Those were particularly useful guides during the past year, as U.S. and global stock and bond markets grew strongly during the period. In the first half of 2007, U.S. equity markets proved resilient in the face of a slowing economy. The Standard & Poor's 500 Stock Index set a record high in late May and returned 7% in the first half of the year. The Dow Jones Industrial Average returned 9%, building on a five-year bull market. International developed and emerging markets equities performed even better than U.S. equities, with the MSCI EAFE (developed market) Index returning 11% and the MSCI Emerging Markets Index returning 18% in the first half of 2007. The general U.S. bond market, as measured by the Lehman Brothers Aggregate Bond Index, returned 1% in the first half, as rising bond yields produced price declines that partially offset income earned. The high yield market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 3%, reflecting its higher yields and continuing investor confidence in the strength of the U.S. economy. The United States has enjoyed a cyclical recovery with strong economic growth. While the growth has slowed recently, we believe that continuing growth at a moderate rate appears to be more likely than a recession. Slowing growth was due in large part to a decline in the rate of new home construction and in part to the lagging effects of rising energy and commodity prices as well as rising short-term interest rates. Slowing economic activity is also due in part to the natural maturation of the cyclical expansion as U.S. factories approach full utilization and the labor market approaches full employment. This slowdown is therefore not entirely unwelcome, as it reduces the threat of higher inflation. The Federal Reserve Board (the Fed) continues to highlight its commitment to keeping inflationary pressures contained. This is in keeping with "best practices" among the world's central banks: low and stable inflation is believed to be the best backdrop for stable economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so the Fed's policy is investor-friendly. 2 Letter In Europe, solid GDP growth driven by a positive operating environment for European companies, especially those that are benefiting from strong export markets for their goods and services, is driving unemployment lower and supporting growing consumption. European inflationary pressures appear to be largely under control, with the European Central bank remaining strongly vigilant. Japanese economic growth continues to make progress, and the country has become a more attractive market as deflationary problems recede. Economic growth in emerging market countries remains faster than in the developed world as they continue to "catch up." Leading the way is China, which continues its rise as a world economic power. Looking forward, we believe that the overall climate for equity investors generally will continue to be positive, although valuations are less attractive than they were a year ago, and a correction after a period of strong performance is possible. Rising yields have depressed year-to-date bond returns, but increased the attractiveness of bonds looking forward. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to their particular risk tolerance and investment objective.

While the correction and its inherent volatility warrants a more cautionary approach, the underlying fundamentals remain generally strong across each of the major property types, as Matthew Troxell of AEW Capital Management, L.P., the Fund's subadviser, explains in the following interview. Q: What triggered the decline in REIT prices? A: The sector's downturn, which commenced in early February, was caused by several factors, including the impact of the market's slightly diminished (albeit still positive) expectations for REIT earnings in 2007. Turbulence in the sector increased further in late February and early March due to problems in both the Chinese market and the U.S. sub-prime lending market, which impacted markets everywhere - including REITs. The sector's most precipitous drop occurred in June (REITs were down over 9% for the month), as rising long-term interest rates and widening credit spreads weighed heavily on the sector. We also believe that REIT share prices have recently fallen in some measure because of profit taking, as investors came to grips with the fact that the sector's spectacular seven-year rally may have run its course. Q: How did the Fund perform during the semiannual period? A: Reflecting the sector's weak performance, the Fund's Class A shares posted a total return of -7.66% at net asset value for the six months ended June 30, 2007. In comparison, the Fund's benchmark index, Dow Jones Wilshire Real Estate Securities Index returned, -6.19% and the average return of the 301 real estate funds tracked by Lipper, Inc. was -4.71% for the same period. The major driver of the Fund's underperformance relative to the benchmark index and its peer group was the disappointing returns of stocks in the shopping center, office and hotel sectors. The negative performance in these sectors was partially offset by the positive returns of holdings in the storage and triple net lease sectors. The Fund's exposure to the underperforming healthcare sector, which struggled in the final weeks of the semiannual period, impacted its performance relative to the benchmark, as the index does not have any exposure to this sector. 4 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What investments contributed to performance? A: Despite the sector's overall decline, several holdings turned in positive performance. Two of the top individual contributors to the Fund's performance during the first half of 2007 included Starwood Hotels & Resorts Worldwide and Archstone-Smith Trust (apartment). Starwood's strong performance for the period was largely attributable to speculation that the company might be bought, which began after the removal of the company's CEO in early April. Archstone-Smith Trust benefited significantly from its announcement that it was being acquired at a significant premium to its respective share price. Q: What investments detracted from performance? A: Since real estate stocks have been such strong performers in recent years, posting an annualized return of over 22% between January 2000 and December 2006, some moderation in performance during the first half of 2007 was not surprising. Two of the most disappointing stocks held by the Fund - Boston Properties (office) and Developers Diversified Realty (shopping centers) - declined even though we do not believe that there were any significant events that led to this weakness. We still currently believe both companies represent solid values relative to their peers and continued to maintain the Fund's overweight positions in both stocks as of the date of this shareholder report. Public Storage - the largest company in the storage sector - was negatively impacted by an overall slowdown in the industry and in same-store sales, which, in turn, was driven by lagging home sales. 5 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/07 (continued) - -------------------------------------------------------------------------------- Q: Despite the decline, are the underlying fundamentals of the various property types that the Fund is invested in still positive? A: Yes. While geographic regions continue to offer varying degrees of strength, we believe that the underlying fundamentals generally remain strong across each of the major property types. In the retail sector, property occupancies are still high, tenant interest for available space is still strong, and overall same store sales remain healthy. Office and industrial fundamentals also remain solid as evidenced by continued high occupancy levels and rising rents, with coastal locations doing exceptionally well. Supply is increasing, but not to a point that has warranted significant concerns. Conditions remain strong in the apartment sector relative to historical averages, although overall rental growth appears to be slowing somewhat. In the near term, we believe that the sector will continue to be supported by the softening housing market and lenders' tightening credit standards for home buyers. We believe that the fundamentals remain sound in the lodging sector as well, despite moderating revenue per available room growth year-over-year and increasing supply levels. Q: Did the Fund's sector distribution change noticeably during the six months? A: We didn't make any significant changes to the Fund's sector allocations versus the benchmark index during the period. The Fund's industry weightings are a function of our bottom-up investment process, which focuses on securities selection within each sector. Q: Have you become more cautious in your outlook? A: Yes, despite the solid fundamentals. We expect continued volatility in the REIT market during the remainder of the year, with several factors playing a role in the Fund's performance and the duration of the correction. The factors include higher interest rates, the health of the consumer and the overall economy, and potential increases in commercial real estate lending spreads, which could have a negative impact on asset prices and the privatization activity that has been so important to the sector's growth recently. 6 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- It appears that the public property markets have been more preoccupied with these issues than the private property markets, and their REIT share prices reflected many of these concerns by the end of the period. Although REITs on average were trading at over a 10% discount to underlying net asset values at the end of the period and we believe property fundamentals remain generally firm, there appears to be few positive catalysts in the current environment. As always, we'll continue to place great importance on the quality of a company's balance sheet and earnings stream as we navigate this more challenging environment. 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. 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.

