FUND STRATEGY
INVESTMENT STYLE
The Fund seeks reasonable income and capital growth by investing primarily in the equity securities of U.S.
companies. The Fund diversifies across all sectors of the S&P 500® Index using an actively managed, bottomup approach that seeks under-valued, high quality stocks of well established companies in well established
businesses.

Call 1-800-622-9876 or visit us.pioneerinvestments.com for the most recent month-end performance results. Current
performance may be lower or higher than the performance data quoted. The performance data quoted represents past
performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when
redeemed, may be worth more or less than their original cost.
Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers, fund
performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified
period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information.

Public Offering Price reflects deduction of maximum 5.75% sales charge.
All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for
which performance and expenses will differ.
Performance for periods prior to the inception of Class Y shares reflects the NAV performance of the Fund’s Class A Shares. The
performance does not reflect differences in expenses, including the 12b-1 fees applicable to Class A Shares. Since fees for
Class A shares are generally higher than those of Class Y, the performance shown for the Class Y shares prior to their inception
would have been higher. Class Y shares are not subject to sales charges and are available for limited groups of investors,
including institutional investors.

NAV results represent the percent change in net asset value per share. Returns would have been lower had sales charges been
reflected. The Lipper Large-Cap Core Funds Average represents the average annual returns for all Large-Cap Core Funds for the
respective time periods. The Standard & Poor’s 500 Stock Index (the S&P 500) is a commonly used measure of the broad U.S.
stock market. Indices are unmanaged and their returns assume reinvestment of dividends, and unlike Fund returns, do not
reflect any fees or expenses. You cannot invest directly in an index. Periods less than one year are actual, not annualized.
