The September Effect: Why Wall Street Braces for a Storm

Why does September have a bad reputation on Wall Street? In this episode George Mayfield and Autumn Bennett explore decades of data showing September as the weakest month for stocks, the theories behind the ‘September effect’ (seasonality, rebalancing, and psychology), and how this perceived pattern can become a self-fulfilling prophecy. They explain historical stats, the strong rebound Oct–Jan, and practical strategies for investors—dollar-cost averaging, maintaining a long-term perspective, having cash ready, diversification, and disciplined planning—plus a bonus tip on using seasonality to your advantage.
