Interpretation

Should you own both IWS and IWR?

IWS and IWR share 698 tracked holdings with 80.79% 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.
