AI-driven structural growth is reshaping global indices, causing massive geographic weight shifts toward Taiwan and South Korea while creating record levels of market concentration. Traditional bond-equity diversification is weakening, requiring investors to seek alternatives like real assets and liquid alternatives.

Key Takeaways

  • 1.AI is fundamentally restructuring global equity indices, leading to Taiwan and South Korea overtaking traditional developed markets like the UK and France in index weight.
  • 2.Market concentration risk is reaching extreme levels, particularly in emerging markets where a single security (TSMC) now accounts for over 14% of the index.
  • 3.Traditional bonds are failing as diversifiers because correlations with equities have risen to historical highs amidst persistent inflation and policy uncertainty.
