We construct portfolios based on characteristic weights and develop a novel way to measure capacity of these portfolios to absorb capital. Our estimates suggest that portfolio capacity is the highest for fundamental-weights, whereas portfolios based on momentum, equal risk budget, and equal...

Firms with similar characteristics display similar expected returns. Defining neighbouring assets as those with the most similar set of characteristics, I show that past returns of an asset's neighbours predict its future expected returns. If a majority of an asset's neighbours have performed...

We propose a portfolio allocation method based on risk factor budgeting using convex Nonnegative Matrix Factorization (NMF). Unlike classical factor analysis, PCA, or ICA, NMF ensures positive factor loadings to obtain interpretable long-only portfolios. As the NMF factors represent separate...
