Dear Shareowner,
- --------------------------------------------------------------------------------
As the global economy reacted to good and bad news of 2006, overall it managed
to keep chugging along with fairly stable growth. Looking back, the economic
stories included slowing economic growth bringing monetary tightening to an end
in the United States, price action in oil and other commodity markets
threatening to unsettle global growth and inflation, geopolitical uncertainties
and corporate earnings growth surpassing market expectations.

Global growth surpassed most analyst expectations in 2006. The International
Monetary Fund estimates world output increased by 5.1% in 2006, up from 4.9% in
2005 and above the 3.7% average annual pace of growth of the previous 20 years.
Growth is estimated to slow modestly in 2007 but to remain well above the
long-term average.

U.S. economic growth slowed gradually over 2006, with full-year growth of GDP
of 3.1%, modestly below 2005 growth but still strong enough to lower the
unemployment rate to 4.5%. While many observers were concerned that a weakening
housing sector could be a drag on consumer spending, the consumer has shown
resilience supported by a strong labor market and associated income growth and
by oil and gasoline prices falling from record highs in the second half of
2006. Corporate America has also proved resilient in the face of the slowing
housing sector, with business investment growing at its fastest rate since
2000.

The Federal Reserve stopped increasing interest rates in mid-2006, but has
retained its bias to tighten rates, reflecting upside risks to inflation,
particularly from the tight labor market, and confidence that the economy
remained on solid ground. Consumers welcomed the relief from oil prices that
peaked at mid-year and fell sharply towards year-end. Likewise, in the second
half of 2006, they benefited from the modest easing of core inflation (which
excludes energy and food items), though such core inflation remains above what
is generally considered the central bank's "comfort zone."

The European economy surpassed many economists' expectations in 2006. Eurozone
GDP grew at a 3% pace, much stronger than its 1.8% average annual growth pace
since 2000. Underlying this strength has been buoyant and broad-based strength
in business sentiment and investment and in exports. While household
consumption showed mixed results, the unemployment rate fell to 7.7% by the end
of 2006. The European Central Bank raised interest rates gradually to 3.5% over
the course of 2006, reflecting firm economic growth, steadily tightening labor
market conditions, and fast growing money supply. Core inflation in the
Eurozone remains reasonably benign, at roughly 1.5% per annum. European stock
markets posted strong returns; appreciation of the Euro relative to both the
dollar and Yen made the Eurozone stock market the top performer of 2006.

The Japanese economy continued to grow firmly in 2006. Business investment was
the major driver of expansion as increasing capacity utilization and better
sentiment encouraged a new wave of investment. As deflation ended, the Bank of
Japan ended its zero interest rate policy, although it has raised rates to only
0.25% in 2006. After a strong showing in 2005, the Japanese stock market posted
only muted gains in 2006.

Emerging economies enjoyed strong, relatively uninterrupted economic growth in
2006. Good financing conditions, buoyant commodity prices, which boosted income
and investment in commodity exporting countries, and strong export demand from
developed economies drove this growth. The emerging market stock

index was very strong in early 2006, sold off to near start-of-year levels,
then rallied to finish the year only marginally behind the Eurozone. We believe
similar growth can be expected in the emerging markets if current domestic
economic and political conditions prevail.

While global economic momentum has started to slow, we expect the global
economy to continue growing firmly in 2007, supported by business investment,
rising employment, and lower energy prices. A slowdown in the U.S. growth rate
would be welcome, since rapid growth could increase the risk of inflationary
pressures, which would force the Federal Reserve to raise interest rates. We
expect Europe and Japan to grow similarly, while emerging market economies are
expected to continue their strong growth. In this scenario, fixed-income assets
are expected to produce total returns generally in line with their current
yields, while equities are expected to produce returns generally in line with
earnings growth, which we forecast to be moderately above bond yields.

Our cautiously optimistic outlook on most regions of the world and asset
classes reinforces the importance of Pioneer Investments' message that
investors should remain diversified, take a long-term view rather than
over-reacting to breaking news, and base investment decisions on economic and
market fundamentals rather than on emotion. Our investment philosophy and
approach continue to be based on the use of fundamental research to identify a
range of opportunities that offer an attractive balance of risk and reward to
help Fund shareowners work toward achieving their long-term goals.

Respectfully,

PORTFOLIO MANAGEMENT DISCUSSION 2/28/07
- --------------------------------------------------------------------------------

In the following interview, portfolio manager Piergaetano Iaccarino discusses
the factors that influenced performance for the semiannual period ended
February 28, 2007.


Q:  How did the Fund perform over the six-month period ended February 28, 2007?



A:  The Fund's Class A shares had a total return of 9.19% (of net asset value,
    for the six months) as compared to 10.58% for the MSCI World Index. The
    global environment for equities was generally positive for the six-month
    period, and that was reflected in the Fund's performance.


    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:  Can you review the Fund's overall investment approach?


A:  We look at mid- and large-capitalization stocks in more than 30 countries
    and from that universe build a somewhat focused portfolio of less than 50
    stocks. Each stock that we hold will generally be overweighted by at
    least one percent versus the MSCI World Index. In selecting securities
    for the portfolio, we look for "growth at a reasonable price," and so
    there is a strong value component to our analysis. We try to find
    companies that not only are benefiting from operating efficiencies, as
    reflected in things like increased market share and revenues, but that
    also use their capital efficiently. In particular, we look for strong
    free cash flow, because this gives a company the flexibility to do things
    like share buybacks, reinvest in the business, make acquisitions, and
    raise dividends. Finally, we try to assess not only the potential price
    gains for each stock but also the potential for a decline in price if
    things go wrong, and favor those stocks with the highest upside relative
    to their downside.

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

Q:  Could you characterize the global equity markets over the period?


A:  Global equity markets in the aggregate enjoyed positive returns over the
    period, driven by strong returns over the first five months. Markets
    declined sharply during the final week of February erasing the gains
    achieved in January. The drop began with a sharp decline in Chinese
    equities, based on rumors that the government would seek to tighten stock
    market investment rules and introduce a capital gains tax. The release of
    some weaker-than-expected U.S. economic data and evidence of mounting
    problems in the sub-prime U.S. mortgage market further added to a sense
    of unease among investors. As equity markets weakened, the Japanese yen
    rose strongly against the U.S. dollar, which suggested that the
    broad-based decline in equities was partially due to the unwinding of
    so-called carry trades funded through borrowing at low Japanese interest
    rates.


    European equities outperformed both U.S. and Japanese equities in the
    period, helped by the strength of the euro relative to the U.S. dollar.
    From a sector perspective, the strongest areas in the global equity
    markets were telecommunication services, materials and consumer
    discretionary stocks, while the weakest returns were in the energy and
    healthcare sectors.


Q:  What strategies or holdings helped and hurt performance over the period?


A:  While the Fund provided solid positive returns over the period, it modestly
    lagged the benchmark. Unrewarding stock selection within the consumer,
    pharmaceutical and technology hardware areas were the principal factors
    in the underperformance. Within consumer durables, our holdings in
    Japanese homebuilders Sekisui Chemical and Daito Trust Construction
    detracted from returns as they reported weaker-than-expected orders in
    November. Sporting goods maker Adidas proved a drag on returns after
    lowering its 2007 profit guidance due to plans to increase spending on
    its Reebok brand. In pharmaceuticals, our positions in AstraZeneca and
    Pfizer were the key sources of underperformance. AstraZeneca endured a
    weak quarter after it cancelled in October further development of a new
    drug designed to treat stroke victims and subsequently lost patent
    protection on an ulcer


                                                                               5

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

    drug in Europe. Shares in U.S.-based Pfizer dropped sharply in December
    after it stopped development on a new cholesterol drug designed to replace
    its leading drug Lipitor upon expiration of its patent. Finally,
    technology hardware holding Samsung Electronics was a source of weakness.


    On the positive side of the ledger, strong stock selection within capital
    goods helped performance. Deere rose on evidence that demand from overseas
    markets for its agricultural equipment was strengthening, as well as on
    its ability to pass along price increases. Elsewhere in the capital goods
    sector, our holding in German industrials group Siemens performed
    strongly. Its results have exceeded market expectations and investor
    sentiment was further buoyed by the decision to divest its VDO automotive
    unit through an initial public offering. Finally, within automobiles/
    components, our position in Porsche aided returns. Results for Porsche
    were strongly ahead on a year-over-year basis thanks to higher sales
    volumes on its 911 and Cayman models, a more profitable product mix and
    cost savings driven by efficiency gains. The company's outlook for 2007
    appears positive notwithstanding an expected slowdown in U.S. demand.


Q:  What is your outlook and how is it reflected in the Fund?


A:  We continue to be positioned relatively cautiously in recognition of the
    challenges faced by global equity markets. In recent months, further
    evidence has emerged that the U.S. economy is slowing, weighed down in
    part by a significant decline in residential homebuilding activity.
    Inflation has continued to moderate aided by falling energy prices.
    Turning abroad, both the European and U.K. central banks remain wary
    about the upside risks to inflation posed by strong rates of economic
    growth. In Japan, economic growth has been less consistent.


    While equities in the aggregate continue to appear reasonably valued, we
    believe the potential for earnings to disappoint at the individual company
    level remains significant. Thus our focus is on holding companies where
    valuations are reasonable and earnings expectations are likely to be met.
    In this respect, we continue to see more opportunities among larger
    companies and in areas such as consumer staples and pharmaceuticals, where
    valuations have the potential to be impacted positively as interest rates
    peak.

Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

    Going forward, we will continue to look globally for stocks that we
    believe are both reasonably priced and positioned to benefit from the
    underlying company's growth and efficient use of capital.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
Investments in mid-sized companies may offer the potential for higher returns,
but are also subject to greater short-term price fluctuations than larger, more
established companies. The Fund is non-diversified and invests in a limited
number of securities and, as a result, the Fund's performance may be more
volatile than the performance of funds holding more securities. 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
and sectors.

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 net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please 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 Morgan Stanley Capital International (MSCI) World Index measures the
performance of stock markets in the developed world. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly

Pioneer Global Select Equity Fund

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
     and redemption fees.

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 During Period*              $    6.74    $   11.39     $   11.38


*  Expenses are equal to the Fund's annualized expense ratio of 1.30%, 2.20% and
   2.20% for Class A, Class B and Class C shares, respectively, multiplied by
   the average account value over the period, multiplied by 181/365 (to
   reflect the period since inception).


