We also introduced briefly a few of the bond sectors: government, corporate, and securitized. In this chapter we take a deeper look at how these risk measures can be tied together into a joint estimation of risk for fixed income.
We will start Part Two with a discussion of the issues unique to fixed income that must be dealt with up front in this chapter. The most immediate features of fixed income markets that we must grapple with are their sheer size, variety, and illiquidity. These features present us with very real problems from both a modeling and a physical resource (i.e., computers) perspective. Our approach to overcoming these problems will lay the framework for how we view the individual components of the total risk, specifically the interest rate, rate volatility, spread, bond idiosyncratic, and currency risks. We will introduce a method for linearizing the fix income return equation, and discuss what this means for the concepts of risk exposure and risk factor.
