President's Letter

Dear Shareowner,

In 2010, the U.S. economy moved forward on a slow path to recovery. But with the
memory of a deep recession still lingering, businesses and consumers remained
cautious about both investing and spending. While business fundamentals showed
signs of improvement, there was still a reluctance to hire, and high
unemployment remained a problem throughout the year. Wary investors, concerned
about risk, gravitated towards cash and bonds for most of 2010, until better
economic news in the final few months of the year caused a slight shift in
investor sentiment back towards stocks, thus lifting equity returns.

Pioneer remains generally optimistic about the prospects for economic recovery.
The recovery process may occur more slowly than many would like, and may be
accompanied by short-term market swings. But our investment professionals are
finding what we believe are good opportunities to invest in both equities and
bonds.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. The strategy has generally performed well for many
investors. For instance, bond markets certainly rewarded investors for most of
2010, while equity markets barely budged, even though equity valuations were
inexpensive relative to bonds and compared with historic levels -- conditions
which represented potentially good value for long-term investors. Ultimately,
many of those long-term investors were rewarded when the equity markets finally
rallied over the last few months of 2010.

Pioneer has not changed the basic approach to investing that we have used for
more than 80 years. We remain focused on company fundamentals and risk
management. Our investment process is based on careful research into individual
companies, 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. Our experienced professionals devote themselves to the careful research
needed to identify investment opportunities in markets around the world.

Our advice, as always, is to work closely with a trusted financial advisor to
discuss your goals and work together to develop an investment strategy that
meets your individual needs. There is no single best strategy that works for
every investor.

Portfolio Management Discussion | 3/31/11

In the following discussion, John Peckham, senior vice president and portfolio
manager at Pioneer Investments, and Rod Wright, senior vice president and
portfolio manager at Pioneer Investments, review recent market events and
describe the factors that affected Pioneer Value Fund's performance during the
six months ended March 31, 2011. Mr. Peckham is responsible for the day-to-day
management of the Fund's portfolio. He is supported by Mr. Wright.

Q  Value stocks fared well over the six months ended March 31, 2011, tracking
   very closely to the performance of growth stocks over the period. What was
   the main driver of value stocks' performance during the six-month period?

A  Within the value world, energy stocks were the star performers for the six
   months ended March 31, 2011. A combination of attractive valuations as we
   ended summer 2010 and a subsequent rise in oil prices fueled a 43% rally in
   the sector.

   Energy stocks languished over the first nine months of 2010, as investors
   grew increasingly concerned about the prospects for global economic growth
   while keeping a wary eye on seemingly abundant oil supplies. Investor
   expectations began to change in the late summer of 2010, as the Federal
   Reserve Board (the Fed) tipped its hand and made it clear that its second
   round of quantitative easing ("QE2") would launch no later than November.

   Energy stocks benefited from QE2 in two ways. First, easy money relaxed
   investors' concerns about a slowdown in global growth and slackening demand
   for oil. Second, the Fed program pushed the U.S. dollar lower, an important
   factor in rising oil prices.

   Not surprisingly, the prospects for increased oil demand and rising oil
   prices fueled a big jump in energy stocks. Exploration & production and
   integrated oil companies were the immediate beneficiaries of higher oil
   prices. As the prospects for those companies improved, oil service,
   equipment and drilling stocks began to perk up as investors concluded the
   oil companies would ramp up spending.

   While QE2 fueled the first rally in oil prices, unrest in the Middle East
   and Northern Africa and, to a lesser degree, the tragic natural disaster in
   Japan, fueled the second leg up.


4    Pioneer Value Fund | Semiannual Report | 3/31/11


   While conditions in the Middle East and Northern Africa had begun to cool
   by the end of March 2011, the pot was still simmering in several countries
   and boiling over in Libya. Instability in the region will likely put a
   floor under oil prices in the near term.

