A Major Sell-Off by Buffett’s Successor? A Potential Turning Point for Berkshire’s Investment Philosophy

Berkshire Hathaway's First 13F Under Greg Abel: Key Moves to Watch
Published on: Jan 21, 2026

As the legendary Warren Buffett era gradually gives way to a new chapter, a move that could redefine the company’s core investment philosophy appears to be quietly taking shape. Barely a month after Greg Abel, Buffett’s hand-picked successor, took over as CEO of Berkshire Hathaway (BRK.A), a regulatory filing has sent ripples through the market: Berkshire may be looking to sell its entire stake in Kraft Heinz (KHC).

Could this be the first major signal of a shift in the “post-Buffett” era?

An Unusual Warning

On Tuesday, the food giant Kraft Heinz embedded an unusual risk alert within a routine filing submitted to the U.S. Securities and Exchange Commission (SEC). The filing stated that its largest shareholder, Berkshire Hathaway, “may offer to sell, from time to time” all of its 325,442,152 shares of common stock.

While Berkshire has not commented and no sales have been executed yet, this proactive disclosure was enough to jolt the market. Following the news, Kraft Heinz shares fell nearly 4% to close at $22.85. The market sensed something different: the famed Berkshire, known under Buffett for its “near-permanent” holdings of core assets, might be preparing to sell.

Kraft Heinz itself represents a storied, yet somewhat regretful, chapter in Buffett’s investment history. The merger of H.J. Heinz and Kraft Foods in 2015, orchestrated by Buffett and private equity firm 3G Capital, created the world’s fifth-largest food and beverage empire. At the time, Buffett firmly believed in the formidable “economic moat” surrounding these household brands.

Reality, however, delivered a heavy blow. Post-merger, the company’s stock plummeted more than 70% from its highs. In 2019, Kraft Heinz recorded a staggering $15 billion goodwill impairment charge, with Berkshire absorbing roughly $3 billion of that loss. Last summer, Berkshire took another $3.76 billion writedown on its Kraft Heinz investment.

Abel’s First Major Move?

Now, with Greg Abel officially taking the CEO reins on January 1st, the winds may be shifting. Although Buffett remains Chairman, all eyes are on Abel to see how he will write his own chapter.

CFRA Research analyst Cathy Seifert commented: “My sense is that Greg Abel’s leadership style may be a departure from Buffett’s, and this sale, if completed, would represent a shift in corporate mindset.” She further analyzed, “Berkshire under Buffett typically only made acquisitions—not divestitures. It’s not inconceivable, in our view, that Abel may likely assess every Berkshire subsidiary and decide to jettison those that do not meet his internal hurdles.”

Market observers view a potential Kraft Heinz sale as the most obvious “low-hanging fruit.” Chris Ballard, Managing Director at Check Capital, stated plainly: “Selling Kraft is probably the most low-hanging fruit for Greg. We personally wouldn’t be sad to see the holding go.”

The Post-Buffett Era: A Balancing Act Between Change and Continuity

If the divestment materializes, its significance would extend far beyond simply offloading an underperforming investment. It could signal a subtle recalibration of the governance logic at the vast Berkshire empire:

  1. From “Collector” to “Portfolio Manager”: The Buffett era resembled that of a patient “asset collector,” prioritizing franchise value and long-term compounding. Abel, known for his operational prowess, may lean more towards proactive and dynamic portfolio management, applying stricter standards for return on capital and growth potential to Berkshire’s eclectic mix of businesses.
  2. A New Path for the Cash Pile: Berkshire currently sits on a record cash hoard of $381.7 billion. Asset sales would further bolster its “war chest.” How will this colossal sum be deployed? Will it fuel another “elephant-sized” acquisition, or could it lead, as some investors hope, to Berkshire’s first-ever cash dividend? This is a core question facing Abel.
  3. Redefining the “Moat”: The Kraft Heinz case highlights how traditional brand moats can erode in a fast-changing world. Abel’s future criteria for investing in consumer brands may incorporate a more acute awareness of shifting consumer trends.

Of course, any transition will not be radical. Abel has overseen all of Berkshire’s non-insurance operations since 2018 and knows the company intimately. Buffett has also bestowed his unreserved trust upon his successor, praising him in his Thanksgiving note to shareholders: “Greg has more than met the high expectations I had for him… I can’t think of… anyone that I would select over Greg to handle your savings and mine.”

Conclusion

For investors, a symbolically significant “farewell” may be heralding the start of a new era. Selling Kraft Heinz is not merely about disposing of a past investment; it could be a declaration to the market that Berkshire Hathaway, while holding true to its value-centric core, is engaging in necessary “portfolio metabolism” to adapt to a new economic environment and leadership style.

Buffett’s legend is now eternal, while Abel’s chapter begins with this suspenseful comma. The market watches with bated breath to see how the new captain will steer this trillion-dollar ship, navigating between inheritance and transformation to chart a course for the “post-Buffett” age.
