Daily UpdateEquitiesCommoditiesRates CreditInformation TechnologyFinancials

The market remains driven by an aggressive AI-led rally in equities, even as geopolitical tensions stall progress on Iranian oil exports. Technical indicators show elevated retail leverage, while macroeconomic signals suggest potential volatility as cross-asset relationships like Copper vs. Nasdaq break down.

Key Takeaways

  • 1.Equities rally driven by AI infrastructure, while S&P ex-AI segments lag.
  • 2.Increased competition in AI may paradoxically drive higher aggregate investment due to an arms-race mentality among hyperscalers.
  • 3.Oil markets face a 'trust deficit' as US-Iran talks stall, complicating the pricing of Iranian supply.
