4. I have gone short on 150 contracts of the August 23 Lean Hogs at 95.95 . (NOTE: Lean Hogs are quoted at cents per pound s095.95=$0.9595 per lb was my shorting price for 150 contracts). a) If I were to cover all 150 contracts at a price of 100.50 what is my ROI? (10 pts) b) What instructions should I have put in place to ensure that the maximum loss this transaction would have incurred is about 25% ? (10 pts)
