Europe's top asset manager Amundi lifts MSTR holding 44% to $291M

Amundi, the largest asset manager in Europe, increased its position in Strategy (MSTR) by roughly 44% during the third quarter, according to a Form 13F submitted Nov. 6. The filing shows the stake reached 1,903,725 shares, valued at $291.4 million based on Sept. 30 prices.

That represents an increase of 579,672 shares from the 1,324,053 shares Amundi disclosed at June 30, when the holding was worth approximately $115.1 million. The Paris-based firm, which managed €2.579 trillion in assets as of September's end — an 11% year-over-year rise — has described itself as Europe's leading asset manager.

The filing comes as MSTR has surrendered much of its third-quarter gains. Strategy shares ended Sept. 30 at $153.09 and were near $126 on Monday, an 18% decline that would value Amundi's reported stake at roughly $239 million at Monday's close, according to Yahoo Finance data.

A 13F filing serves as a snapshot, not a trading record. Amundi submitted a combined report incorporating 17 other managers within its group, meaning the Strategy line may encompass client, fund and discretionary positions rather than a single proprietary bet, and the firm may have adjusted the holding since Sept. 30.

Strategy continues purchases amid stock decline

Strategy itself kept accumulating. The company acquired another 1,036 bitcoin last week for $81.9 million at an average price of $79,012, as shown in a Monday 8-K filing and company release, bringing its treasury to 850,364 BTC purchased for $64.16 billion at an average of $75,456.

That average cost now exceeds the spot bitcoin price, leaving the holdings underwater on paper even after the firm added 811 bitcoin the previous week. Strategy's public ledger still ranks it as the largest corporate bitcoin holder, with the holdings representing roughly 4% of bitcoin's 21 million supply cap.

MSTR roughly doubled during the third quarter itself. The June 30 13F valued Amundi's then-smaller stake at an implied $86.93 per share, compared to the $153.09 Sept. 30 close, meaning the dollar value of the position grew faster than the share count. Since then, the stock has mirrored bitcoin's decline into the mid-$70,000s, erasing a significant portion of that mark-to-market gain for anyone still holding the Sept. 30 position.

The timing matters because Strategy finances most of its bitcoin purchases by issuing new MSTR common shares through an at-the-market program. A lower share price increases dilution for each coin acquired, creating the feedback loop that has characterized the stock's moves this year.

Banks increased bitcoin proxy holdings in same period

Amundi was not the only large European institution adding bitcoin exposure during the quarter. Barclays' own 13F, also filed Nov. 6, shows 3,942,900 shares of BlackRock's iShares Bitcoin Trust (IBIT) worth $186.7 million at Sept. 30, up 48% from 2,658,147 shares three months earlier, according to SEC records.

That Barclays line carries the same caveat: a 13F includes client, managed and trading book positions, not proof the bank deployed its own capital into bitcoin. Still, the two filings together paint the same picture for Q3: traditional European managers kept increasing exposure to bitcoin proxies even as the spot market cooled heading into the fall.

The institutional additions contrast with a weaker tape since quarter-end. Bitcoin has fallen into the mid-$70,000s, Strategy stock has followed it lower, and the value of Amundi's disclosed MSTR stake has contracted even as the share count on the filing remained constant. At Monday's close, the disclosed stake was roughly $52 million below its Sept. 30 mark.

Whether Amundi continued buying, reduced its position, or simply held through October's decline will not be known until the next 13F. For now, the Nov. 6 filing stands as the record from Europe's largest asset manager: nearly 1.9 million Strategy shares, up 44%, at a $291 million quarter-end valuation.