                                                                              13

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) or redemption fees 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.

   the average account value over the period, multiplied by 181/365 (to

1. Organization and Significant Accounting Policies

Pioneer Global Select Equity Fund (the Fund), is one of three portfolios
comprising Pioneer Series Trust V, a Delaware statutory business trust
registered under the Investment Company Act of 1940 an open-end management
investment company. The Fund is non-diversified. The Fund was organized on
October 12, 2005, and commenced operations on December 15, 2005. Prior to
October 12, 2005, the Fund had no operations other than those relating to
organizational matters and the initial capitalization of the Fund by Pioneer
Funds Distributor, Inc. (PFD). The fund's investment objective is to seek
long-term capital growth.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
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 and sectors. Information regarding the Fund's principal risk is
contained in the Fund's prospectus(es). Please refer to those documents when
considering the Fund's risks.

The Fund offers three classes of shares - Class A, Class B and Class C 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 has exclusive voting rights with respect to the
distribution plans that have been adopted by Class A, Class B and Class C
shareowners, respectively.

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 gain or loss on investments during the
reporting periods. 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


                                                                              27


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited) (continued)
- --------------------------------------------------------------------------------

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 are valued using 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 using 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. The Fund invests primarily
    in securities of non-U.S. issuers. The principal exchanges and markets for
    such securities have closing times prior to the close of the NYSE.
    However, the value of these securities may be influenced by changes in
    global markets occurring after the closing times of the local exchanges
    and markets up to the time the Fund determines its net asset value.
    Consequently, the Board of Trustees of the Fund has determined that the
    use of daily fair valuations as provided by a pricing service is
    appropriate for the Fund. The Fund may also take into consideration other
    significant events in determining the fair value of these securities.
    Thus, the Fund's securities valuations may differ from prices reported by
    the various local exchanges and markets. Temporary cash investments are
    valued at amortized cost.

    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 Fund becomes aware 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, 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.

    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.

    The tax character of current year distributions payable will be determined
    at the end of the current fiscal year. There were no distributions paid by
    the Fund during the period ended August 31, 2006.

    The following shows the components of distributable earnings on a federal
    income tax basis at August 31, 2006.



- -------------------------------------------------------------------------------
                                       2006
- --------------------------------------------------------------------------------
                                 
  Undistributed ordinary income     $ 49,303
  Unrealized appreciation             82,698
                                    --------
    Total                           $132,001
                                    ========
- -------------------------------------------------------------------------------



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

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 $634 in underwriting commissions on the sale
    of Class A shares during the six months ended February 28, 2007.


                                                                              29

NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited) (continued)
- --------------------------------------------------------------------------------

D.  Foreign Currency Translation

    The books and records of the Fund are maintained in U.S. dollars. Amounts
    denominated in foreign currencies are translated into U.S. dollars using
    current exchange rates. Net realized gains and losses on foreign currency
    transactions, if any, represent, among other things, the net realized
    gains and losses on foreign currency contracts, disposition of foreign
    currencies and the difference between the amount of income accrued and the
    U.S. dollars actually received. Further, the effects of changes in foreign
    currency exchange rates on investments are not segregated in the statement
    of operations from the effects of changes in market price of those
    securities but are included with the net realized and unrealized gain or
    loss on investments.

E.  Forward Foreign Currency Contracts

    The Fund enters into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date as a hedge or cross-hedge against either specific investment
    transactions (settlement hedges) or portfolio positions (portfolio
    hedges). All contracts are marked to market daily at the applicable
    exchange rates, and any resulting unrealized gains or losses are recorded
    in the Fund's financial statements. The Fund records realized gains and
    losses at the time a portfolio hedge is offset by entry into a closing
    transaction or extinguished by delivery of the currency. Risks may arise
    upon entering into these contracts from the potential inability of
    counterparties to meet the terms of the contract and from unanticipated
    movements in the value of foreign currencies relative to the U.S. dollar.
    At February 28, 2007, the Fund had no outstanding portfolio hedges.

2.  Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary
of UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.75% of the Fund's average daily net
assets up to $500 million; 0.70% of the next $500 million and 0.65% of the
excess over $1 billion. For the six months ended February 28, 2007, the net
management fee was equivalent to 0.75% of the average daily net assets.

PIM has agreed not to impose all or a portion of its management fee and to
assume other operating expenses of the Fund to the extent


30


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

necessary to limit the Fund's expenses to 1.30%, 2.20% and 2.20% of the average
daily net assets attributable to Class A, Class B and Class C shares,
respectively. These expense limitations are in effect through January 1, 2009
for Class A and through January 1, 2008 for Class B and Class C shares.

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 February 28, 2007, $63 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.

3. Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (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 $8,499 in transfer agent fees payable to PIMSS
at February 28, 2007.

4. Distribution Plans and Service Plans

The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the
Investment Company Act of 1940. The Fund pays PFD a service fee of up to 0.25%
of the 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 $53 in distribution fees payable to
PFD at February 28, 2007

In addition, redemptions of each class of 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 4.00% 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%.


                                                                              31


Pioneer Global Select Equity Fund

NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited) (continued)
- --------------------------------------------------------------------------------

Proceeds from the CDSCs are paid to PFD. For the six months ended February 28,
2007, CDSCs in the amount of $156 were paid to PFD.

5. New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than June 29, 2007. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In addition, 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.

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
- --------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees"), voting
separately, annually approve the Fund's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract: (i) will
enable the Fund to receive quality investment advisory services at a fee deemed
reasonable; and (ii) is in the best interests of the Fund and its shareowners.
In making such determinations, the Independent Trustees relied upon the
assistance of counsel to the Independent Trustees and counsel to the Fund.

Throughout the year, the Independent Trustees regularly met in executive
session, separately from the Interested Trustees of the Fund and any officer of
Pioneer Investment Management, Inc., the Fund's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Interested
Trustees, act on all major matters relating to the Fund, a significant portion
of the activities of the Board of Trustees (including certain of those
described herein) is conducted through committees, the members of which are
comprised exclusively of Independent Trustees. Such committee meetings are
attended by officers of the Fund and/or officers of the Investment Adviser to
the extent requested by the members of the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and also
relied upon their knowledge, resulting from their meetings throughout the year,
of the Investment Adviser, its services and the Fund. Both in meetings
specifically dedicated to renewal of the Management Contract and at other
meetings during the course of the year, the Trustees, including the Independent
Trustees, received materials relating to the Investment Adviser's investment
and management services under the Management Contract. These materials included
information on (i) the investment performance of the Fund, a peer group of
funds as classified by Morningstar, Inc., an independent evaluation service
("Morningstar") and an index considered appropriate by the Independent Trustees
for this purpose, (ii) sales and redemption activity in respect of the Fund,
(iii) the general investment outlook in the markets in which the Fund invests,
(iv) arrangements in respect of the distribution of the Fund's shares, (v) the
procedures employed to determine the value of each of the Fund's assets, (vi)
the Investment Adviser's management of the


                                                                              33


Pioneer Global Select Equity Fund

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT                                  (continued)

relationships with the Fund's unaffiliated service providers, (vii) the record
of compliance with the Fund's investment policies and restrictions and with the
Fund's Code of Ethics and the structure and responsibilities of the Investment
Adviser's compliance department and (viii) the nature, cost and character of
non-investment management services provided by the Investment Adviser and its
affiliates.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested, and the Investment
Adviser provided, additional information in order to evaluate the quality of
the Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one year period for the Fund and a
peer group of funds selected on the basis of criteria considered appropriate by
the Independent Trustees for this purpose, (2) management and other fees
incurred by a peer group of funds selected on the basis of criteria considered
appropriate by the Independent Trustees for this purpose, (3) the advisory fees
of comparable portfolios of other clients of the Investment Adviser, (4)
expense ratios for the Fund and a peer group of funds selected on the basis of
criteria considered appropriate by the Independent Trustees for this purpose,
(5) the overall organization of the Investment Adviser, (6) the Investment
Adviser's financial results and condition, including its and certain of its
affiliates' profitability in providing services to the Fund, (7) transfer
agency fees and administrative reimbursements paid to the Investment Adviser or
affiliates, (8) investment management staffing, and (9) operating expenses paid
by the Funds to third parties. The Trustees also reviewed information regarding
the potential for each of the Fund and the Investment Adviser to benefit from
further economies of scale in the management of the Fund in light of reasonable
growth expectations for the Fund and certain of the Fund's expenses that are
incurred on a basis other than as a percentage of net assets.

The following summarizes factors considered by the Trustees in connection with
reviewing the information described above and their renewal of the Fund's
Management Contract. The Trustees did not identify any single factor as
all-important or controlling, and the summary does not detail all the matters
that were considered.


34


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

A.  Ancillary Benefits to Shareowners. The Trustees considered the benefits to
    shareowners of investing in a Fund that is part of a large number of
    investment companies offering a variety of investment disciplines and
    providing for a large variety of Fund and shareowner services.

B.  Compliance and Investment Performance. The Trustees determined that the
    Investment Adviser had policies and systems reasonably designed to achieve
    compliance with the Fund's investment objective and regulatory
    requirements. The Trustees also reviewed the Fund's absolute investment
    performance based upon total return, as well as the Fund's performance
    relative to the performance of both a peer group and an index considered
    appropriate by the Independent Trustees for this purpose. The Fund's
    performance, based upon total return, was in the first quintile of its
    Morningstar category peer group for the period ended June 30, 2006. (In
    all quintile rankings referred to throughout this discussion first
    quintile is most favorable to the Fund's shareowners. Thus, highest
    relative performance would be first quintile and lowest relative expenses
    also would be first quintile.) The Trustees concluded that the performance
    of the Fund was strong during the short period since its inception.

C.  The Investment Adviser's Personnel and Methods. The Trustees reviewed the
    background of members of the team responsible for the daily management of
    the Fund and the Fund's investment objective and discipline. The
    Independent Trustees also have had discussions with senior management of
    the Investment Adviser responsible for investment operations and the
    senior management of the Investment Adviser's equities group. Among other
    things, the Trustees considered the size, education and experience of the
    Investment Adviser's investment staff and their use of technology and
    emphasis on analytics in view of the risk profile of securities in which
    the Fund invests. The Trustees concluded that the Investment Adviser had
    the quality and depth of personnel and the well-developed methods
    essential to perform its duties under the Management Contract.

