Buffett Still Runs the Book While Abel Runs Berkshire

Berkshire Hathaway's equity portfolio decisions appear to be made by Warren Buffett and portfolio manager Ted Weschler rather than new chief executive Greg Abel, with the Class B shares closing at 495.82 on Aug. 21, 2026, down 0.21% on the day.

Greg Abel has the title. Warren Buffett, it appears, still has the stock portfolio.

That is the picture emerging from Berkshire Hathaway's equity book under its new chief executive, according to reporting from CNBC. Abel, who took over as CEO, appears to be leaving the buying and selling of Berkshire's listed holdings entirely to Buffett and portfolio manager Ted Weschler. The operating conglomerate has a new boss. The investment portfolio, so far, does not.

Berkshire's Class B shares (BRK.B) last traded at 495.82, down 0.21%, in the session ended Aug. 21, 2026, against a prior close of 496.86 and a day range of 495.68 to 501.00. The Class A shares (BRK.A) closed at 743,500.00, off 0.15% from 744,600.00, with a day range of 743,500.00 to 750,265.19. Both classes finished at or near the low end of the day's range while the broad market went the other way: the S&P 500 tracker closed at $765.72, up 0.41%, the Nasdaq 100 proxy at $713.44, up 0.35%, and the Dow tracker at $532.22, up 0.89%.

A split job, not a handover

Berkshire has always been two companies bolted together. One is an operating business — railroads, utilities, insurance underwriting, manufacturing, retail — that throws off cash. The other is a portfolio of listed equities funded largely by that cash and by insurance float, the premiums held before claims are paid.

Abel's career was built on the first of those. He ran Berkshire Hathaway Energy and, latterly, the non-insurance operating businesses. Nothing in that record makes him a public-markets stock picker, and the succession plan has long been understood to separate the CEO role from the investment role rather than merge them.

What the current arrangement confirms is that the separation is real and operative from day one, not something to be phased in. Buffett and Weschler are making the equity calls. Abel is not overruling them, and does not appear to be participating in them.

Why the 13F is where this gets settled

Berkshire discloses its U.S.-listed equity positions quarterly on Form 13F, the filing large institutional managers must submit to the Securities and Exchange Commission. Because the filings come with a lag and do not label who initiated a trade, Berkshire watchers have spent years reverse-engineering authorship from position size and style.

The rough convention is familiar to anyone who follows the company: very large, concentrated, long-held stakes have historically borne Buffett's fingerprints, while smaller positions have been attributed to the deputies. Weschler and Todd Combs each ran their own sleeves of capital under that structure. The reading now is that the pattern of activity still fits Buffett and Weschler, not a new hand.

That inference matters more than usual. Under a CEO who was not the portfolio's architect, the 13F becomes the clearest public evidence of who is actually deploying Berkshire's cash into equities. Investors cannot see the internal org chart. They can see the filings.

What shareholders are actually pricing

Berkshire's valuation has always embedded a question that no other large-cap carries in the same form: how much of the company is the business, and how much is the person allocating capital. A CEO transition normally settles that question. This one defers it.

The near-term implication is continuity. If the equity book is being run the way it has been run, then the discipline around price, the willingness to sit in cash and Treasury bills rather than buy something mediocre, and the concentration in a handful of large positions should all persist. Shareholders who bought Berkshire for that behavior are getting it.

The longer-term implication is that the succession risk has not been retired, only relocated. It is no longer a question about who runs the company. It is a question about who runs the portfolio after Buffett, and whether the answer is Weschler, Combs, an external hire, or a structurally different approach — more buybacks, more wholly owned acquisitions, less public-market activity.

The signals worth tracking

A few things would tell shareholders the equity mandate is genuinely moving:

• A new large position with no Buffett hallmarks. A first-time stake at a scale that only the top of the house can authorize, in a sector Buffett has historically avoided, would be the loudest signal.
• A shift in the cash-versus-equities balance. Berkshire's Treasury-bill pile has been the clearest expression of Buffett's price discipline. A sustained drawdown into equities under a different decision-maker would read differently than the same move under Buffett.
• Buyback cadence. Repurchasing Berkshire stock is a capital-allocation decision available to the CEO in a way that picking individual equities is not. Abel's imprint may show up here first.
• Acquisitions of whole businesses. This is Abel's natural territory. An operating deal would be the cleanest demonstration of where his authority actually runs.
• Language in the annual letter and at the annual meeting. Who describes which decisions, and in whose voice, has always been informative at Berkshire.

The governance read

Splitting the chief executive role from investment authority is unusual at an S&P 500 company, but it is not unprincipled. Berkshire's board effectively decided that the two jobs require different people and that trying to find one person who can do both was the wrong search.

The arrangement works cleanly while Buffett is engaged. The awkward case is a slow drift in which the CEO is accountable to shareholders for results driven substantially by a portfolio he does not control. Boards usually resolve that tension by giving the CEO the authority to match the accountability, or by ring-fencing the investment function with its own reporting line and its own named successor.

For now, the market has not treated any of this as a rupture. Berkshire's two share classes both eased modestly in the session ended Aug. 21 while the three major benchmark trackers closed higher — a small divergence, not a repricing. The company that spent decades preparing shareholders for this transition appears, at least in the portfolio, to have arranged for as little to change as possible.

Frequently asked questions

Who is making Berkshire Hathaway's stock investment decisions?

Warren Buffett and portfolio manager Ted Weschler appear to be making all of the decisions on Berkshire Hathaway's equity holdings. New chief executive Greg Abel, who took over the top job, appears to be leaving those calls entirely to them rather than directing the portfolio himself, according to reporting from CNBC published Aug. 22, 2026.

What is Greg Abel's role if he is not picking stocks?

Abel is chief executive of Berkshire Hathaway, responsible for the operating businesses — insurance, rail, utilities, manufacturing and retail — and for company-level capital allocation such as acquisitions and buybacks. His career was built running Berkshire Hathaway Energy and the non-insurance operating units, not managing a public-equity portfolio.

How did Berkshire shares perform in the latest session?

Berkshire's Class B shares closed at 495.82, down 0.21% from a prior close of 496.86, with a day range of 495.68 to 501.00. The Class A shares closed at 743,500.00, down 0.15% from 744,600.00. Both figures are as of the last trade on Aug. 21, 2026, at 20:00 GMT.

What is a 13F filing and why does it matter here?

A Form 13F is the quarterly disclosure large institutional managers must file with the Securities and Exchange Commission listing their U.S.-listed equity positions. It arrives with a lag and does not identify who initiated each trade, so Berkshire watchers infer authorship from position size and style — making it the main public evidence of who is deploying the company's cash.

Does this arrangement mean succession is unresolved?

The chief executive succession is resolved: Abel holds the job. What remains open is who will run the equity portfolio after Buffett. The current split keeps the investment function with Buffett and Weschler, which preserves continuity in the near term but defers rather than settles the question of long-run portfolio leadership.

What should investors watch next?

Key signals include a large new equity position with no Buffett hallmarks, a meaningful shift between cash holdings and equities, the pace of Berkshire share buybacks, any acquisition of a whole operating business, and the language used in the annual letter and at the annual meeting about who made which decisions.
