Greg Abel Makes Bold Portfolio Moves as Berkshire's New Leader -- Dumps Amazon While Buying an Airline Stock

Berkshire Hathaway CEO Greg Abel sold all of its Amazon shares and initiated a Delta Air Lines position, highlighting a shift in capital allocation. Delta reported 2Q adjusted revenue up 14% YoY to $17.7B, but profitability fell 24.3% to $1.6B, while the stock is still up 51% over the last year through July 21. By contrast, Amazon’s 1Q results showed >28% YoY revenue growth to $37.6B and 22% operating income growth to $14.2B despite a planned ~$200B capex push for AI.

Analysis

The actionable read-through is not a broad endorsement of either company; it is a signal about where durable reinvestment still deserves a premium versus where cyclicality is doing the heavy lifting. AMZN is the higher-quality compounding asset because incremental AI/cloud spend can still translate into operating leverage if utilization and attach rates hold; the near-term risk is mostly FCF optics, not a broken earnings model. That makes any headline-driven weakness in AMZN a better entry point than chasing DAL on sentiment alone.

DAL is a tougher underwriting case because the equity is still a levered call on fuel, wages, and capacity discipline. Even when weaker competitors disappear, the industry has a habit of reintroducing competition through fare wars or capacity shifts, so the second-order effect is often margin normalization rather than a true rerating. Relative to peers, DAL can work tactically, but the broader airline basket remains vulnerable to any macro soft patch or energy spike.

The contrarian point is that the market may be overinterpreting a portfolio move as a fundamental verdict. Berkshire-style selling of a cash-generative platform business and buying a cyclical carrier reads more like valuation and sizing discipline than a structural downgrade/upgrade call. Falsifiers are straightforward: AMZN needs continued AWS acceleration without a material FCF miss, while DAL needs sustained unit-revenue strength with stable fuel; otherwise the airline upside should fade quickly.

Key Decisions for Investors

• Long AMZN / short DAL as a 3-6 month dollar-neutral pair; target 10-15% relative outperformance if AWS reaccelerates while airline margins stay range-bound. Risk is a benign fuel tape and strong consumer demand keeping DAL bid.
• Use 6-9 month AMZN call spreads to express the AI/capex payoff with defined downside; prefer on pullbacks rather than chasing strength. Thesis breaks if AWS growth slows for two quarters or capex drives a persistent FCF miss.
• Fade DAL strength with 3-6 month put spreads or a tactical short into earnings, especially if crude or labor costs re-accelerate. Cover if management reiterates capacity discipline and unit revenue holds above consensus.
• No direct trade in BRK.B/BRKA; treat the move as a sentiment signal only. If the market starts to extrapolate this into a durable pro-airline / anti-tech regime, that is likely the contrarian entry point for AMZN relative value.
