Marvell Technology and Flex to join S&P 500 index, replacing Pool and Campbell's

June 6, 2026 - 03:30

The S&P 500 index is getting a tech-heavy shakeup. Marvell Technology, a semiconductor and infrastructure chipmaker, along with Flex, a global electronics manufacturing services provider, are set to be added to the benchmark index. They will replace Pool Corporation, the swimming pool equipment distributor, and Campbell's Company, the iconic soup and snack maker.

The changes reflect a broader shift in the U.S. economy. While Pool and Campbell's represent stable, consumer-facing industries, their removal signals that the market's center of gravity is moving toward high-growth technology and manufacturing. Marvell, known for its data infrastructure chips used in cloud computing and 5G networks, has seen its valuation climb as demand for artificial intelligence hardware surges. Flex, which designs and builds electronics for major brands, benefits from the ongoing reshoring of supply chains and the complexity of modern device production.

The index changes are driven by market capitalization thresholds. Companies that fall below the required size or see their stock value decline are often swapped out for rising firms. For investors, the addition of Marvell and Flex means the S&P 500 will have a slightly heavier tilt toward the tech sector, which already dominates the index's performance. The moves are expected to take effect before the market opens on the scheduled rebalancing date.
