Markets Advance to New Highs as Narrow Leadership and Resilient Data Shape the Outlook

May 11, 2026

Executive Summary

Markets continue to demonstrate resilience, advancing to new highs despite narrow leadership, persistent geopolitical uncertainty, and an evolving policy backdrop. Strong corporate earnings, particularly in technology and AI-related sectors, remain the primary driver of equity performance, while labor market data suggest the economy is cooling gradually rather than deteriorating. The sustainability of the rally will depend on continued earnings growth, stable employment conditions, and the absence of a meaningful escalation in geopolitical tensions.

Key Takeaways:

• Equities reached new highs, with the S&P 500 and NASDAQ Composite both advancing for a sixth consecutive week and closing at record levels.
• Market leadership remains narrow, with just 15 stocks accounting for more than 75% of the S&P 500’s return since the March 30th low, led largely by mega-cap technology, semiconductors, and AI-related companies.
• Corporate fundamentals remain supportive, with strong earnings expectations and record-high operating margins helping sustain elevated valuations.
• Labor market data remain constructive, pointing to a “low-hiring, low-firing” environment in which job growth has moderated but layoffs remain contained.
• Policy and geopolitical risks remain important, with U.S.–Iran developments and President Trump’s upcoming meeting with President Xi Jinping likely to influence market sentiment, trade expectations, and energy-related risks.

Financial Markets

U.S. equity markets extended their advance for a sixth consecutive week, with both the S&P 500 and NASDAQ Composite closing at new all-time highs. The rally’s persistence reflects a market increasingly willing to look past geopolitical uncertainty and focus on earnings strength and forward expectations. Recent developments in U.S.-Iran relations, including intermittent exchanges of attacks, have had only a muted impact on risk assets. Markets appear to be discounting a path toward stabilization, supported by reports of a potential memorandum of understanding and continued adherence to a fragile ceasefire.

Under the surface, however, market dynamics remain increasingly concentrated. Since the March 30^th low, just 15 stocks have accounted for more than 75% of the S&P 500’s total return, underscoring the narrow breadth of the rally. Mega-cap technology and semiconductor companies continue to dominate performance, driven by sustained demand for artificial intelligence infrastructure and capital expenditures. This theme has been a defining feature of recent earnings seasons, with technology and communication services expected to account for approximately 64% of total S&P 500 earnings in 2026.

While this concentration raises questions about the durability of the advance, fundamentals remain supportive. Consensus expectations call for earnings growth of approximately 21% for the cap-weighted S&P 500 and 14% for the equal-weighted version in 2026, and 15% and 14%, respectively, in 2027. As we have noted in prior reports, strong earnings growth can sustain elevated valuations, but narrow leadership leaves markets more sensitive to any disappointment among a small group of dominant companies.

Economics

This week’s economic data reinforced a constructive labor market narrative: conditions have cooled gradually but remain fundamentally resilient. Job openings, payroll growth, hiring activity, and jobless claims collectively point to a “low-hiring, low-firing” environment. March JOLTS job openings came in at 6.87 million, modestly above expectations, while the hiring rate improved to 3.5%. April ADP private payrolls rose by 109,000, the strongest gain since January, and nonfarm payrolls increased by 115,000, also ahead of expectations despite modest downward revisions to prior months.

Some softness remains beneath the surface. The unemployment rate edged up to 4.34%, and labor force participation declined to 61.8%, its lowest level since late 2021. Still, key measures of labor-market health remain stable. The prime-age employment-to-population ratio remained at 80.7%, just below recent-cycle highs, while long-term unemployment was unchanged. Layoff data also remains contained. April job cuts rose month over month but declined 21% year over year, and weekly jobless claims remain near multi-decade lows.

Taken together, the data suggest stabilization rather than deterioration. For monetary policy, this is an important distinction. A resilient labor market without accelerating wage pressure reduces the risk of renewed inflation and may give the Federal Reserve greater flexibility to ease policy later this year if conditions warrant. For markets, the balance between moderating growth and stable employment remains a constructive backdrop for risk assets.

Policy

Policy developments remain a key driver of market sentiment, particularly where geopolitics and global trade intersect. President Trump’s planned visit to China later this week, the first by a U.S. president in nearly a decade, represents a significant diplomatic event. Discussions with President Xi Jinping are expected to cover trade, Iran, Taiwan, and emerging risks related to advanced artificial intelligence. China’s role is especially important given its status as a major purchaser of Iranian oil and its potential to encourage diplomatic progress with Tehran.

Economic cooperation is also expected to play a prominent role. Reports suggest China may announce purchases of U.S. goods, including Boeing aircraft, agricultural products, and energy exports, while both countries may establish new forums to support trade and investment. These steps could modestly support global growth and stabilize bilateral relations, though major points of tension remain unresolved. Taiwan remains a central source of friction, and both sides are increasingly focused on the strategic implications of AI. As in prior periods, policy uncertainty remains a persistent source of volatility, but markets have shown an ability to absorb these risks when they do not create sustained disruptions to growth or financial conditions.

Conclusion

Markets continue to demonstrate notable resilience, advancing to record highs despite a complex and evolving backdrop. Strong corporate earnings growth, particularly in technology and AI-related sectors, remains the primary driver of equity performance. At the same time, economic data suggests a stable foundation, with growth moderating but not deteriorating.

However, the current environment is increasingly nuanced. Market leadership remains narrow, geopolitical risks persist, and policy uncertainty continues to shape investor sentiment. While recent data suggest stabilization, overall conviction remains measured, and markets are likely to remain sensitive to both economic releases and geopolitical developments.

Looking ahead, the sustainability of the rally will depend on a delicate balance: continued earnings growth, stable labor market conditions, and the absence of a meaningful escalation in geopolitical tensions. In this setting, a disciplined approach grounded in diversification, quality, and long-term perspective remains essential as investors navigate an expansion that continues, but with narrower margins for error.
