Based on the investment portfolio given, the weighted average ROR of the investments would be 2.1%
First, find the total portfolio value:
= 2,600 + 3,700 + 575 + 1,225
= $8,100
The weighted average Rate of Return (ROR) on the investments is:
= (2,600 / 8,100 x 1.7%) + (3,700 / 8,100 x 3.2%) + (575 / 8,100 x 12.9%) + (1,225 / 8,100 x -5.6%)
= 2.076
= 2.1%
