Markets continued to feel the effects of AI‑related volatility for a second straight week, as investors work to determine how AI could disrupt traditional business models. Interestingly, overall market breadth has remained strong, with advancers outpacing decliners with more stocks having advanced than declined in 8 of the 10 trading days of February 2026—even though the S&P 500 itself closed positive on just four of those days. This broader participation helped the S&P 500 Equal Weight Index outperform the market‑cap‑weighted S&P 500 by 1.6% for the week.
