President's Letter

Dear Shareowner,

Stock and bond markets around the globe this year have experienced one of their
most tumultuous periods in history. Investors have witnessed volatility of a
magnitude that many have never before seen. Distance often provides the best
vantage point for perspective. Still, we believe that the benefits of basic
investment principles that have stood the test of time -- even in the midst of
market turmoil -- cannot be underestimated.

First, invest for the long term. The founder of Pioneer Investments, Philip L.
Carret, began his investment career during the 1920's. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme economic slumps can create opportunities for purchase. Indeed, many of
our portfolio managers, who follow the value-conscious investing approach of
our founder, are looking at recent market conditions as an opportunity to buy
companies whose shares we believe have been unjustifiably beaten down by
indiscriminate selling, but we have identified as having strong prospects over
time. While investors may be facing a sustained market downturn, we continue to
believe that patience, along with staying invested in the market, are important
considerations for long-term investors.

A second principle is to stay diversified across different types of
investments. The global scope of the current market weakness poses challenges
for this basic investment axiom. But the turbulence makes now a good time to
reassess your portfolio and make sure that your investments continue to meet
your needs. We believe you should work closely with your financial advisor to
find the mix of stocks, bonds and money market assets that is best aligned to
your particular risk tolerance and investment objective.

As the investment markets sort through the continuing crisis in the financial
industry, we are staying focused on the fundamentals and risk management. With
more than 80 years of experience behind us, we have learned how to navigate
turbulent markets. At Pioneer Investments, risk management has always been a
critical part of our culture -- not just during periods of extraordinary
volatility. Our investment process is based on fundamental research,
quantitative analysis and active portfolio management. This three-pillared
process, which we apply to each of our portfolios, is supported by an
integrated team approach and is designed to carefully balance risk and reward.
While we

see potential chances for making money in many corners of the market, it takes
research and experience to separate solid investment opportunities from
speculation.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
www.pioneerinvestments.com. Thank you for investing with Pioneer.

Respectfully,

/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 9/30/08

In the following discussion, Rod Wright, lead portfolio manager of Pioneer
Value Fund, reviews recent market events and describes the factors that
affected Pioneer Value Fund's performance during the annual reporting period
ended September 30, 2008. Mr. Wright assumed the management duties of the Fund
on April 30, 2008.

Q    How did the U.S. stock market and Pioneer Value Fund perform during the 12
     months ended September 30, 2008?

A    U.S. equities finished the 12-month period ended September 30 deeply in the
     red, reflecting the unprecedented nature of the financial turmoil that
     characterized the latter half of the period.

     When the Fund's fiscal year began on October 1, 2007, the housing and
     subprime mortgage crisis was already several months old. Still, the
     consensus view at the time was that the difficulties would largely stay
     confined to the financial sector rather than spreading to the broader
     economy. The result was that while stock prices were generally volatile
     throughout the first half of the reporting period, by the middle of May
     2008, the major U.S. indices stood only modestly off their highs of 2007.

     As the summer of 2008 progressed, however, a stream of negative news events
     began to weigh heavily on market performance. Investors had to contend with
     the government bailouts of Fannie Mae and Freddie Mac, the failures of
     Lehman Brothers and Washington Mutual, the rescue of Merrill Lynch by Bank
     of America, and the $85 billion emergency loan to AIG by the U.S.
     government. This chain of events had two important effects. First, it led
     investors to begin anticipating a recession and a concurrent downturn in
     corporate profits. Second, it sparked a wave of forced selling by hedge
     funds and other highly leveraged investors. With these bearish factors as
     the backdrop, stocks plunged in early summer, paused for approximately two
     months, and then collapsed in September as the 12-month reporting period
     was drawing to a close. On the second-to-last day of the period, the Dow
     Jones Industrial Average registered a 778-point drop -- one of the worst
     one-day declines in the 112-year history of the index.

     In this environment, the Russell 1000 Value Index (the Russell Index), the
     Fund's benchmark, returned -23.56% during the 12-month period ended
     September 30, 2008, while Class A shares of Pioneer Value Fund
     underperformed the Russell Index by a wide margin, returning -30.75% at net
     asset value over the same period. The Fund's return also trailed the
     -23.80% average return of the 569 funds in its Lipper peer group, Large-Cap
     Value Funds, over the same 12-month period.


