Hidden AI correlations turn hedge funds into one crowded trade
The Perfect Storm That Clobbered Hedge Funds
The episode shows how leverage, options mechanics, and concentrated AI exposure can defeat the diversification investors expect from multi-strategy funds.
- 1Multi-strategy funds suffered simultaneous losses as supposedly distinct portfolios converged on leveraged, crowded AI positions.
- 2Negative gamma, leveraged ETFs, volatility-control funds, and systematic selling amplified the post-election market decline.
- 3AI’s next test is operational and financial, spanning electricity, funding, customer quality, equity supply, and cloud monetization.
Don't miss
Michael Ball explains how negative gamma, leveraged ETFs, volatility-control funds, and systematic traders mechanically amplified the post-election sell-off.
The brief
October’s hedge fund losses were unusually broad: major multi-strategy firms lost money together, challenging their role as portfolio stabilizers.
Nishant Kumar argues that crowded, leveraged AI positions created hidden correlations across strategies, while falling stocks, weak bonds, and political shocks left few places to hide.
The episode’s risk-machine tension is whether centralized managers can detect correlations before a sell-off, rather than only after pods have been cut or closed.
Michael Ball traces the post-election liquidation to negative gamma, leveraged ETFs, volatility-control funds, and systematic strategies that mechanically intensified the decline.
The broader AI trade now faces questions about financing, electricity, execution, customer concentration, equity supply, and whether hyperscalers can monetize continued compute growth.
