EFA vs VGT: 0% overlap
iShares MSCI EAFE ETF and Vanguard Information Technology ETF share 0.3% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.

Where EFA and VGT differ
Sector weights as a share of each fund, ordered by the size of the gap rather than the size of the sector — two funds that overlap heavily still usually diverge somewhere.

Δ is EFA minus VGT, in percentage points. Sector data is not published by every issuer, so “Unclassified” is a real category rather than a gap in the table.

Frequently asked
How much do EFA and VGT overlap?

How is the overlap between EFA and VGT calculated?
As the sum of the smaller weight in each fund, over every holding both funds own: Σ min(wA, wB). If EFA holds a stock at 6% and VGT holds the same stock at 4%, 4% counts as shared. The result is bounded between 0% and 100%, and it is computed after looking through any fund-of-funds to the underlying holdings.
