I am lost from my lecture, and I cannot contact my prof for now...but I got to do the HW.

can someone tell me what do I need to know to answer the question below?

Thank you very much!

1) Calculate value of DJIA on 5/1/19, putting formula in cell D45

2) Put weight calculations (formulas) in columns F and G

3) Use HPRs in column I to calculate return on price-weighted and market value-weighted portfolios over the 5/1/2019 to 9/26/2019 period.

4) Use column N to demonstrate that a $2 increase in price in any of the 30 stocks will produce the same % change in the price-weighted index.

5) What types of companies are among the group which have the 5 highest HPRs over the 5/1/19 - 9/26/19 period? What does that tell you?
