$7.$ compute daily simple returns earned on these portfolios from $20220103$ to $20231229$ assuming that the portfolio is always rebalanced, at no cost$,$ back to the weights you initially computed.

$8.$compute the daily simple returns earned on these portfolis from $20220103$ to $20231229$ assuming that the portfolios are not altered after they are constructed. This is called a static allocation. You may assume that you can buy fractional units of shares and that the price paid for shares is that listed on $20211231.$

how should i calculate these two questions. i have the allocation vectors and daily asset return. Just multiply them and add up or what else