   In contrast, Japan's impact on oil prices will almost certainly be
   short-lived, as the fuel most likely to replace nuclear energy for
   electricity generation is natural gas.

   Even after a strong run over the past six months, we think that the
   prospects for energy stocks remain promising. The weak dollar and Middle
   East unrest should support oil prices, while oil demand should continue to
   grow, driven by the emerging markets. Importantly, energy stocks in general
   appear attractively priced.

Q  How did the Fund perform in that environment over the six months ended March
   31, 2011?

A  Pioneer Value Fund Class A shares returned 17.37% at net asset value over the
   six months ended March 31, 2011, while the Fund's benchmark, the Russell 1000
   Value Index, returned 17.68%. Over the same period, the average return of the
   529 mutual funds in Lipper's Large Cap Value Fund category was 17.09%.

Q  The Fund's performance over the six months ended March 31, 2011, tracked very
   closely to that of the Fund's benchmark, the Russell 1000 Value Index. Could
   you highlight some of the factors behind the Fund's benchmark-relative
   performance?

A  Over the six months ended March 31, 2011, our sector calls for the Fund were
   very good, but they were overshadowed by some poor stock calls and a very
   modest drag from the Fund's cash position.

   Sector allocation was the primary positive contributor to the Fund's
   performance over the six-month period. In the fall of 2010, we made the
   decision to overweight the Fund to cyclical sectors, including energy,
   industrials, consumer discretionary and technology, and to underweight
   non-cyclical sectors, including health care and consumer staples.

   Two factors drove the success of our sector allocation calls in the Fund.
   First, we had valuation on our side, particularly in the energy sector.
   Second, the Fund caught a meaningful macroeconomic tailwind as QE2 lifted
   demand and drove asset prices higher. Cyclical stocks were the primary
   beneficiaries of those tailwinds. In contrast, non-cyclicals lagged over the
   six-month period.

   Overall, security selection was a drag on Fund performance during the past
   six months. While our stock picks in industrials and technology were quite


                           Pioneer Value Fund | Semiannual Report | 3/31/11    5


   good and provided a meaningful, positive contribution to Fund performance,
   stock picks in health care and financials were generally poor and detracted
   from performance.

Q  What sector allocations or portfolio holdings contributed most to the Fund's
   performance during the six-month period ended March 31, 2011?

A  Our decision to overweight the Fund to energy had the greatest positive
   effect on performance over the past six months. Not surprisingly, the top
   three contributors to the Fund's performance held in the portfolio were
   energy stocks. Oil equipment company National Oilwell Varco rose by 72%
   during the period, as drilling rig orders increased substantially. Marathon
   Oil jumped by 63% after the company announced its intention to split into two
   companies. And ConocoPhillips climbed by 42%, as the company continued to
   execute its multi-year restructuring program.

Q  Which sector allocations or portfolio holdings were drags on the Fund's
   performance during the six-month period ended March 31, 2011?

A  The Fund's holdings in financials struggled over the past six months, as
   sector allocation and security selection were quite poor. Regarding the
   former, the Fund was underweight financials during a short period of strong
   sector performance at the end of 2010 and beginning of 2011. We then moved
   the Fund to a modest overweight in financials just in time to catch a down
   draft in banks and brokers. We expect to maintain a modest overweight in
   financials in the Fund's portfolio, as valuations remain cheap, and we fully
   expect that return on equity (ROEs) and earnings will recover over time.

   Not surprisingly, several of the Fund's worst-performing stocks were in the
   financials sector. Bank of America continued to struggle with its mortgage
   woes. Comerica announced an acquisition that was poorly received by
   investors. And Goldman Sachs struggled to find its way in the post-
   regulatory reform era.

   On the positive side, JPMorgan and Wells Fargo were among the Fund's top 10
   positive contributors during the six months ended March 31, 2011.

Q  What is your outlook for 2011?

A  We remain optimistic. Equity valuations remain reasonable and the global
   economy continues to expand.

