Summary

JPMorgan’s cross-asset strategy team built eight AI-driven investment agents that shift between stocks and bonds as growth and inflation conditions change. In a July 9 note led by Thomas Salopek, the strategists said the best-performing agent beat a traditional 60/40 portfolio by 0.7 percentage point a year over 20 years of backtests and did so with 2.8% lower annual volatility. All eight agents outperformed the benchmark on a risk-adjusted basis, posting Sharpe ratios of 0.74 to 0.95 versus 0.61 for the 60/40 portfolio, and also beat JPMorgan’s own rules-based regime model. The bank said the agents used off-the-shelf models from OpenAI and Anthropic, but cautioned that the results came from historical simulations rather than live trading and should not be over-interpreted. The test adds to a broader debate over whether AI can move beyond assisting analysts and into direct capital allocation, even as critics warn that flexible models can overfit past data and that crowded AI-driven trades could worsen market stress.
