What is Key Rate Duration ?

Only know that it is usefull for Bond portfolio where there is a non-parallel shifts in YTM, Other than that dont know anything

I wrote an article on key rate duration that may be of some help: http://financialexamhelp123.com/key-rate-duration/

Note, however, that this is really a Level II topic. I wouldn’t worry about it at Level I.

But it is given in LOS 56.d

In that case . . . read the article.

Thank you !

My pleasure.
