President's Letter

Dear Shareowner,

As we move past the midway point of 2014, U.S. economic growth is still expected
to exceed 2% for the full calendar year, despite the fact that U.S. gross
domestic product (GDP) for the first quarter was revised down to - 2.9% in May.
The markets, in fact, almost completely ignored that bad news, as more timely
data -- especially labor market data -- pointed to continuing economic strength.
By mid-year, the number of people filing initial unemployment claims and the
number of job openings were at levels last seen during the boom years of 2005
through 2007, and unemployment was down to just over 6%. Barring an external
shock, we think it's likely that the domestic economic expansion will continue.
The Federal Reserve System (the Fed) is widely expected to end its stimulative
QE (quantitative easing) program by the end of this year and to begin raising
the Federal funds rate in 2015; two more signs that the U.S. economic recovery
is on increasingly solid footing. The timing and pace of Fed's actions remain
uncertain, however, as Fed Chair Janet Yellen has continually stressed that Fed
policy will be sensitive to incoming economic data, and any signs of
accelerating inflation could prompt an earlier increase in the Federal funds
rate.

A modestly improving European economy and continuing economic improvement in
Japan appear likely to result in improving global economic growth in the second
half of 2014, further supporting the U.S. economy. Some slack remains in the
labor markets and capacity utilization, which offers the potential for
continuing non-inflationary growth.

While the U.S. economy appears robust and the global economy seems to be
improving, there are still weaknesses and risks to the economic outlook. Risks
of an adverse shock also remain. Military conflicts and political tensions are
widespread, with particular concerns about recent developments in the Middle
East that could prove disruptive to the global oil supply. While most of the
widely recognized risks may already be "priced into" the market, we caution
against complacency and believe investors should continue to expect market
volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns. 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, keeping in mind that there is no single best strategy that
works for every investor.

Pioneer's investment teams have, since 1928, sought out attractive opportunities
in equity and bond markets, using in-depth research to identify undervalued
individual securities, and using thoughtful risk management to construct
portfolios which seek to balance potential risks and rewards in an ever-changing
world.

Portfolio Management Discussion | 6/30/14

In the following interview, Matthew Troxell of AEW Capital Management, L.P.,
sub-adviser for Pioneer Real Estate Shares, discusses the market environment for
real estate-related investments and the Fund's performance during the six-month
period ended June 30, 2014.

Q    How did the Fund perform during the six-months ended June 30, 2014?

A    The Fund's Class A shares returned 17.15% at net asset value during the
     six-month period ended June 30, 2014, while the Fund's benchmark, the
     Morgan Stanley Capital International (MSCI) U.S. REIT Index (the MSCI
     Index)(1), returned 17.68%. During the same period, the average return of
     the 258 mutual funds in Lipper's Real Estate Funds category was 16.44%, and
     the average return of the 279 mutual funds in Morningstar's Real Estate
     Funds category was 16.57%.

Q    What were the main reasons for the Fund's slight underperformance of the
     MSCI Index during the six-month period ended June 30, 2014? Specifically,
     which investment strategies or individual holdings had the biggest effects
     on the Fund's relative returns?

A    On a relative basis, the Fund underperformed the benchmark during the
     period, a result largely attributable to negative stock selection results
     in the diversified, industrial and hotel sectors as well as the portfolio's
     modest cash position, which was a detractor in light of the real estate
     investment trust (REIT) sector's strong absolute performance.

     The individual positions that detracted the most from the Fund's
     benchmark-relative performance during the six-month period included
     overweights in the underperforming REITs Forest City Enterprises and Hilton
     Worldwide, and an underweight to the outperforming apartment REIT Essex
     Property Trust. Shares of Forest City came under selling pressure during
     the period when investors had a negative reaction to

     management's development and capital expenditure plans. Hilton has strong
     fundamentals in our view, but lagged many of its peers in the lodging
     sector during the first half of 2014 in anticipation of a private equity
     group's trimming its stake in the hotelier. The Fund's underweight exposure
     in Essex Property Trust hurt relative performance as the REIT rallied in
     response to strong market conditions on the west coast.

Q    Which of your investment strategies augmented the Fund's performance during
     the six-month period ended June 30, 2014, and which strategies detracted
     from performance?

A    The Fund's strong absolute performance during the period was driven by both
     stock selection results and sector allocation strategies. With regard to
     stock selection, the portfolio's holdings in the triple-net-lease, regional
     mall, and office sectors made the largest contributions to returns. (A
     triple-net-lease is a lease agreement that designates the lessee, or
     tenant, as being solely responsible for all of the costs relating to the
     asset being leased, in addition to the rental fee applied under the lease.
     Under a triple-net-lease, the tenant typically pays the net real estate
     taxes owed on the leased asset as well as the net building insurance
     premiums and net common area maintenance costs. Because the tenant is
     covering these "triple" costs - which would otherwise be the responsibility
     of the property owner - the rent charged under a triple-net-lease agreement
     is generally lower than the rent charged in a standard lease agreement.)

