On June 22, Flex Ltd. rose 3.31% in regular trading, trading at $149.96/share, with turnover of $76.51 million. The stock surged as its formal inclusion in the S&P 500 index took effect before the market open, triggering concentrated buying from passive funds and mandate-constrained active managers.

S&P Dow Jones Indices previously announced that Flex would officially join the S&P 500 on June 22, replacing Pool Corp. The effective date triggered a wave of mandatory allocation from index-tracking ETFs and institutional funds with investment universe restrictions tied to the benchmark. Additionally, the company's planned spin-off of its Cloud and Power Infrastructure (CPI) business into a standalone publicly traded entity continued to provide supplementary support for the share price.

Notably, Flex's strength stands in contrast to the broader Electronic Manufacturing Services sector, where peers including Celestica (-2.51%), TE Connectivity (-1.71%), Jabil Circuit (-1.54%), TTM Technologies (-0.41%), and Fabrinet (-0.39%) all traded lower during the session.
