CapitolRadar analysis
2 disclosed BRK-A trades split evenly between buys and sells
2 tracked trades in Berkshire Hathaway Inc. (BRK-A) were disclosed for the period from September 2 through September 24, 2026. The activity consisted of 1 buy and 1 sell by 2 distinct traders. Both transactions fall within 2026 Q3, giving the quarter 2 tracked trades and a buy count of 1.
This is a very small sample. The equal split between buying and selling describes only these two disclosures and does not establish a broader direction in congressional or insider sentiment. The provided data does not identify the seller or include transaction values, so the analysis cannot compare the relative size of the buy and sell.
1 buyer: Ro Khanna, with the latest buy on September 2
1 named buyer appears in the tracked BRK-A activity: Ro Khanna. He recorded 1 buy, dated September 2, 2026. Because there is only one buyer and one purchase in the sample, there is no repeated buying pattern or multi-buyer concentration to evaluate.
The buyer cohort also bought 6 other listed securities: Arch Capital Group (ACGL), American Tower (AMT), Biogen (BIIB), Cadence Design Systems (CDNS), Costco Wholesale (COST), and D.R. Horton (DHI). For each ticker, 1 of the BRK-A buyers also bought the security. Since the BRK-A buyer group contains only one person, these overlaps reflect a single buyer’s disclosed activity rather than a broad shared pattern.
45-day reporting lag limits timing conclusions
Congressional disclosures can be reported up to 45 days after a transaction, so publication timing may differ materially from the trade date. Disclosed transaction amounts are generally reported as ranges, making dollar-value figures estimates rather than exact amounts; no amount ranges were provided here. Those limitations, together with the two-trade sample, constrain conclusions about timing, scale, or conviction.
