Tom Russo hails Warren Buffett's Alphabet wager, sees bigger risk than AI crash

Tom Russo praises Berkshire Hathaway’s recent $4.3 billion (17.8 million‑share) stake in Alphabet as a smart bet — noting Alphabet’s strong cash generation, below‑market P/E, willingness to fund long‑term “moonshots,” and its central role in commerce and advertising after a near‑40% rally into Sept. and further gains — but warns its heavy AI spending (capex forecast >$90 billion in 2025) may not deliver scalable returns or sustain past margins. Russo’s firm also holds sizeable positions in both Alphabet ($1.1 billion) and Berkshire ($1.8 billion), underscoring his conviction; however, he flags a bigger systemic risk: the doubling of US federal debt over the past decade (to >$38 trillion) and attendant pressures on bond and currency markets that could weaken the dollar and create broader financial and geopolitical disruption.

Analysis

Berkshire Hathaway disclosed a 17.8 million‑share position in Alphabet valued at $4.3 billion as of Sept. 30, a move Tom Russo calls a winning bet; Alphabet’s stock rallied nearly 40% in the quarter to $244 and climbed a further ~17% to clear $285, implying Berkshire could have turned an early‑quarter ~$3.1 billion cost into a ~$5.1 billion market value by the most recent close. Russo’s own firm held $1.1 billion of Alphabet and $1.8 billion of Berkshire, together representing 31% of its $9.3 billion U.S. equity portfolio, underscoring conviction among value managers in Alphabet’s durable cash generation and strategic position. Alphabet trades at a below‑market price‑to‑earnings multiple while maintaining substantial cash flows and a stated willingness to fund moonshots; management projects capital expenditures in 2025 will exceed $90 billion, reflecting aggressive investment in AI and infrastructure. Russo cautions that heavy AI and capex outlays may not yield scalable, superior returns sufficient to sustain prior search margins, and he flags a larger systemic risk: U.S. federal debt has nearly doubled from under $20 trillion in 2016 to over $38 trillion today, creating pressure to service liabilities and potential strains in bond and currency markets that could weaken the dollar and create broader financial disruption.

Key Decisions for Investors

• Consider a measured exposure to Alphabet (GOOGL) given Berkshire’s sizable stake, below‑market P/E and strong cash generation, but scale positions with phased buys to avoid buying into momentum alone
• Monitor Alphabet’s capex trajectory and AI monetization metrics closely—if 2025 capex (> $90 billion) fails to produce improving margins or scalable returns, reassess valuation and reduce exposure
• Prepare for macro tail risk from rising U.S. debt and dollar pressure by reviewing duration and currency exposures, considering hedges to protect portfolios from bond and FX market stress
• Watch subsequent Berkshire and Alphabet filings for timing and sizing of transactions and avoid concentration risk by limiting any single‑name position relative to portfolio risk budgets
