May 2026 Recap
A monthly review of market performance, economic conditions, and the key trends shaping investor sentiment.
Issued June 4, 2026
Market Overview
Resilient Markets Despite Persistent Concerns
May was characterized by a surprisingly resilient stock market despite persistent inflation concerns, geopolitical tensions, and uncertainty surrounding Federal Reserve policy. The S&P 500 and Nasdaq continued their advance, supported by strong corporate earnings and ongoing investment in artificial intelligence infrastructure.
While economic growth remained positive, inflation pressures proved more stubborn than many investors expected. Energy prices climbed during the month as tensions in the Middle East blocked global oil supplies. At the same time, labor markets remained relatively healthy and consumer spending continued to support economic activity.
Bond markets were more challenged as investors reduced expectations for near-term Federal Reserve rate cuts. Treasury yields moved higher, creating headwinds for fixed-income investors but also providing attractive yields for those seeking income opportunities.
This month’s themes:
Equity markets continued to show strength, inflation remained stubborn, bond yields moved higher, and artificial intelligence investment continued to be a major driver of market enthusiasm.

Final Thoughts
Markets Continue to Climb a Wall of Worry
May demonstrated once again that markets often climb a wall of worry. Despite concerns surrounding inflation, interest rates, and global events, investors continued to focus on strong corporate earnings and economic resilience.
As we enter the second half of 2026, volatility may increase as markets evaluate Federal Reserve policy, the mid-term elections, and the trajectory of inflation. However, maintaining a disciplined, long-term investment strategy remains the most reliable approach to navigating uncertain environments.
