Suppose that you are a speculator who trades three-month Eurodollar futures. On November 5, you sell two December three-month Eurodollar futures contracts at 96.81. The subsequent weekly quotes for the closing December Eurodollar futures price are as follows:
Date: 11/12 11/19 11/26 12/3
Price: 96.92 97.08 96.77 96.63
Calculate the weekly values in your margin account. The initial margin is $650 per contract and the maintenance margin is $400. Calculate your realized return for the entire period. Assume that you offset your futures position on December 3 at the price indicated.
