Return a normalized side-by-side comparison of two to ten ETFs across selected classification, market, fund-data, cost, income, benchmark, price-performance, price-risk, and holdings modules. Leaders are mechanical extrema, not recommendations. Currency and partial-holdings caveats are explicit. Read-only.
