C000021423 Investment Objective and Strategy
ON Bryton Growth Portfolio describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Ohio National Fund INC.
Investment objective
Seeks long-term growth of capital.
Principal investment strategy
The Portfolio invests primarily in common stocks of small capitalization growth companies. Under normal circumstances, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes, if any) in stocks of small capitalization companies (that is, those with a market capitalization at the time of investment that is no greater than the largest market capitalization of a company in the Russell 2000 Index for the previous 12 months). The Portfolio is actively managed by BlackRock Investment Management, LLC (BlackRock) under a sub-advisory agreement with the Adviser. BlackRock began managing the Portfolio in February 2019. BlackRock seeks to pursue the Portfolios investment objective by investing primarily in common stock, focusing on small capitalization companies that BlackRock believes have above average prospects for earnings growth.
BlackRock invests in a disciplined manner, by using proprietary return forecast models that incorporate quantitative analysis. These forecast models are designed to identify aspects of mispricing across stocks that the Portfolio can seek to capture by over- and under-weighting particular equities while seeking to control incremental risk. BlackRock then constructs and rebalances the Portfolio by integrating its investment insights with the model-based optimization process. BlackRock has no stated minimum holding period for investments and may buy or sell securities whenever it sees an appropriate opportunity. The Portfolio may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies. The portfolio managers consider a variety of factors in determining whether to sell a security, including changes in market conditions, changes in prospects for the security, alternative investment possibilities and other factors they believe to be relevant.
