Its bets against Russell 1000 Growth

Each stock's weight of the fund's net assets less its weight in the Russell 1000 Growth, in points.

Holds much more than the index

Holds much less, or none

About these numbers

Holdings from the fund's N-PORT report to the SEC, public 60 days after the report date. Every weight is a percent of the fund's net assets, as the fund publishes it, and active weights are that less the index's weight. Only stocks are listed, so cash, bonds and derivatives are not, and a fund that borrows can hold stocks worth more than its net assets. Active share compares the fund's stocks alone with the index.
