It involves ensuring the constraints are presented as part of the matrix standard form. You will typically have the constraint that all assets sum to one, i.e. the matrix-vector equation: $$ \delta^T x = 1 $$ If you want to create an inequality constraint for assets in a sector just isolate them:

Web1. I'm trying to optimize a portfolio using cvxpy. My original construction is the following: w = Variable (n) ret = mu.T * w risk = quad_form (w, Sigma) prob = Problem (Maximize (ret), [risk <= .01]) which is just maximize return under some risk constraint. However, I would like to also have a weights/leverage constraint, like the following: Web1 I'm trying to optimize a portfolio using cvxpy.
