C000021428 Investment Objective and Strategy
ON S&P MidCap 400® Index Portfolio describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Ohio National Fund INC.
Investment objective
Seeks total return approximating that of the Standard & Poor's MidCap 400 Index (the Index) including reinvestment of dividends, at a risk level consistent with that of the Index.
Principal investment strategy
Under normal circumstances, the Portfolio invests more than 80% of its net assets (plus borrowings for investment purposes, if any) in the common stocks and other securities that are included in the Index. In seeking to track the Index, the Adviser and sub-adviser attempt to allocate the Portfolios investments among stocks in approximately the same weightings as the Index. The Portfolio is rebalanced periodically to reflect changes in the Index. The Portfolio may buy and sell Index futures contracts in furtherance of its strategy. The Portfolio attempts to replicate the performance of the Index. However, Portfolio expenses reduce the Portfolios ability to exactly track the Index. There can be no assurance that the Portfolios investments will have the desired effect. The Portfolio may not always hold the same securities as the Index and therefore statistical sampling techniques may be used to attempt to track the returns of the Index.
The Indexs stock weighting is by market capitalization (i.e. size). Rebalancing is set by the Index vendor, which tends to be quarterly. The Portfolio attempts to hold approximately the same number of stocks as are in the Index. The market capitalization of the index as of March 31, 2026 ranged from $1.27 billion to $27.12 billion. Prior to December 19, 2016, the Portfolio was known as the Target VIP Portfolio and was managed by First Trust Advisors L.P.