This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: 1. Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 2. Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Real Estate Shares Based on actual returns from January 1, 2007 through June 30, 2007 Share Class A B C Y - -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 On 1/1/07 Ending Account Value $ 923.40 $ 919.60 $ 919.70 $ 925.60 On 6/30/07 Expenses Paid During Period* $ 6.25 $ 10.52 $ 10.14 $ 4.25 * Expenses are equal to the Fund's annualized expense ratio of 1.31%, 2.21%, 2.13% and 0.89% for Class A, Class B, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 14 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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.

Pioneer Real Estate Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (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 - 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 each class of shares can bear different transfer agent and distribution fees and have exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B and Class C shareowners, respectively. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting year. Actual results could differ from those estimates. Information regarding the Fund's principal risks is contained in the Fund's prospectus. Please refer to those documents when considering the Fund's 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 following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are 27 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (unaudited) (continued) - -------------------------------------------------------------------------------- consistent with those policies generally accepted in the investment company industry. A. Security Valuation Security transactions are recorded on trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund also may use the fair value of a security, including a non-U.S. security, when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. At June 30, 2007 there were no securities fair valued. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income is recorded on the accrual basis. Temporary cash investments are valued at cost which approximates market value. 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. 28 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 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, 2006 were as follows: - -------------------------------------------------------------------------------- 2006 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income* $ 1,791,295 Long-term capital gain 13,062,292 ----------- $14,853,587 Return of capital - ----------- Total $14,853,587 =========== - -------------------------------------------------------------------------------- * Included in the Fund's distributions from 2006 ordinary income is $340,994 in excess of investment company taxable income, which, in accordance with applicable U.S. tax law, is taxable to shareowners as ordinary income distributions. 29 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (unaudited) (continued) - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at December 31, 2006. - -------------------------------------------------------------------------------- 2006 - -------------------------------------------------------------------------------- Undistributed long-term gain $ 1,658,666 Undistributed Ordinary Income 662,296 Unrealized appreciation 113,384,930 ------------ Total $115,705,892 ============ - -------------------------------------------------------------------------------- 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 on 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). PFD earned $49,530 in underwriting commissions on the sale of Class A shares during the six months ended June 30, 2007. 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 (see Note 4). 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. 30 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- E. Securities 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 payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in the Securities Lending Investment Fund, which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian. F. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian, or subcustodians. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredito Italiano, 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. PIM pays a portion of the fee it receives from the Fund to AEW Management and Advisors LP 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. At June 30, 31 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (unaudited) (continued) - -------------------------------------------------------------------------------- 2007, $10,793 was payable to PIM related to management fees, administrative costs and certain other services and is included in due to affiliates. 3.

Included in due to affiliates is $71,335 in transfer agent fees payable to PIMSS at June 30, 2007. 4. Distribution Plans The Fund adopted a Plan 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 of 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 account maintenance services or distribution services with regard to Class B and Class C shares. Included in due to affiliates is $4,694 in distribution fees payable to PFD at June 30, 2007. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.0%, 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 CDSC are paid to PFD. For the six months ended June 30, 2007, CDSCs in the amount of $33,085 were paid to PFD. 32 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended June 30, 2007, the Fund's expenses were not reduced by $12,672 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 $200 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of $200 million or the limits 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 annual commitment fee for this facility. The commitment fee is allocated among such Funds based on their respective borrowing limits. For the six months ended June 30, 2007, the Fund had no borrowings under this agreement. 7. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. 33 Pioneer Real Estate Shares - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Trustees Officers John F.

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.
