SGOV vs VGT: what actually overlaps
SGOV and VGT: 0% of a dollar ends up in the same companies either way (SEC Form N-PORT, 2026-05-31), across 0 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, SGOV behaves like 17.2 equally weighted positions and VGT like 15.1. Held together in equal size they behave like 32.1 — 14.9 more than SGOV on its own. They share no securities at all, so the pair genuinely widens.
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 2026-05-31), 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.

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.
