In his first year as CEO, Greg Abel has steered Berkshire Hathaway into sectors long avoided by Warren Buffett, notably technology and airlines. The conglomerate tripled its Alphabet stake and acquired over $2.6 billion in Delta Air Lines shares, signaling a strategic pivot following the departure of key investment manager Todd Combs.
Live News
Berkshire Hathaway’s investment strategy has taken a notable turn under new Chief Executive Greg Abel, who has overseen a significant expansion into technology and airline holdings—sectors that Warren Buffett historically sidestepped. According to recent filings and reports, Berkshire boosted its stake in Alphabet Inc. by roughly threefold, while pouring more than $2.6 billion into Delta Air Lines shares.
The moves come in the wake of Todd Combs’ departure from the investment team, a shift that many analysts view as a catalyst for a more growth-oriented, tech-heavy portfolio. While Buffett famously avoided airline stocks after selling his positions early in the COVID-19 pandemic, Abel appears willing to revisit the sector, betting on a cyclical rebound in air travel demand.
The increased exposure to Alphabet, a major player in digital advertising and cloud computing, mirrors a broader trend among value-oriented investment firms that have started to embrace mega-cap tech names. However, the size of the stake suggests Abel may be positioning Berkshire for longer-term growth rather than short-term trading.
Neither Berkshire Hathaway nor Delta Air Lines have commented publicly on the specific transactions. The changes have raised questions about how much of the investment decision-making power remains with Buffett, who still serves as chairman but has handed day-to-day portfolio management reins to Abel.

- Sector implications: The moves could signal confidence in tech and travel recovery, potentially influencing other institutional investors to reassess their own positions in these sectors.

Expert Insights
Market participants have noted that Abel’s early actions represent a departure from the conservative, insurance-heavy portfolio Buffett built over decades. While Buffett has occasionally invested in tech—most notably Apple—he largely avoided big bets on Alphabet and airline stocks. Abel’s willingness to embrace these sectors may indicate a more diversified, growth-seeking mandate for Berkshire’s $300+ billion equity portfolio.
However, caution remains warranted. The airline industry remains sensitive to fuel costs, labor disputes, and macroeconomic headwinds. Similarly, big tech valuations face regulatory scrutiny and competition from artificial intelligence startups. Analysts suggest that Abel’s moves could be a calculated bet on post-pandemic travel trends and digital advertising resilience, but they also carry risks that Berkshire’s previous leadership deliberately sidestepped.
Investors will be watching upcoming quarterly reports for further clues on Berkshire’s evolving investment thesis. The shift may also influence how the broader market perceives conglomerate-style investing, especially if Abel continues to target high-growth sectors over traditional value plays. As always, such strategic pivots are subject to market conditions and should be evaluated with a long-term perspective.
