American Century Investments, an investment management company, released its second-quarter 2026 investor letter for the “American Century Investments Focused Dynamic Growth Fund”. The letter can be downloaded here. U.S. stocks advanced sharply with double-digit quarterly gains largely due to robust earnings, resilient economic data, and momentum in AI-related stocks. However, there was a slight pullback in June as momentum waned and investors anticipated potential interest rate hikes by the Federal Reserve. Growth and AI stocks outperformed value stocks, while large-cap companies generally surpassed small- and mid-cap stocks. Underperformance was noted in healthcare and communication services, while industrials, particularly in aerospace and defense, contributed positively to performance. The fund’s investor class returned 16.38%, slightly below the Russell 1000 Growth Index’s 16.74%. The investment approach focuses on bottom-up financial analysis to identify large-cap companies with long-term earnings growth potential, while aiming to mitigate non-financial risks.
