Please help with the following problem.
Create your own index given the following data:
Number
of shares Closing Prices (per share)
Companies outstanding Day T Day T+1
1 2,000 $30.00 $35.00
2 6,000 55.00 50.00
3 3,000 22.50 25.00
4 4,000 40.00 42.50
Assume that a stock value weighted index consisted of the four issues above. What are the values of the index for Day T and for Day T+1 and what is the change?
Please notice that it is the "value weighted index". Please show steps.
