Your colleague uses regression analysis to generate Key Rate Durations (KRDs) s follows: KRD Regression Statistics Index Vol R 1.0000 Intercept 0.0000000 KRD 1 (0.0419717) KRD 2 (0.0804181 KRD 3 (0.1139467 KRD 4 (0.1635074) KRD 5 (0.1853961) F Test 169,333 SSE 0.00002 Obs 30 a) Estimate the KRD for the 6th year b) If rates for year 1 and 2 are expected to increase by 0.10% at each point, drop by 0.20% for year 3 and 4 at each point, increase 0.50% at year 5 and drop 0.60% at year 6, what is the estimated percentage change in the value of the bond
