We propose a new measure of disagreement based on connectedness, which generalizes the disagreement index introduced in Billio et al. (2018). Building on the lifting approach in Hendrickx (2014), we extend Billio et al. (2018) to signed networks, which allows us to consider more general consensus dynamics and disagreement with antagonistic behaviour. Synthetic and real-world ﬁnancial networks of serial correlation are considered for illustrating the new measure and for studying opinion dynamics and convergence to consensus on prices for ﬁnancial assets.