D.  Nature and Quality of Other Services. The Trustees considered the nature,
    quality and extent of other services provided to shareowners of the Fund,
    including administrative and shareowner services performed by the
    Investment Adviser under the Management


                                                                              35


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------
FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT                                  (continued)
- --------------------------------------------------------------------------------

    Contract. The Trustees also considered the reasonableness of the
    arrangements for reimbursement of the Investment Adviser's out-of-pocket
    costs and expenses, including overhead, for certain administrative
    services that the Investment Adviser is not required to provide under the
    Management Contract. The Trustees also considered the nature and extent of
    the other services provided by the Investment Adviser or its affiliates
    under other contracts, as well as the Investment Adviser's supervision of
    third party service providers. Based on these considerations, the Trustees
    concluded that the nature, quality and extent of such services are
    satisfactory and reliable and serve the shareowners of the Fund well.

E.  Management Fee and Expenses. The Trustees considered the Investment
    Adviser's fee under the Management Contract relative to the management
    fees charged by its Morningstar category peer group. The Fund's management
    fee for the period ended June 30, 2006 was in the second quintile relative
    to the management fees paid by the other funds in that peer group for the
    comparable period. The Trustees also considered the Fund's expense ratio
    for the period ended June 30, 2006 and expense ratios for the comparable
    period of the peer group of funds selected on the basis of criteria
    considered appropriate by the Independent Trustees for this purpose using
    data provided by Strategic Insight Mutual Fund Research and Consulting,
    LLC, an independent third party. The Trustees found the Fund's expense
    ratio for the period ended June 30, 2006 to be in the first quintile,
    according to data for the applicable peer group for the most recent fiscal
    year.

F.  Profitability. The Trustees considered the level of the Investment
    Adviser's profits with respect to the management of the Pioneer Funds,
    including a review of the Investment Adviser's methodology in allocating
    certain of its costs to the management of each Fund, as well as the
    financial results realized by the Investment Adviser in connection with
    the operation of the Fund. They further considered the profits realized by
    the Investment Adviser and its affiliates from non-fund businesses that
    may benefit from or be related to the Fund's business. The Trustees
    considered the Investment Adviser's profit margins in comparison with the
    limited industry data available. The Trustees concluded that the
    Investment Adviser's profits from management of the Pioneer Funds,
    including the financial results derived from the Fund, bear a reasonable
    relationship to the services rendered and are fair for the management of
    the Fund.


36


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

G.  Economies of Scale. The Trustees considered the economies of scale with
    respect to the management of the Fund, whether the Fund had appropriately
    benefited from any economies of scale, and whether there was potential for
    realization of any further economies of scale. The Trustees concluded that
    in light of anticipated growth of the Fund, break points in the management
    fee were not necessary at this time. However, the Trustees would evaluate
    the need for break points from time to time.

H.  Other Benefits to the Investment Adviser. The Trustees also considered the
    character and amount of fees paid by the Fund, other than under the
    Management Contract, for services provided by the Investment Adviser and
    affiliates, including fees for services such as shareowner services. The
    Trustees also considered the receipt of sales loads and payments under
    Rule 12b-1 plans in respect of the Pioneer Funds (including the Fund), and
    benefits to the Investment Adviser from the use of "soft" commission
    dollars to pay for research services. The Trustees further considered the
    revenues and profitability of the Investment Adviser's businesses other
    than the fund business, including the Investment Adviser's institutional
    investment advisory business. The Trustees considered the intangible
    benefits that accrue to the Investment Adviser and its affiliates by
    virtue of its relationship with the Fund and the Pioneer Funds as a group.
    The Trustees concluded that all these types of benefits accruing to the
    Investment Adviser were reasonable in the context of the overall
    relationship between the Investment Adviser and the Fund.

Conclusion. In light of the Investment Adviser's overall performance, the
Trustees considered it appropriate to continue to retain the management
services of the Investment Adviser. Based on their review of the overall nature
and quality of services provided by the Investment Adviser and the fees charged
by other funds in the Fund's relevant peer group, and taking into account all
material factors deemed relevant by the Trustees as well as the advice of
independent counsel, the Trustees concluded that the Management Contract with
the Fund, including the fee payable thereunder, was fair and reasonable and
that its renewal was in the best interests of the Fund and its shareholders.
Accordingly, the Trustees voted to approve the continuation of the Management
Contract for another year.


                                                                              37

Dear Shareowner,
- --------------------------------------------------------------------------------
Welcome to Pioneer. We thank you for your investment in Pioneer Oak Ridge All
Cap Growth Fund and are pleased to provide you with the Fund's first
shareholder report since its inception on October 17, 2006. In managing the
Pioneer Oak Ridge All Cap Growth Fund, we seek to identify what we believe are
the "best of the best" from the three portfolios in order to create a fund of
about 40-60 stocks in the growth universe. In an interview on page 6 of this
report, Lead Portfolio Manager Robert McVicker, discusses the investment
strategies used over the abbreviated fiscal period since October 17, 2006.

As the global economy reacted to good and bad news of 2006, overall it managed
to keep chugging along with fairly stable growth. Looking back, the economic
stories included slowing economic growth bringing monetary tightening to an end
in the United States, price action in oil and other commodity markets
threatening to unsettle global growth and inflation, geopolitical uncertainties
and corporate earnings growth surpassing market expectations.

Global growth surpassed most analyst expectations in 2006. The International
Monetary Fund estimates world output increased by 5.1% in 2006, up from 4.9% in
2005 and above the 3.7% average annual pace of growth of the previous 20 years.
Growth is estimated to slow modestly in 2007 but to remain well above the
long-term average.

U.S. economic growth slowed gradually over 2006, with full-year growth of GDP
of 3.1%, modestly below 2005 growth but still strong enough to lower the
unemployment rate to 4.5%. While many observers were concerned that a weakening
housing sector could be a drag on consumer spending, the consumer has shown
resilience supported by a strong labor market and associated income growth and
by oil and gasoline prices falling from record highs in the second half of
2006. Corporate America has also proved resilient in the face of the slowing
housing sector, with business investment growing at its fastest rate since
2000.

The Federal Reserve stopped increasing interest rates in mid-2006, but has
retained its bias to tighten rates, reflecting upside risks to inflation,
particularly from the tight labor market, and confidence that the economy
remained on solid ground. Consumers welcomed the relief from oil prices that
peaked at mid-year and fell sharply towards year-end. Likewise, in the second
half of 2006, they benefited from the modest easing of core inflation (which
excludes energy and food items), though such core inflation remains above what
is generally considered the central bank's "comfort zone."

The European economy surpassed many economists' expectations in 2006. Eurozone
GDP grew at a 3% pace, much stronger than its 1.8% average annual growth pace
since 2000. Underlying this strength has been buoyant and broad-based strength
in business sentiment and investment and in exports. While household
consumption showed mixed results, the unemployment rate fell to 7.7% by the end
of 2006. The European Central Bank raised interest rates gradually to 3.5% over
the course of 2006, reflecting firm economic growth, steadily tightening labor
market conditions, and fast growing money supply. Core inflation in the
Eurozone remains reasonably benign, at roughly 1.5% per annum. European stock
markets posted strong returns; appreciation of the Euro relative to both the
dollar and Yen made the Eurozone stock market the top performer of 2006.

The Japanese economy continued to grow firmly in 2006. Business investment was
the major driver of expansion as increasing capacity utilization and better

sentiment encouraged a new wave of investment. As deflation ended, the Bank of
Japan ended its zero interest rate policy, although it has raised rates to only
0.25% in 2006. After a strong showing in 2005, the Japanese stock market posted
only muted gains in 2006.

Emerging economies enjoyed strong, relatively uninterrupted economic growth in
2006. Good financing conditions, buoyant commodity prices, which boosted income
and investment in commodity exporting countries, and strong export demand from
developed economies drove this growth. The emerging market stock index was very
strong in early 2006, sold off to near start-of-year levels, then rallied to
finish the year only marginally behind the Eurozone. We believe similar growth
can be expected in the emerging markets if current domestic economic and
political conditions prevail.

While global economic momentum has started to slow, we expect the global
economy to continue growing firmly in 2007, supported by business investment,
rising employment, and lower energy prices. A slowdown in the U.S. growth rate
would be welcome, since rapid growth could increase the risk of inflationary
pressures, which would force the Federal Reserve to raise interest rates. We
expect Europe and Japan to grow similarly, while emerging market economies are
expected to continue their strong growth. In this scenario, fixed-income assets
are expected to produce total returns generally in line with their current
yields, while equities are expected to produce returns generally in line with
earnings growth, which we forecast to be moderately above bond yields.

Our cautiously optimistic outlook on most regions of the world and asset
classes reinforces the importance of Pioneer Investments' message that
investors should remain diversified, take a long-term view rather than
over-reacting to breaking news, and base investment decisions on economic and
market fundamentals rather than on emotion. Our investment philosophy and
approach continue to be based on the use of fundamental research to identify a
range of opportunities that offer an attractive balance of risk and reward to
help Fund shareowners work toward achieving their long-term goals.

Respectfully,


/s/John F. Cogan, Jr.

Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 2/28/07
- --------------------------------------------------------------------------------

In the following interview, Robert McVicker, Pioneer Oak Ridge All Cap Growth
Fund's Lead Portfolio Manager, discusses the factors that influenced
performance during the period from the Fund's inception date of October 17,
2006 through February 28, 2007.

Q:   How did the market and the Fund perform during the reporting period?

A:   Despite a downturn in the final week of February, the market backdrop was
     exceptionally favorable during the four-plus months since we started the
     Fund. The US economy continued to grow at a steady pace, yet with a low
     enough level of inflation to dissuade the Federal Reserve Board from
     raising interest rates. Strength in corporate earnings continued to support
     the market as well: the fourth quarter of 2006 marked the fourteenth
     consecutive quarter of double-digit profit growth for US companies. Adding
     a further spark to the rally was the high level of liquidity in the global
     financial system; or in other words, the large amount of cash available to
     be put to work in the markets. The flood of liquidity fueled a variety of
     positive trends, such as a frenzy of merger and acquisition activity, a
     surge in stock buybacks by corporations, and rising risk appetites among
     investors.

     In this environment, the Fund's Class A shares returned 3.10%,
     outperforming the 3.05% return of its benchmark - the Russell 3000 Growth
     Index.

     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:   How is the Fund managed?

