March 7 (Reuters) - Shares of DoorDash ( DASH ),

Williams-Sonoma ( WSM ), Expand Energy ( EXE ) and TKO Group ( TKO )

rose in extended trade on Friday after an announcement

they would join the S&P 500.

The four companies will join Wall Street's most widely

followed stock benchmark before the start of trading on Monday,

March 24, S&P Dow Jones Indices said in a news release.

DoorDash ( DASH ) jumped 7.5%, Williams-Sonoma ( WSM ) rose 2.4%, Expand

Energy ( EXE ) added 1.5% and TKO Group ( TKO ) gained 2.6%.

They will replace Borgwarner Inc ( BWA ), Teleflex Inc ( TFX )

, Celanese Corp ( CE ) and FMC Corp. ( FMC )

Index funds that track the S&P 500 are among the most

popular investment tools in the U.S. stock market, and those

funds will have to purchase shares of the newly added companies

in order to stay aligned with the benchmark's composition.
