Questions people ask

How much ETF overlap is too much?

Above 70% is high redundancy. 40% to 70% is moderate. Below 40% is genuinely complementary.

How is overlap calculated?

We compare the holdings of both funds and total the portfolio weight each one has in names the other also holds.

Why does overlap matter?

High overlap quietly removes the diversification you thought you were buying and concentrates your risk in a handful of names.
