LETTER FROM THE PRESIDENT 6/30/03
- --------------------------------------------------------------------------------

Dear Shareowners,
- --------------------------------------------------------------------------------

With the fading of concerns over the Iraq        -------------------------------
war, investors whose attention had been
focused overseas were buoyed by hints of         Pioneer's new
increased economic activity at home. The         president

multinational companies operating in
countries with stronger currencies. One
possible lesson to be learned from the
market's decline and recovery is the
importance of staying invested. Those who
stayed with their commitments participated in
the recent rally, while those who remained on
the sidelines had to play catch-up. If the
protracted slump caused your investment
discipline to slip, this may be an ideal time
to contact your financial advisor for guid
ance on resuming your investment program.

Our style focuses on companies, not on forecasts

There are always risks, of course, and the direction of the economy is something
of a puzzle at the moment. If it continues to struggle for very long, investors
may once again seek shelter in short-term commitments. However, Pioneer's
portfolio managers and analysts do not base investment decisions on economic
assumptions. Instead, as it has since our founding in 1928, our value-focused
investment style requires complete understanding of a company and its potential.
That means intensive analysis of financial reports, visits to companies and
detailed discussions with corporate managers. When we discover potential that
appears to exceed the market's valuation, that company becomes a candidate for
investment. Our research efforts are aided in no small measure by the global
resources of our parent organization, UniCredito Italiano S.p.A.

Like everyone at Pioneer, I appreciate your continued confidence in our products
and services.

Respectfully,

/s/ Osbert M. Hood

PORTFOLIO MANAGEMENT DISCUSSION 6/30/03
- --------------------------------------------------------------------------------

Following the swift conclusion of the war in Iraq in early April, equity
markets staged an impressive rebound, contributing to strong gains for the six
months ended June 30, 2003 - the first half of your Fund's fiscal year. It
appears that the relatively short duration of the war in Iraq helped to temper
investors' anxiety and ease the uncertainty overshadowing stock markets
worldwide. In the following interview, portfolio manager Jeff Caira suggests
that while volatility and slow economic growth are complicating a recovery, the
outlook is improving.

Q:  The Fund had positive returns going into the April rally. How did it perform
    for the six months ended June 30, 2003?

A:  The Fund achieved favorable gains for the first half of its fiscal year,
    which is rewarding given the fact that many sectors of the real estate
    market were showing increasing vulnerability to the weaker U.S. economy. In
    April, investors returned to the market with enthusiasm, buoyed by interest
    rate cuts in both Europe and the United States and a modestly improving U.S.
    macroeconomic outlook.

    For the six months ended June 30, 2003, the Fund's Class A, B and C shares
    increased 11.46%, 11.06% and 11.11%, respectively, at net asset value. The
    Fund underperformed its benchmark, the Wilshire Real Estate Securities
    Index, which rose 13.47% for the same period. Poor stock selection in the
    hotel sector and our decision to limit the Fund's exposure to strip malls
    during a period of strong performance accounts for the disparity.

Q:  Why did the Fund's hotel stocks prove to be so disappointing?

A:  In addition to choosing stocks that lagged the hotel sector's spring rally,
    our decision to underweight (relative to the benchmark) the Fund's exposure
    to this sector had the added misfortune of limiting the Fund's participation
    in the rebound. One holding, MeriStar Hospitality, which owns over 100
    hotels around the United States, was very volatile. It was down 66% from
    December 31, 2002 to March 11, 2003, then turned around and rose 130% from
    March 11, 2003 to June 30, 2003. For the entire six months under review,
    however, the holding was down 22%. Furthermore, Starwood Hotels & Resorts,
    which we'd chosen to slightly underweight, outperformed the benchmark for
    the six-month period.


                                                                               7

    Our preference for larger, high-quality real-estate companies also proved to
    be a drawback during the rally. It appears that some of the rally's strength
    was driven by income-oriented investors who, confronted with the prospects
    of falling interest rates, bought high-yielding real-estate investments -
    regardless of the company's asset quality, property type or long-term
    prospects. The heightened demand drove prices higher, contributing to their
    outperformance.

Q:  Given investors' penchant for higher-yielding real-estate stocks, could you
    provide an example of a holding that pays above-average income while meeting
    your criteria for quality and sustainable growth potential?

A:  Certainly. Prentiss Properties, which offered a dividend yield of 7.3% on
    June 30, 2003 manages office properties in a variety of markets - both
    high-growth, low-barriers-to-entry markets and higher-barriers-to-entry
    markets. Their properties are primarily located in Washington, D.C.,
    Chicago, Dallas, Austin and Northern California. With its strong management
    team, this real estate investment trust strives for an attractive return on
    capital, which is backed by solid financials, and has a history of market
    leadership that has helped it consistently to outperform many of its peers.

Q:  Despite sluggish economic growth, retail stocks turned in strong
    performance. Why was that?

A:  Retail stocks benefited from continued improvement in fundamentals, as
    landlords were generally able to increase occupancy levels in retail centers
    and generate strong rent increases on expiring and new leases. Additionally,
    there were fewer tenant bankruptcies than there were for the same period
    last year, keeping cash flows strong. Investors continued to bid the stocks
    up despite valuation levels at the high end of the historical range.
    Investors appeared to be downplaying valuation levels in favor of the strong
    absolute and even stronger relative fundamentals of that property type.

