Following an Iran ceasefire, markets have rallied on AI optimism and compressed risk premia, yet Goldman Sachs warns that re-escalation risks and valuation overhangs in AI necessitate robust tail hedging.

Key Takeaways

  • 1.The recent relief rally following the Iran ceasefire has compressed risk premia, but a re-escalation in the Middle East remains a major underpriced tail risk.
  • 2.Physical shortages in the AI supply chain and commodity markets are primary drivers of current capital flows and asset outperformance.
  • 3.US growth pricing has likely overshot realistic levels, standing at 2.5%, which is consistent with the market looking past near-term weakness.
