SOXX is a semiconductor-focused equity ETF from IShares, while VGT is a technology-focused equity ETF from Vanguard. Neither fund clearly dominates on breadth, so the practical difference is more about weighting, index construction, and cost. VGT has the lower expense ratio, while SOXX charges more for its exposure.
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 53.8% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
Because SOXX and VGT are closer in breadth, the better fit usually comes down to index methodology, issuer preference, and cost. VGT has the lower expense ratio, while SOXX charges more for its exposure.
Concentration
The top three shared holdings explain 53.8% 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.
Shared Sector Tilt
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 SOXX and VGT.
