US Stock Market: Russell index revamp set to trigger massive trading as SpaceX joins benchmark

The Russell indexes will undergo their first-ever semi-annual reconstitution this June, with SpaceX fast-tracked into the Russell 1000 following its IPO, marking the debut of FTSE Russell's new fast-entry rule. Classification shifts include Microsoft and Apple entering both Growth and Value indexes, Amazon moving further toward Value, and Alphabet and AMD becoming fully Growth stocks. A total of 62 firms will join the Russell 1000, with Goldman Sachs strategists expecting semiconductors to record the largest weighting increase, as Friday's close is set to drive one of the year's heaviest liquidity events.