     The holdings that contributed the most to the Fund's performance during the
     six-month period included a significant underweight position in the
     underperforming triple-net-lease REIT American Realty Capital Properties,
     which posted a negative return for the first half of 2014. Overweight
     Portfolio positions in the outperforming office REIT Kilroy Realty and the
     apartment REIT Equity Residential also contributed to returns. Kilroy
     Realty's portfolio of assets - like those of Essex Property Trust
     (mentioned previously) - continued to benefit during the period from
     strength in the west coast markets, particularly in San Francisco and
     Seattle. Equity Residential reported solid quarterly earnings results
     during the period, which were driven by strong apartment demand.

     In addition, despite strong performance from the Portfolio's individual
     holdings in the triple-net-lease sector, the sector as a whole
     underperformed during the period, and so being underweight there
     contributed to the Portfolio's returns. An overweight position in the
     outperforming diversified sector also benefited the Fund's returns during
     the period.

                      Pioneer Real Estate Shares | Semiannual Report | 6/30/14 5


Q    Did you implement any major changes to the Fund's strategy during the
     six-month period ended June 30, 2014?

A    We didn't make any significant changes to the Fund's portfolio during the
     period. The portfolio continues to be well diversified* by property type
     and geographic region, and our investment process remains focused on
     security selection within each property sector. Throughout the period, the
     portfolio had a bias toward companies with stronger balance sheets and
     higher-quality assets as well as toward companies with development
     pipelines that we believe are undervalued by the market. Based on improving
     property market fundamentals and relative valuations within the REIT
     sector, however, our preference for attractive value led us to increase the
     portfolio's overweight in the office sector and move to a bigger
     underweight in the triple-net-lease sector.

     From a sector standpoint, we continue to underweight the Fund in sectors
     that are very yield-driven and have, in our view, less operating upside.
     Those sectors include health care and triple net lease. With regard to
     triple-net-lease REITs, we believe the long-term nature of the income
     streams in the sector provides limited ability to offset rising interest
     rates, especially when compared with REITs in other sectors that may be
     able to capitalize on rising rents in a strong economy. The Fund also is
     underweight in the lodging sector, as we believe the undeniably strong
     fundamentals of the sector are largely reflected in current prices (the
     lodging group has returned nearly 35% over the past year).

     We have overweighted the portfolio in the diversified sector, which
     represents a group of companies, in our view, that trade at a discount both
     to the assets that they own and to their pure-play REIT counterparts.
     Within the diversified sector, the Fund holds a larger-than-benchmark
     weighting in biotech lab-space REITs. Elsewhere, we remain positive on the
     storage sector, even though it has already enjoyed a decade of very strong
     growth. The REITs in the storage sector continue to demonstrate the ability
     to accretively add private portfolios to their platform. Finally, we see
     value in higher-quality mall and apartment REITs as well as select office
     and shopping center companies.

*    Diversification does not assure a profit nor protect against loss in a
     declining market.

Q    How would you characterize the health of the underlying subsectors of the
     REIT market as of June 30, 2014?

A    We saw general improvement in all subsectors of the REIT market during the
     six-month period, particularly during the second quarter. We expect 2014 to
     be the first year of the economic recovery where all of the major REIT
     subsectors see positive growth in net operating income (NOI). The
     shorter-lease sectors, such as apartments and self-storage, are seeing
     slowing, but still solid growth as occupancies stabilize at high levels,
     while the longer-lease sectors, such as office and retail, are still a few
     years away from peak NOI growth, in our opinion.

     Rents are moving up in all property types, and some longer-lease property
     types should soon transition into an environment where leases will be
     signed at higher rents than those currently in place, thus providing a
     boost to NOI. Supply risk remains minimal on a national level, with only
     the apartment sector now back to long-term construction averages. We are
     seeing some supply growth in a few select office and industrial markets,
     but the growth is generally targeted at locations with strong demand.

Q    How would you rate the attractiveness of REIT valuations at this point in
     the economic recovery?

A    REITs certainly benefited from the surprising drop in market interest rates
     during the first half of 2014. By period end, REIT valuations were at near
     long-term historical averages, making them appear relatively expensive
     compared with other equities, but attractive relative to bonds.

