Super Micro surges as AI server maker set to join S&P 500

Super Micro and Deckers Outdoor Corp will be added to the S&P 500 prior to the start of trading on Monday, March 18, coinciding with a quarterly rebalance of Wall Street's most widely followed stock benchmark, S&P Dow Jones Indices said in a news release. Those two companies will replace Whirlpool Corp and Zion Bancorporation, S&P Dow Jones Indices said. Index funds that track the S&P 500 are among the most popular investment tools on Wall Street, and those funds will have to purchase shares of Super Micro and Deckers in order to stay aligned with the benchmark's composition.
