Strategy

FUND STRATEGY

The Fund seeks long-term capital growth by investing primarily in U.S. large-cap equity securities and diversifying across a broad range of market sectors. It employs a valuation conscious approach, one that focuses on the quality and price of individual securities, while following a research-based investment strategy to select stocks with above average growth potential.


MANAGER'S PERSPECTIVE

"We've designed this 'best ideas' fund to tap the expertise of Pioneer's industry and sector analysts. Detailed financial models, rigorous fundamental research, and valuation judgments drive stock selection while the portfolio is kept sector-neutral to the S&P 500 Index. Managers then choose securities that are highly ranked by the research team and selling at reasonable prices or substantial discounts to their underlying values."

A WORD ABOUT RISK

At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.
