VFMO vs VGT: 15% overlap
Vanguard U.S. Momentum Factor ETF and Vanguard Information Technology ETF share 14.7% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.
Different holding dates. These holdings were published about 3 months apart — VFMO as of 2026-03-31, the rest through 2026-06-30. Each fund is compared using its most recent file, so any trading in between shows up as a difference.
