Solstice and Qnity Set to Join S&P 500 in First Index Changes Since September
The S&P 500 is poised for its first composition shift since September, with Solstice Advance Materials and Qnity Electronics joining the benchmark index. Solstice, spun off from Honeywell International, will replace CarMax under the ticker "SOLS," while Qnity, a DuPont de Nemours spinoff, takes Eastman Chemical's spot with the symbol "Q." Both changes reflect corporate restructuring rather than market performance.
Index adjustments Ripple through financial markets—the S&P 500 underpins trillions in indexed assets. CarMax and Eastman will transition to the S&P SmallCap 600, demonstrating how corporate actions cascade across market segments. These moves highlight the dynamic nature of equity benchmarks as living ecosystems.
