S&P 500 Marks Four-Year Bull Market Anniversary

The S&P 500 index marked a bull market anniversary, recording returns that more than doubled investor money over the past four years. This growth resulted from a combination of resilient consumer spending, strong labor markets, and double-digit earnings growth. The AI revolution across multiple sectors also served as a primary driver for these gains.

Market capitalization has become increasingly concentrated among a small number of companies with global technology distribution. This concentration is viewed as a reflection of strong profits rather than an increase in systemic risk. Analysts indicate that a deterioration in market breadth is a consequence of higher interest rates rather than a signal of slowing economic growth.
