Lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio of securities. Sector ETFs are subject to sector risks and non-diversification risks, which may result in greater price fluctuations than the overall market. Because the fund invests in ETFs, it indirectly bears its proportionate share of the operating expenses of the underlying funds. Indirectly, the fund is subject to all risks associated with the underlying ETFs.
The guarantee on U.S. government securities applies only to the underlying securities of the Fund's portfolio, and not to the value of the Fund's shares.
Because the Fund holds a limited number of securities, it will be impacted by each security's performance more than a Fund with a larger number of holdings.
