The sum of the smaller position weight for every holding found in both funds. It measures duplicated capital, not merely the number of repeated names.
Below 30% usually indicates distinct exposure. 30–60% deserves inspection. Above 60% often means the funds play similar portfolio roles.
Holdings describe what a fund owns; correlation describes how prices moved. Funds can share few securities and still react similarly to the same economic forces.
High overlap is not automatically bad. It is a problem when duplication is accidental, adds fees, or creates more concentration than the investor intended.
