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.
