S&P 500 Equal Weight Index Falls 2%

The equal-weight gauge is the cleaner read on breadth, so a 2% drop says the selling was democratic rather than a megacap story — a different signal than a cap-weighted decline that a handful of names can distort. That distinction matters most for anyone treating index-level performance as a proxy for the average stock. With no timing or drivers given, the cause remains unattributed, and whether breadth continues to deteriorate independently of the cap-weighted index is the open question worth tracking.
