You just joined a new upstart firm that is focused on managing investments and particularly excess returns. Your goal is to find whether you can use any of the models you know to predict those excess returns. You have managed to secure a few clients that are interested in investing. Specifically, you have two clients: Tony Soprano and Al Capone. Tony is interested in having a portfolio of assets $($more than $2$ assets$),$ while Capone is interested in individual assets $(1$ asset$).$ Both clients want you to pick the assets to be used. please show this in excel
