Goldman Desk Gamma Squeeze and Trading Strategy

Market ReportEquitiesRates Govt BondsDerivativesInformation TechnologyHealth Care

The S&P 500 rally is being sustained by a narrow group of AI-linked mega-caps and a massive call-buying gamma squeeze. However, Goldman Sachs warns that surging global long-term yields are likely to break this momentum loop.

Key Takeaways

  • 1.The S&P 500 rally is exceptionally narrow, driven entirely by the 'Magnificent 7' and specifically Nvidia, while the rest of the market is a net drag.
  • 2.A historic gamma squeeze with nearly $3 trillion in call notional is forcing dealers to buy stocks, creating a positive momentum feedback loop.
  • 3.Rising long-term yields (US 30Y > 5% and JGB 30Y at multi-decade highs) are the primary threat to current equity valuations.
