The aim of this paper is to propose an alternative way to determine the well known confidence parameter c in the Black-Litterman (BL) asset allocation model. Starting at t0 and considering a dynamic BL optimization over time we are able to build a manager confidence function that sets the c value upon the manager’s views. We’ll explain that an endogenous confidence parameter solves the old problem to require views to the manager, together with their ex-ante strength. Following this way we attain a BL model with a reduction of manager’s inputs, without losing the benefits of the BL approach.
