Abstract

In this short article, we extend Kelly, Malamud, and Pedersen (2023)’s new asset pricing framework to allow incorporating multiple predictive signals into optimal principal portfolios. Empirically, we find that the multi-signal theory is valuable for combining signals and improving a naive combination of single-signal principal portfolios.
