Generally there are two broad ways of doing it: 1. Combining positions of the individual signals 2. Regress future returns against the signals to get expected returns of each asset In this

Here we will talk about another approach where we can sum up our positions, and still integrate a factor risk model, without having to explicitly extract the expected returns of the underlying assets.