   The most important near-term economic factor is job creation: a meaningful
   improvement would cure many ills and almost certainly push the market
   higher. While the job market has improved modestly, we believe there must
   be a significant increase in small business formation and hiring to drive
   better employment statistics.


6    Pioneer Value Fund | Semiannual Report | 3/31/11


   We expect to maintain the Fund's cyclical bias, as we believe sectors such
   as energy and industrials will continue to benefit from the global
   expansion. Our stock picks for the Fund will continue to emphasize cheap
   names with what appear to be high and sustainable returns on capital, and
   cheap names that we believe have the prospects for a meaningful improvement
   in returns within a reasonable time period. We expect to maintain a bias
   toward multinational companies and dividend payers.

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

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 on
August 11, 2004, reflects the NAV performance of the Fund's Class A shares. The
performance does not reflect differences in expenses, including 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 would have been higher than the performance shown. 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

shares.


                          Pioneer Value Fund | Semiannual Report | 3/31/11    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 are equal to the Fund's annualized expense ratio of 0.99%, 2.45%,
   2.05% and 0.58% for Class A, Class B, Class C and Class Y shares,
   respectively, multiplied by the average account value over the period,
   multiplied by 182/365 (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 funds.

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 | 3/31/11 (unaudited)

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 offers four classes of shares designated as Class A, Class B, Class C,
and Class Y shares. Effective as of the close of business on December 31, 2009,
Class B shares are no longer offered to new or existing shareholders, except
that dividends and/or capital gain distributions may continue to be reinvested
in Class B shares, and shareholders may exchange their Class B shares for Class
B shares of other Pioneer funds, as permitted by existing exchange privileges.
Each class of shares represents an interest in the same portfolio of investments
of the Fund and has identical rights (based on relative net asset values) to
assets and liquidation proceeds. Share classes can bear different rates of
class-specific fees and expenses such as transfer agent and distribution fees.
Differences in class-specific fees and expenses will result in differences in
net investment income and, therefore, the payment of different dividends from
net investment income earned by each class. The Amended and Restated Declaration
of Trust of the Fund gives the Board the flexibility to specify either per-share
voting or dollar-weighted voting when submitting matters for shareholder
approval. Under per-share voting, each share of a class of the Fund is entitled
to one vote. Under dollar-weighted voting, a shareholder's voting power is
determined not by the number of shares owned, but by the dollar value of the
shares on the record date. Each share class has exclusive voting rights with
respect to matters affecting only that class, including with respect to the
distribution plan for that class. There is no distribution plan for Class Y
shares. Class B shares convert to Class A shares approximately eight years after
the date of purchase.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making the Fund more susceptible to
any economic, political, or regulatory developments or other risks affecting
those industries and sectors. The Fund's prospectus contains unaudited
information regarding the Fund's principal risks. Please refer to that document
when considering the Fund's principal risks.

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



                          Pioneer Value Fund | Semiannual Report | 3/31/11    31


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.

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:


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 that have traded on an exchange 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 available, generally are valued at the mean between
   the last bid and asked prices. Securities for which market prices and/or
   quotations are not readily available or are considered to be unreliable are
   valued using fair value methods pursuant to procedures adopted by 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 use fair value methods if it is determined that a significant
   event has occurred after the close of the exchange or market on which the
   security trades and prior to the determination of the Fund's net asset value.
   Thus, the valuation of the Fund's securities may differ from exchange prices.

   At March 31, 2011, there were no securities that were valued using fair value
   methods (other than securities that were valued using prices supplied by
   independent pricing services). Inputs used when applying fair value methods
   to value a security may include credit ratings, the financial condition of
   the company, current market conditions and comparable securities. Short-term
   fixed income securities with remaining maturities of sixty days or less
   generally are valued at amortized cost. Money market mutual funds are valued
   at net asset 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.


32    Pioneer Value Fund | Semiannual Report | 3/31/11


   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.


