How to calculate
Calculate the trade needed to move one asset toward a target portfolio weight.
trade required = portfolio value × target weight − current holding
Worked example
Total portfolio value: 100000; Current value of selected asset: 30000; Target weight (%): 40.
Target asset value: 40,000 ; Trade required: 10,000 ; Current asset weight: 30 %.
Assumptions and limits
