Warren Buffett’s Final Quarter as CEO: Berkshire Trims Big Tech Holdings

Berkshire Hathaway trimmed its massive Apple position and sold more than three quarters of its Amazon holdings last quarter, marking Warren Buffett’s final stretch as CEO. The move underscores a significant shift in Berkshire’s tech exposure, especially given Apple’s long-standing role as one of Buffett’s largest and most profitable bets.

Apple’s stake, once valued at more than $175 billion, has been steadily reduced since late 2023. As of Tuesday’s close, Berkshire’s remaining Apple holdings were worth about $60 billion. This gradual paring reflects Buffett’s disciplined approach to portfolio management, balancing concentration risk while locking in profits from one of the most successful investments in Berkshire’s history.

Amazon’s reduction was even more dramatic, with Berkshire selling over three quarters of its position. The decision highlights Buffett’s caution toward growth-oriented tech firms, particularly as market volatility and competitive pressures weigh on valuations. For investors, the sale signals Berkshire’s preference for stability and diversification as leadership transitions beyond Buffett.

Together, these moves illustrate Buffett’s hallmark strategy of taking profits and reducing exposure to concentrated bets. While Berkshire remains a major player in tech, the trimming of Apple and Amazon underscores a broader recalibration designed to ensure resilience in a shifting market landscape.

Berkshire Hathaway, the conglomerate once led by Warren Buffett, reduced its holdings in Apple and Amazon during the final quarter of 2025. According to a regulatory filing, Berkshire sold about 10.3 million shares of Apple roughly 4% of its stake in the iPhone maker. This continues a trend that began in late 2023, though the pace of Apple sales has slowed. Apple, once Berkshire’s largest position valued at around $175 billion, stood at about $60 billion as of Tuesday’s close.

The filing also revealed that Berkshire cut its Amazon holdings significantly, selling more than three quarters of its position. The move reduced Berkshire’s stake from a valuation of about $2.1 billion at the end of Q3 to roughly $457 million by the end of Q4. This marks one of the largest reductions in Berkshire’s exposure to a major tech stock in recent years.

These portfolio adjustments coincided with Buffett’s final quarter as CEO, closing a chapter on his decades-long leadership. Buffett officially retired at the end of 2025, handing the reins to Greg Abel. The timing of these sales underscores Buffett’s disciplined approach to portfolio management, trimming concentrated positions in tech while ensuring Berkshire remains diversified and resilient.

For investors, the takeaway is clear: Berkshire’s moves reflect caution toward stretched valuations in big tech, particularly amid ongoing concerns about overspending on AI. Apple and Amazon stocks still posted gains in Q4, but Berkshire’s divestments highlight the importance of balancing growth exposure with risk management as the market navigates volatility.

Big tech stocks have been the engine of market growth since late 2022, when ChatGPT ignited the AI boom on Wall Street. Companies like Apple, Amazon, Microsoft, and Nvidia rode a wave of investor enthusiasm, pushing valuations to historic highs. For nearly two years, these firms were seen as untouchable leaders, driving indexes higher and shaping the narrative around AI’s transformative potential.

But over the past six months, that momentum has stalled. Concerns about overspending on AI infrastructure, rising competition, and stretched valuations have weighed heavily on the sector. Investors are increasingly questioning whether the massive capital poured into AI projects will deliver sustainable returns, or if the market is entering a period of correction after the initial hype.

This context makes Berkshire Hathaway’s decision to trim its Apple and Amazon stakes especially significant. Warren Buffett’s moves often carry symbolic weight, and reducing exposure to two of the biggest tech names could reinforce investor caution. It suggests that even long-term believers in these companies are wary of inflated valuations and the risks tied to AI-driven spending.

For investors, the takeaway is clear: while big tech remains central to market leadership, confidence is fragile. Portfolio adjustments by influential players like Berkshire highlight the need to balance growth opportunities with risk management. The sector’s future performance will depend not just on innovation, but on proving that AI investments can translate into durable profitability.

