C000004635 Investment Objective and Strategy
JNL/Mellon Capital S&P 400 MidCap Index 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 (Fund or Feeder Fund) is to track the performance of the S&P MidCap 400 Index to provide long-term capital growth by investing in equity securities of medium capitalization-weighted domestic corporations through exclusive investment in shares of the JNL Mid Cap Index Fund (Master Fund).
Principal investment strategy
The Fund operates as a feeder fund and seeks to achieve its goal by investing all of its assets in Class I shares of the Master Fund. The Master Fund invests, under normal circumstances, at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes) in the stocks in the S&P MidCap 400 Index (Index) in proportion to their market capitalization weighting in the Index. The Master Fund employs a passive investment approach, called indexing, which attempts to replicate the investment performance of the Index through representative sampling. The Master Fund does not employ traditional methods of active investment management, which involves the buying and selling of securities based upon security analysis. The Master Fund attempts to replicate the Index by investing all or substantially all of its assets in the stocks that make up the Index.
As of December 31, 2025, the market capitalization range of the Index is $1.2 billion to $33.6 billion. Indexing may offer a cost-effective investment approach to gaining diversified market exposure over the long term. When attempting to replicate a capitalization-weighted index such as the Index, portfolio turnover is reduced to what the index adds and deletes, contract owner contributions and withdrawals, and reinvestment of income. The replicated portfolio does not require rebalancing as a result of market movement. It is rebalanced automatically with the change in share prices of the securities owned. The Master Funds holdings are rebalanced on a regular basis to reflect changes in the composition of the Index. The Master Fund may also invest in a combination of exchange-traded funds (ETFs) and cash to maintain correlation to its index, to assist with index rebalances, and to meet redemption or purchase requests.
The Master Fund may invest in financial futures, a type of derivative that may be used to obtain exposure to a variety of underlying assets, to provide liquidity for cash flows, to hedge dividend accruals or for other purposes that facilitate meeting the Master Funds objective. The Master Funds use of financial futures is intended to assist replicating the investment performance of the Index.
