FTSE Fallen Angel Indexes

The FTSE Time-Weighted US Fallen Angel Bond Index measures the performance of “fallen angels” (bonds which were previously rated investment-grade but were subsequently downgraded to high-yield). The index includes US Dollar-denominated bonds issued by corporations domiciled in the US or Canada that meet the inclusion criteria. Any such bonds, with a rating changed from investment-grade to high-yield in the previous month, are eligible for inclusion in the index and will be held in the index for a period of 60 months. If a bond exits and then re-enters the index, the inclusion period is reset.

Unlike traditional indices, where constituent weights are based on market value, the index’s constituent weights are determined based on the time from inclusion in the index. Higher weights are assigned to bonds that have more recently become “fallen angels”. This time-based weighting approach aims to capture the price rebound effect that fallen angels tend to experience soon after their initial downgrade to high-yield. Furthermore, issuers’ weights are  capped at 15% and constituents’ time-based weights are capped at 5 times their respective market value-based weights to help manage concentration risk.
