The 13F filing, required by the SEC for institutional investment managers with over $100 million in US equity holdings, discloses their quarterly positions.
Historically, AIMCo held a small stake in MSTR between late 2019 and mid-2020, comprising around 198,000 shares. The fund exited this position in September 2020, shortly after CEO Michael Saylor shifted the company's focus towards Bitcoin as a corporate treasury asset in August 2020. In some jurisdictions, institutional investors face restrictions on directly holding Bitcoin, prompting them to explore alternative exposure through investments like Strategy or BlackRock's IBIT.
