AuthorTopic: Beta for Bonds

While we use CAPM and beta to calculate the price of equity, theoretically could we use the same methodology to calculate beta for a bond? i.e. take a bond index and the price of a bond, regress etc to come up with a benchmark yield? And what do we do with the coupon??

With the CAPM, it's basically assumed that interest rates are fixed.
With bonds, you're primarily concerned with changes in interest rates (although credit downgrades etc are important).
Later (L2 ? L3 ? I forget) you'll see that duration plays the same sort of role for bonds as duration does for equities

I think you had a small typo at the bottom of your response. Duration plays the same sort of role for bonds as BETA does for equities.

Capm is not for Bonds

You could use a beta for a bond, but by the time you had enough data to even derive a characteristic line, it would be too late OR the characteristic would have changed. Stocks have permno's and basically are infinite in terms of the time they exist. Bond's have a repayment date.
