Weighted allocation brings character to cloning. Models based on weighted allocation attempt to draw benefit from the relative size of the stock picks held in source managers’ portfolios.
The process of assembling the models from a determined number of stock picks from a single manager or a group of managers based on selection criteria is similar to the equal allocation model described in chapter 15. The weighted model takes wing when it comes to allotting assets: Distribution is done based on a weightage associated with each pick. This weightage is derived from the percentage allocation in the source manager portfolios.
