Macro ThematicEquitiesRates Govt BondsRates CreditEnergyInformation Technology

Key Takeaways

  • 1.Traditional 60/40 portfolios are facing synchronized drawdowns as stock and bond correlations rise materially.
  • 2.Private equity and credit may offer 'smoothed' returns due to appraisal pricing, but often share the same underlying risk exposures as public markets.
  • 3.GMO's ALTA fund (GAAGX) uses a multi-strategy approach including merger arbitrage, carry, and trend-following to provide uncorrelated returns.
