News Analysis: Market rebound: Why some stocks are looking past the Iran war - Options Activity

Live News

Stock markets across Asia and the United States have achieved record highs in recent trading sessions, demonstrating resilience in the face of the Iran war's economic disruptions. South Korea's Kospi index and Taiwan's Taiex both reached all-time highs on Wednesday, while Japan's Nikkei 225 touched a record level the previous week. The American markets mirrored this performance, with both the S&P 500 and Nasdaq Composite closing at record levels during the same trading session. The rally has proven particularly striking given that Asian economies face substantial vulnerabilities from the conflict. The Strait of Hormuz, through which approximately one-fifth of global oil supplies transit, effectively closed at the beginning of March following the outbreak of hostilities. Japan, South Korea, and other regional economies depend heavily on Middle Eastern oil imports, yet their equity markets have surged regardless. South Korea's equity market capitalization has grown substantially, surpassing Canada's to become the world's seventh-largest market. Taiwan similarly overtook Canada to claim the sixth position among global equity markets. The gains have been particularly pronounced in semiconductor-related sectors, with leading chip manufacturers driving significant portions of the index advances. European markets, by contrast, have failed to recover to pre-conflict levels despite facing similar energy supply challenges. Germany's Dax remains down more than one percent since the war began, while the broader European STOXX 600 index continues trading below its previous peaks.

Key Highlights

The AI revolution has emerged as the dominant force reshaping global equity markets, with technology and semiconductor stocks driving index gains across multiple regions. Artificial intelligence, semiconductor companies, and data center-related enterprises now constitute approximately 50 percent of Japan's Nikkei 225 weighting, reflecting the fundamental transformation in market composition. South Korea's Kospi index has recorded exceptional gains, climbing nearly 76 percent during 2025, marking its strongest annual performance since 1999. The index has already advanced 75 percent in the current year. Taiwan's Taiex has appreciated 16 percent since the conflict began and 42 percent year-to-date. Japan's Nikkei 225, despite initial losses of 13 percent in March, has recovered to post a 1 percent gain since the war commenced and an 18 percent advance for the year. The divergence between regional markets reflects fundamental differences in economic structure. The United States functions as a net energy exporter, insulating its economy from oil price volatility, while Asian manufacturing powerhouses such as Japan and South Korea remain heavily dependent on imported energy. This energy vulnerability should theoretically weigh on Asian markets, yet the AI narrative has proven sufficiently compelling to overcome these concerns. European markets tell a different story, with the STOXX 600 down nearly 2 percent since the conflict began. The region lacks the AI-driven tech concentration found in American and Asian markets, leaving it more exposed to traditional economic risks without the counterbalancing technology premium. Energy-exporting nations in Latin America have fared better, with Brazil's Bovespa posting a 16 percent gain for the year, though the index remains roughly flat since the conflict started.

Expert Insights

The current market dynamic reflects a profound shift in investor priorities, where the promise of artificial intelligence has eclipsed traditional concerns about geopolitical instability and energy security. Daniel Skelly, head of Morgan Stanley's wealth management market research and strategy team, noted that different regions possess distinct potential tailwinds, yet much of Asia appears positioned to benefit significantly from the AI capital expenditure cycle. This assessment aligns with observable market behavior, as investors continue to gravitate toward companies positioned to benefit from infrastructure buildout associated with artificial intelligence deployment. The phenomenon underscores a critical distinction in how global markets are pricing risk and opportunity. Jim Reid, head of global macro research at Deutsche Bank, observed that Asian markets are responding favorably to developments in peace negotiations alongside momentum in the semiconductor sector. This dual focus on geopolitical resolution and technological advancement indicates that investors are simultaneously seeking comfort in reduced uncertainty while pursuing growth in high-potential sectors. Arun Sai, senior multi-asset strategist at Pictet Asset Management, offered additional perspective on the concentration of market enthusiasm. Investors have retreated to familiar territory where earnings delivery remains evident, concentrating their exposure in American technology firms and the broader AI ecosystem. This preference pattern reveals how artificial intelligence has become the primary framework through which market participants evaluate investment opportunities across geographies. The structural implications extend beyond immediate market performance. The dominance of AI-related stocks in major indices creates feedback loops where continued gains attract additional capital flows, reinforcing concentration in technology-related sectors. This dynamic may persist as long as earnings from AI-focused companies continue meeting or exceeding expectations. Looking toward the remainder of the current period, several factors warrant monitoring. Peace negotiations and their potential outcomes could influence market direction, particularly if hostilities show signs of resolution. The trajectory of semiconductor demand and artificial intelligence infrastructure investment will likely remain the primary determinant of equity market performance in Asia and the United States. Meanwhile, European markets may continue trailing their global counterparts unless technology sector exposure increases materially. The divergence between energy-importing regions benefiting from AI adoption and energy-exporting regions experiencing commodity tailwinds reflects a more complex global economy than simple geopolitical correlations would suggest. Markets are essentially voting on the future relative to the present, and that vote currently strongly favors artificial intelligence as the defining theme of economic transformation. For market participants, the implications are clear: AI exposure has become a critical factor in portfolio positioning, regional exposure matters significantly, and the capacity to look past traditional risk factors when technology narratives prove compelling remains an essential characteristic of current market dynamics.
