Answer:
b. 13.3%
Explanation:
Calculation to determine What would be the percentage price change according to the duration- with-convexity rule
Using this formula formula
βP/P = -D*βy + (1/2) * Convexity * (βy)^2
Let plug in the formula
βP/P = -12 * -.01 + (1/2) * 265 * (.01)^2
βP/P = .12 + .01325
βP/P = .13325*100
βP/P=13.3%
Therefore What would be the percentage price change according to the duration- with-convexity rule is 13.3%
