Minimum Variance Portfolio:
A minimum variance portfolio is a collection of securities that
combine to minimize the price volatility of the overall portfolio.
with the given weights to securities/ Assets in portfolio,
portfolio risk will be minimal.
Weight in A = [ [ (SD of B)^2] - [ SD of A * SD of B * r(A,B) ] ] /
[ [ (SD of A)^2 ]+ [ (SD of B)^2 ] - [ 2* SD of A * SD of B * r (A,
B) ] ]
Weight in B = [ [ (SD of A)^2] - [ SD of A * SD of B * r(A,B) ] ] /
[ [ (SD of A)^2 ]+ [ (SD of B)^2 ] - [ 2* SD of A * SD of B * r (A,
B) ] ]
A =Xillow
B = Yash
Particulars | Amount |
SD of A | 4.0% |
SD of B | 3.0% |
r(A,B) | -0.3000 |
Weight in A = [ [ (SD of B)^2] - [ SD of A * SD of B * r(A,B) ]
] / [ [ (SD of A)^2 ]+ [ (SD of B)^2 ] - [ 2* SD of A * SD of B * r
(A, B) ] ]
= [ [ (0.03)^2 ] - [ 0.04 * 0.03 * -0.3 ] ] / [ [ (0.04)^2 ] + [ (
0.03 )^2 ] - [ 2 * 0.04 * 0.03 * -0.3 ] ]
= [ [ 0.0009 ] - [ -0.00036 ] ] / [ [ 0.0016 ] + [ 0.0009 ] - [ 2 *
-0.00036 ] ]
= [ 0.00126 ] / [ 0.00322 ]
= 0.391304
