C000027836 Investment Objective and Strategy
William Blair Mid Cap Growth Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by William Blair Funds.
Investment objective
The William Blair Mid Cap Growth Fund seeks long-term capital appreciation.
Principal investment strategy
Under normal market conditions, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in stocks of medium capitalized (mid cap) companies. The Fund invests primarily in a diversified portfolio of equity securities, including common stocks and other forms of equity investments (e.g., securities convertible into common stocks), of mid cap domestic growth companies that are expected to exhibit quality growth characteristics. For purposes of the Fund, the Adviser considers a company to be a mid cap company if it has a market capitalization no smaller than the smallest capitalized company, and no larger than the largest capitalized company, included in the Russell Midcap Index at the time of the Funds investment. Securities of companies whose market capitalizations no longer meet this definition after purchase may continue to be held in the Fund.
To a limited extent, the Fund may also purchase stocks of companies with business characteristics and growth prospects similar to mid cap companies, but that may have market capitalizations above the market capitalization of the largest member, or below the market capitalization of the smallest member, of the Russell Midcap Index. The Russell Midcap Index measures the performance of the 800 companies with the lowest market capitalizations in the Russell 1000 Index. The companies in the Russell Midcap Index are considered representative of mid cap companies. The size of companies in the Russell Midcap Index may change with market conditions. In addition, changes to the composition of the Russell Midcap Index can change the market capitalization range of companies included in the index. As of June 23, 2017, the Russell Midcap Index included securities issued by companies that ranged in size between $65 million and $92 billion.
In choosing investments, the Adviser performs fundamental company analysis and focuses on stock selection. The Adviser evaluates the extent to which a company meets the quality growth criteria set forth below. All of the criteria are evaluated relative to the valuation of the security. The weight given to a particular investment criterion will depend upon the circumstances, and Fund holdings may not meet all of the following criteria: (a) the company should be, or should have the expectation of becoming, a significant provider in the primary markets it serves, (b) the company should have some distinctive attribute relative to present or potential competitors (for example, this may take the form of proprietary products or processes, a unique distribution system, an entrenched brand name or an especially strong financial position relative to its competition), (c) the company should participate in an industry expected to grow rapidly due to economic factors or technological change or should grow through market share gains in its industry and (d) the company should have a strong management team.
