Interpretation

Should you own both IWC and IBB?

IWC and IBB share 97 tracked holdings with 7.85% 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.
