WebNov 3, 2016 · The risk contribution of asset k to the portfolio variance is σ p k 2 = w k 2 ∂ σ p 2 ∂ w k = w k ∑ j σ k j w j where we have used the fact that σ i j = σ j i. Note that σ k 2. It is easy to see that the sum of the individual risk contributions add up to the portfolio variance as ∑ k σ p k 2 = ∑ k j w k σ k j w j = σ p 2 Share Improve this answer WebThen, the amount of capital allocated to asset1 = 1/9 / (1/9 + 1/5) = 35% and amount allocated to asset2 = (1 - 35%) = 65%. As seen, 65% is allocated to asset2 as it has less risk of 5% compared to asset1 which has the risk of 9%. You can check that the formula you gave: is algebraically equivalent to .
