This is a welcome relief, and we are generally optimistic about the prospects for the economy going forward. Still, challenges remain. Unemployment is high; consumer demand and loan growth are weak; and housing has not returned to normal. At Pioneer, we have long advocated the benefits of investing for the long term. This strategy has generally performed well for many investors. Those who remained invested in the market during the downturn have most likely seen their portfolios start to recover over the past year, as the Dow Jones Industrial Average climbed back from the depressed levels we saw in early 2009. Many bond investors have similarly seen a strong rebound, with a broad-based recovery occurring across many different fixed-income asset classes. The riskiest asset classes, such as high-yield bonds, outperformed other fixed-income asset classes during most of 2009. At Pioneer, we are not changing the approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential opportunities for making money in many corners of the markets around the globe, it takes research and experience to separate solid investment opportunities from speculation. Following this difficult period, many investors are rethinking their approach to investing and risk management. Some are questioning whether the basic investment principles they were taught in the past are still useful in today's markets. Complicating matters is that financial markets remain unpredictable. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 2 Pioneer Real Estate Shares | Semiannual Report | 6/30/10 We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. We greatly appreciate your trust in us and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Real Estate Shares | Semiannual Report | 6/30/10 3 Portfolio Management Discussion | 6/30/10 Investor concerns about the viability of the economic recovery, sputtering employment growth, Europe's sovereign debt crisis, and the oil spill in the Gulf of Mexico weighed heavily on stocks during the first half of 2010. However, real estate investments held up much better than the broader equity markets, which generally posted negative returns for the six months ended June 30, 2010. In the following interview, Matthew Troxell of AEW Capital Management, L.P., the Fund's sub-adviser, discusses his strategies for managing Pioneer Real Estate Shares amidst the increased volatility over the six months ended June 30, 2010. Q How did the real estate market fare over the six months ended June 30, 2010? A While the real estate sector was not necessarily immune to the broader market woes, it outperformed the major U.S. stock markets considerably over the six-month period, due in large part to positive year-to-date fund flows into the sector, a stabilization of real estate market fundamentals, low interest rates, and increased demand for higher-yielding securities. Real estate investment trusts (REITs) also were aided early in the period by news that Simon Property Group, along with other REITs, expressed an interest in buying all or most of General Growth Properties. Q How did the Fund perform in that environment over the six months ended June 30, 2010? A For the six months ended June 30, 2010, Pioneer Real Estate Shares' Class A shares returned 7.11% at net asset value, while the Fund's benchmark, the Morgan Stanley Capital International (MSCI) U.S. REIT Index1, returned 5.70%. Over the same period, the average return of the 235 funds in Lipper's Real Estate Funds category was 5.21%. The Fund's solid outperformance relative to the benchmark was attributable to strong stock selection in the office, industrial and storage sectors. From a sector-allocation perspective, the Fund's overweights in the outperforming apartment and storage sectors also contributed positively to relative performance. However, the Fund's underweight in the hotel sector, which outperformed, was a detractor. Also, a modest cash balance detracted from performance relative to the benchmark in light of the REIT sector's positive absolute returns for the six-month period. Q Did the Fund's investment strategy change during the six-month period ended June 30, 2010? A Our investment strategy did not change materially during the period, nor did we make any significant changes to the Fund's portfolio. We continue to 4 Pioneer Real Estate Shares | Semiannual Report | 6/30/10 maintain a portfolio that is well diversified by property type and geography, making changes continually at the margin to overweight or underweight sectors and individual stocks depending upon our view of market conditions and company-specific variables, respectively. Q What holdings contributed positively to the Fund's performance over the six months ended June 30, 2010? A The Fund's overweight positions in top-performing DuPont Fabros Technology, which owns and operates wholesale data centers, the apartment REIT Equity Residential, and storage REIT Extra Space Storage were particularly rewarding to performance over the six-month period. DuPont Fabros Technology's performance was due in large part to the stabilized condition of the company's existing property portfolio and continued steady demand for wholesale data center space. The company's stock also enjoyed a favorable reception by investors to its equity offering in May 2010. The performance of Equity Residential reflected the defensive characteristics of the company's solid balance sheet, its high-quality portfolio, and the belief that the company is well positioned to benefit from rising rents in many of its core markets. Extra Space