     The Federal Reserve (the Fed) is on pace to end its stimulative bond-buying
     program later this year. If U.S. economic data continues to improve,
     investors will eventually begin to focus on the timing of the Fed's first
     increase in the benchmark Federal funds rate. When interest rates
     eventually do rise over the next several years, we expect REIT performance
     gains to be driven more by earnings growth than by additional expansion of
     the multiples investors are willing to pay for cash flows.

Please refer to the Schedule of Investments on pages 17-19 for a full listing of
Fund securities.

The Fund invests in REIT securities, the value of which can fall for a variety
of reasons, such as declines in rental income, fluctuating interest rates, poor
property management, environmental liabilities, uninsured damage, increased
competition, or changes in real estate tax laws.

The Fund invests in a limited number of securities and, as a result, the Fund's
performance may be more volatile than the performance of other funds holding
more securities.

When interest rates rise, the prices of fixed-income securities in the Fund will
generally fall. Conversely, when interest rates fall, the prices of fixed-income
securities in the Fund will generally rise.

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.

These risks may increase share price volatility.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are

Index Definition
--------------------------------------------------------------------------------
The MSCI U.S. REIT Index is an unmanaged, widely used index comprising a broad
representation of the most actively traded real estate trusts, and is designed
to be a measure of real estate equity performance. Index returns are calculated
monthly, assume reinvestment of dividends and, unlike Fund returns, do not
reflect any fees, expenses or sales charges. It is not possible to invest
directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 11-14.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

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

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.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not reflect
the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a
1% sales charge, your returns would be lower than those shown above. "If Held"
results represent the percent change in net asset value per share. Returns would
have been lower had sales charges been reflected. 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

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Class Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results are
historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

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

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.

     respectively, multiplied by the average account value over the period,
     multiplied by 181/365 (to reflect the one-half year period).

Comparing Ongoing Fund Expenses (continued)

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.

Purchases and sales of securities (excluding temporary cash investments) for the
six months ended June 30, 2014 aggregated $13,570,074 and $4,996,188,
respectively.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below.

  Level 1 -- quoted prices in active markets for identical securities.

  Level 2 -- other significant observable inputs (including quoted prices for
             similar securities, interest rates, prepayment speeds, credit risk,
             etc.) See Notes to Financial Statements -- Note 1A.

  Level 3 -- significant unobservable inputs (including the Fund's own
             assumptions in determining fair value of investments) See Notes
             to Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods
(other than prices supplied by independent pricing services or broker-dealers)
as Level 3. See Notes to Financial Statements -- Note 1A.

Notes to Financial Statements | 6/30/14 (unaudited)

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 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.

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:

28 Pioneer Real Estate Shares | Semiannual Report | 6/30/14


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. Short-term fixed income
     securities with remaining maturities of sixty days or less generally are
     valued at amortized cost. Shares of money market mutual funds are valued at
     such funds' net asset value.

     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.

     Securities for which independent pricing services are unable to supply
     prices or for which market prices and/or quotations are not readily
     available or are considered to be unreliable are valued by a fair valuation
     team comprised of certain personnel of Pioneer Investment Management, Inc.
     (PIM), the Fund's investment adviser, pursuant to procedures adopted by the
     Fund's Board of Trustees. PIM's fair valuation team uses fair value methods
     approved by the Valuation Committee of the Board of Trustees. PIM's fair
     valuation team is responsible for monitoring developments that may impact
     fair valued securities and for discussing and assessing fair values on an
     ongoing basis, and at least quarterly, with the Valuation Committee of the
     Board of Trustees.

     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. 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. Examples of a significant
     event might include political or economic news, corporate restructurings,
     natural disasters, terrorist activity or trading halts. Thus, the valuation
     of the Fund's securities may differ significantly from exchange prices and
     such differences could be material.

     At June 30, 2014, there were no securities that were valued using fair
     value methods (other than securities that were valued using prices supplied
     by independent pricing services or broker-dealers).

     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

                     Pioneer Real Estate Shares | Semiannual Report | 6/30/14 29


     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 provision for federal income taxes is required.
     As of December 31, 2013, the Fund did not accrue any interest or penalties
     related to uncertain tax positions, which, if applicable, would be recorded
     as an income tax expense in the Statement of Operations. Tax returns filed
     within the prior three years remain subject to examination by Federal and
     State tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement purposes resulting from
     differences in the recognition or classification of income or distributions
     for financial statement and tax purposes. Capital accounts within the
     financial statements are adjusted for permanent book/tax differences to
     reflect tax character, but are not adjusted for temporary differences.