4    Pioneer Value Fund | Annual Report | 9/30/08


Q    What are your comments regarding the Fund's underperformance over the
     12-month period ended September 30, 2008?

A    Pioneer is extremely disappointed with the Fund's return during the past
     year. Still, we believe it is important to note that since we took over the
     management duties of the Fund on April 30 of this year, its return has been
     in line with the Russell Index, as the changes we made to the portfolio
     helped arrest the heavy underperformance the Fund experienced in the first
     seven months of the period. We discuss the changes we have made to the
     portfolio in greater detail in the pages that follow.

     Looking at the Fund's results in the first half of the 12-month period,
     prior to the portfolio management change, the primary reason why the Fund
     lagged the Russell Index was its underperformance in the health care
     sector. Positions in the large-cap pharmaceutical stocks Schering-Plough,
     Merck, and Bristol-Myers Squibb all plunged during the first half of the
     reporting period, costing the Fund over three percentage points of
     performance against the Russell Index. That drop represented more than 40%
     of the overall 7.19% shortfall versus the benchmark for the entire annual
     reporting period. The Fund continues to hold reduced positions in all three
     stocks in its portfolio, based on our belief that the companies represent
     attractive values at their lower levels.

     The financial sector also proved to be an area of difficulty for the Fund
     in the first half of the reporting period and prior to April 30th. Most
     notably, holdings in Washington Mutual (WaMu) and First Marblehead both
     plummeted amid concerns about the viability of the two companies. We sold
     both positions upon taking over management of the Fund, which enabled it to
     avoid the negative impact of WaMu's eventual bankruptcy.

Q    What changes have you made to the Fund since taking over its management on
     April 30, 2008?

A    Our primary objective has been to halt the underperformance of the Fund by
     taking three steps: first, by cutting its exposure to many of its
     underperforming positions (such as WaMu); second, by adding higher-quality
     holdings to improve the overall strength of the portfolio; and third, by
     increasing diversification to reduce risk.

     Our efforts to diversify the Fund's portfolio are based on our belief that
     the highly concentrated nature of the Fund's investments was a key factor
     in its underperformance during the first half of the reporting period.
     During the first half of the reporting period, the Fund held fewer than 40
     individual positions on average. This meant that one or two stock
     "blow-ups" could hurt the entire portfolio. We therefore altered the Fund's
     portfolio to make it more broad based, bringing its total number of
     holdings to 84 by the end of September 2008. At the same time, we took
     steps to reduce the Fund's


                               Pioneer Value Fund | Annual Report | 9/30/08    5


     risk relative to the Russell Index. While the Fund continues to emphasize
     and de-emphasize certain sectors, we are also making an effort to avoid
     putting too much of the Fund's assets into any one area of the market.

     Our new purchases for the Fund, meanwhile, have been stocks of companies
     with strong balance sheets, stable earnings power, high profit margins, and
     attractive valuations. Included in this group are Cardinal Health, Waste
     Management, Microsoft, Apache, and Applied Materials. Not all of the Fund's
     holdings have been winners, of course: we also invested the Fund in some
     stocks that have underperformed, such as the refining company Valero
     Energy. However, the fact that the Fund has performed in line with the
     Russell Index since April 30, 2008, indicates that we were largely
     successful in our objective of stabilizing its performance.

Q    Do you have any closing thoughts for investors?

A    We continue to hold a cautious outlook on U.S. equities due to the
     unprecedented nature of the financial crisis. Nevertheless, our core belief
     is that a focus on identifying the most reasonably valued, fundamentally
     sound stocks in the market should lead to outperformance in both up and
     down markets. We therefore believe that our conservative approach for the
     Fund will prove well suited not only to the difficult environment of the
     present, but also to the inevitable recovery.

returns, do not reflect any fees, expenses or sales charges. You cannot invest
directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" charts on
pages 10-13.

