Why These ETFs Overlap
QUAL is an equity ETF from IShares, while SPLG is a U.S. large-cap core ETF from SPDR. The overlap exists because both funds allocate meaningful weight to the same holdings. In this dataset, the biggest shared drivers are AAPL, NVDA, and MSFT, which appear in both portfolios and push the overlap score higher.
Holding both QUAL and SPLG can still be reasonable, but you should expect some duplication. The decision comes down to whether the non-overlapping parts of each ETF are important enough for your strategy.
