Investment objective
This Fund seeks capital appreciation.
Principal investment strategy
Principal Investment Strategies The Fund mainly invests in common stocks of U.S. companies that the Funds subadviser, Invesco Advisers, Inc. (Invesco Advisers), expects to have above-average growth rates. The Fund seeks to invest in newer companies or in more established companies that are in the early growth phase of their business cycle, which is typically marked by above-average growth rates. Under normal circumstances, the Fund invests directly or indirectly at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities of mid-cap companies. Equity securities may include common stocks, preferred stocks, securities convertible into common or preferred stock, rights, and warrants. Invesco Advisers currently considers mid-cap companies as those that have a market capitalization, at the time of purchase, within the range of market capitalizations of the issuers included in the Russell Midcap Growth Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month (as of February 28, 2026, between $1.47 billion and $106.18 billion).
This range is subject to change at any time due to market activity or changes in the composition of that index. The Fund may invest up to 20% of its net assets in companies whose market capitalizations at the time of investment are outside of that capitalization range. The Fund invests primarily in ?U.S. companies but may also purchase securities of issuers in any country, including developed countries and emerging market countries (i.e., those that are generally in the early stages of their industrial cycles). The Fund has no limits on the amount of its assets that can be invested in foreign securities, but currently does not intend to invest substantially in such securities. Foreign securities are those of issuers that are organized under the laws of a foreign country or that have a substantial portion of their operations or assets in a foreign country or countries, or that derive a substantial portion of their revenue or profits from businesses, investments or sales outside of the United States, or whose country of risk is a foreign country as determined by a third-party service provider.
The Fund may at times have significant exposure to one or more industries or sectors. The Fund may hold a portion of its assets in cash or cash equivalents. In selecting investments for the Fund, ?Invesco Advisers looks for companies with high growth potential using a bottom-up stock selection process. The bottom-up approach focuses on fundamental analysis of individual issuers before considering the impact of overall economic, market, or industry trends. This approach includes analysis of a companys financial statements and management structure and consideration of the companys operations, product development, and its industry position. Invesco Advisers currently focuses on what it believes to be high-growth companies that are characterized by industry leadership, market share growth, high caliber management teams, sustainable competitive advantages, and strong growth themes or new innovative products or services.
?Invesco Advisers monitors individual issuers for changes in the factors above, which may trigger Invesco Advisers decision to sell a security, but does not require its decision to do so. The factors considered by Invesco Advisers may vary in particular cases and may change over time. The Fund expects that it will engage in active and frequent trading and so will typically have a relatively high portfolio turnover rate.
