The AD&Co US Mortgage High Yield Index (USMHY) tracks the total return of the bonds issued within the CRT programs of Fannie Mae and Freddie Mac. USMHY is an informational, investment-oriented monthly index of the return components: price, coupon, paydown, and credit loss. Accompanied by standard risk metrics from our models, the index is useful for comparisons with individual CRT bonds or relative value to other credit markets.

Investors and fund managers can use the index to assess the broad market returns, risks and opportunities available through investing in a market-weighted, passive portfolio of US mortgage credit risk transfer instruments. The Index also provides a means of comparing the returns of an actively managed portfolio against a passive, naive market portfolio as approximated by the Index. The Mid-Tier and its sub-indices allow for approximations of performance comparisons by vintage or age, across the capital stack, and by initial credit risk level and/or vintage as indicated by original attachment point.
