CapitolRadar analysis
48 trades skewed toward purchases
BRK-B has 48 tracked trades from 2019-09-04 through 2026-08-07: 36 buys and 12 sells across nine distinct traders. Purchases therefore represent 75% of the activity, versus 25% for sales. The record is buy-heavy, but nine traders remain a small sample and the trade count does not indicate how much capital was committed.
The strongest listed quarter was 2024 Q4, with nine trades, all buys. That followed three buys in 2024 Q3. Activity remained purchase-oriented through 2025: Q1 had three trades and two buys, Q2 had five trades and three buys, Q3 had five trades and five buys, and Q4 had four trades and three buys. The 2026 observations are much thinner: Q2 contains one sale, while Q3 contains one buy. Those single-trade quarters are too small to establish a broader change in behavior.
28 of 36 buys came from three traders
Ro Khanna recorded 12 buys, most recently on 2025-10-30; Marjorie Taylor Greene recorded 10, most recently on 2025-10-24; and Josh Gottheimer recorded six, most recently on 2025-01-16. Together, they account for 28 of the 36 buys, or about 78%.
The other disclosed buyers were Jared Moskowitz with three, Markwayne Mullin with two, and Maria Elvira Salazar, Rich McCormick and Tommy Tuberville with one each. Collectively, the eight named buyers account for all 36 tracked purchases.
Limited overlap with other disclosed purchases
Three of these buyers also bought META, and three also bought MSFT. Two also bought each of SPCX, GLW, AMD and MRK. These overlaps involve only two or three people apiece, so they should be read as small-sample associations rather than broad patterns.
Disclosure timing is an important limitation: filings can appear up to 45 days after a transaction, so the data may lag actual trading. Disclosed transaction amounts are generally reported in ranges, making value estimates approximate; no transaction-value figures are provided here.
