Modified duaration :
Modified duration is a measurable change in the value of a security in response to a change in interest rates.
Modified duration = Duration / [ 1 + YTM ]
It specifies% change in Price in opposite direction due to 1%
change in YTM.
Particulars | Values |
Duration | 6.23 |
YTM | 14.0000% |
Modified Duration = Duration / [ 1 + YTM ]
= 6.23 / [ 1 + 0.14 ]
= 6.23 / [ 1.14 ]
= 5.4649 %
I.e 1% change in disc rate leads to 5.4649 % change in Bond Price
Change in Disc Rate is 3 %
% Change in Bond price for change in disc rate by 3 % is [ 5.4649 %
* 3 ]
I.e3 %change in Disc Rate leads to 16.3947 %
There is inverse relation between YTM and Bond Price, If yield increases, Price will decrease and Vice versa.
Option D is correct.
