ETF Overlap Tool — Quickly Identify Overlapping Holdings Across Up to 10 ETFs

The ETF Overlap Tool on ETF-Rankings.com is one of the most powerful and efficient ETF overlap tools available. While most overlap tools only compare two ETFs at a time, this tool allows investors to analyze up to ten ETFs simultaneously — revealing all 45 possible overlap combinations in seconds.

ETF overlap is one of the most misunderstood risks in portfolio construction. Investors often believe they are diversified simply because they hold multiple ETFs, only to discover that many of those funds own the same underlying companies. This tool makes those hidden similarities immediately visible, helping investors understand whether their ETF lineup is truly diversified or just repeating the same exposures in different wrappers.

Why the ETF Overlap Tool Is Different

  • Compare up to 10 ETFs at once, not just two
  • Instantly see overlap across 45 ETF pairings
  • View the top 25 common holdings shared across your selected ETFs
  • No charts or gimmicks — just clean, actionable data

By showing both percentage overlap and shared holdings, the ETF Overlap Tool allows investors to quickly identify redundancy, unintended concentration, and opportunities to improve diversification. Many users are surprised to learn that even a portfolio with five or six ETFs can still be heavily concentrated in the same handful of stocks.

Why it matters: Better diversification doesn’t come from owning more ETFs — it comes from owning complementary ETFs. This tool helps you get the best bang for your buck by identifying which ETFs actually add new exposure and which ones simply duplicate what you already own.

How to Use the ETF Overlap Tool

  1. Enter up to ten ETF tickers
  2. Instantly view overlap percentages across all ETF combinations
  3. Review the top common holdings shared across your ETFs
  4. Identify redundancy and improve portfolio efficiency