Storage's outperformance also was driven largely by the company's stable balance sheet and high-quality asset portfolio as well as its continued solid operating results and manageable development pipeline. Q What holdings proved most disappointing for the Fund during the six months ended June 30, 2010? A While the reporting period was very rewarding on an absolute and relative basis, there were some disappointments, including an overweight exposure to apartment REIT Camden Property Trust and hotel REIT PebbleBrook Hotel Trust. Camden was one of the strongest-performing multifamily companies in 2009, and so some retrenchment in its stock price during the first half of this year was not surprising and may have been attributable to profit-taking. The company's first quarter announcement of a reduction in its development and predevelopment activity, which resulted in a one-time impairment charge, also contributed to its underperformance. We continue to maintain a Fund overweight in Camden, as we believe it represents a solid relative value in the apartment sector and, given its strong balance sheet and solid management team, is well positioned to benefit from an eventual improvement in the apartment market's fundamentals. PebbleBrook Hotel Trust lagged its hotel peers during the six-month period due to management's decision not to deploy the majority of cash raised from its December 2009 initial public offering until late in the reporting period, when the company announced several acquisitions. We believe the company represents an attractive relative value in the hotel sector due to its unburdened balance sheet and enviable positioning, given its ability to continue acquiring high-quality assets. Pioneer Real Estate Shares | Semiannual Report | 6/30/10 5 Q Given the U.S. economy's uneven recovery, how have the various property types in which the Fund's assets are invested been faring? A Leasing demand fundamentals remain weak in most sectors and vacancy rates are at record levels in retail and industrial markets, and still deteriorating in most office markets. Some office market rents are down by more than 20% from their peak levels of a few years ago, and are down by even more if leasing incentives and tenant improvements are factored in. The apartment sector improved in the first half of 2010 and, by some measures, has seen occupancies improve substantially. That sector benefits from shorter leases in an economic recovery and, true to form, has been the earliest of the four major sectors to turn the corner, though the gains thus far have been modest. Outside of the apartment sector, there has been some improvement in the rate of decline in the rest of the major real estate sectors. Vacancy rates have been climbing at a much slower rate in recent quarters, and we still expect that such measures will begin to top out during 2010, though the recent weakness in labor markets could push that into 2011. Even rent declines have been flattening recently, and the NCREIF (National Council of Real Estate Investment Fiduciaries) Index of private real estate returns was modestly positive in the first quarter of 2010. That said, we feel it will take some time for markets to bottom out. Demand has been the primary driver of leasing weakness, as supply pipelines were never overly large and the credit crisis put many new and even ongoing projects on the shelf. Going forward, we expect net operating income (NOI) in the office, retail and, to some extent, industrial sectors to be held back by the expiration of leases signed before the downturn, with the office sector's NOI being the last to recover given the longer-term nature of those leases. In the hotel sector, revenue per available room (REVPAR) growth has been positive for much of 2010, although that is largely a function of comparisons to the depressed markets from a year earlier. Occupancies are running several percentage points ahead of 2009, but rates are flat. We believe hotel fundamentals should continue to improve through 2011, though they could be particularly sensitive to any lack of confidence in the business sector. Q What is your outlook for the balance of 2010? A The U.S. REIT market has made solid gains since the sector's rally began in March 2009. Companies have benefited from their ability to focus on streamlining operations and improving balance sheets. While the recent pullback has brought valuations to more realistic -- but still above average -- levels, we believe performance expectations for the remainder of 2010 should be tempered. We think prices have limited room to move much higher in the near term considering the current backdrop of uncertainty in 6 Pioneer Real Estate Shares | Semiannual Report | 6/30/10 the broader stock market and the economy. Economic data in June has indicated that the economy could be slowing, which, in turn, could put some pressure on the future NOI growth of REITs, and on property values. We expect the REIT sector's direction over the near term will continue to be guided by macroeconomic developments, such as conditions in the credit and job markets. Our investment process for the Fund will continue to focus on security selection within each property sector, emphasizing those companies that we believe represent the greatest relative value, the strongest price appreciation potential, and the lowest downside risk. 1 The MSCI information may only be used for your internal use, may not be reproduced or redisseminated in any form and may not be used as a basis for or a component of any financial instruments or products or indices.

