Price return from month-end closes, distributions reinvested at month end. Excludes trading costs, bid-ask spreads and taxes. Past performance says nothing about future returns and is not part of the composite score — see the methodology for what the score does measure.
Composite score
Based on a 0.40% expense ratio.
Based on $5.55B in net assets.
Top-10 holdings represent 17.1% of net assets.
US Corporate Bond base · ETF wrapper · 1.67% TTM yield.
The composite is a weighted average of the four core sub-scores above (cost, tax efficiency, liquidity, concentration). Missing sub-scores fall back to the per-category median when the category has at least 50% data coverage, so funds without (e.g.) parsed N-PORT holdings aren't accidentally boosted by renormalization. Tracking quality is shown where computable but isn't currently part of the composite weighting. See methodology for formulas, the tracking-quality partial-coverage rationale, and the dimensions we deliberately don't score (methodology v0.5.2).
