IVW vs VV: 66% overlap
iShares S&P 500 Growth ETF and Vanguard Large-Cap ETF share 66.5% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.

Where IVW and VV differ

0.6% of IVW by weight, held in no part of VV.
31.7% of VV by weight, held in no part of IVW.
A large count with a small weight is the usual shape: the positions one fund adds are typically its smallest ones.

Frequently asked

How is the overlap between IVW and VV calculated?
