C000166827 Investment Objective and Strategy
MainStay VP MacKay Small Cap Core Portfolio describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Mainstay Vp Funds Trust.
Investment objective
The Portfolio seeks long-term growth of capital.
Principal investment strategy
"The Portfolio invests, under normal circumstances, at least 80% of its assets (net assets plus any borrowings for investment purposes) in the securities of U.S. companies with market capitalizations at the time of investment that are similar to the Russell 2000 Index (which ranged from $7.0 million to $43.6 billion as of February 28, 2026). An issuer of a security is considered to be a U.S. or foreign issuer based on the issuer's ""country of risk"" (or similar designation) as determined by a third-party such as Bloomberg. Investment Process: Wellington Management Company LLP, the Portfolios Subadvisor (the Subadvisor), seeks to achieve the Portfolios investment objective by allocating the Portfolios assets among multiple internal portfolio management teams that employ investment strategies with different investment styles, including, Small Cap Value Opportunities, Select Small Cap Growth and Small Companies Strategies.
Each investment strategy has distinct investment philosophies and analytical processes to identify securities for purchase or sale. Collectively, the investment styles represent a range of investment philosophies, companies, and industries. To better assess strategic business issues that impact the performance of a company, the underlying portfolio management teams may also give consideration to financially material environmental, social and/or governance (ESG) factors. The underlying portfolio management teams have discretion to determine the materiality of, as well as the level at which, financially relevant ESG factors are imbedded into its overall fundamental analysis when making an investment decision. Small Cap Value Opportunities Strategy: The Subadvisors Small Cap Value Opportunities team seeks to invest in quality companies at a substantial discount that often arises when the market is concerned about the companies future.
The Small Cap Value Opportunities team believes those concerns can become mispriced due to the presence of biases or change and that research specifically focused on identifying signs of biases and change allows the Small Cap Value Opportunities team to identify mispriced stocks. Change can include secular or cyclical shifts, changes in industry structure, changes in management, or significant shifts in the return on (and of) capital, balance sheet and cash flows. Biases include anchoring (relying too heavily on the first piece of information) and availability (relying on examples that immediately come to mind). The Small Cap Value Opportunities team seeks to maximize a combination of valuation, capital returns, and quality. Select Small Cap Growth Strategy: The Subadvisors Select Small Cap Growth team focuses on identifying investment opportunities in emerging and re-emerging growth companies.
Emerging growth companies are companies that are poised to accelerate top-line and / or bottom-line growth, and re-emerging growth companies are companies that are approaching a return to rapid growth. The Select Small Cap Growth team believes the typical profile of an emerging growth company is one that offers disruptive technologies, innovative business models, or is in a rapidly growing market segment. The Select Small Cap Growth team believes that re-emerging growth companies are typically experiencing turnarounds or management changes or are in cyclical industries. Small Companies Strategy: The Subadvisors Small Companies team seeks to construct a broadly diversified portfolio across sectors and industries using fundamental analysis to identify a universe of undervalued and overvalued securities.
The Small Companies team employs a traditional, bottom-up fundamental research approach to identify securities with potential positive inflections in business momentum (i.e., whether a companys share price is trending up or down) that the Small Companies team believes have the most potential to appreciate, while seeking to limit exposure to risk. The Small Companies team also seeks to minimize exposure to risk by diversifying investments over securities issued by a large number of companies across various industries and sectors. Other Strategies: New York Life Investment Management LLC and/or the Subadvisor may modify the strategies summarized above and allocate the Portfolios assets among or to other strategies, such as event-driven, economic sector, or valuation measures, developed or implemented based on, among other factors, changing market conditions."
