Optimal portfolio of HSBC UK bank

It is all about the bank HSBC UK where I am currently doing my internship. (All the figures, annual reports and etc. are available in their website and must be used accordingly as it going to be checked how accurate it is).The writer should come up with the Optimal portfolio at the end with an advice where you say you should invest with this amount of risk level and these and these and these assets, this amount of cash level and that would be optimal portfolio for hsbc UK bank. Simply. How it should look like. Based on theory to give an advice to the bank what is the optimal portfolio to invest in based on on the amount of risk level they want to be exposed to. ( end up with a graph that tells you what is the optimal point in which you have to invest) Main book that must be referred to is Jonathan Berk and Peter DeMarzo Corporate Finance-Global Edition book http://iman.sn/bibliotek/livres/filieres/banque-finance-assurance/pdfs/corporate-finance.pdf chapter 11 if I am not mistaken. Obviously, other sources should be used as well.
