In June 2017, a sheep farmer became concerned that by the time his 80,000 kg wool crop was ready for delivery in November 2017 that the price would fall from its current $11.50 per kg to less than her $10.60 per kg break-even price.One wool contract is for 2,500 kg, and June, September and December wool futures prices are $11.45, $10.90 and $11.20 respectively.Show how this farmer can 'lock in' a profit for her business by entering and subsequently reversing a futures market position, if in November, the spot and December futures prices fell to $10.50 per kg and $10.40 per kg respectively.