Call 1-800-225-6292 or visit www.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.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
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 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.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

returns reflect the deduction of applicable contingent deferred sales charge
(CDSC). Effective December 1, 2004, the period during which a CDSC is applied
to withdrawals was shortened to 5 years. The maximum CDSC for Class B shares
continues to be 4%. For more complete information, please see the prospectus
for details.

Note: Shares purchased prior to December 1, 2004 remain subject to the CDSC in
effect at the time you purchased those shares. For performance information for

Call 1-800-225-6292 or visit www.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 shown 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 Rule 12b-1 fees, applicable to
Class A shares. Since fees for Class A shares are generally higher than those
of Class Y shares, the performance for Class Y shares prior to their inception
(8/11/04) would have been higher. Class Y shares are not subject to sales
charges and are available to limited groups of eligible investors, including
institutional investors. 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 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.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.


                              Pioneer Value Fund | Annual Report | 9/30/08    13


Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Fund expenses; and

(2)  transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.


Using the Tables
- --------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.   Divide your account value by $1,000
     Example: an $8,600 account value [divided by] $1,000 = 8.6

2.   Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

Expenses Paid on a $1,000 Investment in Pioneer Value Fund

Based on actual returns from April 1, 2008 through September 30, 2008.

- -------------------------------------------------------------------------------------


*    Expenses are equal to the Fund's annualized expense ratio of 0.94%, 2.04%,
     1.91% and 0.53% for Class A, Class B, Class C, and Class Y shares,
     respectively, multiplied by the average account value over the period,
     multiplied by 183/366 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

Notes to Financial Statements | 9/30/08

1. Organization and Significant Accounting Policies

Pioneer Value Fund (the Fund), is a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is reasonable income
and capital growth.

The Fund currently offers four classes of shares designated as Class A, Class
B, Class C, and Class Y shares. As planned, Investor Class shares converted to
Class A shares on December 10, 2006. Class R shares were first publicly offered
on April 1, 2003 and ceased operations on January 31, 2007. Class Y shares were
first publicly offered on August 11, 2004. Each class of shares represents an
interest in the same portfolio of investments of the Fund and has equal rights
to voting, redemptions, dividends and liquidation, except that each class of
shares can bear different transfer agent and distribution fees and have
exclusive voting rights with respect to the distribution plans that have been
adopted by Class A, Class B, and Class C shareowners, respectively. There is no
distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gains and losses on investments during the
reporting period. Actual results could differ from those estimates.

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. The Fund's prospectuses (unaudited) contain information
regarding the Fund's principal risks. Please refer to those documents when
considering the Fund's principal risks.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:


                              Pioneer Value Fund | Annual Report | 9/30/08    33


A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities are valued at the last sale price
     on the principal exchange where they are traded. Securities that have not
     traded on the date of valuation, or securities for which sale prices are
     not generally reported, are valued at the mean between the last bid and
     asked prices. Securities for which market quotations are not readily
     available are valued at their fair values as determined by, or under the
     direction of, the Board of Trustees. Trading in foreign securities is
     substantially completed each day at various times prior to the close of the
     NYSE. The values of such securities used in computing the net asset value
     of the Fund's shares are determined as of such times. The Fund may also use
     the fair value of a security including a non-U.S. security when the closing
     market price on the principal exchange where the security is traded no
     longer reflects the value of the security. At September 30, 2008, there
     were no securities fair valued. Temporary cash investments are valued at
     cost which approximates market value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in the exercise of reasonable diligence. Interest income is recorded
     on the accrual basis. Dividend and interest income are reported net of
     unrecoverable foreign taxes withheld at the applicable country rates.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Foreign Currency Translation

     The books and records of the Fund are maintained in U.S. dollars. Amounts
     denominated in foreign currencies are translated into U.S. dollars using
     current exchange rates.

     Net realized gains and losses on foreign currency transactions, if any,
     represent, among other things, the net realized gains and losses on foreign
     currency contracts, disposition of foreign currencies and the difference
     between the amount of income accrued and the U.S. dollars actually
     received. Further, the effects of changes in foreign currency exchange
     rates on investments are not segregated in the Statement of Operations from
     the effects of changes in market price of those securities but are included
     with the net realized and unrealized gain or loss on investments.


