Our estimate of the impact of potential defaults on investor returns, based on historical default and recovery rates for bonds of similar credit rating and maturities.
See RATING tab for calculations of ALTAR Score™
Estimate of fund sensitivity to interest rate changes based on modified duration and convexity adjustment applied to underlying bonds. Note: Less meaningful for inflation-indexed bonds.
Adds expected inflation to real YTM for inflation-linked bonds so that all instruments are compared on a nominal basis
Weighted-average term to maturity of the cash flows from a bond. All else being equal, bonds of longer duration are more sensitive to changes in interest rates than bonds of shorter duration.
Approximation of the change in bond prices given a 100 basis point shift in interest rates. A better estimate, particularly for larger moves in interest rates, is provided by the Rate Sensitivity Analysis below.
