What are the duration and modified duration of a seven-year, 3.5 percent coupon rate, annual coupon payment, $1000 par value government note priced today to yield 3 percent to maturity (use the text formulas or Excel’s Duration and MDuration functions)? What is the convexity of this instrument? [Recall that Bonds and Bond Properties.xls illustrates these calculations.] Using one of the following approximation formulas with yield data in decimal form,
[if text formula] % Change in Price 100 (-1.0 Duration (YieldNew-YieldOld)/(1+YieldOld)),
[if Excel function] % Change in Price 100 (-1.0 MDuration (YieldNew-YieldOld)),
What is the approximate percentage change in this bond's price if yields on comparable securities rise to 4 percent? What is the actual percentage change in this bond's price if yields on comparable securities rise to 4percent (use a financial calculator or Excel’s PV function)?