34    Pioneer Value Fund | Annual Report | 9/30/08


C.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required. Tax
     years prior to 2004 are closed (not subject to examination by tax
     authorities) due to the expiration of statute of limitations; all other tax
     years are open.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as from or in excess of net
     investment income or as from net realized gain on investment transactions,
     or as from paid-in capital, depending on the type of book/tax differences
     that may exist.

     The Fund has elected to defer approximately $329,723,434 of capital losses
     recognized between November 1, 2007 and September 30, 2008 to its fiscal
     year ending September 30, 2009.

     At September 30, 2008, the Fund has reclassified $11,368 to increase
     undistributed net investment income and $11,368 to increase accumulated net
     realized loss on investments and foreign currency transactions, to reflect
     permanent book/tax differences. The reclassification has no impact on the
     net assets of the Fund and presents the Fund's capital accounts on a tax
     basis.

     The tax character of distributions paid during the years ended September
     30, 2008 and September 30, 2007 was as follows:




                                                          2008              2007
                                                              
     Distributions paid from:
     Ordinary income                              $125,423,328      $109,853,484
     Long-term capital gain                        210,756,777       613,642,261
     ---------------------------------------------------------------------------
       Total                                      $336,180,105      $723,495,745
     ---------------------------------------------------------------------------


     The following shows the components of distributable earnings on a federal
     income tax basis at September 30, 2008:




                                                                            2008
                                                                
     Distributable earnings:
     Undistributed ordinary income                                 $  19,126,106
     Current year post October loss deferred                        (329,723,434)
     Unrealized depreciation                                        (127,048,629)
     ---------------------------------------------------------------------------
     Total                                                         $(437,645,957)
     ---------------------------------------------------------------------------


                              Pioneer Value Fund | Annual Report | 9/30/08    35


     The difference between book-basis and tax-basis unrealized depreciation is
     attributable to the tax deferral of losses on wash sales.

D.   Forward Foreign Currency Contracts

     The Fund enters into forward foreign currency contracts (contracts) for the
     purchase or sale of a specific foreign currency at a fixed price on a
     future date as a hedge or cross-hedge against either specific investment
     transactions (settlement hedges) or portfolio positions (portfolio hedges).
     All contracts are marked to market daily at the applicable exchange rates,
     and any resulting unrealized gains or losses are recorded in the Fund's
     financial statements. The Fund records realized gains and losses at the
     time a portfolio hedge is offset by entry into a closing transaction or
     extinguished by delivery of the currency. Risks may arise upon entering
     into these contracts from the potential inability of counterparties to meet
     the terms of the contract and from unanticipated movements in the value of
     foreign currencies relative to the U.S. dollar. As of September 30, 2008,
     the Fund had no outstanding settlement or portfolio hedges.

E.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
     (UniCredit), earned $178,154 in underwriting commissions on the sale of
     Class A shares during the year ended September 30, 2008.

F.   Class Allocations

     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on the respective percentage of adjusted net assets at the beginning
     of the day.

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B, and Class C shares of the Fund,
     respectively (see Note 4). Class Y shares are not subject to a distribution
     plan. Shareowners of each class participate in all expenses and fees paid
     to the transfer agent, Pioneer Investment Management Shareholder Services,
     Inc. (PIMSS), for its services, which are allocated based on the number of
     accounts in each class and the ratable allocation of related out-of-pocket
     expenses (see Note 3).

     Distributions to shareowners are recorded as of the ex-dividend date.
     Distributions paid by the Fund with respect to each class of shares are
     calculated in the same manner, at the same time, and in the same amount,
     except that Class A, Class B, Class C and Class Y shares can bear different
     transfer agent and distribution expense rates.


