Paycom Software Inc. has been selected for inclusion in the S&P 500, becoming the fifth Oklahoma business on the widely followed index of large U.S. publicly traded companies.
S&P Dow Jones Indices announced the decision after markets closed Wednesday. Before the markets open on Jan. 28, Paycom will replace WellCare Health Plans Inc., which will be acquired by another S&P 500 company.
Paycom will join Oklahoma companies Helmerich & Payne Inc., ONEOK Inc., Williams Cos. Inc. and Devon Energy Corp. on the index.
The human capital management company closed at more than $300 a share for the first time Wednesday, shortly before the announcement. In after-hours trading, the stock price jumped more than 4% to $317 per share.
