Active share
How differently the money is placed, counting weights: one minus the sum of the smaller weight of each security across the fund and the index. 100% means nothing in common; 0% means the index itself. Two funds can hold the same names and still have a high active share if they weight them very differently.
Weight overlap
The share of money two portfolios hold in the same securities at the same weight. Above 50%, holding both is close to holding one of them twice.
Already in the index
The fund’s weight in securities the S&P 500 holds at all. A fund can be made entirely of index names and still have high active share, because it holds them at different weights.
Top ten
The weight of the ten largest holdings. Above 50% the fund is a bet on a handful of companies, whatever the theme.