36    Pioneer Value Fund | Annual Report | 9/30/08


G.   Repurchase Agreements

     With respect to repurchase agreements entered into by the Fund, the value
     of the underlying securities (collateral), including accrued interest
     received from counterparties, is required to be at least equal to or in
     excess of the value of the repurchase agreement at the time of purchase.
     The collateral for all repurchase agreements is held in safekeeping in the
     customer-only account of the Fund's custodian or subcustodians. The Fund's
     investment adviser, Pioneer Investment Management, Inc. (PIM), is
     responsible for determining that the value of the collateral remains at
     least equal to the repurchase price.

H.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors. When entering into a loan, the Fund receives
     collateral and earns income in the form of negotiated lenders' fees. The
     Fund also continues to receive interest or payments in lieu of dividends on
     the securities loaned. Gain or loss on the fair value of the loaned
     securities that may occur during the term of the loan will be for the
     account of the Fund. The loans are secured by collateral which is required
     to be at least 102%, at all times, of the fair value of the securities
     loaned. The amount of collateral is required to be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. The
     Fund has the right under the lending agreement to recover the securities
     from the borrower on demand. The Fund invests cash collateral in cash
     equivalent investments. Securities lending collateral is managed by Credit
     Suisse.

I.   Option Writing

     When the Fund writes an option, an amount equal to the premium received by
     the Fund is recorded as a liability and is subsequently adjusted to the
     current fair value of the option written. Premiums received from writing
     options that expire unexercised are treated by the Fund on the expiration
     date as realized gains from investments. The difference between the premium
     and the amount paid on effecting a closing purchase transaction, including
     brokerage commissions, is also treated as a realized gain, or, if the
     premium is less than the amount paid for the closing purchase transaction,
     as a realized loss. If a call option is exercised, the premium is added to
     the proceeds from the sale of the underlying security in determining
     whether the Fund has realized a gain or loss. The Fund as writer of an
     option bears the market risk of an unfavorable change in the price of the
     security underlying the written option.


                              Pioneer Value Fund | Annual Report | 9/30/08    37


     Transactions in written call options for the year ended September 30, 2008
     are summarized as follows:

     ---------------------------------------------------------------------------


2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. PIM receives a basic fee that is calculated at the annual rate of
0.60% of the Fund's average daily net assets up to $5 billion, 0.575% on the
next $5 billion and 0.55% on the excess over $10 billion. The basic fee is
subject to a performance adjustment (limited to a maximum of -0.10% applied to
average assets during the measurement period) based on the Fund's investment
performance as compared with the Russell 1000[RegTM] Value Index over a rolling
36-month period. In addition, the fee is further limited to a maximum
annualized rate adjustment of up to 0.10% (a "ceiling") applied to average
assets during the current month. For the year ended September 30, 2008, the
aggregate performance adjustment resulted in a decrease to the basic fee of
$3,776,033. For the year ended September 30, 2008, the effective management fee
was equivalent to 0.47% of the Fund's average daily net assets.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $19,675 in management fees,
administrative costs and certain other services payable to PIM at September 30,
2008.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $353,502 in transfer agent fees payable to PIMSS at September
30, 2008.

4. Distribution Plan

The Fund adopted a Plan of Distribution with respect to Class A, Class B and
Class C shares (Class A Plan, Class B Plan, Class C Plan) in accordance with
Rule 12b-1 of the Investment Company Act of 1940. Effective February 1, 2008,
under the Class A Plan, the Fund pays PFD a service fee equal to 0.25% of the


38    Pioneer Value Fund | Annual Report | 9/30/08


average daily net assets attributable to Class A shares to finance activities
primarily intended to result in the sale of Class A shares. Prior to February
1, 2008, PFD was reimbursed for service fees in an amount up to 0.25% of the
average daily net assets attributable to Class A shares. Pursuant to the Class
B Plan and Class C Plan the Fund pays PFD 1.00% of the average daily net assets
attributable to each class of shares. The fee consists of a 0.25% service fee
and a 0.75% distribution fee paid as compensation for personal services and/or
account maintenance services or distribution services with regard to Class B
and Class C shares. Included in "Due to affiliates" reflected on the Statement
of Assets and Liabilities is $14,105 in distribution fees payable to PFD at
September 30, 2008.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase. Class B shares that are redeemed within five
years of purchase are subject to a CDSC at declining rates beginning at 4.00%,
based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended September
30, 2008, CDSCs in the amount of $52,662 were paid to PFD.

