Investing.com -- Solstice Advanced Materials Inc (NASDAQ:SOLSV) stock surged 12.8% after S&P Dow Jones Indices announced the company will join the S&P 500 index, while CarMax Inc (NYSE:KMX) shares fell 0.5% in after-hours trading Monday following news it will be removed from the benchmark index.

The changes will take effect before market open on October 31, following Honeywell International Inc’s (NASDAQ:HON) planned spinoff of Solstice Advanced Materials, expected to complete on October 30. Honeywell will maintain its positions in both the S&P 500 and S&P 100 following the transaction.

CarMax will be downgraded to the S&P SmallCap 600, replacing USANA Health Sciences Inc (NYSE:USNA), which dropped 1.7% on the news. According to S&P Dow Jones Indices, both companies "no longer represent their respective market cap spaces."

In a separate announcement, Qnity Electronics Inc (NYSE:Q) will also join the S&P 500 before trading begins on November 4, replacing Eastman Chemical Co (NYSE:EMN). This addition follows DuPont de Nemours Inc’s (NYSE:DD) planned spinoff of Qnity Electronics, scheduled for November 3. DuPont will remain in the S&P 500 after completing the spinoff.

Eastman Chemical will move to the S&P SmallCap 600, replacing Caleres Inc (NYSE:CAL), which fell 1.5% following the announcement. The index provider indicated that both Eastman Chemical and Caleres no longer represent their respective market capitalization segments.

Index inclusion typically drives significant stock movements as funds tracking the benchmarks must adjust their holdings to reflect the changes.
