Recent analyses indicate a notable shift in market dynamics, with U.S. stocks lagging behind international indices. The S&P 500 has shown a counter-trend move, prompting speculation about a potential breather in this momentum. Year-to-date, U.S. stocks are trailing the MSCI World ex-U.S. index by 5%, attributed to stretched valuations and a less dominant technology sector. Despite this, U.S. earnings beats and growth differentials continue to support the domestic market. Observations also highlight that U.S. equities still account for approximately 80% of global equity flows year-to-date. Additionally, exchange-traded funds (ETFs) have seen robust inflows, totaling $162 billion so far this year, with projections suggesting a record $1.3 trillion by year-end. The ongoing trends raise questions about the sustainability of U.S. market dominance amid increasing international investment appeal.
