Interpretation
Should you own both SIZE and IWD?
SIZE and IWD share 428 tracked holdings with 47.31% overlap in the imported holdings set. High overlap can be fine when the funds serve a deliberate role, but it can also mean less diversification than the ticker count suggests.
Use the portfolio analyzer to test your actual allocations. Pairwise overlap does not account for how much of each ETF you own.