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 for the prior three fiscal years are subject to examination by tax
   authorities.

   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 tax character of current year distributions payable will be determined at
   the end of the current taxable year. The tax character of distributions paid
   during the year ended September 30, 2010 was as follows:


   
   
   ---------------------------------------------
                                            2010
   ---------------------------------------------
                                
   Distributions paid from:
   Ordinary income                   $20,089,651
   Long-term capital gain                     --
   ---------------------------------------------
     Total                           $20,089,651
   =============================================
   


                          Pioneer Value Fund | Semiannual Report | 3/31/11    33


   The following shows the components of distributable earnings on a federal
   income tax basis at September 30, 2010:


   
   
   ---------------------------------------------------
                                                  2010
   ---------------------------------------------------
                                     
   Distributable earnings:
   Undistributed ordinary income        $   12,417,938
   Capital loss carryforward              (722,904,359)
   Post-October loss deferred                 (119,558)
   Unrealized appreciation                  22,481,932
   ---------------------------------------------------
     Total                              $ (688,124,047)
   ===================================================
   


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


D. Forward Foreign Currency Contracts

   The Fund may enter into forward foreign currency contracts (contracts) for
   the purchase or sale of a specific foreign currency at a fixed price on a
   future date. 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 March 31, 2011, the
   Fund had no outstanding portfolio or settlement 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 $32,665 in underwriting commissions on the sale of Class A shares
   during the six months ended March 31, 2011.


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 its 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 do not pay distribution fees. All
   expenses and


34    Pioneer Value Fund | Semiannual Report | 3/31/11


   fees paid to the transfer agent, Pioneer Investment Management Shareholder
   Services, Inc. (PIMSS), for its services are allocated among the classes of
   shares 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 and at the same time, except that net
   investment income dividends to Class A, Class B, Class C and Class Y shares
   can reflect different transfer agent and distribution expense rates.


G. Class Actions

   During the period, the Fund recognized gains of $2,673,252 in settlement of
   class action lawsuits from several different companies, as reflected on the
   Statement of Operations.


H. Repurchase Agreements

   With respect to repurchase agreements entered into by the Fund, the value of
   the underlying securities (collateral), including accrued interest, is
   required to be equal to or in excess of the repurchase price. The collateral
   for all repurchase agreements is held in safekeeping in the customer-only
   account of the Fund's custodian or a subcustodian of the Fund. 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.


I. Securities Lending

   The Fund lends securities in its portfolio to certain broker-dealers or other
   institutional investors. When entering into a securities loan transaction,
   the Fund typically receives cash collateral from the borrower equal to at
   least the value of the securities loaned, which is invested in temporary
   investments. Credit Suisse AG, New York Branch, as the Fund's securities
   lending agent, manages the Fund's securities lending collateral. The income
   earned on the investment of collateral is shared with the borrower and the
   lending agent in payment of any rebate due to the borrower with respect to
   the securities loan, and in compensation for the lending agent's services to
   the Fund. The Fund also continues to receive payments in lieu of dividends or
   interest on the securities loaned. Gain or loss on the value of the loaned
   securities that may occur during the term of the loan will be for the account
   of the Fund. The amount of the collateral is required to be adjusted daily to
   reflect any price fluctuation in the value of the loaned securities. If the
   required market value of the collateral is less than the value of the loaned
   securities, the borrower is required to deliver additional collateral for the
   account of the Fund prior to the close of business on that day. The Fund has
   the right,


                          Pioneer Value Fund | Semiannual Report | 3/31/11    35


   under the lending agreement, to terminate the loan and recover the securities
   from the borrower with prior notice. The Fund is required to return the cash
   collateral to the borrower and could suffer a loss if the value of the
   collateral, as invested, has declined.