A:   The Fund includes stocks selected from the three portfolios managed by Oak
     Ridge Investments - Pioneer Oak Ridge Large Cap Growth Fund, Pioneer Oak
     Ridge Small Cap Growth Fund, and the mid-cap growth portfolio that we run
     for private accounts. Each of

Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

     these portfolios invests in high-quality, fast-growing, and reasonably
     valued companies within their respective asset classes. The All Cap Growth
     Fund then seeks to identify what we believe are the "best of the best" from
     the three portfolios in order to create a fund of about 40-60 stocks in the
     growth universe. We believe this focused portfolio allows us to reap the
     benefits if our stock selection proves effective, yet at the same time we
     strive to manage risk by maintaining an appropriate level of sector and
     market cap diversification. Our goal is to invest in stocks for the
     long-term, thereby limiting the Fund's portfolio turnover rate.

     In order to select stocks for the Fund, we use three main criteria. First,
     we look for superior companies that are taking market share and forcing
     their competitors to adjust. Second, we invest only in companies with a
     history of consistent earnings growth and a high likelihood of consistent
     future earnings growth. Third, we only buy stocks at valuations that are
     reasonable relative to the company's earnings prospects and fundamentals.
     For instance, we will only buy a stock if its price-to-earnings ratio is no
     more than two times its growth rate.

     We believe this extensive filtration process, along with our flexibility to
     select stocks across all market capitalizations in order to find the best
     investment ideas, will hold the Fund's shareholders in good stead over
     time.

Q:   What factors helped performance during the abbreviated reporting period?

A:   The Fund benefited from our stock selection in the energy sector, where two
     natural gas drillers - XTO Energy (a large cap) and Southwestern Energy (a
     mid cap) both outperformed their industry peers by a wide margin. We also
     generated outperformance in the industrials and technology sectors.

     The top individual contributor was Cognizant Technology Solutions, which as
     a provider of information technology (IT) outsourcing services has
     benefited greatly from US companies' growing propensity to move elements of
     their IT functions to India in order to reduce costs. Precision Castparts
     also was a strong performer for the Fund. A manufacturer of highly
     engineered airplane parts, the company has capitalized on both growing
     demand from the emerging markets as well as airlines' need to replace
     planes in

                                                                               5

     their aging fleets. The third-best contributor was Stericycle, which as the
     largest player in the tightly-regulated hospital waste services industry
     has been able to both gain market share and exercise pricing power with its
     customers. In addition, the company's contract-based business has enabled
     it to deliver consistent and reliable earnings growth over time. Rounding
     out the list of top contributors was Marriott International, which has
     delivered rising earnings on the strength of increased corporate spending
     on business travel.

Q:   What elements of the Fund's positioning detracted from performance?

A:   The Fund's holdings in the materials sector underperformed. Our avoidance
     of cyclical stocks weighed on relative performance at a time when sectors
     such as aluminum, steel and metals surged. Our stock picks in the consumer
     discretionary sector also underperformed, the result of the Fund's lack of
     a position in the specialty retailers group. The best performers in this
     segment were the teen retailers, but we avoid this area on the basis that
     even the best fundamental stock research will not be able accurately to
     predict teen fashion trends. We focused instead on steadier businesses such
     as Gamestop, which sells new and used video games; O'Reilly Automotive,
     which provides auto parts and services to the commercial and retail
     markets; and Staples, which - like Marriott - is positioned to take
     advantage of the continued strength in corporate spending. While by no
     means cutting-edge, these businesses represent the type of stable growers
     in which we prefer to invest.

     Among the most significant individual detractors from performance was
     Sallie Mae, the student loan provider that is facing increased political
     headwinds in the form of the new Congressional inquiries. Believing this
     development reduced the visibility regarding the company's growth outlook,
     we elected to sell the position. Also detracting was East/West Bancorp, a
     small-cap bank with a focus on the Asian market on the West Coast. The
     company's earnings were pressured by the decline in long-term interest
     rates relative to short-term rates, a development that resulted in
     declining margins between the rate it can earn on loans versus what it pays
     out on deposits. As with Sallie Mae, the cloudier outlook for East/West's
     earnings prompted us to eliminate the stock from the portfolio.

Q:   What is your outlook for growth stocks?

A:   As the reporting period drew to a close, investor psychology seemed to be
     characterized by a great deal of caution regarding the outlook for the rest
     of this year. In contrast to that consensus view, we are fairly optimistic.
     Despite superior earnings, growth stocks remain at historically low
     valuation levels relative to traditional "value" stocks. In addition, we
     believe decelerating profit growth for the overall market will lead to
     rising investor demand for stocks that can produce reliable growth.
     Specifically, we believe companies that can deliver earnings via strong
     top-line sales growth, and not just cost-cutting, will become increasingly
     attractive to investors.

     With that as a backdrop, we will be looking to take advantage of market
     volatility to purchase stocks whose valuations have declined to attractive
     levels. Our investment style can be characterized as "growth at a
     reasonable price," or GARP, strategy. While growth has been relatively easy
     to find in recent years, the "reasonable price" element of the equation has
     been more difficult. We are optimistic that rising risk aversion among
     investors will bring a larger number of stocks into our buy zone as the
     year progresses.

     Thank you for your interest in Pioneer Oak Ridge All Cap Growth Fund. We
     look forward to the opportunity to communicate regularly with shareholders
     in the months and years ahead.

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.

POP returns reflect deduction of maximum 5.75% sales charge. NAV 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.

Some expenses are based on estimated amounts for the current fiscal year.

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 net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please 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.

*    Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%,
     and 2.06%, for Class A, Class C and Class Y shares, respectively,
     multiplied by the average account value over the period, multiplied by
     135/365 (to reflect the partial year period).

                                                                              13

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.

NOTES TO FINANCIAL STATEMENTS 2/28/07 (unaudited)

1.   Organization and Significant Accounting Policies

Pioneer Oakridge All Cap Growth Fund (the Fund) is one of five series of
portfolios comprising Pioneer Series Trust V, 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 capital
appreciation.

The Fund offers three classes of shares - Class A, Class C and Class Y shares.
Class A and Class C shares were first publicly offered on October 17, 2006. 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 C and Class Y 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 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 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

26


Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

     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 February 28, 2007, there
     were no securities fair valued. Temporary cash investments are valued at
     amortized cost.

     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 exercise of reasonable diligence. Dividend and interest income is
     recorded on the accrual basis, 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.

     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.

     The tax character of current year distributions paid will be determined at
     the end of the current fiscal year.

                                                                              27

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 approximately $8 in underwriting commissions
     on the sale of Class A shares for the period ended February 28, 2007.


D.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, and Class C shares of the Fund, respectively (see
     Note 4). 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 each class of shares
     based on the 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, on the same day, and in
     the same amount, except that Class A, Class C, and Class Y shares bear
     different transfer agent and distribution fees.


2.   Management Agreement

PIM, a wholly owned subsidiary of UniCredito Italino, manages the Fund's
portfolio. PIM receives a basic fee that is calculated at the annual rate of
0.75% of the Fund's average daily net assets up to $500 million; and 0.70% on
assets over $500 million. The management fees were equivalent to 0.75% of the
average daily net assets for the period.

Pioneer has contractually agreed to limit ordinary operating expenses to the
extent required to reduce Fund expenses to 1.25% and 2.15% of the average daily
net assets attributable to Class A and Class C shares, respectively. These
expense limitations are in effect through

28


Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

January 1, 2009 for Class A shares and through January 1, 2008 for Class C
shares. There is no expense limitation in effect for Class Y shares.

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. On February 28, 2007, there were no management
fees, administrative costs or other services payable to PIM.


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 $454 in transfer agent fees
payable to PIMSS at February 28, 2007.


4.   Distribution and Service Plan

The Fund adopted a Plan of Distribution for Class A and Class C shares (Class A
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 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 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 C
shares. Included in due to affiliates is $14 in distribution fees payable to PFD
at February 28, 2007.

In addition, redemptions of Class A and Class C 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. 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
period ended February 28, 2007, no CDSCs were paid to PFD.

                                                                              29

5.   Expense Offset Arrangements

The Fund has entered into an expense offset arrangement with PIMSS resulting in
a reduction in the Fund's total expenses due to interest earned on cash held by
PIMSS. For the period ended February 28, 2007, the Fund's expenses were not
reduced under such arrangement.


6.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than June 29, 2007. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In addition, 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.

Dear Shareowner,
- --------------------------------------------------------------------------------
As the global economy reacted to good and bad news of 2006, overall it managed
to keep chugging along with fairly stable growth. Looking back, the economic
stories included slowing economic growth bringing monetary tightening to an end
in the United States, price action in oil and other commodity markets
threatening to unsettle global growth and inflation, geopolitical uncertainties
and corporate earnings growth surpassing market expectations.

Global growth surpassed most analyst expectations in 2006. The International
Monetary Fund estimates world output increased by 5.1% in 2006, up from 4.9% in
2005 and above the 3.7% average annual pace of growth of the previous 20 years.
Growth is estimated to slow modestly in 2007 but to remain well above the
long-term average.

U.S. economic growth slowed gradually over 2006, with full-year growth of GDP of
3.1%, modestly below 2005 growth but still strong enough to lower the
unemployment rate to 4.5%. While many observers were concerned that a weakening
housing sector could be a drag on consumer spending, the consumer has shown
resilience supported by a strong labor market and associated income growth and
by oil and gasoline prices falling from record highs in the second half of 2006.
Corporate America has also proved resilient in the face of the slowing housing
sector, with business investment growing at its fastest rate since 2000.

The Federal Reserve stopped increasing interest rates in mid-2006, but has
retained its bias to tighten rates, reflecting upside risks to inflation,
particularly from the tight labor market, and confidence that the economy
remained on solid ground. Consumers welcomed the relief from oil prices that
peaked at mid-year and fell sharply towards year-end. Likewise, in the second
half of 2006, they benefited from the modest easing of core inflation (which
excludes energy and food items), though such core inflation remains above what
is generally considered the central bank's "comfort zone."

The European economy surpassed many economists' expectations in 2006. Eurozone
GDP grew at a 3% pace, much stronger than its 1.8% average annual growth pace
since 2000. Underlying this strength has been buoyant and broad-based strength
in business sentiment and investment and in exports. While household consumption
showed mixed results, the unemployment rate fell to 7.7% by the end of 2006. The
European Central Bank raised interest rates gradually to 3.5% over the course of
2006, reflecting firm economic growth, steadily tightening labor market
conditions, and fast growing money supply. Core inflation in the Eurozone
remains reasonably benign, at roughly 1.5% per annum. European stock markets
posted strong returns; appreciation of the Euro relative to both the dollar and
Yen made the Eurozone stock market the top performer of 2006.

