Index's rebalancing sees Robert Half, Comerica and Illumina dropped from the large-cap benchmark

Cybersecurity company CrowdStrike Holdings Inc., private-equity giant KKR & Co. Inc. and web host GoDaddy Inc. are set to join the S&P 500 index at market open on June 24, index provider S&P Dow Jones Indices said late Friday.

Crowdstrike (CRWD), KKR (KKR) and GoDaddy (GDDY) are more representative of the S&P 500's SPX large-cap range, the index provider said. The trio replaces staffing company Robert Half Inc. (RHI), financial-services company Comerica Inc. (CMA) and biotech firm Illumina Inc. (ILMN) Robert Half and Comerica will move to the S&P SmallCap 600 SML, while Illumina will move to the S&P MidCap 400 MID.

The shares of the three new S&P 500 constituents jumped in the extended session Friday, with KKR leading the way with gains of nearly 8%. KKR shares jumped 10% in premarket trading on Monday, Crowdstrike rose 5% and GoDaddy stock was up 3%.
