What is enhanced indexing in fixed income?

Question

AcadiFi · Accepted Answer

Enhanced indexing is a semi-passive strategy that closely tracks a bond index while taking modest, well-diversified bets to generate incremental alpha. Portfolio-wide risk factor exposures (duration, curve positioning, overall credit beta) stay near benchmark, but the manager exploits relative value within cells: issue selection, sector rotation within narrow bands, and tactical positioning around rebalance flows.

Typical risk/return profile: tracking error 20-75 basis points annualized (versus 10-30 bps for pure passive and 100-250 bps for active), alpha target of 15-50 bps net of fees, information ratio target 0.3-0.6.

For Kettlewood Enhanced Core tracking Bloomberg US Aggregate: duration bet limited to +/- 0.25 years versus benchmark; credit beta within +/- 0.1 of benchmark; sector tilts capped at 2% overweight/underweight. Within these bounds, the team identifies cheap bonds (new issue concessions, downgrade-oversold names, mispriced MBS pools) and fades expensive ones.

Common alpha sources: (1) new-issue concessions (buying on IPO of $500M+ corporates averages 3-8 bp concession over secondary), (2) fallen angel plays (downgraded bonds often trade below fundamental value for 30-60 days), (3) yield curve roll-down, (4) rich/cheap analysis between similar issuers, and (5) tactical TBA basis trading in MBS.

Risk controls: daily VaR against benchmark, sector concentration limits, duration-neutral positioning tested under rate shocks, and stress testing against 2008, 2013 taper tantrum, and 2020 liquidity crunch scenarios. Enhanced indexing suits investors who want index-like risk but incremental return for an active fee (typically 15-30 bps).
