C000032852 Investment Objective and Strategy
Columbia Select Mid Cap Growth Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Columbia Funds Series Trust I.
Investment objective
Columbia Mid Cap Growth Fund (the Fund) seeks significant capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index.
Principal investment strategy
Under normal circumstances, the Fund invests at least 80% of its net assets (including the amount of any borrowings for investment purposes) in equity securities (including, but not limited to, common stocks, preferred stocks and securities convertible into common or preferred stocks) of companies that have market capitalizations in the range of the companies in the Russell Midcap Index (the Index) at the time of purchase (between $378 million and $35.08 billion as of November 30, 2017). The market capitalization range and composition of the companies in the Index are subject to change. The Fund invests typically in common stocks of companies believed to have the potential for long-term, above-average earnings growth but may invest in companies for their short, medium or long-term prospects.
The Fund may from time to time emphasize one or more sectors in selecting its investments, including the consumer discretionary sector and information technology sector. The Fund may invest up to 20% of its total assets in foreign securities. The Fund may invest directly in foreign securities or indirectly through depositary receipts. The Fund may invest in special situations, such as companies involved in initial public offerings, tender offers, mergers and other corporate restructurings, and in companies involved in management changes or companies developing new technologies. The Funds investment strategy may involve the frequent trading of portfolio securities.
