ITOT is an equity ETF from IShares, while VUG is a U.S. growth equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. ITOT and VUG 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 34.1% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
Because ITOT and VUG are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. ITOT and VUG are priced very similarly on expense ratio.
Concentration
The top three shared holdings explain 34.1% 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.
