Key Points

Although Form 13F filings allow investors to track which stocks Wall Street’s savviest money managers are buying and selling, Buffett’s favorite stock won’t show up in Berkshire’s quarterly 13Fs.
Abel piled $4.53 billion into the stock nearest and dearest to Buffett’s heart in the second quarter, and its valuation remained attractive throughout the third quarter.
For the first time in more than half a century, Berkshire Hathaway (NYSE:BRKA)(NYSE:BRKB) entered the year in uncharted territory. Its longtime CEO, Warren Buffett, retired on Dec. 31, giving control of the company's day-to-day operations and its $356 billion portfolio to successor Greg Abel.
Abel wasted little time making his mark. During the first quarter, he sent 16 stocks packing and reduced Berkshire's stakes in six others. He also piled into Google parent Alphabet (NASDAQ:GOOGL)(NASDAQ:GOOG), which has become Berkshire's No. 3 holding.

Before mid-July 2018, Buffett and his now-late right-hand man, Charlie Munger, could only repurchase their company's stock if it fell to or below 120% of book value (as of the most recent quarter). Given that Berkshire never dropped to this line in the sand, not a dime was spent on buybacks.
On July 17, 2018, Berkshire's board amended its buyback program to allow its investing superstars to get off the proverbial bench. As long as Berkshire had at least $30 billion in combined cash, cash equivalents, and U.S. Treasuries on its balance sheet, and the Oracle of Omaha viewed shares as intrinsically cheap, buybacks could continue without an end date or ceiling.
Buffett repurchased shares for 24 consecutive quarters after these covenants were amended. Meanwhile, his successor, Greg Abel, spent $234 million buying back Berkshire's stock in the first quarter and an additional $4.53 billion during the second quarter. Collectively, Abel and Buffett have deployed around $82 billion for buybacks since mid-July 2018.
Over the last eight years, capital has always been available for share repurchases. The only wildcard has been whether Berkshire Hathaway's stock was attractively valued.
BRK.A Price to Book Value data by YCharts.
For a 21-month period (June 2024-February 2026), Berkshire's stock spent most of its time at a 60% or greater premium to book value. Unsurprisingly, not one penny was spent on buybacks during this time frame.
However, a sub-50% premium to book value has historically been a green light for share repurchases. Given that Berkshire Hathaway spent almost the entirety of the third quarter oscillating between a 40% and 50% premium to book, the odds are good that Abel deployed billions on buybacks of Warren Buffett's favorite stock in the September-ended quarter.
