Strategy. The Fund invests at least 80% of its total assets in component securities of the Cboe Russell 2000 BuyWrite Index (the "Underlying Index") or in investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities, either individually or in the aggregate. The Fund's 80% investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed. The Underlying Index measures the performance of a theoretical portfolio that holds a portfolio of the stocks included in the Russell 2000 Index (the "Reference Index"), and "writes" (or sells) a succession of one-month at-the-money covered call options on the Reference Index.

The Fund's 80% investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed. The Underlying Index measures the performance of a theoretical portfolio that holds a portfolio of the stocks included in the Russell 2000 Index (the "Reference Index"), and "writes" (or sells) a succession of one-month at-the-money covered call options on the Reference Index. The written covered call options on the Reference Index are held until expiration. The Reference Index is an equity benchmark which measures the performance of the small-capitalization sector of the U.S. equity market, as defined by FTSE Russell (the "Index Provider"). In seeking to track the Underlying Index, the Fund follows a "buy-write" (also called a covered call) investment strategy on the Reference Index in which the Fund purchases the component securities of the Reference Index or purchases other investments (including other underlying ETFs) that have economic characteristics that are substantially identical to the economic characteristics of such component securities, and also writes (or sells) call options that correspond to the Reference Index. Each calendar month, the Fund will write (sell) a succession of one-month call options on the Reference Index and will cover such options by holding the component securities of the Reference Index, or in investments that have economic characteristics with substantially identical economic characteristics of such component securities, either individually or in the aggregate. Each option written will (i) have an exercise price generally at or above the prevailing market price of the Reference Index; (ii) be traded on a national securities exchange; (iii) be held until expiration (i.e., generally the third Friday of the month) and be settled based on the final settlement price of the option; (iv) expire on its date of maturity (in the next calendar month); (v) only be subject to exercise on its expiration date; and (vi) be settled in cash. In return for the payment of a premium to the Fund, a purchaser of the call options written by the Fund is entitled to receive a cash payment from the Fund equal to the difference between the value of the Reference Index and the exercise price of the option if the value of the option on the expiration date is above its exercise price. The Fund's covered call options may partially protect the Fund from a decline in the price of the Reference Index through means of the premiums received by the Fund. However, when the equity market is rallying rapidly, the Underlying Index is expected to underperform the Reference Index. The Underlying Index is sponsored by the FTSE Russell Index Provider, which is an organization that is independent of, and unaffiliated with, the Fund and Global X Management Company LLC, the investment adviser for the Fund (the "Adviser"). The Fund's investment objective and Underlying Index may be changed without shareholder approval. The Index Provider determines the relative weighting of the securities in the underlying index and publishes or designates a third-party index calculation agent to publish information regarding the market value of the Underlying Index. The Adviser uses an indexing approach to try to achieve the Fund's investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally uses a representative sampling strategy with respect to the Underlying Index. "Representative sampling" is an indexing strategy that involves investing in a representative sample of securities (including indirect investments through underlying ETFs) that collectively has an investment profile similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. Underlying ETFs may constitute a substantial portion of the Fund's assets. These include country weightings, market capitalization and other financial characteristics of securities. Under normal circumstances, at least 80% of the Fund's total assets will be invested in component securities of the Underlying Index or in investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities, either individually or in the aggregate. The Adviser expects that, over time, the correlation between the Fund's performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. The Fund concentrates its investments (i.e . , hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2025, the Underlying Index was not concentrated in any industry. Show less
