The Fund generally seeks to remain fully invested at all times in financial instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. The Fund seeks to rebalance its portfolio each day so that its exposure to ANT is consistent with the Daily Target. ANT’s movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if ANT has risen on a given day, net assets of the Fund should rise (assuming there were no Creation Unit redemptions). As a result, the Fund’s exposure will need to be increased. Conversely, if ANT has fallen on a given day, net assets of the Fund should fall (assuming there were no Creation Units issued). As a result, the Fund’s exposure will need to be decreased.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.