     The tax character of current year distributions payable will be determined
     at the end of the Fund's taxable year. The tax character of distributions
     paid during the years ended December 31, 2013 was as follows:

     
     
     ---------------------------------------------------------------------------
                                                                            2013
     ---------------------------------------------------------------------------
                                                                   
     Distributions paid from:
     Ordinary income                                                  $1,286,381
     Long-term capital gain                                            1,449,677
     ---------------------------------------------------------------------------
          Total                                                       $2,736,058
     ===========================================================================
     

     The following shows the components of distributable earnings on a federal
     income tax basis at December 31, 2013:

                                                                            2013
     ---------------------------------------------------------------------------
                                                                  
     Distributable Earnings:
     Undistributed long-term capital gain                            $ 1,239,344
     Net unrealized appreciation                                      53,485,771
     ---------------------------------------------------------------------------
          Total                                                      $54,725,115
     ===========================================================================
     

30 Pioneer Real Estate Shares | Semiannual Report | 6/30/14


     The difference between book-basis and tax-basis net 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 $5,991 in underwriting commissions on the sale of Class
     A shares during the six months ended June 30, 2014.

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 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 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.

E.   Risks

     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 prospectus contains unaudited information
     regarding the Fund's principal risks. Please refer to that document when
     considering the Fund's principal risks.

                     Pioneer Real Estate Shares | Semiannual Report | 6/30/14 31


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. 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% on assets over $1
billion. For the six months ended June 30, 2014, the effective management fee
(excluding waivers and/or assumption of expenses) was equal to 0.80% of the
Fund's 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.

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
$16,008 in management fees, administrative costs and certain other
reimbursements payable to PIM at June 30, 2014.

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 June 30, 2014, such out-of-pocket expenses by class of
shares were as follows:

================================================================================


32 Pioneer Real Estate Shares | Semiannual Report | 6/30/14


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $26,379 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at June 30, 2014.

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 $4,429 in distribution fees payable to PFD at June 30, 2014.

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 12 months of purchase. Class B shares that are redeemed within five years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within 12 months 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 June 30, 2014, CDSCs in
the amount of $858 were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended June 30, 2014, 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 committed, unsecured revolving line of credit
facility. Borrowings are used solely for temporary or emergency purposes. The
Fund

                     Pioneer Real Estate Shares | Semiannual Report | 6/30/14 33


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. The credit
facility in effect until February 12, 2014 was in the amount of $215 million. As
of February 12, 2014, the facility is in the amount of $240 million. Under such
facility, depending on the type of loan, interest on borrowings is payable at
the London Interbank Offered Rate (LIBOR) plus 0.90% (0.85% as of February 12,
2014) on an annualized basis, or the Alternate Base Rate, which is the greater
of (a) the facility's administrative agent's daily announced prime rate on the
borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c)
2% plus the overnight Euro dollar rate on the borrowing date. The Funds pay an
annual commitment fee to participate in a credit 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 June 30, 2014, the Fund had no
outstanding borrowings.

7. Change in Independent Registered Public Accounting Firm

The Board of Trustees of the Fund, with the approval and recommendation of the
Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's
independent registered public accounting firm for the fiscal year ending
December 31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which
resigned as the Fund's independent registered public accounting firm, effective
upon completion of the audit of the Fund's financial statements for the fiscal
year ended December 31, 2013.

During the periods that Ernst & Young LLP served as the Fund's independent
registered public accounting firm, including the Fund's two most recent fiscal
years, Ernst & Young LLP's reports on the financial statements of the Fund have
not contained an adverse opinion or disclaimer of opinion and have not been
qualified or modified as to uncertainty, audit scope or accounting principles.
Further, there have been no disagreements with Ernst & Young LLP on any matter
of accounting principles or practices, financial statement disclosure, or
auditing scope or procedure, which, if not resolved to the satisfaction of Ernst
& Young LLP would have caused Ernst & Young LLP to make reference to the subject
matter of the disagreement in connection with its report on the financial
statements. In addition, there have been no reportable events of the kind
described in Item 304 (a)(1)(v) of Regulation S-K under the Securities Exchange
Act of 1934.

8. Subsequent Event

Upcoming Conversion of Class B Shares

As of the close of business on November 10, 2014 (the "Conversion Date"), all
outstanding Class B shares of the Pioneer funds will be converted to Class A
shares. Shareholders may continue to hold their Class B shares until the
Conversion Date. Prior to the Conversion Date, redemptions of Class B shares are
subject to any applicable contingent deferred sales charges (CDSCs). Class A
shares acquired through the conversion will not be subject to CDSCs, nor will
any sales charges be assessed in connection with the conversion. After the
Conversion Date, subsequent purchases of Class A shares will be subject to sales
charges as described in the Fund's prospectus.

 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.

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are

                 professional standards (AICPA,
