Institutional investors adjust semiconductor holdings

Form 13F filings released on 31 July 2026 show U.S. institutional investors reshuffling positions in two leading chip makers. Groupama Asset Management cut its stake in Advanced Micro Devices by 37%, selling 11,109 shares and ending the quarter with roughly $3.9 million of AMD stock, while Axiom Investment Management opened a new position of 1,238 AMD shares worth about $0.25 million. In the same filing period, Groupama also trimmed its Broadcom holding by 1.4% to 854,556 shares (about $264.5 million), whereas Summitry LLC more than doubled its Broadcom stake, adding 167 % to hold 19,559 shares valued at roughly $6.0 million. The moves illustrate divergent strategies among investors—some reducing exposure to semiconductor firms, others increasing it—within the broader context of portfolio adjustments during the first quarter of 2026.
