Inside Warren Buffett’s Portfolio

A Closer Look at Berkshire Hathaway’s Sector Strategy and Major Moves
​Warren Buffett’s investment philosophy has long been studied as a masterclass in patience, value, and conviction. A snapshot of Berkshire Hathaway’s holdings reveals a portfolio heavily anchored in traditional cash-generating giants, balanced by significant, high-conviction bets in technology, media, and homebuilding.

​The Core Pillars: Sector Allocation
​Rather than chasing fleeting market trends, Berkshire Hathaway’s capital is concentrated across five primary sectors:

​Finance (34.60%): Financial institutions remain the bedrock of the portfolio, accounting for more than a third of total holdings.
​Information Technology (22.04%): Tech represents the second-largest slice, driven largely by massive legacy positions.
​Communications (15.52%): Media, telecom, and digital platforms form a substantial third pillar.
​Consumer Staples (14.16%): Everyday household brands provide defensive stability.
​Energy (8.97%): Traditional oil and gas producers round out the major allocations, with the remaining 4.72% spread across other industries.
​The Heavyweights: Top Portfolio Holdings

​At the top of the position list, a handful of mega-cap companies command tens of billions of dollars in market value:

Company Ticker Shares Held Position Value Ownership Stake
Apple Inc. AAPL 227.91M $65.95B 1.55%
American Express Co. AXP 151.61M $51.28B 22.08%
Coca-Cola Co. KO 400.00M $32.50B 9.30%
Alphabet Inc. (Class A) GOOGL 78.79M $28.15B 0.65%
Bank of America Corp. BAC 483.39M $27.54B 6.74%
Chevron Corp. CVX 84.37M $13.98B 4.23%
Occidental Petroleum OXY 264.94M $12.86B 26.72%
Chubb Limited CB 34.24M $11.67B 8.78%
Moody's Corp. MCO 24.66M $11.17B 13.91%
Alphabet Inc. (Class C) GOOG 27.18M $9.60B 0.22%

Apple remains the single largest holding by dollar value at $65.95 billion, followed closely by longtime financial staple American Express at $51.28 billion. Meanwhile, Berkshire commands massive ownership percentages in several key companies—holding 26.72% of Occidental Petroleum, 22.08% of American Express, and an extraordinary 37.08% of Sirius XM Holdings ($3.68B).

​Notable Position Increases and Strategic Bets

​Beyond its established giants, the data highlights aggressive accumulation in specific areas:
​Doubling Down on Alphabet: Berkshire significantly expanded its stake in Google’s parent company. Class A shares (GOOGL) jumped by 24.54 million (+45.24%), while Class C shares (GOOG) surged by 23.6 million—a massive 658.35% increase. Combined, the two share classes represent $37.75 billion in value.

​Return to Aviation: Delta Air Lines (DAL) saw a notable boost of 17.51 million shares (+43.99%), bringing the total stake to 57.32 million shares valued at $5.36 billion (8.72% ownership).
​A Bet on U.S. Homebuilding: Residential construction features prominently across the portfolio. Lennar Corp.

Class A (LEN) saw an addition of 15.93 million shares, bringing the position to 26.03 million shares worth $2.12 billion (alongside a smaller stake in Lennar Class B). Berkshire also maintains positions in building materials supplier Louisiana-Pacific (LPX, $445.59M) and fellow homebuilders NVR Inc. ($75.71M) and D.R. Horton ($580.5K).

​Diverse Mid-Tier and Niche Holdings
​Further down the roster, Berkshire holds substantial stakes in legacy media, retail, and specialty finance—including 9.70% of The New York Times Co. ($1.09B), 9.80% of VeriSign ($2.26B), 8.74% of Ally Financial ($1.24B), and 6.16% of Kroger ($2.16B). Even smaller positions like Macy's ($173.03M) and Nucor Corp.

($413.81M) reflect an eye for tangible assets and established cash flows, while Constellation Brands (STZ) shows a closed-out position of zero shares.
