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

Live News

Stock markets across Asia and the United States have surged to unprecedented levels, effectively disregarding the disruptions caused by the Iran conflict that began in March. The Strait of Hormuz, a critical global oil chokepoint, effectively closed at the start of March, removing approximately one-fifth of worldwide oil supply from the market. Despite this significant supply shock, investor enthusiasm has quickly pivoted toward artificial intelligence and semiconductor opportunities. South Korea's Kospi index and Taiwan's Taiex both achieved record highs on Wednesday, while Japan's benchmark Nikkei 225 reached its own record high last week. The S&P 500 and Nasdaq Composite in the United States also closed at record levels during the same trading session. Taiwan's Taiex has gained 16% since the conflict began and is up 42% for the year, while the Nikkei has recovered from an initial 13% decline to post a 1% gain since March and an 18% year-to-date advance. The momentum has been particularly pronounced in Korea, where the Kospi has surged nearly 76% in 2025, marking its strongest annual performance since 1999. On Thursday, Korea's equity market capitalization surpassed Canada's, elevating it to become the world's seventh-largest stock market. Taiwan similarly overtook Canada in April to become the sixth-largest globally.

Key Highlights

The AI-driven rally has emerged as the dominant force reshaping global equity markets, effectively overshadowing concerns about energy supply disruptions and their potential economic consequences. Semiconductor companies have been the primary beneficiaries, with companies specializing in advanced chips seeing substantial appreciation as demand for AI infrastructure accelerates. The regional divergence in market performance has become increasingly pronounced. Asian markets heavily exposed to semiconductor manufacturing and AI development have outperformed dramatically, while European indices remain below their pre-war levels despite facing similar energy vulnerabilities. Germany and Europe's benchmark STOXX 600 indexes both remain in negative territory since the conflict began. Energy dynamics have created asymmetric impacts across regions. The United States, as a net energy exporter, has been relatively insulated from oil price increases, while energy-importing Asian economies have absorbed higher input costs. Paradoxically, this energy pressure has not prevented Asian equity markets from reaching new highs, suggesting that AI-related earnings expectations are currently dominating investor decision-making. The composition of major indices has amplified these trends. According to industry analysis, artificial intelligence, semiconductor companies, and data center-related businesses now represent approximately 50% of Japan's Nikkei 225 weighting. This concentration means that AI momentum directly translates into index-level performance. South American markets have benefited differently, with energy-exporting nations like Brazil experiencing gains from elevated commodity prices. The Bovespa Index is up 16% year-to-date, reflecting how regional economic structures continue to influence market outcomes despite the global AI narrative.

Expert Insights

The market rebound reveals a fundamental shift in how investors are evaluating geopolitical risk in the modern era. According to market strategists at major financial institutions, the artificial intelligence capital expenditure cycle has emerged as the primary driver of equity valuations, effectively drowning out traditional concerns about energy supply disruptions and their macroeconomic implications. The phenomenon reflects broader structural changes in the global economy. While Asian economies remain heavily dependent on imported energy, their dominant positions in semiconductor manufacturing and technology supply chains have created offsetting tailwinds. When oil prices rise, these economies face higher input costs; however, when AI-related demand surges, they benefit from their integral position in the technology ecosystem. The European underperformance highlights this dynamic most clearly. European markets face similar energy vulnerabilities as their Asian counterparts but lack equivalent exposure to semiconductor and AI infrastructure companies. This structural difference explains why European indices have failed to recover to record levels despite the same global conditions affecting other regions. Investors appear to be gravitating toward markets where earnings delivery is most visible and predictable. The artificial intelligence ecosystem, concentrated in North American technology companies and Asian semiconductor manufacturers, has become the preferred destination for global capital flows. This concentration suggests that AI-related earnings expectations are pricing in substantial future growth, raising questions about sustainability if implementation timelines lengthen or competitive pressures intensify. The speed of the Asian market recovery has been particularly striking given the severity of the initial shock. When the Hormuz strait closure removed significant oil supply from global markets, conventional wisdom suggested a prolonged period of economic and market stress. Instead, investors rapidly refocused on longer-term growth opportunities, effectively treating the energy disruption as a temporary phenomenon rather than a structural challenge. Looking ahead, market performance will likely depend on whether AI-related capital expenditure continues at projected levels and whether semiconductor demand sustains its current trajectory. The divergence between AI-exposed and non-exposed markets suggests that the technology transformation is creating increasingly distinct winners and losers across regional economies. This pattern may persist as long as artificial intelligence investment remains the dominant theme in global capital markets, regardless of developments in other areas such as energy supply or geopolitical stability.
