Frequently asked questions about BRK-B activity

  • Which institutional owners are buying BRK-B?

    Institutional owners buying BRK-B include investors who have either initiated new positions or increased their existing holdings based on recent SEC 13F filings. The activity table above highlights which funds added shares in the latest reporting periods and how their positions changed over time.

  • What does "buy" mean in BRK-B activity?

    "Buy" means an investor increased their reported position in BRK-B compared to the prior reporting period. This reflects growing exposure to BERKSHIRE HATHAWAY INC-CL B (BRK-B) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
