On September 16, Marvell Technology rose 3.31% in regular trading, trading at approximately $228.98 per share, with turnover of $3.28 billion. The rebound comes as the effective date for the company's inclusion in the S&P 500 Index draws near.

S&P Dow Jones Indices previously announced that Marvell Technology will be officially added to the S&P 500 Index before the market opens on September 21. As the effective date approaches, mandatory allocation requirements from passive index-tracking funds are providing incremental buying support. Meanwhile, Bank of America maintained its Buy rating on the stock, citing strong prospects in custom chip and XPU accessory businesses, projecting related revenue could reach $30 billion by the end of the decade.

The broader optical communications and semiconductor sectors also saw a pre-market rebound on September 16, with Coherent up 2.52%, Applied Optoelectronics up 2.34%, and Corning up 1.71%. The bounce follows a sharp sell-off on September 14, when Marvell dropped over 8% after the FCC finalized supply chain security rules, triggering a sector-wide profit-taking event. The current move partly reflects an oversold technical recovery.
