'It's Controversial': The Debate Over SpaceX's IPO Rule Change
NOW PLAYING'It's Controversial': The Debate Over SpaceX's IPO Rule Change
Late Thursday, S&P Dow Jones said it would not fast-track SpaceX and other upcoming huge IPOs into the S&P 500.
Other Notable S&P Index Changes
Roku is jumping straight into the S&P Midcap 400, along with Viavi Solutions ( VIAV) and Coeur Mining ( CDE), while Semtech ( SMTC), Sanmina ( SANM) are moving up from the S&P SmallCap 600.
Pool and Campbell's are dropping all the way down to the 600.
Marvell stock jumped 6% in late trade while fellow AI hardware play Flex climbed 2%. Streaming media platform Roku gained nearly 5%. Coeur Mining advanced nearly 3%. Viavi lost a fraction.
Semtech and Sanmina fell slightly overnight. More funds track the S&P SmallCap 600 than the S&P MidCap 400, so stocks moving up from the 600 to 400 often see a one-off decline.
