S&P Dow Jones Indices announced changes to its S&P 500, S&P 100, and other indices. Bloom Energy (BE), Everpure, and Illumina (ILMN) will join the S&P 500, replacing Molson Coors, The Trade Desk, and Builders FirstSource. Four tech firms will join the S&P 100, replacing four non-tech companies. Changes take effect September 21, 2026.
How this was made
The 30-second read
Why it matters
Mechanical fund flows from index inclusion/exclusion drive short‑term price moves for the listed companies.
Market read
Index changes will cause short‑term buying/selling pressure for 12 listed firms as funds rebalance.
What to watch
Potential tax‑loss harvesting by funds could offset buying pressure; market may focus on larger macro events.
