Portfolio A : Weight 20%, Expected Risk 20% Portfolio B : Weight 30%, Expected Risk 15% Broad Market Index : Weight 50% What is the (Expected) Tracking Risk ?
is it sqrt of square of (0.2 X 0.2) + (0.3 X 0.15) + (2 X0.2X 0.2 X.15 X.3 X.5) No idea basically
Please note that Broad Market Index is the benchmark.
Sorry, the Broad Market Index is the benchmark and its expected Risk is 5%.
wouldn’t we need to know the returns of the market as well as the portfolios? Tracking error = Standard deviation of excess returns to a benchmark, so I’m having trouble incorporating the given information into a formula.
std deviation is bassically a risk and hence I incorporated. I am shooting from my a$$ here …no idea
I was thinking the same thing as you except my first 2 terms were squared…not sure how to incorporate that benchmark data.
Only the calculation of tracking (active) risk is required here.
8.5%?

^ that’s what I got with the method I described earlier (squaring the first terms)…however, it didn’t incorporate the benchmark at all…eh, fail for me on this topic.
sqrt((.2^2)((.2-.05)^2)+(.3^2)((.15-.05)^2)+(.5^2)((.05-.05)^2)) = 4.24%?

8.5 * 0.5 (market) can get you the same answer.

AMC, Where is this problem for? Schweser?
