President's Letter

Dear Shareowner,

Stock and bond markets around the globe have begun to recover over the past
year from one of their most tumultuous periods in history. This is a welcome
relief, and we are generally optimistic about the prospects for the economy
going forward. Still, challenges remain. Unemployment is high; consumer demand
and loan growth are weak; and housing has not returned to normal.

At Pioneer, we have long advocated the benefits of investing for the long term.
This strategy has generally performed well for many investors. Those who
remained invested in the market during the downturn have most likely seen their
portfolios start to recover over the past year, as the Dow Jones Industrial
Average climbed back from the depressed levels we saw in early 2009. Many bond
investors have similarly seen a strong rebound, with a broad-based recovery
occurring across many different fixed-income asset classes. The riskiest asset
classes, such as high-yield bonds, outperformed other fixed-income asset
classes during most of 2009.

At Pioneer, we are not changing the 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. While we see potential opportunities for making money in many corners
of the markets around the globe, it takes research and experience to separate
solid investment opportunities from speculation.

Following this difficult period, many investors are rethinking their approach
to investing and risk management. Some are questioning whether the basic
investment principles they were taught in the past are still useful in today's
markets. Complicating matters is that financial markets remain unpredictable.
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.

investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Portfolio Management Discussion | 12/31/09

After a gloomy start to 2009, real estate investments recovered nicely
throughout the balance of the year. The sector's rebound was catalyzed by
several factors suggesting that it had successfully weathered the worst of the
recession. In the following interview, Matthew Troxell of AEW Capital
Management, L.P., Pioneer Real Estate Shares' subadviser, discusses the
environment for real estate investing and for the Fund over the 12 months ended
December 31, 2009.

Q  What contributed to the turnaround in the real estate market over the 12
   months ended December 31, 2009?

A  Early in the Fund's fiscal year, a global recession, frozen credit markets,
   rising unemployment, and waning investor sentiment contributed to difficult
   conditions. The credit markets were especially challenging for real estate
   investment trusts (REITs), as the dearth of third-party commercial mortgage
   capital available, the higher cost of available debt, and tightened lending
   standards curtailed commercial real estate transactions, which, in turn,
   depressed property valuations.

   Sentiment began to improve in March 2009, when indicators suggested that
   the U.S. economy was beginning to stabilize. As the 12-month reporting
   period progressed, REITs benefited from the positive influence of new
   equity issuance activity, improving capital market conditions, a
   strengthening of the financial sector, and a general perception that most
   REITs had survived the worst of the recession.

Q  How did the Fund perform over the 12 months ended December 31, 2009?

A  Pioneer Real Estate Shares Class A shares returned 30.15% at net asset value
   over the 12 months ended December 31, 2009, while the Fund's benchmark, the
   Morgan Stanley Capital International (MSCI) U.S. REIT Index, returned 28.61%.
   Over the same period, the average return of the 229 real estate funds tracked
   by Lipper, Inc., returned 30.34%.

   On the heels of its worst-ever annual performance in 2008, the U.S. REIT
   market started 2009 in dismal fashion, losing approximately 40% from
   January 1 through early March. However, the sector's rally that began in
   March 2009 continued largely unabated through the final three quarters of
   the year. The Fund's solid returns and outperformance of its benchmark for
   the fiscal year were the result of effective stock selection, particularly
   in the regional mall, office and diversified sectors.

Q  Which holdings or weightings contributed to the Fund's strong results during
   the 12-month period ended December 31, 2009?

A  Top contributors to the Fund's performance included overweight positions in
   Macerich, a regional mall REIT, and HRPT Properties, an office REIT. Macerich
   benefited from the firm's efforts to deleverage and eliminate much of its
   near-term balance sheet risks. HRPT Properties rallied on the strength of the
   company's stable balance sheet and a lack of exposure to development
   property. From a sector allocation perspective, the Fund's underweight to
   health care, which underperformed on a relative basis, and overweight
   positioning in regional malls, which outperformed on a relative basis,
   contributed positively to benchmark-relative performance over the 12-month
   period.

Q  Which holdings or weightings proved most disappointing for the Fund over the
   12 months ended December 31, 2009?

A  Shopping center company Regency Centers suffered significant erosion in its
   share price early in 2009, which was the result of the weakened retail
   environment and concerns over the company's exposure to development. However,
   the company's stock price has since recovered somewhat, as the thawing in the
   credit markets has allowed it to reduce its debt and eliminate most of its
   near-term liquidity concerns. Kilroy Realty, an office REIT, struggled in the
   first quarter of 2009 because of market concerns over the company's exposure
   to Southern California -- which remains economically depressed -- as well as
   some scheduled lease expirations. Kilroy's shares subsequently recovered,
   considerably, on the merits of its relatively strong balance sheet and
   positive investor sentiment towards the company's limited exposure to new
   development.

