prices amid supply constraints have bolstered traditional industrial sectors, rebalancing investor portfolios away from costly growth stocks and reducing headline volatility. Simultaneously, accommodative monetary policies regionally and robust corporate earnings growth have sustained investor appetite despite global macroeconomic uncertainties such as rising U.S. bond yields and geopolitical risks under President Donald Trump’s administration.
Taiwan’s market dynamic, however, presents a more nuanced risk-reward profile. The NT ratio surge clearly indicates heightened price-to-book valuations, often associated with speculative excess. While driven by genuine AI demand and unremitting global technological investments (notably from dominant players like Nvidia and TSMC), such valuation expansions warrant caution. Even marginal adverse news—be it rising U.S.-China trade tensions, tighter U.S. monetary policy, or supply chain disruptions—could trigger sharp corrections in these richly priced sectors.
This juxtaposition between Nikkei’s measured yet steady ascent and Taiwan’s exuberant AI-led rally underscores a crucial trend in Asian equity markets: technological innovation, spearheaded by AI adoption, is a significant growth driver, but its rapid elevation inflates vulnerability to profit-taking and increased volatility.
Looking forward, the Nikkei's near-record levels suggest continued bullishness supported by diversified sector leadership, with cyclical plays capitalizing on global commodity trends and domestic stimulus policies. Japan’s participation in AI-related industrial upgrades, including electrification and robotics, should foster earnings resilience.
Conversely, Taiwan’s AI-driven valuation spike beckons astute risk management. Investors should monitor US Federal Reserve signals, China-Taiwan cross-strait developments, and semiconductor supply dynamics. Sustainable growth will depend on balancing innovation-led expansion with fundamentals and macroeconomic stability.
Overall, these intertwined narratives reveal a broader Asian market architecture where AI catalyzes profound shifts in investment patterns and valuation metrics. While opportunities abound in this high-growth theme, careful assessment of geopolitical and economic headwinds is essential to navigate this complex landscape in late 2025 and beyond.
According to Reuters, strategic rotation in Japan’s Nikkei and Taiwan’s AI valuation surge exemplify a dual-market re-rating propelled by technological and commodity-driven forces, reinforcing Asia’s leadership in next-generation innovation yet signaling caution against potential overheating in AI-related sectors.