5. Expense Offset Arrangements

Effective July 15, 2005, the Fund has entered into commission recapture
arrangements with brokers with whom PIM places trades on behalf of the Fund
where they provide services to the Fund in addition to trade execution. These
services included payments of certain expenses on behalf of the Fund. For the
year ended September 30, 2008, expenses were not reduced under this agreement.
In addition, the Fund has entered into certain expense offset arrangements with
PIMSS resulting in a reduction in the Fund's total expenses due to interest
earned on cash held by PIMSS. For the year ended September 30, 2008, the Fund's
expenses were reduced by $94,412 under such arrangements.

6. Line of Credit

The Fund, along with certain others in the Pioneer Family of Funds (the Funds),
collectively participate in a $200 million committed, unsecured revolving line
of credit facility. Borrowings are used solely for temporary or emergency
purposes. The Fund may borrow up to the lesser of $200 million or the limits

7. New Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Fund's financial statement disclosures.

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities (SFAS 161), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Fund's financial statement disclosures.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareowners of
Pioneer Value Fund:
- --------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Value Fund ("the Fund"), including the schedule of investments, as of September
30, 2008, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the periods indicated
therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of September 30, 2008, by correspondence
with the custodian and brokers or by other appropriate auditing procedures
where replies from brokers were not received. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Value Fund at September 30, 2008, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
indicated therein, in conformity with U.S. generally accepted accounting
principles.

Approval of Investment Advisory Agreement (unaudited)

Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
The Trustees of the Fund, as required by law, determine annually whether to
continue the investment advisory agreement for the Fund. In connection with
their most recent consideration of the investment advisory agreement for the
Fund, the Trustees received and reviewed a substantial amount of information
provided by PIM in response to requests of the independent Trustees and their
independent legal counsel. The independent Trustees met on a number of
occasions with PIM and also separately with their independent legal counsel to
evaluate and discuss the information provided to them by PIM. At a meeting held
on November 13, 2007, based on their evaluation of the information provided by
PIM, the Trustees, including the independent Trustees voting separately,
unanimously approved the continuation of the investment advisory agreement for
another year.

At a meeting held on January 8, 2008, the Trustees considered whether an
amended and restated investment advisory agreement for the Fund should be
approved for an initial period ending December 31, 2009. The management fee to
be paid by the Fund to PIM under the amended and restated investment advisory
agreement is the same as the management fee provided in the previously approved
investment advisory agreement. Based on their evaluation of the information
provided by PIM, including the information provided by PIM in connection with
the Trustees' most recent approval of the continuation of the previous
investment advisory agreement, the Trustees, including the independent Trustees
voting separately, unanimously approved the amended and restated investment
advisory agreement. Shareholders of the Fund approved the amended and restated
investment advisory agreement at a meeting held on May 13, 2008.

In considering the amended and restated investment advisory agreement, the
Trustees considered various factors that they determined were relevant,
including the factors described below. The Trustees did not identify any single
factor as the controlling factor in determining to approve the amended and
restated investment advisory agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services that
were provided by PIM to the Fund under the previous investment advisory
agreement, and that would continue to be provided by PIM to the Fund under the
amended and restated investment advisory agreement, taking into account the
investment objective and strategy of the Fund and the information related to


44    Pioneer Value Fund | Annual Report | 9/30/08


the Fund provided to the Trustees at each quarterly meeting. The Trustees
reviewed the terms of the amended and restated investment advisory agreement.
The Trustees also reviewed PIM's investment approach for the Fund and its
research process. The Trustees considered the resources of PIM and the
personnel of PIM who provide investment management services to the Fund. They
also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provided under
the previous investment advisory agreement and that PIM would continue to
provide to the Fund under the amended and restated investment advisory
agreement and that, as administrator, PIM is responsible for the administration
of the Fund's business and other affairs. It was noted that PIM supervises and
monitors the performance of the Fund's service providers and provides the Fund
with personnel (including officers) as are necessary for the Fund's operations.
The Trustees considered the fees paid to PIM for the provision of such
services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that PIM would continue to provide to the Fund under
the amended and restated investment advisory agreement, were satisfactory and
consistent with the terms of the amended and restated investment advisory
agreement.

