Conversely, it should lose approximately two times as much as SKHY when SKHY falls on a given day. The Fund does not seek to achieve two times (2x) the daily performance of SKHY (the “Daily Target”) for any period other than a day.While the Fund has a daily investment objective, you may hold Fund shares for longer than one day if you believe doing so is consistent with your goals and risk tolerance.
