Marvell Technology, a key player in the burgeoning artificial intelligence infrastructure market, is slated to join the prestigious S&P 500 index on June 22. This move marks the latest significant addition of a semiconductor company to the benchmark index.
Flex, a prominent contract manufacturer specializing in electronics, will also be integrated into the S&P 500 on the same date. According to a recent press release, these two companies will succeed Pool Corp and The Campbell's Company in the index.

Marvell Technology's stock saw a 5% surge in extended trading following the announcement. The chipmaker received a significant boost earlier in the week when Nvidia CEO Jensen Huang alluded to its potential as the "next trillion-dollar company" during discussions about their strategic partnership. Nvidia has also made a substantial investment of $2 billion into Marvell.
Flex also experienced a 4% increase in its stock price during extended trading. The company is renowned for providing manufacturing services to leading technology giants, including Apple and Nvidia.
This significant index rebalancing underscores the increasing dominance and importance of the technology sector within the broader stock market landscape. Other technology firms such as Veeva Systems, AppLovin, Datadog, DoorDash, and Robinhood have also been incorporated into the S&P 500 in recent years, reflecting ongoing trends.
Marvell, established in 1995 and headquartered in Santa Clara, California, initially focused on producing components for spinning disk drives. Flex, formerly known as Flextronics, maintains its headquarters in Singapore while operating manufacturing facilities across both the U.S. and Asia.
