Research

Every AI investing product now promises agents that continually learn and adjust. Strip away the marketing and that describes continuous re-fitting to recent data, which is the mechanism of overfitting. There is a right way to build adaptive models, and it is narrower than the pitch.

In 2020, the most successful quant fund in history lost more than 20 percent and told its investors it would not be changing the models. The investors who left anyway converted a temporary drawdown into a permanent loss. Every systematic strategy has years like this. What decides your outcome is the yardstick you use to judge them.
