Assume an investor purchases a(n) 6-year, $1,000 bond at par. The bond has a coupon rate of 7%. The market rate almost immediately falls to 5.4 percent. What would be the percentage return on the investment if the buyer borrowed part of the funds with a 20 percent margin requirement? Assume the interest payments on the bond cover the interest expense on the borrowed funds.
