I have an assignment about finance. That says that you are an analyst and should make a recommendation regarding asset allocation in a portfolio to a manager of an investment bank.

I have 4 stocks and risk-free asset (T-bill). I found the optimal 4 stocks portfolio with formula, then I draw an efficient frontier that represents the combination of risk-free asset and 4 stocks portfolio (see attached image).

But I am not sure of how to make a recommended portfolio. From what viewpoint or perspective should I decide recommended asset allocation??

Conditions: Rf= 0,2%, Rm=0.6, Rp=0.5% p=1.8%

Portfolio ii Efficient Frontier | | | 0.80% 0.70% 0.60% 0.50% 040% 0.20% 0.10% 0.00% 0.00% 0.50% 1.00% 1.50% 2.00% 2.50% 3.00% 3.50% Portfolio ii Efficient Frontier | | | 0.80% 0.70% 0.60% 0.50% 040% 0.20% 0.10% 0.00% 0.00% 0.50% 1.00% 1.50% 2.00% 2.50% 3.00% 3.50%
