1. Calculating the expected return, standard deviation and geometric mean:

Average return 12.99%

Standard deviation 12.78%

Geometric mean returns 12.28%

% 3.74% 13.25% 14.78% 4.04% 16.75%
There is relevant relationship between the arithmetic mean and geometric mean, where
the arithmetic mean only averages the overall returns of the stock. On the other hand, geometric
mean provides compounding value of the returns, which is more precise and accurate. The above
valuation indicates that the average mean is higher than the geometric mean, as the total returns
of the assets are compounded.

The correlation matrix provides the overall linkage between each asset, which is used by
the investors to formulate an adequate diversified portfolio, which can increase returns and
reduce any kind of risk from investment.

The above table provides information on the overall return and risk attributes of the
investor’s utility, which is has been calculated in the above table. Therefore, from the relevant
calculation, it is detected that the return of 15.00% and standard deviation of 14.64% has the
highest investor utility.

From the relevant calculation, it can be detected that the total the total return of 15% and
a standard deviation of 14.64% has the highest investor utility.
8. Explaining the reasons for any differences between the utility-maximising target:
There is specifically no difference between the investor utility of unrestricted and
restricted efficient frontier, as there has been no negative investments conducted to achieve the
desired portfolio.

10. Identifying the assumptions that would be undertaken for the overall analysis:
The above analysis directly indicate that the overall portfolio would provide returns to the
investors, which could generate high level of income from investment. The risk-free rate is
considered to be higher, which can help in detecting the accurate level of income from
investment. The expected return in risky stock are lower only when the economic condition of
the country is not favourable and is headed towards a down trend. This is the main reason behind
the lower expected return for the risky assets. The major sense of fundamental uncertainty is
relevantly based on the occurrence of an economic crisis, which has been anticipated by the
financial analyst. The change in the movement of the capital market would directly impact the
overall valuation and anticipation of the financial analyst (Dymski 2016).

8FINANCIAL ECONOMIC
Moreover, the CAL line has been calculated by using the highest value of risk and return
that could be generated from the portfolio. This would eventually help in understanding the
efficient frontier, which depicts about the portfolio that has the lowest risk involved with the
investments. Therefore, assets with low return, high risk and high correlation would directly have
negative impact on the formulated portfolio of the investors.
