Strategy. The portfolio managers look for stocks of companies they believe will increase in value over time. The portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the portfolio managers seek securities of companies whose earnings or revenues are not only growing, but growing at an accelerated pace.

The portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the portfolio managers seek securities of companies whose earnings or revenues are not only growing, but growing at an accelerated pace. This includes companies whose growth rates, although still negative, are less negative than prior periods, and companies whose growth rates are expected to accelerate. Among other variables, the portfolio managers will consider a companys valuation and profitability. Other analytical techniques include evaluating stock price momentum, as well as identifying additional signs of business improvement, such as increasing cash flows, or other indications of the relative strength of a companys business. In addition to accelerating growth and other signs of business improvement, the fund also considers companies demonstrating price strength relative to their peers. This means that the portfolio managers favor companies whose securities are the strongest performers compared to the overall market. These techniques help the portfolio managers make decisions about buying or holding the stocks of companies they believe have favorable growth prospects and selling the stocks of companies whose characteristics no longer meet their criteria. Although the portfolio managers intend to invest the funds assets primarily in U.S. securities, the fund may invest in securities of foreign companies when these securities meet the portfolio managers standards of selection. The fund may write covered calls on a portion of the funds holdings in common stock when the portfolio managers believe call premiums are attractive relative to the price of the underlying security.
