Amundi, a major European asset manager, substantially raised its holdings in MicroStrategy (MSTR) during the third quarter, reaching nearly 1.9 million shares. This move signals continued institutional interest in bitcoin proxies, despite MSTR's stock and the underlying cryptocurrency experiencing an 18% slide since the quarter's end.
Imagine a big company called MicroStrategy that buys lots of special digital coins called Bitcoin, like collecting rare stamps. A very big money manager in Europe, Amundi, decided to buy many more shares of MicroStrategy, even though MicroStrategy's shares and the digital coins themselves had recently gone down in value. It's like a grown-up deciding to buy more shares in a toy company, even if the toys aren't selling as well right now, because they believe the toys will be popular again later.
Analysis
Amundi, Europe's largest asset manager, significantly increased its investment in MicroStrategy (MSTR) during the third quarter of the year. A Form 13F filing on November 6 revealed that the Paris-based firm boosted its MSTR stake by approximately 44%, acquiring an additional 579,672 shares to reach a total of 1,903,725 shares. This holding was valued at $291.4 million as of September 30, marking a substantial increase from the $115.1 million valuation of its smaller stake at June 30. This aggressive accumulation by Amundi, which manages €2.579 trillion in assets, occurred even as MSTR shares began to slide, indicating a strategic long-term view on the company's bitcoin-centric approach.
Amundi
Amundi's decision to nearly double the dollar value of its MicroStrategy position, from $115.1 million to $291.4 million, reflects a notable commitment to gaining exposure to the cryptocurrency market through public equities. The firm's 13F filing, which combines holdings from 17 different managers within its group, suggests a diversified approach to this investment, encompassing client, fund, and discretionary positions. This substantial increase in MSTR shares by such a prominent European asset manager provides a strong signal of institutional appetite for digital asset proxies, even if the immediate market performance of MSTR stock has been challenging.
MicroStrategy
MicroStrategy itself continued its strategy of accumulating Bitcoin, purchasing another 1,036 BTC for $81.9 million at an average price of $79,012 last week. This brought its total treasury to 850,364 BTC, acquired for $64.16 billion at an average cost of $75,456. The company's average acquisition cost now exceeds the spot Bitcoin price, placing its substantial holdings underwater on paper. MSTR funds these Bitcoin purchases primarily by selling new common stock through an at-the-market program, creating a feedback loop where a weaker share price necessitates greater dilution for each Bitcoin acquired. This dynamic is crucial for understanding the stock's performance and its sensitivity to Bitcoin's price movements.
Barclays
Amundi was not alone in increasing its exposure to Bitcoin proxies during the third quarter. Barclays, another major European financial institution, also filed a 13F on November 6, disclosing a 48% increase in its holdings of BlackRock's iShares Bitcoin Trust (IBIT). Barclays' stake in IBIT reached 3,942,900 shares, valued at $186.7 million as of September 30. Similar to Amundi's filing, this represents a combination of client, managed, and trading book positions rather than direct proprietary capital. These two filings collectively illustrate a broader trend among traditional European managers to enhance their exposure to Bitcoin-related investments, even as the spot market experienced a cooling period towards the end of the quarter.
Key points
- Amundi, Europe's largest asset manager, increased its MicroStrategy (MSTR) stake by 44% in Q3, reaching $291.4 million.
- The investment boost occurred despite an 18% drop in MSTR shares and a slide in Bitcoin prices since September 30.
- MicroStrategy continued its Bitcoin accumulation, acquiring 1,036 BTC for $81.9 million, bringing its total to 850,364 BTC.
- MSTR's average Bitcoin acquisition cost of $75,456 now exceeds the spot price, leaving its holdings underwater.
- Barclays also increased its stake in BlackRock's iShares Bitcoin Trust (IBIT) by 48% in the same quarter, signaling broader institutional interest.
The significant increase in Amundi's MSTR stake, alongside other institutional investments like Barclays' IBIT holdings, suggests a growing long-term conviction among major financial players in the value of Bitcoin and its proxies. This sustained institutional interest could provide a floor for MSTR's stock and Bitcoin's price, potentially leading to a rebound as market conditions improve.
Despite institutional buying, MSTR shares have slid significantly, and its Bitcoin holdings are currently underwater on paper, indicating immediate market headwinds. The company's strategy of funding Bitcoin purchases through stock sales could lead to further dilution if share prices remain weak, creating a challenging feedback loop for investors.
