So — partly overlapping. Should you hold both?
SOXX and VT 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 ~56 effective positions (grade B).
Holdings as of — SOXX: Jul 30, 2026 (iShares (BlackRock)); VT: Jun 30, 2026 (Vanguard). Refreshed monthly. Overlap is measured across each fund’s largest holdings (top 50); the diffuse long tail barely moves the math.