   On a sector basis, the Fund's overweighting to the storage sector, which
   underperformed on a relative basis, and an underweight to the hotel sector,
   which outperformed on a relative basis, were detractors from performance
   over the 12-month period. The Fund's modest cash balance also detracted
   from performance relative to the MSCI REIT Index, in light of the REIT
   sector's positive absolute returns for the year.

Q  Given the market's recovery, are the fundamentals in the various property
   sectors showing improvement?

A  While an economic recovery is under way, market fundamentals in all property
   types continue to deteriorate, and we believe they likely will continue to do
   so well into 2010. The lack of job growth is translating into weak leasing
   demand in every sector. Not surprisingly, vacancy rates are at record levels
   in retail, apartment and industrial markets. Some office market rents are
   down by more than 20% from peak levels, and if leasing incentives and tenant
   improvements are factored in, that number rises even more.


                     Pioneer Real Estate Shares | Annual Report | 12/31/09     5


   Conditions in the apartment sector have been impacted both negatively and
   positively by troubles in the single-family housing sector. Rising
   foreclosures and stricter mortgage underwriting standards are forcing some
   home buyers and would-be buyers to become renters, but rentals of
   investor-owned homes and condominiums are providing housing alternatives to
   apartments. The conditions are likely to persist until a clear bottom is
   reached in single-family fundamentals. With home prices nearing a bottom,
   pent-up sales are likely to limit any strong rebound in prices, as sellers
   who have been trapped in their homes over the past several years will be
   putting houses on the market at the first sign of increased sales velocity.

   In the hotel sector, occupancies have declined recently compared with
   levels from a year ago, and room rates are down by 5 to 10 percent. Luxury
   hotels have been especially hard hit. Hotel fundamentals should show rapid
   improvement as confidence improves, given the night-to-night nature of
   their leases. However, revenue per available room will continue to be under
   pressure as long as both leisure and business travelers remain cautious
   about spending.

   On a positive note, there already has been some slowing in the rate of
   decline in all of the major real estate sectors. Vacancy rates have been
   climbing at a much slower rate in recent quarters, and we expect that such
   measures will begin to top out during 2010. Even rent declines began to
   flatten in late 2009.

Q  What is your outlook for the real estate market and the Fund in 2010?

A  We believe real estate market conditions will remain difficult in 2010, but
   will show improvement compared with the very challenging environment of the
   past two years. While it appears that the worst of the downturn is behind us,
   we believe a lack of job growth will translate into weak leasing demand
   fundamentals in every sector for the foreseeable future.

   Against that backdrop, our investment process for the Fund will continue to
   focus on securities selection within each property sector, with the goal of
   identifying those companies that we believe are mispriced relative to their
   peers and, thus, represent the greatest relative value and strongest price
   appreciation potential, as well as lower downside risk.

property management, environmental liabilities, uninsured damage, increased
competition, or changes in real estate tax laws. 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 or sectors.

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 1.85%, 3.25%,
  2.89% and 1.06% for Class A, Class B, Class C and Class Y shares,
  respectively, multiplied by the average account value over the period,
  multiplied by 184/365 (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.

28    Pioneer Real Estate Shares | Annual Report | 12/31/09


Notes to Financial Statements | 12/31/09

1. Organization and Significant Accounting Policies

Pioneer Real Estate Shares (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 to seek long-term
growth of capital. Current income is a secondary objective.

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
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.

Because the Fund may invest a substantial portion of its assets in Real Estate
Investment Trusts (REITs), the Fund may be subject to certain risks associated
with direct investments in REITs. REITs may be affected by changes in the value
of their underlying properties and by defaults of their borrowers or tenants.
REITs depend generally on their ability to generate cash flow to make
distributions to shareowners, and certain REITs have self-liquidation
provisions by which mortgages held may be paid in full and distributions of
capital returns may be made at any time. In addition, the performance of a REIT
may be affected by its failure to qualify for tax-free pass through of income
under the Internal Revenue Code or its failure to maintain exemption from
registration under the Investment Company Act of 1940. The Fund's prospectuses


                    Pioneer Real Estate Shares | Annual Report | 12/31/09     29


contain unaudited information regarding the Fund's principal risks. Please
refer to those documents when considering the Fund's 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
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 fair
   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 fair 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 December 31, 2009, there were no securities that were valued using fair
   value methods. Inputs used in the valuation of a security using fair value
   methods 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


30     Pioneer Real Estate Shares | Annual Report | 12/31/09


   data in the exercise of reasonable diligence. Interest income, including
   interest on income bearing cash accounts, 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. 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 remain 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 net realized gain on investment transactions, or as from paid-in
   capital, depending on the type of book/tax differences that may exist.

