we form a stock index by using only two stocks in the index.
One of the stocks is the Stock-A. The current selling price of the stock-A is 103 dollars and the second stock is the stock-B. The current selling price of the stock-B is 56 dollars.
The current value of the index is equal to 267 dollars. Stock-A pays a dividend of 13 dollars in 1 months.
Stock-B pays a dividend of 1.3 dollars in 2 months.
We form a futures contract written on this index expires in 3 months.
Currently, the finance cost of carry in the market is 0.42% per month.
How can we calculate the futures contract's theoretically fair value which is monthly compounding.
Should I use the formula $f(T)= S_{stock}(1+r)^T-D_T$ ?
I don't understand how can I use this formula when for two dividend payments and two different stocks exist?
Can you please give me a hint to solve this question?
