Warren Buffett is no longer running Berkshire Hathaway, and the so-called "Buffett premium" has evaporated. But at least one U.S. senator isn't running for the exits.

Sen. Jerry Moran (R-Kan.) recently disclosed buying between $15,000 and $50,000 worth of Berkshire Hathaway (BRK-B) B shares on June 23, according to data from Quiver Quantitative. The purchase is part of a pattern: Moran has been steadily accumulating the stock throughout 2026, with multiple buys in May and earlier years.

Moran also bought Alphabet (GOOG) stock worth $1,000 to $15,000 on the same day. Those two stocks — Berkshire and Alphabet — are the only ones he has traded this year.

Here's a look at Moran's Berkshire purchases in 2026 alone:

• May 27: Bought $1,000 to $15,000 (four separate transactions)
• June 23: Bought $15,000 to $50,000

The senator has a history of buying and selling large-cap stocks, and his recent moves suggest he's willing to bet on Berkshire's future under new CEO Greg Abel, even as many of his colleagues head for the exits.

The Great Congressional Sell-Off

Berkshire Hathaway long enjoyed a premium valuation thanks to Buffett's legendary track record. Investors were willing to pay more for the conglomerate's assets, expecting continued outperformance. But with Buffett gone, that premium has vanished. The stock is down 1.6% year-to-date, while the SPDR S&P 500 ETF (SPY) is up 11.5%.

Retail investors aren't the only ones losing faith. Several members of Congress have sold Berkshire shares in 2026:

• Rep. Josh Gottheimer (D-N.J.) sold $1,000 to $15,000 in two transactions on May 4.
• Sen. Tina Smith (D-Minn.) sold $100,000 to $250,000 on March 31 and another $100,000 to $250,000 on Jan. 27.
• Rep. Gil Cisneros (D-Calif.) sold $1,000 to $15,000 on March 25.
• Rep. Mark Alford (R-Texas) sold $1,000 to $15,000 on March 16.
• Rep. Christian Menefee (D-Texas) sold shares on Feb. 10 in transactions totaling $1,000 to $15,000, $15,000 to $50,000, and $15,000 to $50,000.

On the other side, Sen. Alan Armstrong (R-Okla.) has also been buying, not selling. He purchased $50,000 to $100,000 in Berkshire shares on March 27.

So far, the sellers have been right: Berkshire is trailing the market. But Moran and Armstrong are betting that the post-Buffett era will eventually reward patient shareholders. Time will tell which members of Congress come out on top.
