Using these assets, you have a choice of either combining [FG] or [FH] in a single portfolio, on an equally-weighted basis.

Required: Calculate the absolute percentage difference in the coefficient of variation (CV) between the stock portfolio [LM] and the portfolio which outlines the optimal combination of assets.

Answer% Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places (for example: 28.31%).

From above analysis of Portfolio F-G and F-H noted that Portfolio F-h has higher return in comparision to Portfolio F-G, Hence for a risk taking customer Portfolio F-H would be optimal one.

Since Portfolio F-H has been identified as optimal portfolio, below is the computation of for Coefficient of Variation for Portfolio F-H and absolute difference in Coefficient of Variation for portfolio L-M and F-H.

Coefficient of Variation of Portfolio F-H

--- > (Standard Deviation of Portfolio / Portfolio Mean)*100
