XACT Bull is a leveraged exchange-traded fund that seeks to deliver roughly 150% of the daily positive movements of the OMXS30 Index, which includes the 30 most-traded stocks on the Stockholm Stock Exchange. To achieve this, the fund's portfolio is made up of liquid assets and OMXS30 futures contracts amounting to about 150% of its total value. The fund actively rebalances its futures holdings each day to maintain this level of leverage and may also use other derivative instruments to ensure its performance aligns with 1.5 times the daily gains of the underlying index.
