So — partly overlapping. Should you hold both?
FTEC and SOXX 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 ~24 effective positions (grade C).
Holdings as of — FTEC: Jun 27, 2026 (Fidelity); SOXX: Jun 30, 2026 (iShares (BlackRock)). Refreshed monthly. Overlap is measured across each fund’s largest holdings (top 33); the diffuse long tail barely moves the math.
