As 2025 draws to a close, the investment world is witnessing a historic moment: 95-year-old Warren Buffett is formally stepping down as CEO of Berkshire Hathaway (BRK.A) (BRK.B). In his farewell letter in November, the “Oracle of Omaha” announced he would “go quiet,” no longer writing the annual shareholder letters or speaking at the annual shareholders’ meeting. The retirement of this iconic figure inevitably leads investors to ask: Is Berkshire Hathaway stock still worth holding in the post-Buffett era?
In his farewell letter, Buffett clearly stated that he would retain a significant portion of Berkshire’s Class A shares until shareholders are confident in his successor, Greg Abel. This declaration undoubtedly injects a dose of confidence into the market. More importantly, Abel has worked closely with Buffett for nearly two decades and has publicly stated that he does not intend to materially alter the company’s investment philosophy or capital allocation strategy.
In fact, Buffett leaves behind an enviable foundation for Berkshire’s new management:
Record Cash Reserves: As of the third quarter of 2025, the company’s cash reserves reached $381 billion, providing Abel with significant strategic flexibility. He has the capacity to pursue large-scale acquisitions (surpassing Buffett’s 2016 acquisition of Precision Castparts for $37 billion), increase investments in the portfolio, or even consider initiating dividend payments or regular share buybacks.
Robust and Diversified Business Portfolio: From GEICO to BNSF Railway, from See’s Candies to Duracell, Berkshire’s operating companies form a solid earnings base. Most of these businesses hold leading market positions and generate stable cash flow.
High-Quality, Balanced Investment Portfolio: Heavy investments in Apple and newer positions like Alphabet show that while maintaining its value-investing core, Berkshire is gradually embracing technological innovation. This may signal a more active participation in technology sector investments during the Abel era.
In the post-Buffett era, the drivers of Berkshire’s stock price will undergo subtle changes. Firstly, the massive cash hoard is both an advantage and a challenge. If Abel can deploy it effectively, potentially to a higher standard than Buffett, it could drive company value. Analysts at Morgan Stanley noted that the market will closely watch Abel’s first major acquisition, which will be a key test of his capital allocation skills. Secondly, Buffett’s vision that Berkshire should need “only 5-6 CEOs over the next century” reflects the company’s extreme focus on management stability. This long-term oriented corporate culture is a key trait that distinguishes Berkshire from other publicly traded companies.
As Buffett himself stated, Berkshire has “less chance of a devastating disaster” than any other business he can think of. This stability during times of crisis is particularly valuable in today’s environment of AI fervor, rampant cryptocurrency speculation, and relatively lax financial regulation.
In summary, Berkshire Hathaway still possesses significant investment value in the post-Buffett era: The company’s financial strength, business diversity, and management continuity make it a rare “safe haven” asset in an uncertain market environment. Although short-term volatility may occur due to the leadership transition, the solid fundamentals and Abel’s strong motivation to prove himself provide long-term investors with sufficient margin of safety.
As Buffett hinted in his farewell letter, the “magic ingredient” of Omaha might exist not just in the water, but is deeply rooted in Berkshire’s corporate culture. For investors who can withstand normal market fluctuations and seek long-term, steady returns, Berkshire stock remains a core asset worth holding in an investment portfolio. The curtain is just rising on a new era, and the Berkshire investment legend is far from over.
