Chart of the Week: Budding Broadening

The AI trade has driven much of the market’s gains this year while pushing market breadth near record lows. Even as the S&P 500 was reaching all-time highs, the median stock remained roughly 15% below its own peak. Recently, however, as the AI theme has come under pressure, non-AI stocks have rallied sharply. While it is still early, we view this rotation as an encouraging sign that market leadership may be broadening, reinforcing the value of diversification in helping investors navigate volatility.
