Major shakeup coming to the S&P 500 index. Three new names are joining the club: Carvana ($CVNA), Comfort Systems ($FIX), and CRH ($CRH) are getting promoted into the benchmark.

Meanwhile, LKQ Corporation ($LKQ), Solventum ($SOLS), and Mohawk Industries ($MHK) are getting the boot from the index tracked by $SPY.

These index reshuffles always trigger interesting trading dynamics. Passive funds tracking the S&P 500 will be forced buyers of the incoming stocks and sellers of the outgoing ones. Could create some short-term price action worth watching if you're positioned in any of these names.
