AGG is a fixed-income ETF from IShares, while BND is a fixed-income ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. AGG and BND are priced very similarly on expense ratio.
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 1.93% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
Because AGG and BND are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. AGG and BND are priced very similarly on expense ratio.
Concentration
The top three shared holdings explain 1.93% of the full overlap score.
That helps show whether the score comes from a handful of giant shared positions or from a broader mix of common holdings.

Sector tags are not consistently available for the biggest shared positions in this dataset, so this comparison leans more on the specific holdings than on sector labels.
These are the holdings contributing the most to the overlap score between AGG and BND.