    Although we increased investments in retail stocks during the reporting
    period, which has been very beneficial for the Fund, the portfolio did hold
    a slight underweight position (relative to the Fund's benchmark) in the
    community-center sector, which rallied strongly. We did not believe that the
    underlying fundamentals supporting community centers justified the continued
    share price appreciation and kept the Fund's weighting below that of the
    benchmark. As it turned out, prices of community-center property companies
    appreciated more strongly than most other property types. Two of the Fund's
    largest investments in the retail sector, Pan Pacific Retail Properties and
    Weingarten Realty Investors, were significant contributors to performance
    for the six months under review.

Q:  Has the outlook for the office sector improved?

A:  Office real estate investment trusts are still experiencing weak
    fundamentals, since the sector is so highly correlated to the direction of
    economic growth, albeit with a lag. Vacancy rates have risen, and expiring
    contractual rent agreements, which experienced dramatic increases in recent
    years, are, in many cases, in jeopardy of being renewed at today's lower
    rent levels. We're watching the group closely to look for signs of job
    growth in the economy, which could signal a subsequent turnaround in office
    property fundamentals. We are pleased to see that the supply of new office
    buildings has moderated, which bodes well for the sector once job growth
    improves and demand increases.

Q:  Are you optimistic about prospects for the real estate sector longer term?

A:  Yes. We continue to believe that the longer-term benefits of real-estate
    investments remain intact - namely above-average dividend yields, relatively
    stable cash flows and modest growth. The industry's current fundamentals are
    weak, however, and we don't foresee substantial improvement, with the
    exception of hotel REITs, until economic growth resumes. We believe job
    growth will be critical to such a recovery.


                                                                               9

    The Fund's sector diversification is less defensive than it was six months
    ago - underscoring our improving but still cautious outlook. During the
    reporting period, we reduced heavy positions in industrial, manufactured
    housing and office REITs and slightly increased the portfolio's exposure to
    retail by adding to community-center property companies. Since real estate
    is a lagging indicator of the economy's strength by about six months, we
    want to be sure the portfolio is well positioned for an eventual recovery
    before it becomes widely apparent. Thus, we'll continue to focus on
    attractively priced companies that we feel have the best total-return
    potential, solid cash flow, and the best prospects for profitability in a
    recovering economy.

    The preceding information is the opinion of Fund management. Past
    performance is no guarantee of future results, and there is no guarantee
    that market forecasts discussed will be realized.

NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Real Estate Shares (the Fund) is a Delaware business 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 - Class A, Class B, Class C and Class Y
shares. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has equal rights to voting, redemptions, dividends
and liquidation, except that the level of transfer agent and distribution fees
may differ among classes. Class A, Class B and Class C shareowners have
exclusive voting rights with respect to the distribution plan for each class.
There is no distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with
accounting principles generally accepted in the United States of America 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 revenues and expenses during the
reporting periods. Actual results could differ from those estimates. The
following is a summary of significant accounting policies consistently followed
by the Fund, which are in conformity with those generally accepted in the
investment company industry.

A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value is
    computed once daily, on each day the New York Stock Exchange is open, as of
    the close of regular trading on the Exchange. In computing the net asset
    value, securities are valued at the last sale price on the principal
    exchange where they are traded. Securities that have not traded on the date
    of valuation, or securities for which sale prices are not generally
    reported, are valued at the mean between the last bid and asked prices.
    Securities for which market quotations are not readily available are valued
    at their fair values as determined by, or under the direction of, the Board
    of Trustees. Dividend income is recorded on the ex-dividend


                                                                              21


Pioneer Real Estate Shares

NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

    date, except that certain dividends from foreign securities where the
    ex-dividend date may have passed are recorded as soon as the Fund is
    informed of the ex-dividend data in exercise of reasonable diligence.
    Interest income, including interest on income bearing cash accounts, is
    recorded on the accrual basis. Temporary cash investments are valued at
    amortized cost.

    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 by
    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.

    Gains and losses on sales of investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes. It
    is the Fund's practice to first select for sale those securities that have
    the highest cost and also qualify for long-term capital gain or loss
    treatment for 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.

    The characterization of distributions to shareowners for financial reporting
    purposes is determined in accordance with federal income tax rules.
    Therefore, the source of the Fund's distributions may be shown in the
    accompanying financial statements as either from or in excess of net
    investment income or net realized gain on investment transactions, or 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.

    The tax character of current year distributions paid will be determined at
    the end of the current fiscal year. The tax character of distributions paid
    during the year ended December 31, 2002 were as follows:

   *Included in the Fund's distributions from ordinary income for the year ended

    shareowners as ordinary income distributions.

NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

    The difference between book-basis and tax-basis unrealized appreciation is
    primarily 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 UniCredito Italiano S.p.A.
    (UniCredito Italiano), earned $9,797 in underwriting commissions on the sale
    of Fund shares during the six months ended June 30, 2003.

