To determine the cost of a 6-month futures contract for a stock index, you need to consider the current value of the index, the risk-free rate, and the dividend yield. Given the following information:

• The current value of the stock index is USD 750.
• The risk-free rate, compounded continuously, is 3.5% per year.
• The dividend yield, compounded continuously, is 2.0% per year.

Using this data, calculate the cost of a 6-month futures contract for the stock index.
