So — partly overlapping. Should you hold both?
ITOT and VIG 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 ~81 effective positions (grade A).
