Under new CEO Greg Abel, Berkshire Hathaway has made a dramatic departure from Warren Buffett’s historical playbook, tripling its stake in Alphabet and investing over $2.6 billion in Delta Air Lines shares. This strategic pivot, coinciding with the departure of portfolio manager Todd Combs, signals a more growth-oriented approach for the conglomerate.
Live News
Berkshire Hathaway’s investment strategy has taken a notable turn in the months since Greg Abel assumed the role of chief executive. According to recent regulatory filings, the conglomerate significantly increased its holdings in technology and airline sectors—areas that Warren Buffett had long avoided or publicly criticized.
Berkshire tripled its stake in Alphabet, Google’s parent company, marking one of the largest single-sector bets in recent years. Additionally, the firm purchased over $2.6 billion worth of Delta Air Lines shares, a sector Buffett had famously shunned after selling airline positions during the pandemic.
The shift comes amid reports that Todd Combs, a key investment lieutenant at Berkshire, has departed the firm. Combs had been seen as a potential successor to Buffett’s investing mantle, and his exit may have paved the way for Abel to more directly shape the portfolio.
Abel’s moves suggest a willingness to embrace higher-growth, capital-intensive industries that Buffett historically avoided due to valuation concerns or cyclical risks. While Berkshire has held Apple for years, its broader tech exposure had remained limited. The new airline and tech bets represent a meaningful diversification away from the conglomerate’s traditional insurance and utilities focus.

Expert Insights
The strategic shift under Greg Abel suggests Berkshire Hathaway may be entering a new phase of portfolio management, one that balances its traditional insurance and energy roots with a greater appetite for growth-oriented sectors. Abel’s decision to triple the Alphabet stake aligns with broader market trends favoring large-cap technology names, but it also introduces valuation risk that Buffett’s value discipline had long sought to mitigate.
The airline investment carries its own set of challenges. Delta’s cyclical sensitivity to fuel costs, labor dynamics, and economic downturns contrasts with Berkshire’s historically defensive posture. While the move could generate significant returns in a strong travel environment, it also exposes the conglomerate to sector volatility.
Todd Combs’ departure further reshapes the leadership landscape. With Abel now firmly in control, investors may watch for additional portfolio adjustments in the coming quarters. The changes underscore that Berkshire’s investment philosophy is evolving—but whether this will enhance long-term shareholder value remains to be seen. Market participants will likely monitor future filings for clues about Abel’s broader strategy.
