• Warren Buffett has officially stepped down as CEO of Berkshire Hathaway, with Greg Abel now leading the company.
• Under Abel, Berkshire has reduced its Apple stake, acquired homebuilder Taylor Morrison, and made a large investment in Alphabet's AI infrastructure.
• These moves mark a clear shift in capital allocation priorities that investors are watching closely.

Berkshire Hathaway (NYSE:BRK.B), recently trading at $485.79, is entering a new chapter with Greg Abel at the helm after Warren Buffett's exit as CEO. The stock has returned 43.0% over the past 3 years and 74.3% over 5 years, figures that help frame what is at stake as this leadership change filters through to portfolio decisions. Investors now have fresh data points to assess how Abel is choosing to deploy Berkshire's considerable resources.

The immediate repositioning, from trimming Apple to buying into housing and AI infrastructure, gives investors concrete signals about how Berkshire might prioritize sectors and capital allocation in this post Buffett era. As more quarterly filings and deal activity emerge, the focus will likely be on whether this approach leads to a different risk mix and return profile for shareholders over time.

For investors, the leadership transition matters less as a headline and more for how Berkshire Hathaway’s US$397b cash and insurance float are being used. Greg Abel’s early moves, including reducing the Apple stake and directing capital into Taylor Morrison and Alphabet’s AI infrastructure, point to a tilt toward owning and funding operating businesses in housing and technology. That sits alongside Berkshire’s existing mix of insurance, railroad, energy, manufacturing and consumer-facing subsidiaries, which produced US$11.3b of operating earnings in Q1 2026.

Apple was a defining Buffett era position, so trimming it and reallocating to housing and AI infrastructure gives you fresh information about how Abel sees sector concentration and opportunity. At the same time, Berkshire is still carrying close to US$400b in cash and Treasuries, and analysts have flagged 1 key risk, with earnings expected to decline by an average of 2.4% per year over the next 3 years. The combination of large cash reserves, concentrated sector bets and a forecast earnings decline means the quality of Abel’s capital decisions will likely be a central focus for current and prospective shareholders.

The Risks and Rewards Investors Should Consider

• ⚠️ A larger tilt toward U.S. housing through Taylor Morrison, on top of existing exposure via Clayton Homes and Lennar, can increase sensitivity to weak real-estate and mortgage conditions.
• ⚠️ Analysts expect earnings to decline by an average of 2.4% per year over the next 3 years, so investors need to judge whether these new housing and AI infrastructure moves are enough to counter that pressure.
• 🎁 Berkshire still holds a very large cash and Treasury position, which gives Abel flexibility to pursue further acquisitions or buybacks without being forced into less attractive opportunities.
• 🎁 The shift toward owning and financing operating businesses in housing and AI related infrastructure is consistent with Berkshire’s long term focus on cash generating subsidiaries funded by insurance float.

What To Watch Going Forward

From here, it makes sense to watch how the Taylor Morrison acquisition is integrated alongside Clayton Homes and railroad and utility operations, and how quickly the Alphabet AI infrastructure investment ramps within Berkshire’s capital base. Any further changes to large equity positions, including Apple, will help you track how concentrated Berkshire wants its listed portfolio to be. Updates on operating earnings, insurance underwriting profit and float growth will show how much capacity Abel has to keep backing housing and AI infrastructure while still maintaining the current cash buffer.
