The words on this page

Active share
The part of the fund doing something the index is not, as a percentage. It is the part a fee is actually buying.
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 very different weights.
Top ten
What the ten largest positions add up to. The higher it is, the more the fund is a bet on a few companies rather than a theme.
