The money-weighted average return gives more weight to a return when there was a deposit before that return, and less weight to a return when there was a withdrawal before that return.
Here, for the money-weighted return, the 4% return gets more weight than the 10% return, and the -2% return gets more weight than the 4% return. You have the lowest weight on the highese return, and the highest weight on the lowest return: the money-weighted average will be lower, so the time-weighted average will be higher.
What is the rationale behind -2% being alloted more weight as compared to 4%? No where has it been mentioned that the fund manager deposits more money with every successive year. Kindly help me walk through this.
Suppose that the manager deposits $100 at the beginning of each year.
Year 1: Beginning balance is $100, return is 10%, ending balance is $110, weight on the 10% return is $100
Year 2: Beginning balance is $210, return is 4%, ending balance is $218.40, weight on the 4% return is $210
Year 3: Beginning balance is $318.40, return is -2%, ending balance is $312.03, weight on the -2% return is 318.40.
The time-weighted average return is [(1.10)(1.04)(0.98)]^(1/3) – 1 = 3.8845%
The money-weighted average return is 1.9791%.
