  • 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).
