Markets continue to rally on AI optimism and expectations of easing monetary policy, but investors should watch for signs of breadth divergence -- the rally remains concentrated in mega-cap tech while broader market indicators suggest caution. The S&P 500's record-close with narrow leadership is a pattern that has preceded at least two significant corrections in this cycle. Traders should position defensively by reducing concentration risk and considering protective puts on high-beta names.
