Susanne constructed a value-weighted index portfolio of AMZN, INTL, and CMCSA stocks last month (t=0) when the stock prices were $3156.13, $50.32, and $46.46, respectively. The number of shares outstanding is 0.5 billion for AMZN, 4.25 billion for INTL, and 4.64 billion for CMCSA. Today's stock prices (t=1) are $3,286.42, $52.97, and $44.95, respectively. There were neither dividend payments nor any changes in the number of shares outstanding. Tim constructed a portfolio at the same time using the same three stocks as Susanne but he constructed an equally weighted index portfolio.

Hint: It does not matter how much Susanne and Tim invested in their portfolios because I am asking you to calculate returns. However, if you want to use how much money they invested in their portfolios for convenience in your calculations, you can choose any amount, $100 million, for example.
