AB’s Chief AI Officer, Andrew Chin, explores AI advances in Leveling the Divide Between Discretionary and Systematic Investing: How AI Enables Breadth and Depth. The research paper, recently published by The Journal of Portfolio Management, includes these key findings:

  • AI, especially large language models (LLMs), are dissolving the boundaries between traditional discretionary (fundamental) investing and systematic (quantitative) approaches.

  • LLMs broaden the reach of discretionary investors by applying their insights over a larger universe of investment opportunities. They also extend the nuance and depth of systematic investors by quantifying the qualitive.

  • In this new world, alpha generation will be driven by unique datasets, expert application and customization of LLMs through prompting and fine tuning, and the efficient delivery of actionable insights.
