Hedging bond portfolios against infinitely many ranked factors of risk
Esperanza H. Montagut and María José Pérez-Fructuoso
The paper considers bond portfolios affected by both interest rate and default-risk. In order to guarantee a correct performance of our analysis, we will hedge against an infinite number of factors. Hence, we do not have to impose and do not depend on any assumption concerning the dynamic behavior of the term structure of interest rates. On the other hand, since a complete hedging is not feasible unless some ideal situations hold, we rank the factors according to the empirical evidence. Thus, we make the most important risks vanish, and minimize the effect of those kinds of risk less usual in practice.
