| Risk [Text Block] | Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and ETFs, its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses. An ETF is subject to ETF specific risks and may trade in the secondary market at a price below the value of its underlying portfolio, may not be liquid and may be halted by the listing exchange. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track. |
