Comparing the convexity of two bonds directly
You can also investigate the influence of factors on bond convexity by pricing-up two bonds that vary only in this factor and then calculating the convexity of each bond directly.
In this exercise, you will find the convexity of two bonds; both will be 5 year bonds with a yield of 3% and face value of USD 100, but the first bond will pay a 1% coupon and the second bond will pay a 10% coupon.
