News Analysis: Market rebound: Why some stocks are looking past the Iran war - Weak Earnings Momentum

Live News

Stock markets across Asia and the United States have achieved unprecedented highs, signaling investor confidence that transcends the geopolitical tensions stemming from the Iran conflict. South Korea's benchmark Kospi index and Taiwan's Taiex index both recorded all-time highs this week, while Japan's Nikkei 225 surpassed its previous record in April. The simultaneous achievement across multiple major markets underscores a broader trend of technology-weighted indices outperforming traditional economic indicators. The Strait of Hormuz, which handles approximately one-fifth of global oil shipments, effectively closed in early March following the outbreak of hostilities, causing initial market turbulence. Japan's Nikkei 225 declined 13% by the end of March, and global indices experienced significant volatility. However, subsequent weeks have witnessed a swift reversal, with markets erasing war-related losses and pushing to new record levels. The semiconductor sector has emerged as the primary driver of this recovery, with Asia's chip manufacturers experiencing substantial valuation increases. South Korea's equity market has gained nearly 76% in the year, marking its strongest performance since 1999, while Taiwan's market capitalization has propelled the region to become the world's sixth-largest stock market. European markets, by contrast, remain below their pre-conflict levels, with Germany's Dax still down more than 1% since the war began.

Key Highlights

The AI sector's dominance in global equity markets has become increasingly pronounced, with artificial intelligence, semiconductor companies, and data center-related enterprises now comprising approximately 50% of the Nikkei 225's weighting according to analysis from major financial institutions. This technological concentration has fundamentally altered how markets respond to traditional risk factors such as energy supply disruptions. Energy dynamics have created divergent outcomes across regions. The United States, as a net energy exporter, has experienced relatively limited economic impact from the oil supply shock. Conversely, major Asian economies including Japan and South Korea, which depend heavily on Middle Eastern oil imports, have faced more significant cost pressures. Despite these headwinds, stock markets in these import-dependent nations have surged, demonstrating how AI optimism has overwhelmed energy cost concerns in investor sentiment calculations. Regional market performance has varied substantially based on technological exposure. European benchmarks including the Dax and the STOXX 600 continue to trade below their pre-conflict levels, reflecting the region's limited participation in AI-driven growth. Meanwhile, energy-exporting nations in Latin America, such as Brazil, have benefited from elevated petroleum prices, with the Bovespa advancing 16% year-to-date. The semiconductor industry's strategic importance has been validated by market capitalization milestones. Major Asian chip manufacturers have achieved valuations exceeding one trillion dollars, establishing themselves among the world's most valuable corporations. This positions the sector as a primary beneficiary of the global AI infrastructure buildout.

Expert Insights

The current market environment represents a significant evolution in how geopolitical events affect investor behavior. Historically, supply disruptions of this magnitude would have triggered sustained market declines, particularly in import-dependent economies. The present scenario demonstrates that when structural growth narratives prove sufficiently compelling, they can effectively decouple equity performance from traditional macroeconomic constraints. The global AI capital expenditure cycle has emerged as the defining theme of this market cycle. Major financial institutions have noted that Asia, similar to the United States, stands positioned to benefit substantially from the technology sector's expansion. This represents a fundamental shift in regional economic narratives, where manufacturing capabilities are transitioning from traditional industries toward advanced technology production. The concentration of market gains in technology-related sectors carries important implications for portfolio strategy. While this concentration has generated exceptional returns for investors with appropriate allocations, it also creates elevated correlation risk. Should AI-related valuations face correction pressures, the concentrated nature of current gains could amplify market volatility. European markets' relative underperformance highlights the structural challenges facing economies with limited technology exposure. The region faces a dual challenge: it bears similar energy dependency risks as Asian importers while lacking the compensating technological upside that has supported Asian markets. This dynamic suggests continued divergence between technology-heavy and traditional economic indices. Market positioning indicates substantial optimism regarding conflict resolution, with investors demonstrating willingness to overlook persistent geopolitical risks in favor of growth narratives. While peace efforts have provided additional tailwind to market sentiment, the durability of current valuations ultimately depends on whether AI infrastructure investment continues at projected levels and whether earnings growth justifies present pricing multiples. Looking ahead, the divergence between AI-exposed and non-exposed markets is likely to persist, particularly if energy prices remain elevated given the structural supply constraints. Portfolio construction should account for the concentration risk inherent in technology-dominated indices while acknowledging that fundamental drivers supporting AI-related equities remain intact. The market's ability to absorb geopolitical shocks through technology-driven narratives suggests that investors should carefully evaluate their technological exposure relative to broader market benchmarks.
