Strategy. The Fund employs a passive management or indexing investment approach designed to track the performance of the Index. The Fund generally uses a representative sampling strategy to achieve its investment objective, meaning it generally will invest in a sample of the securities in the Index whose risk, return, and other characteristics resemble the risk, return, and other characteristics of the Index as a whole. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in the constituent securities of the Index, each of which is a security issued by a small-cap company, identified in accordance with the Index Providers (as defined below) market-capitalization selection parameters, that is incorporated … Show more… The Fund employs a passive management or indexing investment approach designed to track the performance of the Index. The Fund generally uses a representative sampling strategy to achieve its investment objective, meaning it generally will invest in a sample of the securities in the Index whose risk, return, and other characteristics resemble the risk, return, and other characteristics of the Index as a whole. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in the constituent securities of the Index, each of which is a security issued by a small-cap company, identified in accordance with the Index Providers (as defined below) market-capitalization selection parameters, that is incorporated and headquartered in the United States. The Index Providers market-capitalization selection parameters generally provide that the Index will be composed of the top scoring 30% of companies that comprise the bottom 40% of the remaining eligible U.S. Quality Growth Index family constituent universe after the exclusion of the 500 largest companies by market capitalization. Additional detail about the Indexs constituent eligibility criteria is included under the Additional Information About the Funds Investment Strategies section of the Prospectus. From the initial selection universe, the Index selects U.S. companies with the highest composite scores based on two fundamental factors, growth and quality, which are equally weighted. The growth factor is determined by a companys ranking based on a 40% trailing three-year sales growth, 40% trailing three-year earnings growth, and 20% earnings growth forecast. The quality factor is determined by a companys ranking based on a 50% weight to each of its trailing three-year average return on equity and its trailing three-year return on assets. Companies are ranked based on the Composite Score with the top 30% of companies selected for inclusion in the Index. The selected companies are weighted within the Index using a market capitalization weighting. The Index is based on a rules-based methodology overseen and implemented by the Quality Growth Index Committee. The Index is reconstituted and rebalanced semi-annually. To be eligible for inclusion in the Index, a company must meet the following key criteria as of the screening date: (i) be monitored by the Indexs third-party index calculation agent, (ii) list shares on a U.S. stock exchange, (iii) conduct its Primary Business Activities in the United States, (iv) have a market capitalization of at least $100 million, and (v) have a median daily dollar trading volume of at least $1 million for each of the preceding three months. For the Index, Primary Business Activities generally is determined based on the country of organization or incorporation and the country in which a companys headquarters is located, but may also consider the country to which a company has the greatest risk exposure and the country from which a company generates the most significant portion of its revenue or to which it allocates the greatest resources. At the time of each semi-annual rebalance, the weight of any individual constituent is capped at 5%. As of June 30, 2025, the Index had a market capitalization range from $83.4 million to $12.7 billion, with an average market capitalization of $2.1 billion. The Index is expected to consist of between 300 and 500 constituent companies. WisdomTree, Inc. (WisdomTree), the Index Provider and parent company of WisdomTree Asset Management, Inc. (WisdomTree Asset Management or the Adviser), currently uses the Global Industry Classification Standard (GICS ), a widely recognized industry classification methodology developed by MSCI, Inc. and Standard & Poors Financial Services LLC, to identify the extent of the Indexs exposure to a sector or industry. A GICS sector typically is composed of multiple industries. Because the Fund seeks to track the Index, it is expected to have the same sector and industry exposure as the Index. While the Indexs and the Funds sector exposure may vary from time to time, as of June 30, 2025, the Index, and, therefore, the Fund, had significant exposure ( e.g. , approximately 15% or more of the Indexs total weight) to the Industrials, Consumer Discretionary, and Information Technology Sectors. To the extent the Index is concentrated in the securities of companies assigned to a particular industry or group of related industries, the Fund will seek to concentrate its investments ( i.e. , invest more than 25% of its assets) in such industry or group of related industries to approximately the same extent as the Index.
