PMSBX Investment Objective and Strategy
MidCap Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Principal Funds, Inc..
Investment objective
The Fund seeks long-term growth of capital.
Principal investment strategy
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies with medium market capitalizations at the time of purchase. For this Fund, companies with medium market capitalizations are those with market capitalizations within the range of companies comprising the Russell Midcap Index (as of December 31, 2017 , this range was between approximately $1.1 billion and $36.7 billion ). The Fund also invests in foreign securities. The Fund invests in equity securities with growth and/or value characteristics. Investing in value equity securities is an investment strategy that emphasizes buying equity securities that appear to be undervalued. The growth orientation selection emphasizes buying equity securities of companies whose potential for growth of capital and earnings is expected to be above average.
The Fund does not have a policy of preferring one of these categories over the other.
