News Analysis: Market rebound: Why some stocks are looking past the Iran war - Sector Perform

Live News

The global equity rally has extended beyond the United States, with Asian markets posting record highs despite significant exposure to oil supply disruptions stemming from the Iran conflict. South Korea's Kospi index and Taiwan's Taiex both reached unprecedented levels, while Japan's benchmark Nikkei 225 surpassed its previous record in mid-April. The S&P 500 and Nasdaq Composite similarly achieved new record highs during the same trading session. The Strait of Hormuz, a critical global oil shipping route, effectively closed in early March following the outbreak of hostilities with Iran, removing approximately one-fifth of global oil supply from markets. Japan, South Korea, and much of Asia depend heavily on Middle Eastern oil imports, yet their equity markets have surged rather than contracted in response to these supply disruptions and the subsequent price pressures. The rally has been particularly pronounced in the semiconductor sector, with chipmakers driving substantial portions of the gains across Asian markets. South Korea's equity market capitalization surpassed Canada's to become the world's seventh largest, while semiconductor manufacturing capabilities have become increasingly central to regional market valuations. Taiwan's market capitalization also eclipsed Canada's, elevating the island to the world's sixth-largest stock market. Meanwhile, European markets have failed to recover to the same extent, with Germany's Dax remaining down more than 1% since the conflict began. The divergence highlights how artificial intelligence exposure is increasingly determining market performance across global regions.

Key Highlights

The Kospi index has emerged as one of the world's strongest performers, gaining nearly 76% in the current year, marking its most robust annual performance in over two decades. Taiwan's Taiex has demonstrated comparable strength, rising 42% year-to-date and climbing 16% since the onset of the Iran conflict. Japan's Nikkei 225, despite an initial 13% decline through March, has fully recovered and reached record territory, posting a year-to-date gain of 18%. The concentration of AI-related companies within major indices has become increasingly significant. According to JPMorgan Chase estimates, artificial intelligence companies, semiconductor firms, and data center operators together constitute approximately 50% of the Nikkei 225's total weighting. This technological concentration has provided a substantial tailwind as demand for semiconductor chips has intensified amid the global push to develop AI infrastructure. The regional performance divergence has been equally striking when examining markets lacking similar AI exposure. Europe's benchmark STOXX 600 index remains nearly 2% below pre-war levels, while Germany's Dax is approximately flat for the year despite the broader global rally. The contrast is particularly notable given that Europe faces similar energy import dependencies as Asia but lacks the technological sector strength that has supported Asian markets. Energy-exporting nations have benefited from the oil supply disruptions, with Brazil's Bovespa Index advancing 16% year-to-date. However, the magnitude of gains in AI-linked markets has significantly outpaced those benefiting from energy price increases, reflecting the market's forward-looking focus on technological transformation rather than immediate commodity dynamics.

Expert Insights

The current market dynamics represent a significant structural shift in how geopolitical risks are being priced and evaluated by global investors. Traditional correlations between energy import dependency and equity market performance have been substantially weakened by the emergence of artificial intelligence as the primary driver of equity valuations across multiple markets. Daniel Skelly, head of market research and strategy at Morgan Stanley's wealth management division, contextualized the regional divergence by noting that Asia's technology exposure positions the region similarly to the United States in benefiting from the artificial intelligence capital expenditure cycle. This assessment suggests that the current rally represents more than a temporary market anomaly but rather a fundamental repricing of technology-enabled growth prospects across major economies. The semiconductor industry has assumed a pivotal role in this transformation. Companies manufacturing advanced chips have become essential infrastructure providers for AI development, creating demand dynamics that transcend traditional cyclical patterns. This structural demand shift has supported valuations even as input costs have risen due to energy price pressures affecting net importing nations. Jim Reid, head of global macro research at Deutsche Bank, attributed Asian market resilience to a combination of peace negotiation optimism and semiconductor momentum, indicating that investors are pricing in both resolution of immediate geopolitical tensions and continued strength in technology sector fundamentals. This dual focus suggests markets are attempting to look beyond current disruptions toward sustained growth trajectories. The AI concentration within major indices raises important considerations regarding portfolio construction and risk management. Arun Sai, senior multi-asset strategist at Pictet Asset Management, noted that investors have retreated to sectors demonstrating actual earnings delivery, with US technology and the broader AI ecosystem representing the primary beneficiaries. This rotation pattern implies that market participants are exercising selectivity based on fundamental performance rather than applying uniform risk assessments across regions and sectors. David Russell, head of global market strategy at TradeStation, offered a particularly pointed characterization of the current landscape, observing that Asia possesses artificial intelligence capabilities despite lacking domestic energy resources, while Latin America benefits from energy exports without comparable technology exposure, and Europe finds itself deficient in both categories. This framework effectively illustrates how the AI revolution has created fundamental asymmetries in growth prospects across global markets. The performance divergence between technology-heavy and traditional economy indices raises questions about long-term sustainability of current valuations. While AI infrastructure spending appears poised for continued expansion, the degree of concentration risk within major indices warrants careful monitoring. Markets that have rallied substantially on AI enthusiasm may face heightened volatility if earnings growth fails to justify current valuation multiples or if interest rate dynamics shift unfavorably for growth-oriented assets. For market participants, the current environment underscores the importance of distinguishing between short-term geopolitical risk sentiment and longer-term structural trends when formulating investment strategy. The resilience of AI-linked markets in the face of genuine supply disruptions suggests that technological transformation remains the dominant market narrative, potentially overriding traditional risk factors for the foreseeable future.
