The bar chart and table below illustrate the annual calendar year returns of the Fund based on NAV as well as the average annual Fund returns. The bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year-to-year and by showing how the Fund’s average annual total returns based on NAV compared to those of a broad-based market index, specifically the S&P 500® Index. Additionally, the Fund has also included two additional indices for these purposes: the Dow Jones Global Index and the Nasdaq-100® Index. Further, on or about December 1, 2025 the Fund ceased tracking the Deepwater Frontier Tech Index and began pursuing an active investment strategy. Therefore, the Fund’s performance and historical

Performance Table Closing [Text Block]

The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Returns before taxes do not reflect the effects of any income or capital gains taxes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains.

Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Shares in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.
