Global equity markets continue to diverge, with US equities benefiting from renewed artificial intelligence momentum, European markets struggling against higher energy prices and bond yields, and Japan maintaining its position as the strongest-performing major market of 2026.
In the United States, the S&P 500 stands at 7,764.7, up 13.4% year-to-date, while the Nasdaq 100 has gained 20.7% to reach 30,482.4. Both indices are broadly flat today following a powerful session on Monday, when the S&P 500 rose 1.5% and the Nasdaq 100 surged 2.8%—its strongest day since early August.
Artificial intelligence remains the central catalyst. Meta Platforms jumped 11% after its new AI agent, "Muse," topped the Apple App Store charts, while AMD crossed the $1 trillion market capitalization threshold for the first time. Over the past week, the Nasdaq 100 has gained 5.3%, outperforming all other major global indices.
The macroeconomic environment remains more complex. The Federal Reserve delivered its first rate hike in more than three years last Wednesday, a move that was fully anticipated by markets. Chairman Kevin Warsh's subsequent comments initially unsettled investors before renewed AI enthusiasm took over. Oil also remains an important cross-current, with Brent crude above $100 per barrel as markets continue to follow US-Iran diplomatic developments.
The concentration of recent gains has created challenges for active managers. Only 22% of large-cap mutual funds outperformed their benchmarks in August, the weakest performance in more than four years, as returns became increasingly concentrated among mega-cap technology companies.
European equities continue to lag their US counterparts. The Stoxx 600 stands at 641.0, up 8.2% year-to-date, while Germany's DAX has gained 4.0%. France's CAC 40 remains essentially flat for the year. All three are modestly lower today following a difficult month marked by a bond-market selloff, elevated oil prices, and renewed inflation concerns.
Technology is providing some support, with ASML among the leading contributors as Meta's AI success lifts broader sector sentiment. Strategists remain constructive on the region, although investor positioning has deteriorated significantly. A Bank of America fund manager survey showed global funds moving to a 5% underweight position in Eurozone equities from a 6% overweight just one month earlier.
The FTSE 100 has demonstrated greater resilience, gaining 8.0% year-to-date. Its defensive and energy-heavy composition has provided a buffer against recent bond and oil volatility, allowing it to outperform several continental European markets over the past three months. UK fiscal conditions nevertheless remain an important consideration, with public sector net debt reaching approximately 93.8% of GDP at the end of August.
Chinese equities remain the weakest major markets year-to-date. The CSI 300 is down 1.8%, while the Hang Seng has declined 2.2%. Both have gained approximately 2% over the past week, partly supported by optimism surrounding the upcoming US-China summit and continued mainland buying of Hong Kong-listed shares.
The underlying Chinese economic backdrop remains challenging. August retail sales increased only 0.4% year-on-year, while fixed-asset investment declined 7.2% during the first eight months of the year. Despite strong second-quarter corporate profit growth, concerns surrounding consumer demand and returns from AI investment continue to weigh on market sentiment.
Japan remains the global standout. The Nikkei 225 is up 29.2% year-to-date, while the TOPIX has gained 20.0%. Both markets have recovered over the past week following a turbulent summer characterized by Yen volatility and expectations for higher interest rates. The Bank of Japan's latest rate increase and subsequent currency-market developments remain key factors for Japanese equities, particularly technology and semiconductor companies.
Overall, global equity markets continue to be shaped by sharply different regional and sector dynamics. AI remains the dominant driver of US performance, energy and rates are constraining European markets, China continues to face domestic growth challenges, and Japan retains its position as the strongest major equity market of the year.
