QQQM vs VUG: what actually overlaps

QQQM and VUG: 62.67% of a dollar ends up in the same companies either way (SEC Form N-PORT, 2026-05-31 and 2026-06-30), across 56 securities the two funds both hold. Every free comparison tool can list the tickers in common; this weights them, which is the part that decides whether owning both changes anything.

The short version

Held alone, QQQM behaves like 32 equally weighted positions and VUG like 19.8. Held together in equal size they behave like 26.4 — less diversified than holding QQQM on its own. The two funds hold 56 of the same securities, 62.67% of a dollar by weight, so the pair buys those companies twice.

Overlap here is the sum, over securities both funds hold, of the smaller of the two weights: the share of a dollar that sits in the same company either way. Matching is on CUSIP. Figures are as of each fund's own reporting date (2026-05-31 and 2026-06-30), which do not always align.

Not 50/50, or holding a third fund alongside these two? The portfolio calculator runs this same math for any weights, across up to 12 funds.

Each fund on its own: QQQM · VUG

Where the overlap actually is

56

The ten shared positions that account for the most of it, with what each fund holds of its own. Shared is the lesser of the two — the part that is held in common either way. Where the two columns diverge, one fund is making a larger bet on that company than the other, and holding both does not average it away.

By country of issuer

2026-05-31 · 2026-06-30

Where each fund's money sits by the issuer country its filer reported (incorporation, not revenue). Two funds can share companies and still differ here, and a pair that looks diversified by name can be one country twice.

What each fund did last quarter

Each fund's newest filing against its previous one. A pair whose overlap is rising or falling does so because of these moves; the figures are the same ones on each fund's page and in its feed.

Sources and limits

Computed from SEC Form N-PORT (NPORT-P), the portfolio report every registered US fund files. Positions below 0.001% of net assets are dropped; weights are normalised to each filing's own total.

Unit investment trusts including SPY and DIA do not file N-PORT, so no overlap can be computed for them. Where a comparison is missing from this site, that is usually why rather than an oversight.

Overlap says what is held in common, not what will move together. Two funds with no shared holdings can still fall together, and the effective holding count takes no account of correlation. All 275 pairs are in the concentration dataset, and every fund's own history is on its fund page.
