An AI portfolio manager is a system that decides what a portfolio buys, sells and holds without a human making the final call. It reads a research brief, weighs it against the current holdings and risk rules, then issues orders. A human typically builds the system and enforces limits but does not override individual decisions.
On each trading day the AI reviews its book, the latest data on candidate stocks, and market conditions, then decides to trade or pass. Well-designed systems apply hard constraints — position-size caps, cash limits, no leverage — that the model cannot violate.
Because the model both explains and executes, its notes can be published, giving an unusually transparent view of "why" behind each position. That transparency is part of what makes AI-run books useful as a learning tool.
