1.Daily settlement with a futures contract

A speculator bought a CME British pound futures contract (62,500) four days ago at the rate of $1.25/ and closes the position today at the rate of $1.26/. During the four-day investment horizon, the same futures contract with the same maturity was sold at the following prices:

Day 0: Position open at the rate of $1.25/

Day 1: $1.26/

Day 2: $1.28/

Day 3: $1.27/

Day 4: $1.26/

a.Calculate the daily gain/loss for the four days.

b.What is the total gain/loss from this investment?

c.Answer the above two questions assuming the speculator short the contract instead of long (buy) the contract.

2. Draw a profit profile of the following options and indicate 1) what is the break-even price, 2) what is the maximum gain, and 3) what is the maximum loss. (Hint: refer to textbook page 290-293, exhibit 8.5, 8.6, 8.7 and 8.8)
