What Stands Out In This Comparison
What This Means
SMH is a semiconductor-focused equity ETF from VanEck, while VXF is an equity ETF from Vanguard. SMH and VXF do not own much of the same portfolio weight. That usually means you are combining different parts of the market, with only a small amount of duplication through names like MRVL, QRVO, and OLED.
How They Differ

What Drives The Overlap
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 100.5% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