D. Class Allocations

    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. Class Y shares are not subject to a distribution plan.
    Shareowners of each class share 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). Income, common expenses and realized and unrealized gains and losses are
    calculated at the Fund level and allocated daily to all classes of shares
    based on their respective percentage of adjusted net assets at the beginning
    of the day.

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

F. Security Lending

    The Fund lends securities in its portfolio to certain broker-dealers or
    other institutional investors, with the Fund's custodian acting as the
    lending agent. When entering into a loan, the Fund receives collateral,
    which is maintained by the custodian and earns income in the form of
    negotiated lenders' fees. The Fund also continues to receive interest or
    dividends on the securities loaned, and gain or loss in the fair value of
    the securities loaned that may occur during


24


Pioneer Real Estate Shares
- --------------------------------------------------------------------------------

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

    the term of the loan will be for the account of the Fund. The loans are
    secured by collateral of at least 102%, at all times, of the fair value of
    the securities loaned. The fair value of the collateral is adjusted daily to
    reflect any price fluctuation in the value of the loaned securities. The
    value of loaned securities and cash collateral at period end are disclosed
    on the balance sheet. The Fund invests cash collateral in the Securities
    Lending Investment Fund, which is managed by Brown Brothers Harriman & Co.,
    the Fund's custodian.

2. Management Agreement

Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser,
manages the Fund's portfolio and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the annual rate of
0.80% of the Fund's average daily net assets.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At June 30, 2003, $66,465 was payable to PIM
related to management fees, administrative fees and certain other services.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Fund at
negotiated rates. Included in due to affiliates is $16,597 in transfer agent
fees payable to PIMSS at June 30, 2003.

4. Distribution Plans

The Fund adopted Plans of Distribution with respect to Class A, Class B and
Class C shares (Class A Plan, Class B Plan and Class C Plan) in accordance with
Rule 12b-1 under the Investment Company Act of 1940. Pursuant to the Class A
Plan, the Fund pays PFD a service fee of up to 0.25% of the Fund's average
daily net assets attributable to Class A shares in reimbursement of its actual
expenditures to finance activities primarily intended to result in the sale of
Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Fund
pays PFD 1.00% of the average daily net assets attributable to each class of
shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee
paid as compensation for personal services and/or


                                                                              25

account maintenance services or distribution services with regard to Class B
and Class C shares. Included in due to affiliates is $44,138 in distribution
fees payable to PFD at June 30, 2003.

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 one year of purchase. Class B shares that are redeemed within six years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Proceeds from the CDSCs are paid to PFD. For the six months ended June 30,
2003, CDSCs in the amount of $23,269 were paid to PFD.

5. Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended June 30, 2003,
the Fund's expenses were reduced by $1,482 under such arrangements.

6. Line of Credit Facility

The Fund along with certain other funds in the Pioneer Family of Funds (the
Funds) collectively participate in a $50 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 $50 million or the limits set
by its prospectus for borrowings. Interest on collective borrowings is payable
at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an

    (i)  Has at least one audit committee financial expert serving on its audit
         committee; or

    (ii) Does not have an audit committee financial expert serving on its audit
         committee.

    (2) If the registrant provides the disclosure required by paragraph
(a)(1)(i) of this Item, it must disclose the name of the audit committee
financial expert and whether that person is "independent." In order to be
considered "independent" for purposes of this Item, a member of an audit
committee may not, other than in his or her capacity as a member of the audit

    (i)  Accept directly or indirectly any consulting, advisory, or other
         compensatory fee from the issuer; or

    (ii) Be an "interested person" of the investment company as defined in
         Section 2(a)(19) of the Act (15 U.S.C. 80a-2(a)(19)).

    (3) If the registrant provides the disclosure required by paragraph (a)(1)
(ii) of this Item, it must explain why it does not have an audit committee

of the last two fiscal years for professional services rendered by the principal
accountant for the audit of the registrant's annual financial statements or
services that are normally provided by the accountant in connection with
statutory and regulatory filings or engagements for those fiscal years.

(b) Disclose, under the caption AUDIT-RELATED FEES, the aggregate fees billed in
each of the last two fiscal years for assurance and related services by the
principal accountant that are reasonably related to the performance of the audit
of the registrant's financial statements and are not reported under
paragraph (a) of this Item. Registrants shall describe the nature of the
services comprising the fees disclosed under this category.

(c) Disclose, under the caption TAX FEES, the aggregate fees billed in each of
the last two fiscal years for professional services rendered by the principal
accountant for tax compliance, tax advice, and tax planning. Registrants shall
describe the nature of the services comprising the fees disclosed under this
category.



(d) Disclose, under the caption ALL OTHER FEES, the aggregate fees billed in
each of the last two fiscal years for products and services provided by the
principal accountant, other than the services reported in paragraphs (a) through
(c) of this Item. Registrants shall describe the nature of the services
comprising the fees disclosed under this category.

(e) (1) Disclose the audit committee's pre-approval policies and procedures
described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.

    (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.

(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.

(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.

Not applicable for semiannual reports; to be answered on annual submissions
after December 15, 2003.
