Market Trigger and Self-Referential Meltup Feedback Loop

Macro ThematicEquitiesDerivativesMacro Economic IndicatorsInformation TechnologyEnergy

The market is experiencing a massive gamma-driven meltup fueled by US economic growth and mechanical rebalancing in tech/semis ETFs. Nomura's Charlie McElligott warns that this self-referential loop could collapse as options expire and mechanical flows turn into forced selling.

Key Takeaways

  • 1.The market is currently in a 'self-referential meltup feedback loop' driven by five factors: US economic reacceleration, earnings growth in AI constraints (Semis/Energy), fund underpositioning, mechanical gamma flows, and leveraged ETF rebalancing.
  • 2.A record $2.6 trillion in S&P calls was purchased in a single week, creating an unprecedented gamma squeeze characterized by 'spot up, vol up' dynamics.
  • 3.Leveraged ETF rebalancing has contributed +$115B of buying power over the past month, with 85% of AUM concentrated in Tech and AI Semis.
