Sen. Alan Armstrong (R-OK) reported that they bought Berkshire Hathaway Inc (BRK-B) stock worth $50K–$100K on March 27, 2026. The trade was disclosed in a Periodic Transaction Report filed on July 21, 2026, 116 days after the trade.
That is later than the STOCK Act allows: members must report a trade within 45 days of learning of it. Late reports usually carry a $200 fee.
Across all their reports we have read, Alan Armstrong disclosed 370 stock trades.
The law gives only a range for each trade, so the exact amount and price are not public.
What happened next: BRK-B rose 6% from the week of the purchase to our latest weekly price (still held, as far as the reports show), while the S&P 500 moved +17.4%. This is the stock's move, not the member's profit.

Examples
In 2020 several senators faced questions over stock sales made after private briefings on the coronavirus. Those trades became public through the same kind of report this story is built from.

Members of Congress write the rules for many companies, so the law makes them tell the public when they buy or sell stocks. This report is like a referee saying which team's merchandise they bought: it does not mean they did anything wrong, but it lets everyone check.
