KLGRX Investment Objective and Strategy
MainStay MacKay Growth Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by New York Life Investments Funds Trust.
Investment objective
The Fund seeks long-term growth of capital.
Principal investment strategy
The Fund normally invests at least 80% of its assets in common stocks of large capitalization growth companies with market capitalizations that, at the time of investment, are similar to companies in the Russell 1000 Growth Index (which ranged from $653.7 million to $867.5 billion as of December 31, 2017). Investment Process: Using an objective, disciplined and broadly-applied process, MacKay Shields LLC, the Fund's Subadvisor, selects large capitalization securities that it believes have the most potential to appreciate, while seeking to limit exposure to risk. The Subadvisor also seeks to control the Fund's exposure to risk by seeking to construct a broadly-diversified portfolio of securities issued by companies, across sectors and industries using quantitative analysis to identify undervalued securities.
The Subadvisor uses a quantitative model that is designed to evaluate individual issuers and securities across multiple criteria, including valuation, momentum and market sentiment. The Subadvisor also conducts a qualitative review of the results of the quantitative analysis. In certain cases, the Subadvisor may deviate from positions or weightings suggested by the quantitative analysis to account for events and conditions that may not be quantifiable by the analysis, such as company-specific and market events. The Subadvisor evaluates the quantitative model and, from time to time, the Subadvisor may adjust the metrics and data underlying its quantitative analysis or model for a variety of reasons, including, without limitation, to account for changing market, financial or economic conditions.
The Subadvisor may sell a security if, among other reasons, it no longer believes the security will contribute to meeting the investment objective of the Fund, if better opportunities are identified, or if it determines the initial investment expectations are not being met.