   A portion of the dividend income recorded by the Fund is from distributions
   by publicly traded REITs, and such distributions for tax purposes may also
   consist of capital gains and return of capital. The actual return of capital
   and capital gains portions of such distributions will be determined by formal
   notifications from the REITs subsequent to the calendar year-end.
   Distributions received from the REITs that are determined to be a return of
   capital are recorded by the Fund as a reduction of the cost basis of the
   securities held and those determined to be capital gain are reflected as such
   on the Statement of Operations.

   The Fund has elected to defer $1,435,822 of capital losses recognized between
   November 1, 2009 and December 31, 2009 to its fiscal year ending December 31,
   2010.

   At December 31, 2009, the Fund had a net capital loss carryforward of
   $27,375,691 of which $7,060,199 will expire in 2016 and $20,315,492 will
   expire in 2017 if not utilized.


                    Pioneer Real Estate Shares | Annual Report | 12/31/09     31


   The tax character of distributions paid during the years ended December 31,
   2009 and December 31, 2008 was as follows:




- ------------------------------------------------------------
                                      2009             2008
- ------------------------------------------------------------
                                           
   Distributions paid from:
   Ordinary income              $2,739,314       $3,426,917
   Return of capital             1,105,994        2,170,453
- ------------------------------------------------------------
     Total                      $3,845,308       $5,597,370
============================================================


  The following shows the components of distributable earnings on a federal
  income tax basis at December 31, 2009:





- ------------------------------------------------------------
                                                       2009
- ------------------------------------------------------------
                                            
   Distributable earnings:
   Capital loss carryforward                   $(27,375,691)
   Post-October loss deferred                    (1,435,822)
   Unrealized appreciation                       25,014,734
- ------------------------------------------------------------
     Total                                     $ (3,796,779)
============================================================


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


C. 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 approximately $8,848 in underwriting commissions on the sale of Class
   A shares during the year ended December 31, 2009.


D. 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 their 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. 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 and at the same time, except that net
   investment


32     Pioneer Real Estate Shares | Annual Report | 12/31/09


   income dividends to Class A, Class B, Class C and Class Y shares can reflect
   different transfer agent and distribution expense rates.


E. 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 fair 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 fair 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 fair value of the loaned
   securities. If the required market value of the collateral is less than the
   fair value of the loaned securities, the borrower is required to deliver
   additional collateral for the account of the Fund prior to the close of the
   next business day. The Fund has the right, 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.


F. 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.


2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.80% of
the Fund's average daily net assets up to $1 billion; and 0.75% of the Fund's
average daily net assets over $1 billion. Prior to January 1, 2010, management
fees were calculated daily at the annual rate of 0.80% of the Fund's average
daily net assets. PIM pays a portion of the fee it receives from the Fund to
AEW Capital Management, L.P. as compensation for sub-advisory services to the
Fund.


                    Pioneer Real Estate Shares | Annual Report | 12/31/09     33


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
$4,013 in management fees, administrative costs and certain other
reimbursements payable to PIM at December 31, 2009.


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 year ended December 31, 2009, such out-of-pocket expenses by class of
shares were as follows:




- --------------------------------------------
 Shareholder Communications:
- --------------------------------------------
                                
 Class A                           $ 70,287
 Class B                             18,005
 Class C                             14,267
 Class Y                              2,945
- --------------------------------------------
   Total                           $105,504
============================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $32,323 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at December 31, 2009.


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 $974 in distribution fees payable to PFD at December 31,
2009.

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


34     Pioneer Real Estate Shares | Annual Report | 12/31/09


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 year ended December 31, 2009,
CDSCs in the amount of $11,512 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 year ended December 31, 2009, the Fund's expenses
were reduced by $23 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 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 year ended
December 31, 2009, the Fund had no borrowings under this agreement.


7. Subsequent Events

In preparing these financial statements, PIM has evaluated the impact of all
events and transactions for potential recognition or disclosure through
February 22, 2010 and has determined that there were no subsequent events
requiring recognition or disclosure in the financial statements.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareowners of
Pioneer Real Estate Shares:
- --------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Real Estate Shares (the "Fund"), including the schedule of investments, as of
December 31, 2009, 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 five years in
the period then ended. 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 December 31, 2009, by correspondence
with the custodian and broker 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 Real Estate Shares at December 31, 2009, 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 financial highlights for each of the five
years in the period then ended, in conformity with U.S. generally accepted
accounting principles.

