So — partly overlapping. Should you hold both?
VGT and VTI share a meaningful core of the same megacaps, but each also brings real exposure the other lacks. Held together they keep a shared megacap core but each still pulls in exposure the other lacks, so a 50/50 blend spreads to ~28 effective positions (grade C).
Holdings as of — VGT: May 31, 2026 (Vanguard); VTI: May 31, 2026 (Vanguard). Refreshed monthly. Overlap is measured across each fund’s largest holdings (top 50); the diffuse long tail barely moves the math.
