S&P Shake-Up: Marvell Technology & Flex to Join the S&P 500

Change is coming for one of the most watched large-cap indexes on the market. Recently, S&P Global announced its quarterly rebalances for the S&P 500, S&P MidCap 400, and S&P SmallCap 600. Effective June 22, 2026, Marvell Technology and Flex will be joining the S&P 500. These two companies will be replacing Pool Corp and Cambell’s.  Based in Santa Clara, California, Marvell Technology produces semiconductors employed in the AI buildout. With a market cap of roughly $230 billion, the company was recently showcased by Nvidia CEO Jensen Huang, who proclaimed Marvell is set to become the “next trillion-dollar company”.

Through the flexibility of the ETF wrapper, there are plenty of different ways for advisors and investors to play into this development.  For instance, one could look to dial into the change by investing in the State Street Technology Select Sector SPDR ETF (XLK A). XLK provides low-cost exposure to the tech sector of the S&P 500, which both Marvell Technology and Flex are slated to be joining later this month. This strategy could pay off for those that are optimistic about not only the tech sector, but also the opportunities within these new companies.  See More: Apple’s WWDC 2026 Creates Buy Opportunity for XLK Alternatively, investors may opt to give the Invesco S&P 500 Equal Weight ETF (RSP B+) a shot instead. True to its name, RSP aims to hold access to its S&P 500 securities with approximately equal portfolio weightings. This lets the fund work as a means to play the index as a broad theme, without being as beholden to the performance of any of its individual securities.  XLK and RSP are just two of many compelling funds that offer a means to tap into a newly rebalanced S&P 500. As such, those looking to add a new fund to their portfolio should always perform their due diligence and research before choosing to pull the trigger.  For more news, information, and analysis, visit the Equity ETF Content Hub.