Approval of Investment Advisory and Sub-Advisory Agreements
(unaudited)


Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Real Estate Shares (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. PIM has retained AEW Capital Management,
L.P. (AEW) to serve as the sub-adviser to the Fund pursuant to a sub-advisory
agreement between PIM and the sub-adviser. In order for PIM and AEW to remain
the investment adviser and sub-adviser of the Fund, respectively, the Trustees
of the Fund must determine annually whether to renew the investment advisory
agreement and the sub-advisory agreement for the Fund.

The contract review process began in March 2009 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the
process. In July 2009, 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 and the
sub-advisory agreement. The contract review materials were provided to the
Trustees in August 2009. After reviewing and discussing the materials, the
Trustees submitted a request for additional information to PIM in September
2009, 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, 2009 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 10, 2009, based on their evaluation of the
information provided by PIM, the sub-adviser and third parties, the Trustees of
the Fund, including the independent Trustees voting separately, unanimously
approved the renewal of the investment advisory agreement and the sub-advisory
agreement for another year. In considering the renewal of the investment
advisory agreement and the sub-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 agreements.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services that had
been provided by PIM and the sub-adviser to the Fund, taking into account the
investment objective and strategy of the Fund. The Trustees reviewed the terms
of the investment advisory agreement and the sub-advisory agreement. The
Trustees also reviewed the sub-adviser's investment approach for the Fund, its
research process and its process for trade execution. The Trustees considered
the resources of PIM and the sub-adviser and the personnel of PIM and the


                    Pioneer Real Estate Shares | Annual Report | 12/31/09     37


sub-adviser 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. The Trustees also considered the substantial 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 (including the sub-adviser) 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 and the sub-adviser to
the Fund were satisfactory and consistent with the terms of the investment
advisory agreement and the sub-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 third quintile of its Morningstar
category for the one, three and ten year periods ended June 30, 2009 and in the
second quintile of its Morningstar category for the five year period ended June
30, 2009. (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 concluded that the investment performance
of the Fund was satisfactory.

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 also considered
that PIM, not the Fund, paid the sub-adviser pursuant to the sub-advisory
agreement. The Trustees evaluated both the fee under the sub-advisory agreement
and the portion of the fee under the investment advisory agreement retained by
PIM.


38     Pioneer Real Estate Shares | Annual Report | 12/31/09


The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2009 was in the third 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 expense ratio for the twelve
months ended June 30, 2009 was in the fifth quintile relative to its Strategic
Insight peer group for the comparable period. The Trustees considered that,
effective January 1, 2010, a breakpoint would be added to the Fund's management
fee schedule on assets over $1 billion.

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 also reviewed management fees charged by the sub-
adviser to its other clients. The Trustees noted that in most instances the fee
rates for those clients were higher than the sub-advisory fees paid to the sub-
adviser with respect to the Fund.

The Trustees concluded that the management fee payable by the Fund to PIM, as
well as the fees payable by PIM to the sub-adviser of the Fund, were reasonable
in relation to the nature and quality of the services provided by PIM and the
sub-adviser. The Trustees also concluded that the Fund's expense ratio was
reasonable taking into account the nature and quality of services provided by
PIM and the sub-adviser.

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. The Trustees further
considered the sub-advisory fees received by the sub-adviser with respect to
the Fund and the percentage that such fees represented of the sub-adviser's
overall revenues (for the 12-month period ended December 31, 2008). 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


                    Pioneer Real Estate Shares | Annual Report | 12/31/09     39


expenses. The Trustees concluded that the profit margins with respect to the
management of the Fund were 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 difficult year in 2008 for financial
markets, as the level of services was maintained notwithstanding a significant
decline in 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 each of PIM and the sub-adviser
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 the sub-adviser 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 each of PIM and the sub-adviser
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 each of PIM and the sub-adviser 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 each of
the investment advisory agreement between PIM and the Fund and the sub-advisory
agreement between PIM and the sub-adviser, including the fees payable
thereunder, was fair and reasonable and voted to approve the proposed renewal
of each of the investment advisory agreement and the sub-advisory agreement for

 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.

                 from the audit procedures as a
                 foundation to complete the
                 project.  In most cases, if

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
                 typically well-defined and
                 governed by accounting
                 professional standards (AICPA,

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.

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 December 31, 2009 and 2008, 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.

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
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 $8,290 in 2009 and $8,290 in
2008.

(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.

paragraph (b) of this Item with respect to any purchase made by or on
behalf of the registrant or any affiliated purchaser, as defined in

similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
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
