Warren Buffett officially handed the chief executive role at Berkshire Hathaway Inc (NYSE:BRK.A), the $1 trillion financial conglomerate he spent six decades building, to Greg Abel on January 1 this year.
He is still going into the office every day.
In an interview with CNBC this week, the 95-year-old investor said he continues to make investment decisions for Berkshire, recently completing what he described as a "tiny" new purchase without disclosing details.
He has also authorised the purchase of $17 billion in US Treasury bills this week alone, consistent with Berkshire's strategy of holding vast reserves in short-term government debt, with the company ending 2025 holding nearly $400 billion in cash and near-cash equivalents.
The picture Buffett paints is of a man who has stepped back from the title without quite stepping back from the work, a pattern that has precedent across the upper reaches of business and public life.
Henry Kissinger, the former US secretary of state, remained active as an author, adviser, and public commentator well into his late 90s until his death in 2023 at the age of 100.
Charlie Munger, Buffett's longtime business partner at Berkshire, remained the company's vice-chairman and a regular presence at its annual shareholder meetings until he died in November 2023 at the age of 99.
Rupert Murdoch stepped down as executive chairman of News Corp and Fox Corporation in 2023 aged 92, but retained the title of chairman emeritus, suggesting a similar reluctance to fully disengage.
The pattern reflects something researchers have long observed: for many high-achieving individuals, it is intellectual engagement and the desire to stay sharp, rather than financial necessity, that keeps them working deep into old age.
Buffett's continued involvement also speaks to the distinctive nature of his discipline.
Value investing, the approach he has practised throughout his career, involves identifying companies trading below their intrinsic worth and requires patience, judgment, and a depth of business knowledge that typically accumulates over decades.
His preferred holding period is "forever," with positions in companies such as American Express and Coca-Cola held for years or decades at a time.
That kind of accumulated wisdom is hard to simply hand over.
Buffett acknowledged as much in the CNBC interview, saying Abel covers more ground in a day than he could manage in a week even at his peak, while still insisting he contributes something worth contributing.
Berkshire shares have fallen around 11% since Buffett announced his retirement in May last year, even as the S&P 500 has risen by over 13% in the same period, a market signal that the transition is being absorbed cautiously.
Whether Buffett's daily presence in the office is a reassurance or a complication for Abel is a question Berkshire's new leadership has so far declined to answer publicly.
What is not in doubt is that the Oracle of Omaha has no intention of disappearing altogether.
