C000004657 Investment Objective and Strategy
JNL/T. Rowe Price Mid-Cap Growth Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by JNL Series Trust.
Investment objective
The investment objective of the Fund is long-term growth of capital.
Principal investment strategy
The Fund seeks to achieve its objective by investing at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes), under normal circumstances, in a broadly diversified portfolio of common stocks of medium-sized (mid-capitalization) companies whose earnings T. Rowe Price Associates, Inc., the Funds sub-adviser (Sub-Adviser), expects to grow at a faster rate than the average company. The Sub-Adviser defines mid-capitalization companies as those whose market capitalization, at the time of acquisition by the Fund, falls within the capitalization range of companies (i) in the Russell MidCap Growth Index; or (ii) represented in a third-party growth-oriented index and the companys market capitalization falls within the market capitalization range of companies in the Russell Midcap Index, MSCI USA Mid Cap Index, or MSCI World Mid Cap Index (after systematically removing any companies that cannot reasonably be considered a mid-cap company from the high and low ends of the range of each index).
The market capitalization of companies in the Funds portfolio, the Russell MidCap Growth Index, the Russell Midcap Index, the MSCI USA Mid Cap Index, or the MSCI World Mid Cap Index change over time. As of December 31, 2025, the market capitalization range for the Russell MidCap Growth Index was $1.2 billion to $88.9 billion. As of December 31, 2025, the market capitalization range represented across the Russell Midcap Index, MSCI USA Mid Cap Index, and MSCI World Mid Cap Index (after removing any outlier companies) was $1.8 billion to $98 billion. The Fund may at times invest significantly in the same economic sector. In addition, the Fund has the flexibility to purchase stock of some larger and smaller companies that have qualities consistent with the portfolios core characteristics. The Fund may also invest up to 25% of its total assets, (excluding reserves) in foreign securities, including securities and instruments that are economically tied to emerging markets, and 10% of its assets in futures.
The Fund's investments may include holdings in companies that only recently began to trade publicly.