The Japanese economy continued to grow firmly in 2006. Business investment was
the major driver of expansion as increasing capacity utilization and better
sentiment encouraged a new wave of investment. As deflation ended, the Bank of
Japan ended its zero interest rate policy, although it has raised rates to only
0.25% in 2006. After a strong showing in 2005, the Japanese stock market posted
only muted gains in 2006.

Emerging economies enjoyed strong, relatively uninterrupted economic growth in
2006. Good financing conditions, buoyant commodity prices, which boosted income
and investment in commodity exporting countries, and strong export demand from
developed economies drove this growth. The emerging market stock

index was very strong in early 2006, sold off to near start-of-year levels, then
rallied to finish the year only marginally behind the Eurozone. We believe
similar growth can be expected in the emerging markets if current domestic
economic and political conditions prevail.

While global economic momentum has started to slow, we expect the global economy
to continue growing firmly in 2007, supported by business investment, rising
employment, and lower energy prices. A slowdown in the U.S. growth rate would be
welcome, since rapid growth could increase the risk of inflationary pressures,
which would force the Federal Reserve to raise interest rates. We expect Europe
and Japan to grow similarly, while emerging market economies are expected to
continue their strong growth. In this scenario, fixed-income assets are expected
to produce total returns generally in line with their current yields, while
equities are expected to produce returns generally in line with earnings growth,
which we forecast to be moderately above bond yields.

Our cautiously optimistic outlook on most regions of the world and asset classes
reinforces the importance of Pioneer Investments' message that investors should
remain diversified, take a long-term view rather than over-reacting to breaking
news, and base investment decisions on economic and market fundamentals rather
than on emotion. Our investment philosophy and approach continue to be based on
the use of fundamental research to identify a range of opportunities that offer
an attractive balance of risk and reward to help Fund shareowners work toward
achieving their long-term goals.

Respectfully,

/s/ JOHN F. COGAN, JR.

Pioneer Select Research Growth Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 2/28/07
- --------------------------------------------------------------------------------

The U.S. stock market registered strong gains during the six months ended
February 28, 2007, supported by a durable economic expansion, growing corporate
profits, modest inflation and a relatively benign interest-rate environment. In
the following interview, members of the team responsible for managing Pioneer
Select Research Growth Fund review the period. Discussing the factors that
affected Fund performance during the six months are: Diego Franzin, Head of
Pioneer's U.S. Quantitative Research & Management Group; Ashesh Savla, a
Quantitative Analyst at Pioneer; and John Peckham, CFA, Head of U.S. Equity
Research at Pioneer.

Q: How did the Pioneer Select Research Growth Fund perform during the six months
   ended February 28, 2007?

A: The Fund performed very well. Class A shares had a total return of 10.38%, at
   net asset value, for the six months. During the same period, the benchmark
   Russell 1000 Growth Index gained 9.54% while the average performance of the
   752 funds in Lipper's Large Cap Growth category was 8.33%.

   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 were the principal factors that affected the Fund's performance during
   the six months?

A: The market environment was very positive. Investors were relieved that the
   Federal Reserve Board decided to pause in its interest-rate-hike cycle, while
   energy prices began receding after rising dramatically before the period.
   Corporations continued to report reasonable profit growth in the face of a
   supportive economic environment of persistent growth, relatively benign
   interest rates and modest inflationary pressures by historical standards.
   Helped by strong employment trends, consumer spending proved to be resilient,
   despite softness in the housing market.

Pioneer Select Research Growth Fund
- --------------------------------------------------------------------------------

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

   Consistent with the management style of the Fund, stock selection drove
   performance, led by holdings in the information technology, industrials and
   consumer discretionary sectors. Our picks in the financials and materials
   sectors tended to be less supportive of performance. We select the Fund's
   approximately 50 holdings from the 100 stocks in the Pioneer Research Fund
   portfolio. Our sector weightings are equal to those of the benchmark Russell
   1000 Growth Index. In our selection process, we rank stocks by using
   quantitative screens based on Pioneer's proprietary analysis of the superior
   characteristics of stocks in 17 different sectors and industries.

Q: What individual investments had the greatest impact on performance, either
   positive or negative?

A: Among our information technology holdings, we had especially good results
   from our positions in Freescale, Sun Microsystems and Apple. Freescale, a
   leading producer of semiconductors used in components of automobiles, mobile
   phones and other devices, received a significant buyout offer from a private
   equity firm. Sun Microsystems began to reap the benefits of its new
   energy-efficient product line for corporate information technology systems.
   Apple, meanwhile, introduced its new iPhone which created another growth
   opportunity for its line of iPod-related devices.

   In the industrials sector, strong performers included railroad company
   Norfolk Southern and equipment manufacturer Terex. Norfolk Southern - a stock
   that we sold before period's end - enjoyed the benefits of a healthy economy
   that created a steady demand for rail shipments. Terex, meanwhile, benefited
   from healthy demand for heavy equipment from its industrial and utility
   customers. In the consumer discretionary sector, our selections in the
   retailing industry performed especially well, led by Target, JC Penney, and
   McDonald's. Target and JC Penney, aided by their strong franchises, generated
   better-than-expected sales. McDonald's continued to benefit from a new menu
   and healthy growth in its international business.

   Among our selections in the financials and materials sectors, performance was
   held back by not owning some of the better-performing companies. For example,
   in financials we had a position in Merrill Lynch, which was less exposed to
   investment


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 2/28/07                              (continued)
- --------------------------------------------------------------------------------

   banking activities such as mergers-and-acquisitions and initial public stock
   offerings. Heavy transaction-related activity led to very strong performance
   by companies such as Goldman Sachs, a company that we did not own. Similarly,
   in the materials sector, we were underweighted in mining and metals
   companies, which were among the top performers.

Q: What is your investment outlook?

A: We see good potential for a continued supportive environment for equities.
   Stock valuations are not high, by historical standards, while the economy
   continues to grow, although at a moderating pace. Inflation and interest
   rates remain moderate by historical standards, and continued heavy
   mergers-and-acquisition activity provides a base of support for equity
   prices. We see the most significant near-term concerns coming from the
   slumping housing industry and the potential fall-out on sub-prime mortgage
   providers. However, we believe strong employment trends, if they persist,
   should give the market to ability to withstand any pressures from the weak
   housing industry.

   Overall, we remain positive about stocks.

Investing in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies. 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. 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 and sectors.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are
statements of the opinion of Fund management as of the date of this report.
These opinions should not be relied upon for any other purposes. Past
performance is no guarantee of future results, and there is no guarantee that
market forecasts discussed will be realized.

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.

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 net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please 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 Russell 1000[RegTM] Growth Index measures the performance of large-cap U.S.
growth stocks. Index returns assume reinvestment of dividends and, unlike Fund
returns, do not reflect any fees, expenses or sales charges. You cannot invest
directly in an Index.

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.

Beginning Account Value On 9/1/06      $1,000.00
Ending Account Value On 2/28/07        $1,103.80
Expenses Paid During Period*           $    6.52


* Expenses are equal to the Fund's annualized expense ratio of 1.25% for Class A
  shares, multiplied by the average account value over the period, multiplied by
  181/365 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS 2/28/07 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Select Research Growth Fund (the Fund) is one of three portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund was organized on October 12, 2005, and commenced
operations on December 15, 2005. Prior to December 15, 2005, the Fund had no
operations other than those relating to organizational matters and the initial
capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). To date, no
shares have been offered to the public. The Fund shares outstanding at February
28, 2007, are owned by PFD. The Fund's investment objective is long-term capital
growth.

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 and sectors. Information regarding the Fund's principal investment
risks is contained in the Fund's prospectus. Please refer to that document when
considering the Fund's investment 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 gain or loss on investments during the reporting periods.
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 are valued at the last sale price on the
   principal exchange where they are traded. Securities that have not traded on
   the date of


                                                                              21


Pioneer Select Research Growth Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited)                   (continued)
- --------------------------------------------------------------------------------

   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. As
   of February 28, 2007, there were no securities fair valued. Temporary cash
   investments are valued at amortized cost.

   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
   exercise of reasonable diligence. Interest income, including interest on
   income bearing cash accounts, is recorded on the accrual basis, 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.

   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.

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

   The tax character of current year distributions paid will be determined at
   the end of the current fiscal year. There were no distributions paid during
   the period ended August 31, 2006.

   The following shows the components of distributable earnings on a federal
   income tax basis at August 31, 2006:

  Unrealized appreciation            7,819

    Total                           $9,115
                                    ======

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

C. 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.

2. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.75% of the Fund's average daily net
assets up to $1 billion and 0.70% on assets over $1 billion. For the six months
ended February 28, 2007, the net management fee was equivalent to 0.75% of the
average daily net assets.


                                                                              23

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited)                   (continued)
- --------------------------------------------------------------------------------

Through January 1, 2009, PIM has agreed not to impose its management fee and to
assume other operating expenses of the Fund to the extent necessary to limit
Class A expenses to 1.25% of the average daily net assets attributable to Class
A shares.

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 February 28, 2007, there were no fees payable
to PIM related to management fees, administrative costs and certain other
services.

3. Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (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 $5,081 in transfer agent fees payable to PIMSS at February 28,
2007.

4. Distribution Plan

The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the
Investment Company Act of 1940. The Fund pays PFD a service fee of up to 0.25%
of the 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. There were no distribution fees payable to PFD at
February 28, 2007.

5. New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than June 29, 2007. At


24


Pioneer Select Research Growth Fund
- --------------------------------------------------------------------------------

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

this time, management is evaluating the implications of FIN 48 and any impact
in the financial statements has not yet been determined.

In addition, 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.


                                                                              25

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
- --------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees"), voting
separately, annually approve the Fund's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract: (i) will
enable the Fund to receive quality investment advisory services at a fee deemed
reasonable; and (ii) is in the best interests of the Fund and its shareowners.
In making such determinations, the Independent Trustees relied upon the
assistance of counsel to the Independent Trustees and counsel to the Fund.