Berkshire Hathaway made a dramatic cut to its Amazon holdings in the final quarter of 2025, selling 7.7 million shares more than 75% of its stake in the e-commerce giant. The position, worth about $2.1 billion at the end of Q3, was reduced to roughly $457 million by Tuesday’s close. This marks one of the most significant divestments Berkshire has made in big tech, underscoring a cautious stance toward growth-oriented firms amid stretched valuations.

The timing of the sale is notable, as Tuesday’s filing represents the last Berkshire portfolio update overlapping with Warren Buffett’s tenure as CEO. Buffett, who took over Berkshire in 1965 and transformed it into a $1 trillion insurance and investment powerhouse, officially retired at the end of 2025. Leadership has since transitioned to Greg Abel, who now oversees Berkshire’s vast portfolio and strategic direction.

Buffett’s exit from Amazon reflects his trademark discipline in portfolio management paring down concentrated positions and locking in gains while reducing exposure to volatility. Although Amazon remains a dominant force in e-commerce and cloud computing, Berkshire’s divestment signals caution about long-term growth prospects in a sector facing intense competition and heavy AI-related spending.

For investors, the move highlights the importance of watching Berkshire’s portfolio adjustments during this leadership transition. Buffett’s decisions often carry symbolic weight, and trimming Amazon reinforces broader concerns about tech valuations. As Greg Abel takes the helm, Berkshire’s evolving strategy will be closely scrutinized to see whether it continues Buffett’s cautious approach or embraces new opportunities in emerging sectors.

Apple stock rose nearly 7% in the fourth quarter, showing resilience even as Berkshire Hathaway trimmed its holdings. Unlike peers such as Meta and Alphabet, Apple has avoided heavy spending on AI infrastructure, and that restraint became a tailwind when the AI rally lost steam last quarter. Investors rewarded Apple’s disciplined approach, pushing shares higher despite broader concerns about tech valuations.

Amazon shares also posted gains, rising 5% in the same period. The increase came even as Berkshire sold more than three quarters of its stake in the e-commerce giant. Amazon’s performance reflects investor confidence in its core businesses cloud computing and retail despite questions about profitability and competition in the AI space.

The divergence between Apple and its Big Tech peers highlights how strategic spending decisions can influence stock performance. While Meta and Alphabet have faced skepticism over aggressive AI investments, Apple’s more measured approach has reassured investors. Amazon’s gains, meanwhile, suggest that strong fundamentals can offset portfolio divestments by influential players like Berkshire.

For investors, the key takeaway is that not all Big Tech stocks are moving in lockstep. Apple’s restraint on AI spending and Amazon’s steady growth show that fundamentals and strategy matter as much as hype. Berkshire’s portfolio adjustments may signal caution, but the market continues to reward companies that balance innovation with financial discipline.

Berkshire Hathaway’s decision to slash its Amazon stake by more than 75% and continue trimming Apple holdings marks a pivotal moment in Warren Buffett’s final quarter as CEO. These moves highlight a disciplined approach to reducing concentrated exposure in Big Tech, even as both Apple and Amazon posted gains in the fourth quarter.

Buffett’s exit strategy underscores caution toward stretched valuations and heavy AI spending across the sector. Apple’s restraint on AI infrastructure helped its stock rise nearly 7%, while Amazon gained 5% despite Berkshire’s divestment. The contrast shows that fundamentals and spending discipline remain critical drivers of investor confidence.

With Greg Abel now at the helm, Berkshire’s portfolio adjustments will be closely watched as signals of how the firm balances growth opportunities with risk management. The timing of these sales reinforces Buffett’s legacy of prioritizing stability and diversification, ensuring Berkshire remains resilient in a volatile market.

For investors, the takeaway is clear: Big Tech is no longer a guaranteed growth engine. Berkshire’s moves reflect broader caution about valuations and overspending in AI, reminding investors to weigh fundamentals over hype when positioning portfolios for the future.
