Berkshire Hathaway's Equity Stakes in Amex, Alphabet, and Ally
Berkshire Hathaway holds over $300 billion in equities. GN stocks/banks highlights three positions with distinct business drivers: American Express's fee model, Alphabet's cloud backlog, and Ally Financial's margin expansion, including a recent stake reduction in the latter.
Berkshire Hathaway holds a portfolio of approximately 30 publicly traded stocks valued at more than $300 billion. GN stocks/banks identifies three positions with distinct fundamental drivers: American Express, Alphabet, and Ally Financial. These companies exhibit specific competitive advantages and valuation profiles that differentiate them from broader market peers.
American Express and Alphabet represent core holdings with strong cash flow generation. Ally Financial, however, saw a 7% reduction in Berkshire’s stake during the second quarter. This trim appears strategic, likely intended to maintain ownership below the 10% regulatory threshold, rather than a reflection of deteriorating business fundamentals.
American Express Leverages Affluent Customer Base
American Express operates as both a lender and a payment network, a model shared by only a few global competitors. This dual role allows the company to capture interest income on outstanding balances and fee income on every transaction, regardless of whether cardholders pay their statements in full. The company’s focus on affluent cardholders provides a defensive buffer against potential contractions in broader consumer spending.
As Berkshire’s second-largest equity investment, American Express benefits from a stable revenue stream that is less sensitive to economic volatility than traditional consumer credit providers. The company’s pricing power and customer retention metrics support its valuation, offering a consistent risk-reward profile for investors seeking exposure to the financial sector.
Alphabet Cloud Division Drives Rapid Growth
Alphabet has become Berkshire’s fourth-largest investment following significant capital deployment in the second quarter. The company’s Google Cloud division reported 82% revenue growth in the latest quarter, accompanied by a $514 billion backlog of contracts. This growth rate exceeds that of larger technology peers, indicating effective market share acquisition in the enterprise infrastructure segment.
Both Google Services and Google Cloud generate substantial cash flow, supporting Alphabet’s capital allocation strategy. Despite its scale and profitability, the company trades at an earnings multiple that remains reasonable compared to other mega-cap technology firms. This valuation gap suggests that the market has not yet fully priced in the sustained growth trajectory of its cloud infrastructure business.
Ally Financial Benefits From Margin Expansion
Ally Financial, the largest non-automaker auto lender in the United States, holds over $100 billion in retail deposits. In a higher-for-longer interest rate environment, the company’s net interest margin expands as loan yields rise faster than deposit costs. This structural advantage drives profitability without requiring significant increases in deposit liabilities.
Berkshire’s 7% stake reduction in Ally likely serves to keep ownership below the 10% threshold that triggers heightened regulatory scrutiny. Since Ally regularly repurchases its own shares, the reduction helps maintain compliance without exiting the position. The stock currently trades at a discount to book value, presenting a risk-reward dynamic that contrasts with the premium valuations of its larger banking peers.
