The sector table uses each fund's sector allocation, and the top-holdings comparison each fund's disclosed largest positions.

Data & methodology disclaimer
This tool is for education, not investment advice. Holdings and sector data come from public market-data feeds, reflect each fund's most recently disclosed top positions, and can lag the fund's actual portfolio. Overlap computed from disclosed top holdings is a lower bound. Always verify against the fund provider's official holdings file before making decisions.
