Fund Overlap and Hidden Concentration
Ticker count is not diversification. Two income ETFs can share the same top ten names.
What it is
Overlap is the shared weight between two portfolios. High overlap means a single factor (Nasdaq mega-caps, energy, etc.) drives both.
Overwrite funds on the same index are almost designed to overlap. That can be fine if you intended one bet. It is not fine if you thought you built a barbell.
Hypothetical: 40% shared weight
Labeled hypothetical — not a live yield, AUM, or tax bracket.
- You put $10,000 in Fund A and $10,000 in Fund B. If they share 40% by weight, $8,000 is the same underlying risk.
- A 20% drop in that shared sleeve is not “diversified away.”
- Measure the real pair in the ETF overlap tool — do not use this 40% as a live statistic.
Who this is not for
- Using overlap as a reason to own only one stock.
What people get wrong
- Assuming different issuers means different holdings.

FAQ
What is ETF overlap?
The shared holdings (by weight) between two funds. High overlap means you did not diversify as much as the ticker count suggests.
Why does overlap matter for income ETFs?
Overwrite funds often sit on the same mega-cap names. A Nasdaq crash can hit JEPQ, QQQI, and QYLD together.
Where do I measure it?
The ETF overlap tool at /tools/etf-overlap.
