the level of diversification within a portfolio mantarisk uses the definition according to choueifaty and coignard (2008) where this ratio considers both the number of assets in the portfolio and the correlations between them a higher diversification ratio indicates a more diversified portfolio, meaning the assets are less likely to move in the same direction, reducing overall portfolio risk
