Compare two to ten ETFs using their latest stored holdings. Returns pairwise shared holdings, weighted overlap (sum of the smaller weight for each shared holding), each fund's weight in shared names, and the largest duplicate exposures. Coverage is explicit because provider holdings may be partial top-holdings samples. Read-only.