Throughout the year, the Independent Trustees regularly met in executive
session, separately from the Interested Trustees of the Fund and any officer of
Pioneer Investment Management, Inc., the Fund's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Interested
Trustees, act on all major matters relating to the Fund, a significant portion
of the activities of the Board of Trustees (including certain of those described
herein) is conducted through committees, the members of which are comprised
exclusively of Independent Trustees. Such committee meetings are attended by
officers of the Fund and/or officers of the Investment Adviser to the extent
requested by the members of the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and also
relied upon their knowledge, resulting from their meetings throughout the year,
of the Investment Adviser, its services and the Fund. Both in meetings
specifically dedicated to renewal of the Management Contract and at other
meetings during the course of the year, the Trustees, including the Independent
Trustees, received materials relating to the Investment Adviser's investment and
management services under the Management Contract. These materials included
information on (i) the investment performance of the Fund, a peer group of funds
as classified by Morningstar, Inc., an independent evaluation service
("Morningstar") and an index considered appropriate by the Independent Trustees
for this purpose, (ii) sales and redemption activity in respect of the Fund,
(iii) the general investment outlook in the markets in which the Fund invests,
(iv) arrangements in respect of the distribution of the Fund's shares, (v) the
procedures employed to determine the value of each of the Fund's assets, (vi)
the Investment Adviser's management of the


26


Pioneer Select Research Growth Fund
- --------------------------------------------------------------------------------

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

relationships with the Fund's unaffiliated service providers, (vii) the record
of compliance with the Fund's investment policies and restrictions and with the
Fund's Code of Ethics and the structure and responsibilities of the Investment
Adviser's compliance department and (viii) the nature, cost and character of
non-investment management services provided by the Investment Adviser and its
affiliates.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested, and the Investment
Adviser provided, additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one year period for the Fund and a
peer group of funds selected on the basis of criteria considered appropriate by
the Independent Trustees for this purpose, (2) management and other fees
incurred by a peer group of funds selected on the basis of criteria considered
appropriate by the Independent Trustees for this purpose, (3) the advisory fees
of comparable portfolios of other clients of the Investment Adviser, (4) expense
ratios for the Fund and a peer group of funds selected on the basis of criteria
considered appropriate by the Independent Trustees for this purpose, (5) the
overall organization of the Investment Adviser, (6) the Investment Adviser's
financial results and condition, including its and certain of its affiliates'
profitability in providing services to the Fund, (7) transfer agency fees and
administrative reimbursements paid to the Investment Adviser or affiliates, (8)
investment management staffing, and (9) operating expenses paid by the Funds to
third parties. The Trustees also reviewed information regarding the potential
for each of the Fund and the Investment Adviser to benefit from further
economies of scale in the management of the Fund in light of reasonable growth
expectations for the Fund and certain of the Fund's expenses that are incurred
on a basis other than as a percentage of net assets.

The following summarizes factors considered by the Trustees in connection with
reviewing the information described above and their renewal of the Fund's
Management Contract. The Trustees did not identify any single factor as
all-important or controlling, and the summary does not detail all the matters
that were considered.

A. Ancillary Benefits to Shareowners. The Trustees considered the benefits to
   shareowners of investing in a Fund that is part of a


                                                                              27

APPROVING THE MANAGEMENT CONTRACT                                    (continued)
- --------------------------------------------------------------------------------

   large number of investment companies offering a variety of investment
   disciplines and providing for a large variety of Fund and shareowner
   services.

B. Compliance and Investment Performance. The Trustees determined that the
   Investment Adviser had policies and systems reasonably designed to achieve
   compliance with the Fund's investment objective and regulatory requirements.
   The Trustees also reviewed the Fund's absolute investment performance based
   upon total return, as well as the Fund's performance relative to the
   performance of both a peer group and an index considered appropriate by the
   Independent Trustees for this purpose. The Fund's performance, based upon
   total return, was in the second quintile of its Morningstar category peer
   group for the period ended June 30, 2006. (In all quintile rankings referred
   to throughout this discussion first quintile is most favorable to the Fund's
   shareowners. Thus, highest relative performance would be first quintile and
   lowest relative expenses also would be first quintile.) The Trustees
   concluded that the performance of the Fund was good during the short period
   since its inception.

C. The Investment Adviser's Personnel and Methods. The Trustees reviewed the
   background of members of the team responsible for the daily management of the
   Fund and the Fund's investment objective and discipline. The Independent
   Trustees also have had discussions with senior management of the Investment
   Adviser responsible for investment operations and the senior management of
   the Investment Adviser's equities group. Among other things, the Trustees
   considered the size, education and experience of the Investment Adviser's
   investment staff and their use of technology and emphasis on analytics in
   view of the risk profile of securities in which the Fund invests. The
   Trustees concluded that the Investment Adviser had the quality and depth of
   personnel and the well-developed methods essential to perform its duties
   under the Management Contract.

D. Nature and Quality of Other Services. The Trustees considered the nature,
   quality and extent of other services provided to shareowners of the Fund,
   including administrative and shareowner services performed by the Investment
   Adviser under the Management Contract. The Trustees also considered the
   reasonableness of the arrangements for reimbursement of the Investment
   Adviser's


28

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

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

   out-of-pocket costs and expenses, including overhead, for certain
   administrative services that the Investment Adviser is not required to
   provide under the Management Contract. The Trustees also considered the
   nature and extent of the other services provided by the Investment Adviser or
   its affiliates under other contracts, as well as the Investment Adviser's
   supervision of third party service providers. Based on these considerations,
   the Trustees concluded that the nature, quality and extent of such services
   are satisfactory and reliable and serve the shareowners of the Fund well.

E. Management Fee and Expenses. The Trustees considered the Investment Adviser's
   fee under the Management Contract relative to the management fees charged by
   its Morningstar category peer group. The Fund's management fee for the period
   ended June 30, 2006 was in the second quintile relative to the management
   fees paid by the other funds in that peer group for the comparable period.
   The Trustees also considered the Fund's expense ratio for the period ended
   June 30, 2006 and expense ratios for the comparable period of the peer group
   of funds selected on the basis of criteria considered appropriate by the
   Independent Trustees for this purpose using data provided by Strategic
   Insight Mutual Fund Research and Consulting, LLC, an independent third party.
   The Trustees found the Fund's expense ratio for the period ended June 30,
   2006 to be in the first quintile, according to data for the applicable peer
   group for the most recent fiscal year.

F. Profitability. The Trustees considered the level of the Investment Adviser's
   profits with respect to the management of the Pioneer Funds, including a
   review of the Investment Adviser's methodology in allocating certain of its
   costs to the management of each Fund, as well as the financial results
   realized by the Investment Adviser in connection with the operation of the
   Fund. They further considered the profits realized by the Investment Adviser
   and its affiliates from non-fund businesses that may benefit from or be
   related to the Fund's business. The Trustees considered the Investment
   Adviser's profit margins in comparison with the limited industry data
   available. The Trustees concluded that the Investment Adviser's profits from
   management of the Pioneer Funds, including the financial results derived from
   the Fund, bear a reasonable relationship to the services rendered and are
   fair for the management of the Fund.


                                                                              29

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

G. Economies of Scale. The Trustees considered the economies of scale with
   respect to the management of the Fund, whether the Fund had appropriately
   benefited from any economies of scale, and whether there was potential for
   realization of any further economies of scale. The Trustees concluded that in
   light of anticipated growth of the Fund, break points in the management fee
   were not necessary at this time. However, the Trustees would evaluate the
   need for break points from time to time.

H. Other Benefits to the Investment Adviser. The Trustees also considered the
   character and amount of fees paid by the Fund, other than under the
   Management Contract, for services provided by the Investment Adviser and
   affiliates, including fees for services such as shareowner services. The
   Trustees also considered the receipt of sales loads and payments under Rule
   12b-1 plans in respect of the Pioneer Funds (including the Fund), and
   benefits to the Investment Adviser from the use of "soft" commission dollars
   to pay for research services. The Trustees further considered the revenues
   and profitability of the Investment Adviser's businesses other than the fund
   business, including the Investment Adviser's institutional investment
   advisory business. The Trustees considered the intangible benefits that
   accrue to the Investment Adviser and its affiliates by virtue of its
   relationship with the Fund and the Pioneer Funds as a group. The Trustees
   concluded that all these types of benefits accruing to the Investment Adviser
   were reasonable in the context of the overall relationship between the
   Investment Adviser and the Fund.

Conclusion. In light of the Investment Adviser's overall performance, the
Trustees considered it appropriate to continue to retain the management services
of the Investment Adviser. Based on their review of the overall nature and
quality of services provided by the Investment Adviser and the fees charged by
other funds in the Fund's relevant peer group, and taking into account all
material factors deemed relevant by the Trustees as well as the advice of
independent counsel, the Trustees concluded that the Management Contract with
the Fund, including the fee payable thereunder, was fair and reasonable and that
its renewal was in the best interests of the Fund and its shareholders.
Accordingly, the Trustees voted to approve the continuation of the Management
Contract for another year.

Dear Shareowner,
- --------------------------------------------------------------------------------
As the global economy reacted to good and bad news of 2006, overall it managed
to keep chugging along with fairly stable growth. Looking back, the economic
stories included slowing economic growth bringing monetary tightening to an end
in the United States, price action in oil and other commodity markets
threatening to unsettle global growth and inflation, geopolitical uncertainties
and corporate earnings growth surpassing market expectations.

Global growth surpassed most analyst expectations in 2006. The International
Monetary Fund estimates world output increased by 5.1% in 2006, up from 4.9% in
2005 and above the 3.7% average annual pace of growth of the previous 20 years.
Growth is estimated to slow modestly in 2007 but to remain well above the
long-term average.

U.S. economic growth slowed gradually over 2006, with full-year growth of GDP
of 3.1%, modestly below 2005 growth but still strong enough to lower the
unemployment rate to 4.5%. While many observers were concerned that a weakening
housing sector could be a drag on consumer spending, the consumer has shown
resilience supported by a strong labor market and associated income growth and
by oil and gasoline prices falling from record highs in the second half of
2006. Corporate America has also proved resilient in the face of the slowing
housing sector, with business investment growing at its fastest rate since
2000.

The Federal Reserve stopped increasing interest rates in mid-2006, but has
retained its bias to tighten rates, reflecting upside risks to inflation,
particularly from the tight labor market, and confidence that the economy
remained on solid ground. Consumers welcomed the relief from oil prices that
peaked at mid-year and fell sharply towards year-end. Likewise, in the second
half of 2006, they benefited from the modest easing of core inflation (which
excludes energy and food items), though such core inflation remains above what
is generally considered the central bank's "comfort zone."

