I have return streams going down colums B through I
Dates are down column A
I want colum J to give me the weighted return for the streams of returns.
But it must re-allocate to funds that have performance and not count funds
that do not. So the Dec-01 portfolio return should be 50% fund 2, and 50%
Fund 3, and 0% fund 1
the allocations are in row 45 and should be flexible to be adjusted as
needed.
THANKS!