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, 2010 through June 30, 2010. - ----------------------------------------------------------------------------------- Share Class A B C Y - ----------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 1/1/10 - ----------------------------------------------------------------------------------- Ending Account $1,071.10 $1,064.10 $1,066.40 $1,074.10 Value on 6/30/10 - ----------------------------------------------------------------------------------- Expenses Paid $8.42 $15.05 $12.81 $5.14 During Period* - ----------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.64%, 2.94%, 2.50% and 1.00% 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 | Semiannual Report | 6/30/10 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.

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 three classes of shares designated as Class A, Class C and Class Y shares. Effective as of the close of business on December 31, 2009, Class B shares are no longer offered to new or existing shareholders, except that dividends and/or capital gain distributions may continue to be reinvested in Class B shares, and shareholders may exchange their Class B shares for Class B shares of other Pioneer funds, as permitted by existing exchange privileges. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. Because the Fund may invest a substantial portion of its assets in Real Estate Investment Trusts (REITs), the Fund may be subject to certain risks associated with direct investments in REITs. REITs may be affected by changes in the value of their underlying properties and by defaults of their borrowers or tenants. REITs depend generally on their ability to generate cash flow to make distributions to shareowners, and certain REITs have self-liquidation provisions by which mortgages held may be paid in full and distributions of capital returns may be made at any time. In addition, the performance of a REIT may be affected by its failure to qualify for tax-free pass through of income under the Internal Revenue Code or its failure to maintain exemption from registration under the Investment Company Act of 1940. The Fund's prospectus Pioneer Real Estate Shares | Semiannual Report | 6/30/10 29 contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry. A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange are fair valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are fair valued at the mean between the last bid and asked prices. Securities for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Thus, the valuation of the Fund's securities may differ from exchange prices. At June 30, 2010, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Inputs used in the valuation of a security using fair value methods include credit ratings, the financial condition of the company, current market conditions and comparable securities. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. 30 Pioneer Real Estate Shares | Semiannual Report | 6/30/10 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, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. A portion of the dividend income recorded by the Fund is from distributions by publicly traded REITs, and such distributions for tax purposes may also consist of capital gains and return of capital. The actual return of capital and capital gains portions of such distributions will be determined by formal notifications from the REITs subsequent to the calendar year-end. Distributions received from the REITs that are determined to be a return of capital are recorded by the Fund as a reduction of the cost basis of the securities held and those determined to be capital gain are reflected as such on the Statement of Operations. The tax character of current year distributions will be determined at the end of the Fund's taxable year. The tax character of distributions paid during the year ended December 31, 2009 was as follows: - -------------------------------------------------------------------------------- 2009 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $2,739,314 Return of capital 1,105,994 - -------------------------------------------------------------------------------- Total $3,845,308 ================================================================================ Pioneer Real Estate Shares | Semiannual Report | 6/30/10 31 The following shows the components of distributable earnings on a federal income tax basis at December 31, 2009: - -------------------------------------------------------------------------------- 2009 - -------------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $(27,375,691) Post-October loss deferred (1,435,822) Unrealized appreciation 25,014,734 - -------------------------------------------------------------------------------- Total $ (3,796,779) ================================================================================ The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned approximately $6,711 in underwriting commissions on the sale of Class A shares during the six months ended June 30, 2010. 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. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated 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. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the 32 Pioneer Real Estate Shares | Semiannual Report | 6/30/10 fair value of the securities loaned, which is invested in temporary investments. Credit Suisse AG, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive payments in lieu of dividends or interest on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the fair value of the loaned securities. If the required market value of the collateral is less than the fair value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of the next business day. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund is required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. F. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.80% of the Fund's average daily net assets up to $1 billion; and 0.75% of the Fund's average daily net assets over $1 billion. Prior to January 1, 2010, management fees were calculated daily at the annual rate of 0.80% of the Fund's average daily net assets. PIM pays a portion of the fee it receives from the Fund to AEW Capital Management, L.P. as compensation for sub-advisory services to the Fund. 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 $2,956 in management fees, administrative costs and certain other reimbursements payable to PIM at June 30, 2010. Pioneer Real Estate Shares | Semiannual Report | 6/30/10 33 3.

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.
