What This Means
IGV is a technology-focused equity ETF from IShares, while RSP is an equal-weight U.S. equity ETF from Invesco. IGV and RSP 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 FTNT, EA, and SNPS.

What Drives The Overlap
The overlap is driven by a relatively small set of large shared positions. The top three shared holdings account for 15.09% of the score, which means the result is heavily influenced by the biggest common weights rather than a long tail of tiny positions.
