Marvell and Flex rise on S&P 500 inclusion announcement
Chipmaker Marvell Technology and electronics manufacturer Flex are jumping 7% and 3%, respectively, in premarket trading on Monday after S&P Dow Jones Indices announced late on Friday that the two companies are set to join the S&P 500 benchmark index.
Replacing Pool Corp. and Campbell’s in the S&P 500, Marvell and Flex’s addition will be effective from June 22, per a press release from the provider, which assesses and updates the index on a quarterly basis.
Marvell has been one of the leading candidates for inclusion across the last few quarterly index rebalances. The company has ballooned into a $230 billion chip giant of late, thanks to the wider AI boom, investors chasing momentum, and, yes, Jensen Huang. Flex, which has been part of the S&P MidCap 400 Index since 2024, has also grown recently, having played a part in the data center boom with a portfolio that spans across infrastructure and cooling systems.
With today’s premarket movement taken into account, MRVL has now risen almost 40% in the last week alone.
