Market Warning for September: Ryan Detrick, Chief Market Strategist at Carson Group, cautioned that a strong performance in August, where the S&P 500 gained 1.9% and reached five all-time highs, historically leads to negative returns in September, with a 100% failure rate in similar past instances from 1950-2025.

Historical Trends and Market Context: September is typically the worst month for the S&P 500, with an average return of -2.3% when August meets the outlined criteria, and a 56% decline rate since 1928, suggesting investors should be cautious as markets face potential Federal Reserve rate cuts.
