A textile manufacturer has made an agreement to deliver 100,000 t-shirts in 2 months. There is a concern that the price of cotton, which is the main material used in manufacturing, may fluctuate considerably during the following months. It is estimated that 0.10 kg of cotton will be needed to manufacture each t-shirt. Currently, the spot price of cotton is Co=20$/kg and standard deviation of the cotton price is $2. It is also known that the price of silk is correlated with the cotton. The current price of silk is SO=$50/kg and the standard deviation of the silk price is $4. The correlation coefficient between the cotton price and the silk price is given as 0.80. Assume that the monthly interest rate is 10% per year compounded continuously. The manufacturer wants to hedge his risk against unexpected increases in the price of cotton What is the total amount of cotton needed :( kg Suppose that the manufacturer can make forward contract with a counterpart to buy cotton in 2 months, what should be the forward price of cotton in the contract assuming that there is no holding cost? $ (Two decimal digits) (write long/short) If there is a futures market for cotton, what is the strategy of the manufacturer if he wants to minimize his risk? units of cotton contract (in terms of kg of cotton). Suppose that there is no futures market for cotton, but there is a futures market for silk. What position should the manufacturer take in silk futures to minimize his risk?
