The impact of the Index’s movements during the day will affect whether the Fund’s portfolio needs to be re-positioned. For example, if the Index has risen on a given day, net assets of the Fund should rise, meaning that the Fund’s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall, meaning the Fund’s exposure will need to be reduced.