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 can
increase or decrease by a maximum of 0.10% based on the investment performance
of the Fund's Class A shares as compared to the Russell 1000 Value Index. The
performance comparison is made for a rolling 36-month period. In addition,
Pioneer contractually limits any positive adjustment of the Fund's management
fee to 0.10% of the Fund's average daily net assets on an annual basis (i.e.,
to a maximum of 0.70% after the performance adjustment). For the six months
ended March 31, 2011, the aggregate performance adjustment resulted in a
decrease to the basic fee of $222,578. For the six months ended March 31, 2011,
the effective management fee (excluding waivers and/or assumption of expenses)
was equivalent to 0.49% 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 as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$67,412 in management fees, administrative costs and certain other
reimbursements payable to PIM at March 31, 2011.


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.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.
For the six months ended March 31, 2011, such out-of-pocket expenses by class
of shares were as follows:




----------------------------------------
Shareholder Communications:
----------------------------------------
                              
Class A                         $638,953
Class B                            3,512
Class C                            2,565
Class Y                            1,895
----------------------------------------
  Total                         $646,925
========================================


36    Pioneer Value Fund | Semiannual Report | 3/31/11


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $230,418, in transfer agent fees and out-of-pocket
reimbursements payable to PIMSS at March 31, 2011.


4. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B and Class C
shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net
assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the
average daily net assets attributable to Class B and Class C shares. The fee
for Class B and Class C shares 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 $11,255 in distribution fees payable to PFD at March 31,
2011.

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 (within 12 months for purchases made on or after
April 1, 2009). 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%, based on the lower
of cost or market value of shares being redeemed. Shares purchased as part of
an exchange remain subject to any CDSC that applied to the original purchase of
those shares. There is no CDSC for Class Y shares. Proceeds from the CDSCs are
paid to PFD. For the six months ended March 31, 2011, CDSCs in the amount of
$3,753 were paid to PFD.


5. Expense Offset Arrangements

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 six months ended March 31, 2011, the Fund's
expenses were not reduced under such arrangements.


6. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a $165 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 the amount available


                          Pioneer Value Fund | Semiannual Report | 3/31/11    37


under the facility or the limits set for borrowing by the Fund's prospectus and
the 1940 Act. Interest on borrowings is payable at the higher of the London
Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an
annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on
an annualized basis. The Funds pay an annual commitment fee for this facility.
The commitment fee is allocated among participating Funds based on an
allocation schedule set forth in the credit agreement. For the six months ended
March 31, 2011, the Fund had no borrowings under this agreement.


7. Pending Litigation

The Fund is currently involved in a litigation matter in Germany. A German
financial intermediary, now deceased, apparently opened an account in the name
of the plaintiffs, a married couple, and later misappropriated the assets. The
plaintiffs filed a lawsuit against the Fund and an affiliate seeking recovery
for the misappropriated assets, alleging negligence and breach of contract. The
Fund believes that these claims are without merit and is defending the matter
vigorously. As of March 31, 2011, it is reasonably possible that an adverse
outcome may result. Currently, the amount of any judgment cannot reasonably be
estimated. Under the terms of an indemnification agreement, PIM and certain
affiliates have agreed to indemnify the Fund for its losses and costs related
to this litigation should there be an adverse outcome.


8. Subsequent Events

In preparing these financial statements, PIM has evaluated the impact of all
events and transactions for potential recognition or disclosure and has
determined that there were no subsequent events requiring recognition or
disclosure in the financial statements.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Value Fund (the Fund) pursuant to an investment advisory agreement
between PIM and the Fund. In order for PIM to remain the investment adviser of
the Fund, the Trustees of the Fund must determine annually whether to renew the
investment advisory agreement for the Fund.