The European economy surpassed many economists' expectations in 2006. Eurozone
GDP grew at a 3% pace, much stronger than its 1.8% average annual growth pace
since 2000. Underlying this strength has been buoyant and broad-based strength
in business sentiment and investment and in exports. While household
consumption showed mixed results, the unemployment rate fell to 7.7% by the end
of 2006. The European Central Bank raised interest rates gradually to 3.5% over
the course of 2006, reflecting firm economic growth, steadily tightening labor
market conditions, and fast growing money supply. Core inflation in the
Eurozone remains reasonably benign, at roughly 1.5% per annum. European stock
markets posted strong returns; appreciation of the Euro relative to both the
dollar and Yen made the Eurozone stock market the top performer of 2006.

The Japanese economy continued to grow firmly in 2006. Business investment was
the major driver of expansion as increasing capacity utilization and better
sentiment encouraged a new wave of investment. As deflation ended, the Bank of
Japan ended its zero interest rate policy, although it has raised rates to only
0.25% in 2006. After a strong showing in 2005, the Japanese stock market posted
only muted gains in 2006.

Emerging economies enjoyed strong, relatively uninterrupted economic growth in
2006. Good financing conditions, buoyant commodity prices, which boosted income
and investment in commodity exporting countries, and strong export demand from
developed economies drove this growth. The emerging market stock

Letter

index was very strong in early 2006, sold off to near start-of-year levels,
then rallied to finish the year only marginally behind the Eurozone. We believe
similar growth can be expected in the emerging markets if current domestic
economic and political conditions prevail.

While global economic momentum has started to slow, we expect the global
economy to continue growing firmly in 2007, supported by business investment,
rising employment, and lower energy prices. A slowdown in the U.S. growth rate
would be welcome, since rapid growth could increase the risk of inflationary
pressures, which would force the Federal Reserve to raise interest rates. We
expect Europe and Japan to grow similarly, while emerging market economies are
expected to continue their strong growth. In this scenario, fixed-income assets
are expected to produce total returns generally in line with their current
yields, while equities are expected to produce returns generally in line with
earnings growth, which we forecast to be moderately above bond yields.

Our cautiously optimistic outlook on most regions of the world and asset
classes reinforces the importance of Pioneer Investments' message that
investors should remain diversified, take a long-term view rather than
over-reacting to breaking news, and base investment decisions on economic and
market fundamentals rather than on emotion. Our investment philosophy and
approach continue to be based on the use of fundamental research to identify a
range of opportunities that offer an attractive balance of risk and reward to
help Fund shareowners work toward achieving their long-term goals.

Respectfully,
/s/John F. Cogan, Jr

PORTFOLIO MANAGEMENT DISCUSSION 2/28/07
- --------------------------------------------------------------------------------

Stock prices climbed steadily higher during the six months ended February 28,
2007, aided by persistently growing corporate profits, a healthy economy,
moderate inflation and a relatively benign interest-rate environment. In the
following interview, members of the team responsible for managing Pioneer
Select Research Value Fund review the period. Discussing the factors that
affected Fund performance during the six months are: Diego Franzin, Head of
Pioneer's U.S. Quantitative Research & Management Group; Ashesh Savla, a
Quantitative Analyst at Pioneer; and John Peckham, CFA, Head of U.S. Equity
Research at Pioneer.


Q:  How did the Pioneer Select Research Value Fund perform during the six
    months ended February 28, 2007?


A:  The Fund slightly underperformed its benchmark, but outperformed its
    competitive peer group. Class A shares had a total return of 9.65%, at
    net asset value, for the six months. During the same period, the
    benchmark Russell 1000 Value Index gained 9.82%, while the average
    performance of the 515 funds in Lipper's Large Cap Value category was
    8.82%.

    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 were the principal factors that affected the Fund's performance during
    the six months?


A:  We believe the Fund's performance improved significantly during the period
    as the market turned from momentum-driven stocks to shares of
    fundamentally strong corporations. This favorable backdrop helped
    equities produce solid results for the six months. Investors were
    relieved that the Federal Reserve Board decided to pause in its
    interest-rate-hike cycle, while energy prices began receding after rising
    dramatically before the period. Corporations continued to report
    reasonable profit growth in the face of an economic environment of
    persistent growth, relatively benign

    interest rates and modest inflationary pressures by historical standards.
    Helped by strong employment trends, consumer spending proved to be
    resilient, despite softness in the housing market.


    Consistent with the management style of the Fund, stock selection drove
    performance. The best results, relative to our benchmark, were in the
    health care and consumer discretionary sectors. Less successful, however,
    were our choices in the telecommunications services and utilities sectors.
    We select the Fund's approximately 50 holdings from the 100 stocks in the
    Pioneer Research Fund portfolio. Our sector weightings are equal to those
    of the benchmark Russell 1000 Value Index. In our selection process, we
    rank stocks by using quantitative screens based on Pioneer's proprietary
    analysis of the superior characteristics of stocks in 17 different sectors
    and industries.


Q:  What individual investments had the greatest impact on performance, either
    positive or negative?


A:  We had good stock selection in the health care sector, especially in the
    pharmaceutical industry where we held a significant position in
    Bristol-Myers while avoiding Pfizer, a very visible laggard in the
    industry. Investors were attracted to Bristol-Myers' reasonable stock
    valuation and the company's strong pipeline of new products under
    development. In contrast, Pfizer was hit hard by problems with a
    once-promising drug under development that had to be withdrawn from
    clinical trials because of serious side-effects. In the consumer
    discretionary sector, leading performers included retailer JC Penney,
    diversified publisher McGraw-Hill, and apparel company Liz Claiborne. JC
    Penney exceeded earlier expectations of revenues from its strong
    franchise of department stores. McGraw-Hill benefited from heavy new bond
    issuance which increased business for its Standard & Poor's bond-rating
    business. Meanwhile, Liz Claiborne enjoyed strong demand for its fashion
    products.


    Stock selection was less successful in the telecommunications services and
    utilities areas. In telecommunications services, we owned Sprint and
    Verizon, which did not perform particularly well, while we did not own any
    AT&T, which performed well because of enthusiasm over its merger with Bell
    South. Sprint suffered from a weak marketing campaign and difficulties
    executing its merger with Nextel. In the utilities sector, a significant
    underperformer was


                                                                               5

    Questar, a gas utility that also had major operations in natural gas
    exploration and production. That business was hurt by declining prices for
    natural gas during the six months.


Q:  What is your investment outlook?


A:  We see good potential for a continued supportive environment for equities.
    Stock valuations are not high, by historical standards, while the economy
    continues to grow, although at a moderating pace. Inflation and interest
    rates remain moderate by historical standards, and continued heavy
    mergers-and-acquisition activity provides a base of support for equity
    prices. We see the most significant near-term concerns coming from the
    slumping housing industry and the potential fall-out on sub-prime
    mortgage providers. However, we believe strong employment trends, if they
    persist, should give the market the ability to withstand any pressures
    from the weak housing industry.


    Overall, we remain positive about stocks.

Investing in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies. 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. 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 and sectors.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are
statements of the opinion of Fund management as of the date of this report.
These opinions should not be relied upon for any other purposes. Past
performance is no guarantee of future results, and there is no guarantee that
market forecasts discussed will be realized.

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.

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 net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please 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 Russell 1000[RegTM] Value Index measures the performance of large-cap U.S.
value stocks. Index returns assume reinvestment of dividends and, unlike Fund
returns, do not reflect any fees, expenses or sales charges. You cannot invest
directly in the Index.

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------
As a shareowner in the Fund, you incur two types of costs:

(1)   ongoing costs, including management fees, distribution and/or service
      (12b-1) fees, and other Fund expenses; and

(2)   transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.


Using the Tables

Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.   Divide your account value by $1,000
     Example: an $8,600 account value [divided by] $1,000 = 8.6

2.   Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

 Expenses Paid During Period*                                          $    6.50


*  Expenses are equal to the Fund's annualized expense ratio of 1.25% for Class
   A shares, multiplied by the average account value over the period,
   multiplied by 181/365 (to reflect the one-half year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.


You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS 2/28/07 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Select Research Value Fund (the Fund) is one of three portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund was organized on October 12, 2005, and commenced
operations on December 15, 2005. Prior to December 15, 2005, the Fund had no
operations other than those relating to organizational matters and the initial
capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). To date,
no shares have been offered to the public. The Fund shares outstanding at
February 28, 2007, are owned by PFD. The Fund's investment objective is to seek
long-term capital growth.

Investing in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies. Information regarding the Fund's principal
investment risks is contained in the Fund's prospectus. Please refer to that
document when considering the Fund's investment 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 gain or loss on investments during the
reporting periods. 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 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


                                                                              21


Pioneer Select Research Value Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited) (continued)
- --------------------------------------------------------------------------------

    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. As of February 28, 2007, there were no securities
    fair valued. Temporary cash investments are valued at amortized cost.

    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 Fund becomes aware 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, 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.

    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.

    The tax character of current year distributions paid will be determined at
    the end of the current fiscal year. There were no distributions paid
    during the period ended August 31, 2006.

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



C.  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.


2. Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary
of UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.75% of the Fund's average daily net
assets up to $1 billion and 0.70% of the excess over $1 billion. For the six
months ended February 28, 2007, the management fee was equal to 0.75% of the
Fund's average daily net assets.

Through January 1, 2009, PIM has agreed not to impose all or a portion of its
management fee and to assume other operating expenses


                                                                              23

of the Fund to the extent necessary to limit Class A expenses to 1.25% of the
average daily net assets attributable to Class A shares.

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 February 28, 2007, $12 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.


3. Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (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 $5,082 in transfer agent fees payable to PIMSS
at February 28, 2007.


4. Distribution Plan

The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the
Investment Company Act of 1940. The Fund will pay PFD a service fee of up to
0.25% of the 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. There were no distribution
fees payable to PFD at February 28, 2007.


5. New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than June 29, 2007.

At this time, management is evaluating the implications of FIN 48 and any
impact in the financial statements has not yet been determined.

In addition, 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.

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
- --------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees"), voting
separately, annually approve the Fund's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract: (i) will
enable the Fund to receive quality investment advisory services at a fee deemed
reasonable; and (ii) is in the best interests of the Fund and its shareowners.
In making such determinations, the Independent Trustees relied upon the
assistance of counsel to the Independent Trustees and counsel to the Fund.

