Robert Half Inc., Comerica Inc., and Illumina Inc. are being removed from the S&P 500 to make room for the new additions: KKR & Co. Inc., CrowdStrike Holdings, Inc., and GoDaddy Inc.

To be eligible for inclusion in the S&P 500 index, a company must meet the following criteria:
Market Capitalization: A company must have a market capitalization of at least $8.2 billion. Market capitalization is calculated by multiplying the number of outstanding shares by the current share price.
Liquidity: The company's shares must be highly liquid, with a minimum of 250,000 shares trading in the six months leading up to the evaluation date. Additionally, trading volume must exceed 100% of its float each year.
Public Float: At least 50% of the company's outstanding shares must be available for public trading. This ensures that the company is widely held and not closely held by a few shareholders.
Profitability: A company must have positive as-reported earnings over the most recent quarter, in addition to over the four most recent quarters added together.
U.S. Company: The company must be based in the U.S., file 10-K annual reports with the SEC, and have a "plurality" of assets and revenue in the United States. It must also be listed on an eligible exchange such as the NYSE or NASDAQ.
These criteria ensure that the S&P 500 index includes large, well-established, and financially sound companies that are representative of the U.S. economy.

In the latest quarterly update, KKR & Co. Inc., CrowdStrike Holdings, Inc., and GoDaddy Inc. are being added to the S&P 500. These companies will replace Robert Half Inc., Comerica Inc., and Illumina Inc. The changes are set to go into effect prior to the open of trading on Monday, June 24.
