Calculating Active Security Returns, Reading 54, Practice Problem 2
I understand the concept of active security returns, but I'm having trouble with part of the answer to practice problem #2 in this reading.
In the third part of the answer it shows how to calculate the active portfolio return from the active weights multiplied by the active security returns. I can't figure out how the active security returns are calculated from the information given. In the answer to the problem they give the active security returns as 2%, 3%, 0%, -4% and -2%. How are those numbers calculated?
