HHI Based Diversification Index
Description
divHHI calculates a portfolio diversification index DIV. The DIV is equal to 1 minus the Herfindahl-Hirschman Index (HHI), which is defined as the sum of the squared portfolio weights. The maximum HHI of a long-only portfolio is 1, which occurs when all of the portfolio's investment is in a single asset, and correspondingly HHI = 0.
