$100 billion has accumulated in the equal-weight S&P 500's flagship trade, and the strategy is running ahead of the broader U.S. equity market in 2026. Money has flooded into equal-weight exchange-traded funds throughout the year.
Equal-weight construction assigns each S&P 500 constituent an identical portfolio weight, a direct contrast to cap-weighted indexing. In a cap-weighted index, the largest stocks by market value command the largest allocations and drive the bulk of index returns. Equal-weight removes that concentration. Each rebalancing cycle resets every name back to its equal share.
The $100 billion in the flagship trade is the headline figure in a year-long flow into the format. The strategy's 2026 market lead has held alongside those inflows.
