Marvell and Flex set to join the S&P 500 on June 22

Marvell and Flex are slated to be added to the S&P 500 on June 22. The change can prompt forced buying by passive funds that track the index, creating a short-term concentration of demand. Marvell’s positioning in custom AI chips and Flex’s role in AI hardware manufacturing are also drawing attention. Both stocks are expected to benefit from incremental inflows tied to index inclusion.
