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. Seemethodologyfor formulas, thetracking-qualitypartial-coverage rationale, and the dimensions we deliberatelydon't score(methodology v0.5.1).
