Amundi 13F: Adds $265M to Costco Wholesale (COST) Stake

Amundi Expands Costco Holdings

Institutional investor Amundi lifted its stake in Costco Wholesale Corporation COST by 283,360 shares during the period, according to a Form 13F filing with the Securities and Exchange Commission. The purchase brought the firm's total ownership to 2,839,016 shares. That block of stock carried an estimated value of about $2.66 billion at the close of the reporting window. Because 13F filings look backward at past quarters, this snapshot captures portfolio choices made earlier and may not reflect current holdings.

Inside Amundi's Portfolio Strategy

This addition follows a pattern of active portfolio adjustments by Amundi across various sectors this year. The large asset manager recently made several notable moves, including trimming positions in Chubb Limited and CSX Corporation while expanding stakes in companies like Cummins Inc., CME Group Inc., and American Water Works. Adding to its membership warehouse investment shows the firm continues to seek exposure among large consumer defensive operators.
