Calculate Mean with Weights in a Column and Means in a Column
=SUMPRODUCT(Weights, Means)
Calculate Mean with Weights in a Column and Means in a Row
MMULT(Row,Column)
Calculate Portfolio Standard Deviation
SQRT(MMULT(TRANSPOSE(Weights),MMULT(VCov,Weigths)))
Delta Normal VaR
=Amount x Quantile x Scale x STD
Quantile = NORMSINV(Confidence) and Scale =SQRT(1/n)
GVMP
=MM(MINVERSE(Array),Ones)/MMULT(TRANSPOSE(Ones),MMULT(MINVERSE(Array),Ones))
Or
=MMULT(MINVERSE(Array),Ones)/SUM(MMULT(MINVERSE(Array),Ones))
Efficient Portfolio
=MMULT(MINVERSE(Array,Er-c MMULT(MINVERSE(Array),Er-c Weights))
Variance
W1^2Variance1+W2^2Variance2+2W1W2*Cov
Covariance Efficient with GMVP
=MMULT(TRANSPOSE(GVMPWeights),MMULT(VCOV, Efficient Weights))
