About These ETFs
What Stands Out In This Comparison
What This Means
SOXX is a semiconductor-focused equity ETF from IShares, while VGT is a technology-focused equity ETF from Vanguard. SOXX and VGT overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as NVDA, AVGO, and MU, which explains why the score lands at 25.94%.
How They Differ
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.
What Drives The Overlap
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.
When One May Fit Better
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.