The contract review process began in March 2010 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the
process. In July 2010, the Trustees approved the format of the contract review
materials and submitted their formal request to PIM to furnish information
necessary to evaluate the terms of the investment advisory agreement. The
contract review materials were provided to the Trustees in July 2010 and
September 2010. After reviewing and discussing the materials, the Trustees
submitted a request for additional information to PIM, and materials were
provided in response to this request. Meetings of the Independent Trustees of
the Fund were held in July, September, October, and November, 2010 to review
and discuss the contract review materials. In addition, the Trustees took into
account the information related to the Fund provided to the Trustees at each
regularly scheduled meeting.

At a meeting held on November 16, 2010, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the 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 renewal of the agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for
the Fund, its research process and its process for trade execution. The
Trustees considered the resources of PIM and the personnel of PIM who provide
investment management services to the Fund. The Trustees considered the
non-investment resources and personnel of PIM involved in PIM's services to the
Fund, including PIM's compliance and legal resources and personnel. In
addition, the Trustees considered the arrangements put in place to retain key
investment and other personnel. The Trustees also considered the substantial


                          Pioneer Value Fund | Semiannual Report | 3/31/11    39


attention and high priority given by PIM's senior management to the Pioneer
fund complex.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by PIM to the Fund were
satisfactory and consistent with the terms of the 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
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 fifth quintile of its Morningstar
category for the one, three, five and ten year periods ended June 30, 2010. (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 discussed the reasons for the Fund's underperformance
with PIM in view of the Fund's investment approach and the market conditions
present during the relevant periods. The Trustees agreed that they would
continue to monitor the performance of the Fund closely.

Management Fee and Expenses
The Trustees considered information showing 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 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 Trust 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, 2010 was in the second quintile relative to the management fees
paid by other funds in its Morningstar peer group for the comparable period.
The Trustees also considered that the Fund's management fee is adjusted upward
or downward based on the Fund's performance and considered the breakpoints in
the management fee schedule and the reduced fee rates above certain asset
levels. The Trustees considered that the Fund's expense ratio for


40    Pioneer Value Fund | Semiannual Report | 3/31/11


the twelve months ended June 30, 2010 was in the first quintile relative to its
Strategic Insight peer group for the comparable period.

The Trustees also reviewed management fees charged by PIM to its institutional
and other clients. In evaluating the fees associated with PIM's client
accounts, the Trustees took into account the respective demands, resources and
complexity associated with the Fund and client accounts. The Trustees noted
that in some instances the fee rates for those clients were lower than the
management fee for the Fund and considered that, under the investment advisory
agreement with the Fund, PIM performs additional services for the Fund that it
does not provide to those other clients or services that are broader in scope,
including oversight of the Fund's other service providers and activities
related to compliance and the extensive regulatory and tax regimes to which the
Fund is subject.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of the services provided by
PIM. The Trustees also concluded that the Fund's expense ratio was reasonable
taking into account the nature and quality of services provided by PIM.

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
concluded that PIM's profitability with respect to the management of the Fund
was not unreasonable.

Economies of Scale
The Trustees considered PIM's views relating to economies of scale in
connection with the Pioneer Funds as fund assets grow and the extent to which
any such economies of scale are shared with funds and fund shareholders. The
Trustees recognize that economies of scale are difficult to identify and
quantify and that, among other factors that may be relevant, are the following:
fee levels, expense subsidization, investment by PIM in research and analytical
capabilities and PIM's commitment and resource allocation to the Funds. The
Trustees noted that profitability also may be an indicator of the availability
of any economies of scale, although profitability may vary for other reasons
particularly, for example during the recent difficult periods for financial
markets, as the level of services was maintained notwithstanding a significant
decline in


                          Pioneer Value Fund | Semiannual Report | 3/31/11    41


PIM's fee revenues from the Funds. Accordingly, the Trustees concluded that
economies of scale, if any, were being appropriately shared with the Fund.

Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered the character and amount of fees paid by the
Fund, other than under the investment advisory agreement, for services provided
by PIM and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. The Trustees
also considered the benefits to the Fund and 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 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
investment advisory agreement between PIM and the Fund, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the 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.

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
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

N/A

(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
