Are you gonna memorize it? Or you have an alternative way to “attack” it?

Just remember the crosses in the second part. Otherwise it is pretty straightforward.

[Factor one * (Beta(a)(b)] + [Factor two * (Beta©(d)] + [Covariance Factor, (Beta(a)(d) + Beta(b)©]

cov(i,j) = sum[bi*bj*cov(Fm, Fn)] Market i,j Factor m,n = {1,2} – Isn’t it much simpler than a micro attribution.

Beta(1) * Beta(2) * Variance / Sd1 * Sd2 = correlation.

come on guys, stop joking

Correction: cov(i,j) = sum[b(i,m)\*b(j,n)\*cov(Fm, Fn)] Market i,j Factor m,n = {1,2}
