What Stands Out In This Comparison
What This Means
Both funds come from IShares. MTUM is an equity ETF, while SOXX is a semiconductor-focused equity ETF. MTUM and SOXX overlap enough to matter, but they still bring different exposures to a portfolio. The overlap is concentrated in holdings such as AVGO, MU, and NVDA, which explains why the score lands at 28.77%.
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 51.92% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
