Berkshire Hathaway Successor Greg Abel: Company Investment Managers Operate Their Own Stock Portfolios Independently, Never Interfere
Berkshire Hathaway successor Greg Abel stated in a 2023 interview that the company's investment managers operate their own stock portfolios independently. He only observes and learns, occasionally asking, "What triggered your interest?" but does not interfere, emphasizing, "That is their portfolio, and it always will be."
Abel mentioned that he is not very aware of who is buying or selling what in the two managers' portfolios, as his main purpose of observation is to learn about their stock selection triggers, not to approve or change anything. The two managers do not overlap or report trading details to him, and he clearly defines the boundaries of their portfolios as "their territory."
Todd Combs subsequently left Berkshire in December 2025 to join JPMorgan, where he became the head of a new $10 billion strategic investment group under the bank's safety and resilience initiative and served as a special advisor to Jamie Dimon; his former position as CEO of Geico was taken over by COO Nancy Pierce. Ted Weschler remains in his position.
After Abel took over as CEO, he stated in a shareholder letter that the ultimate responsibility for equity investments lies with him; Weschler manages about 6% of the investments, including some positions that were originally Combs', while continuing to participate in major opportunity assessments and business inputs. This led to the conclusion that about 94% of the core publicly traded stock positions are now directly overseen by Abel.
Previously, Combs and Weschler managed only about 10% of the approximately $300 billion stock portfolio, independently of Warren Buffett and each other. The market generally attributes relatively smaller holdings such as DaVita, Sirius XM, VeriSign, Amazon, Visa, and Mastercard to the two, while larger positions like Apple, American Express, and Coca-Cola are still considered part of Buffett's portfolio.
Mechanically, after Combs' departure, Abel reportedly sold off the stocks under Combs' name and is unlikely to hire another dedicated stock manager, further consolidating investment decision-making power in the CEO; Weschler retains an independent sleeve, but its scale is capped at single-digit percentages. The buyer is the long-term capital remaining in Omaha, while the seller is the cleared mid-sized positions. The event-driven nature comes from the transition rather than a market crash, with the beneficiaries being the CEO who can make direct decisions and the remaining single manager, while the original expectation of a "dual-manager relay for the entire portfolio" is under pressure.
On a personal level, Weschler is still associated with holdings in DaVita and Sirius XM, and his early track record of turning about $70,000 in a personal account into hundreds of millions is used to explain why this small sleeve is retained rather than merged into the headquarters' general ledger.

Abel is not someone who rose from a stock-picking position. He has managed from China Energy to Berkshire's non-insurance empire, focusing on acquiring entire companies, changing management, and monitoring capital expenditures, rather than daily reviewing 13Fs. Buffett stated at the 2024 shareholder meeting that if he were on the board, he would hand over capital allocation to Abel, reasoning that "understanding business means understanding stocks"; this statement effectively nullifies the "successor stock-picking" script given to Combs in 2010 and Weschler in 2012, changing it to a CEO-driven portfolio.
The flow of money thus shifts from "two former hedge fund managers' parallel sleeves" to "CEO's general ledger + one remaining manager." Combs took away not just personnel but also his operational bandwidth at Geico and a decade-long relationship with the JPMorgan board; the $10 billion direct investment position in the safety industry means sending a stock picker trained by Berkshire into the bank's proprietary equity. Abel's sale of stocks under Combs' name is a liquidation action confirming: sleeves can exist, but cannot form a second set of capital will.
Similar structures have appeared before. BlackRock has integrated active stock picking into platform rules, Bridgewater has separated research from order placement, and Buffett himself early on delegated small positions to deputies but never handed over Apple-level positions. The current industry phase is one of control during a transition: hiring star managers during expansion, and reclaiming pricing power to one person during consolidation. Weschler's retention of 6% seems more like a cultural buffer than a power equalization.
The structural judgment indicates a transfer of pricing power. The mechanism is that when the scale is too large, opportunities too few, and transition risks too high, organizations will abandon "multiple brains in parallel" in favor of "one person making decisions + a small observation sleeve." Independent managers were once used to prove that Berkshire was not a cult of personality; now they demonstrate that while personal worship can change individuals, it cannot be replaced by a committee.

Sleeves can make money, but cannot form a second will.
Understanding business being equated to understanding stocks means the end of the stock-picking position.