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
average performance of its peer group of funds as classified by Morningstar,
Inc. (Morningstar), an independent provider of investment company data, and
with the performance of the Fund's benchmark index. The Trustees considered
that the Fund's annualized total return was in the fourth quintile of its
Morningstar category for the one, three and five year periods ended June 30,
2007. (In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Fund's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees considered the recent changes in the Fund's
portfolio management team and that performance appeared to be improving and
concluded that the investment performance of the Fund was satisfactory.

Management Fee and Expenses
The Trustees considered that the management fee to be paid by the Fund to PIM
under the amended and restated investment advisory agreement would be the same
as the management fee to be paid by the Fund under the previously approved
investment advisory agreement. The Trustees considered information on the fees
and expenses of the Fund in comparison to the management fees of its peer group
of funds as classified by Morningstar and the expense


                              Pioneer Value Fund | Annual Report | 9/30/08    45


ratios of a peer group of funds selected on the basis of criteria determined by
the independent Trustees for this purpose using data provided by Strategic
Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an
independent third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2007 was in the first quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2007 was in the first quintile relative to its
Strategic Insight peer group.

The Trustees also reviewed management fees charged by PIM to its other clients
with a similar investment strategy as the Fund. The Trustees noted that in some
instances the fee rates for those clients were lower than the management fees
for the Fund and considered that, under the amended and restated investment
advisory agreement with the Fund, PIM performs additional services for the Fund
that it does not provide to those other clients, including oversight of the
Fund's other service providers, regulatory compliance and other services.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of services provided, taking
into account the fees charged by other advisers for managing comparable mutual
funds with similar strategies. The Trustees also concluded that the Fund's
expense ratio was reasonable, taking into account the size of the Fund, the
quality of services provided by PIM and the investment performance of the Fund.

Profitability
The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Fund in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Fund. The Trustees concluded that PIM's
profitability with respect to the management of the Fund was not unreasonable.


46    Pioneer Value Fund | Annual Report | 9/30/08


Economies of Scale
The Trustees considered the economies of scale with respect to the management
of the Fund, whether the Fund had appropriately benefited from any economies of
scale, and whether there was potential for realization of any further economies
of scale. The Trustees concluded that, because of the breakpoints in the
management fee schedule and the reduced fee rates above certain asset levels,
any perceived or potential economies of scale would be shared between PIM and
the Fund.

Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered that affiliates of PIM serve as the Fund's
transfer agent and distributor. The Trustees considered the receipt by PIM and
its affiliates of sales loads and payments under Rule 12b-1 plans in respect of
the Fund and the other Pioneer funds and the benefits to PIM and its affiliates
from the use of "soft" commission dollars generated by the Fund to pay for
research and brokerage services. The Trustees further considered the intangible
benefits to PIM by virtue of its relationship with the Fund and the other
Pioneer funds. The Trustees concluded that the receipt of these benefits was
reasonable in the context of the overall relationship between PIM and the Fund.

Conclusion
After consideration of the factors described above as well as other factors,
the Trustees, including all of the independent Trustees, concluded that the
terms of the amended and restated investment advisory agreement between PIM and
the Fund, including the fees payable thereunder, were fair and reasonable and
voted to approve the amended and restated investment advisory agreement for the
Fund.

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

                 firm, the scope of the Audit

- --------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

- --------------------------------------------------------------------------------


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant

Beginning with non-audit service contracts entered
into on or after May 6, 2003, the effective date of
the new SEC pre-approval rules, the Fund's audit
committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that
the services are determined to have a direct impact
on the operations or financial reporting of the
Fund.  For the years ended September 30, 2008
and 2007, there were no services provided to an
affiliate that required the Fund's audit committee
pre-approval.

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Fund and
affiliates, as previously defined, totaled
approximately $8,290 in 2008 and $7,820 in 2007.


(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

accountant's independence.

270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
