C000056041 Investment Objective and Strategy
Mid Cap Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Ultra Series Fund.
Investment objective
The Mid Cap Fund seeks long-term capital appreciation.
Principal investment strategy
The Fund invests generally in common stocks, securities convertible into common stocks and related equity securities of midsize companies (for this purpose, midsize is defined as those companies with market capitalizations of between $500 million and $70 billion). Under normal market conditions, the Fund will maintain at least 80% of its net assets (including borrowings for investment purposes) in such mid cap securities. The Fund may also invest up to 25% of its assets in foreign securities (including American Depositary Receipts (ADRs) and emerging market securities). As a non-principal investment strategy, the Fund may also invest in exchange traded funds (ETFs) that are registered investment companies, warrants, preferred stocks, and debt securities, including non-investment grade convertible debt securities.
The Fund generally holds 25-40 individual securities in its portfolio at any given time. This reflects the belief of the Funds investment adviser, Madison Asset Management, LLC (Madison), that your money should be invested in Madisons top investment ideas, and that focusing on Madisons best investment ideas is the best way to achieve the Funds investment objective. The Fund seeks attractive long-term returns through bottom-up security selection based on fundamental analysis in a diversified portfolio of high-quality companies with attractive valuations. These will typically be industry leading companies in niches with strong growth prospects. The Funds portfolio managers believe in selecting stocks for the Fund that show steady, sustainable growth and reasonable valuation. Madison follows a rigorous three-step process when evaluating companies pursuant to which Madison considers (1) the business model, (2) the management team, and (3) the valuation of each potential investment.
When evaluating the business model, Madison looks for sustainable competitive advantages, metrics that demonstrate relatively high levels of profitability, stable and growing earnings, and a solid balance sheet. When assessing management, Madison evaluates its operational and capital allocation track records and the nature of its accounting practices. The final step in the process is assessing the proper valuation for the company. Madison strives to purchase securities trading at a discount to their intrinsic value as determined by discounted cash flows modeling and additional valuation methodologies. Often, Madison finds companies that clear the business model and management team hurdles, but not the valuation hurdle. Those companies are monitored for inclusion at a later date when the price may be more appropriate.
Madison seeks to avoid the downside risks associated with overpriced securities. Madison may sell stocks for a number of reasons, including: (i) the price target Madison has set for the stock has been achieved or exceeded, (ii) the fundamental business prospects for the company have materially changed, or (iii) Madison finds a more attractive alternative. The Funds investment strategy reflects Madisons general Participate and Protect investment philosophy. Madisons expectation is that investors in the Fund will participate in market appreciation during bull markets and experience something less than full participation during bear markets compared with investors in portfolios holding more speculative and volatile securities; therefore, this investment philosophy is intended to represent a conservative investment strategy.
There is no assurance that Madisons expectations regarding this investment strategy will be realized. Although the Fund expects to pursue its investment objective utilizing its principal investment strategies regardless of market conditions, the Fund may invest up to 100% in cash, money market funds, and/or money market instruments. To the extent the Fund engages in this temporary defensive position, the Funds ability to achieve its investment objective may be diminished.
