Example explains Diversity Score
Technically speaking, the diversification score measures the number of uncorrelated assets that would have the same loss distribution as the actual portfolio of correlated assets. For example, if a portfolio of 100 assets had a diversification score of 50, this means that the 100 correlated assets have the same loss distribution as 50 uncorrelated assets.
