What Is How to Check ETF Overlap and Why It Matters?
ETF overlap occurs when multiple funds in your portfolio hold the same underlying stocks. A portfolio with SPY, QQQ, and VTI may look diversified but can have 60%+ overlap in large-cap technology names, creating hidden concentration risk.
Why It Matters
Investors often add ETFs to reduce risk, but without overlap analysis, they may inadvertently increase concentration. During sector rotations, overlapping ETF portfolios amplify losses rather than providing the expected downside protection.
