It’s been a year of historic change for Berkshire Hathaway (BRKA -0.18%)(BRKB -0.19%) and its shareholders. On Dec. 31, after more than half a century at the helm, Warren Buffett retired as CEO and passed the baton to his understudy, Greg Abel.
Abel hasn’t wasted any time reshuffling Berkshire’s $357 billion investment portfolio. The company’s Form 13F filing on Aug. 14, detailing second-quarter trading activity, shows that Warren Buffett’s successor pared down Bank of America (BAC -0.61%), yet again, and absolutely piled into one of Wall Street’s most beloved virtual monopolies: Google parent Alphabet (GOOGL -2.09%)(GOOG -2.18%).

Abel pared down Bank of America stock for an eighth consecutive quarter
During the first quarter, Abel exited 16 positions and slashed six others, one of which was money-center behemoth Bank of America. Though far fewer holdings were pared down in the second quarter, BofA was once again on the list, with 30,230,150 shares sold. Buffett or Abel has sold shares of BofA in each of the last eight quarters, reducing Berkshire’s stake by a cumulative 53%.
Profit-taking is the most logical reason behind this selling, but it’s probably not the only catalyst.

For example, Bank of America stock isn’t the bargain it once was. When the Oracle of Omaha initially took a stake in BofA’s preferred stock in August 2011, its common shares were trading at a 62% discount to book value. In early August 2026, it was trading at a 62% premium to its book value. Both Buffett and Abel are sticklers for value.
Furthermore, BofA is the most interest-sensitive of America’s big banks. While this distinction was a massive tailwind when the Federal Reserve raised interest rates from March 2022 to July 2023, it became a drag on net interest income when the Fed cut rates from September 2024 to December 2025.

Alphabet has become one of Berkshire Hathaway’s core holdings
On the other hand, Berkshire’s new boss can’t stop buying shares of Alphabet. Abel more than tripled Berkshire’s stake in the company in the first quarter and added another $17 billion, including $10 billion via private placement, during the second quarter. It’s now surpassed Coca-Cola and Bank of America to become Berkshire’s third-largest holding.
Buffett, who initiated the purchases of Alphabet stock last year, and Abel both appreciate businesses with sustainable moats. According to GlobalStats, Google has maintained an 89% to 93% share of global internet search traffic over the trailing decade.
Meanwhile, YouTube, which Alphabet also owns, is the second-most-visited social site behind Google. Suffice it to say, Alphabet commands exceptional ad pricing power during long-winded economic expansions.

But it’s Alphabet’s artificial intelligence (AI) ties that likely have Buffett and Abel excited. Since integrating generative AI and large language model capabilities into Google Cloud, the world’s third-largest cloud infrastructure services platform by total spend, sales have skyrocketed. This segment, which generates substantially juicier margins than advertising, delivered 82% year-over-year sales growth in the June-ended quarter.
If Alphabet’s AI ambitions are realized, it’s not out of the question that it eventually unseats Apple as Berkshire Hathaway’s top holding.