Throughout the year, the Independent Trustees regularly met in executive
session, separately from the Interested Trustees of the Fund and any officer of
Pioneer Investment Management, Inc., the Fund's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Interested
Trustees, act on all major matters relating to the Fund, a significant portion
of the activities of the Board of Trustees (including certain of those
described herein) is conducted through committees, the members of which are
comprised exclusively of Independent Trustees. Such committee meetings are
attended by officers of the Fund and/or officers of the Investment Adviser to
the extent requested by the members of the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and also
relied upon their knowledge, resulting from their meetings throughout the year,
of the Investment Adviser, its services and the Fund. Both in meetings
specifically dedicated to renewal of the Management Contract and at other
meetings during the course of the year, the Trustees, including the Independent
Trustees, received materials relating to the Investment Adviser's investment
and management services under the Management Contract. These materials included
information on (i) the investment performance of the Fund, a peer group of
funds as classified by Morningstar, Inc., an independent evaluation service
("Morningstar") and an index considered appropriate by the Independent Trustees
for this purpose, (ii) sales and redemption activity in respect of the Fund,
(iii) the general investment outlook in the markets in which the Fund invests,
(iv) arrangements in respect of the distribution of the Fund's shares, (v) the
procedures employed to determine the value of each of the Fund's assets, (vi)
the Investment Adviser's management of the relationships


26


Pioneer Select Research Value Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

with the Fund's unaffiliated service providers, (vii) the record of compliance
with the Fund's investment policies and restrictions and with the Fund's Code
of Ethics and the structure and responsibilities of the Investment Adviser's
compliance department and (viii) the nature, cost and character of
non-investment management services provided by the Investment Adviser and its
affiliates.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested, and the Investment
Adviser provided, additional information in order to evaluate the quality of
the Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one year period for the Fund and a
peer group of funds selected on the basis of criteria considered appropriate by
the Independent Trustees for this purpose, (2) management and other fees
incurred by a peer group of funds selected on the basis of criteria considered
appropriate by the Independent Trustees for this purpose, (3) the advisory fees
of comparable portfolios of other clients of the Investment Adviser, (4)
expense ratios for the Fund and a peer group of funds selected on the basis of
criteria considered appropriate by the Independent Trustees for this purpose,
(5) the overall organization of the Investment Adviser, (6) the Investment
Adviser's financial results and condition, including its and certain of its
affiliates' profitability in providing services to the Fund, (7) transfer
agency fees and administrative reimbursements paid to the Investment Adviser or
affiliates, (8) investment management staffing, and (9) operating expenses paid
by the Funds to third parties. The Trustees also reviewed information regarding
the potential for each of the Fund and the Investment Adviser to benefit from
further economies of scale in the management of the Fund in light of reasonable
growth expectations for the Fund and certain of the Fund's expenses that are
incurred on a basis other than as a percentage of net assets.

The following summarizes factors considered by the Trustees in connection with
reviewing the information described above and their renewal of the Fund's
Management Contract. The Trustees did not identify any single factor as
all-important or controlling, and the summary does not detail all the matters
that were considered.

A.  Ancillary Benefits to Shareowners. The Trustees considered the benefits to
    shareowners of investing in a Fund that is part of a


                                                                              27

APPROVING THE MANAGEMENT CONTRACT                                  (continued)
- --------------------------------------------------------------------------------

    large number of investment companies offering a variety of investment
    disciplines and providing for a large variety of Fund and shareowner
    services.

B.  Compliance and Investment Performance. The Trustees determined that the
    Investment Adviser had policies and systems reasonably designed to achieve
    compliance with the Fund's investment objective and regulatory
    requirements. The Trustees also reviewed the Fund's absolute investment
    performance based upon total return, as well as the Fund's performance
    relative to the performance of both a peer group and an index considered
    appropriate by the Independent Trustees for this purpose. The Fund's
    performance, based upon total return, was in the first quintile of its
    Morningstar category peer group for the period ended June 30, 2006. (In
    all quintile rankings referred to throughout this discussion first
    quintile is most favorable to the Fund's shareowners. Thus, highest
    relative performance would be first quintile and lowest relative expenses
    also would be first quintile.) The Trustees concluded that the performance
    of the Fund was strong during the short period since its inception.

C.  The Investment Adviser's Personnel and Methods. The Trustees reviewed the
    background of members of the team responsible for the daily management of
    the Fund and the Fund's investment objective and discipline. The
    Independent Trustees also have had discussions with senior management of
    the Investment Adviser responsible for investment operations and the
    senior management of the Investment Adviser's equities group. Among other
    things, the Trustees considered the size, education and experience of the
    Investment Adviser's investment staff and their use of technology and
    emphasis on analytics in view of the risk profile of securities in which
    the Fund invests. The Trustees concluded that the Investment Adviser had
    the quality and depth of personnel and the well-developed methods
    essential to perform its duties under the Management Contract.

D.  Nature and Quality of Other Services. The Trustees considered the nature,
    quality and extent of other services provided to shareowners of the Fund,
    including administrative and shareowner services performed by the
    Investment Adviser under the Management Contract. The Trustees also
    considered the reasonableness of the arrangements for reimbursement of the
    Investment Adviser's


28


Pioneer Select Research Value Fund
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

    out-of-pocket costs and expenses, including overhead, for certain
    administrative services that the Investment Adviser is not required to
    provide under the Management Contract. The Trustees also considered the
    nature and extent of the other services provided by the Investment Adviser
    or its affiliates under other contracts, as well as the Investment
    Adviser's supervision of third party service providers. Based on these
    considerations, the Trustees concluded that the nature, quality and extent
    of such services are satisfactory and reliable and serve the shareowners
    of the Fund well.

E.  Management Fee and Expenses. The Trustees considered the Investment
    Adviser's fee under the Management Contract relative to the management
    fees charged by its Morningstar category peer group. The Fund's management
    fee for the period ended June 30, 2006 was in the second quintile relative
    to the management fees paid by the other funds in that peer group for the
    comparable period. The Trustees also considered the Fund's expense ratio
    for the period ended June 30, 2006 and expense ratios for the comparable
    period of the peer group of funds selected on the basis of criteria
    considered appropriate by the Independent Trustees for this purpose using
    data provided by Strategic Insight Mutual Fund Research and Consulting,
    LLC, an independent third party. The Trustees found the Fund's expense
    ratio for the period ended June 30, 2006 to be in the first quintile,
    according to data for the applicable peer group for the most recent fiscal
    year.

F.  Profitability. The Trustees considered the level of the Investment
    Adviser's profits with respect to the management of the Pioneer Funds,
    including a review of the Investment Adviser's methodology in allocating
    certain of its costs to the management of each Fund, as well as the
    financial results realized by the Investment Adviser in connection with
    the operation of the Fund. They further considered the profits realized by
    the Investment Adviser and its affiliates from non-fund businesses that
    may benefit from or be related to the Fund's business. The Trustees
    considered the Investment Adviser's profit margins in comparison with the
    limited industry data available. The Trustees concluded that the
    Investment Adviser's profits from management of the Pioneer Funds,
    including the financial results derived from the Fund, bear a reasonable
    relationship to the services rendered and are fair for the management of
    the Fund.


                                                                              29

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

G.  Economies of Scale. The Trustees considered the economies of scale with
    respect to the management of the Fund, whether the Fund had appropriately
    benefited from any economies of scale, and whether there was potential for
    realization of any further economies of scale. The Trustees concluded that
    in light of anticipated growth of the Fund, break points in the management
    fee were not necessary at this time. However, the Trustees would evaluate
    the need for break points from time to time.

H.  Other Benefits to the Investment Adviser. The Trustees also considered the
    character and amount of fees paid by the Fund, other than under the
    Management Contract, for services provided by the Investment Adviser and
    affiliates, including fees for services such as shareowner services. The
    Trustees also considered the receipt of sales loads and payments under
    Rule 12b-1 plans in respect of the Pioneer Funds (including the Fund), and
    benefits to the Investment Adviser from the use of "soft" commission
    dollars to pay for research services. The Trustees further considered the
    revenues and profitability of the Investment Adviser's businesses other
    than the fund business, including the Investment Adviser's institutional
    investment advisory business. The Trustees considered the intangible
    benefits that accrue to the Investment Adviser and its affiliates by
    virtue of its relationship with the Fund and the Pioneer Funds as a group.
    The Trustees concluded that all these types of benefits accruing to the
    Investment Adviser were reasonable in the context of the overall
    relationship between the Investment Adviser and the Fund.


Conclusion. In light of the Investment Adviser's overall performance, the
Trustees considered it appropriate to continue to retain the management
services of the Investment Adviser. Based on their review of the overall nature
and quality of services provided by the Investment Adviser and the fees charged
by other funds in the Fund's relevant peer group, and taking into account all
material factors deemed relevant by the Trustees as well as the advice of
independent counsel, the Trustees concluded that the Management Contract with
the Fund, including the fee payable thereunder, was fair and reasonable and
that its renewal was in the best interests of the Fund and its shareholders.
Accordingly, the Trustees voted to approve the continuation of the Management
Contract for another year.

 Dear Shareowner,
- --------------------------------------------------------------------------------
Welcome to Pioneer. We thank you for your investment in Pioneer High Income
Municipal Fund and are pleased to provide you with the Fund's first shareholder
report since its inception on October 16, 2006.

In managing the Pioneer High Income Municipal Fund, we seek what we believe are
the best values in the high-income marketplace. In an interview starting on
page 4 of this report, Fixed-Income Portfolio Manager Timothy Pynchon discusses
the investment strategies used over the abbreviated fiscal period since October
16, 2006.

As the global economy reacted to good and bad news of 2006, overall it managed
to keep chugging along with fairly stable growth. Looking back, the economic
stories included slowing economic growth bringing monetary tightening to an end
in the United States, price action in oil and other commodity markets
threatening to unsettle global growth and inflation, geopolitical uncertainties
and corporate earnings growth surpassing market expectations.

U.S. economic growth slowed gradually over 2006, with full-year growth of GDP
of 3.1%, modestly below 2005 growth, but still strong enough to lower the
unemployment rate to 4.5%. While many observers were concerned that a weakening
housing sector could be a drag on consumer spending, the consumer has shown
resilience, supported by a strong labor market and associated income growth and
by oil and gasoline prices falling from record highs in the second half of
2006. Corporate America has also proved resilient in the face of the slowing
housing sector, with business investment growing at its fastest rate since
2000.

The Federal Reserve stopped increasing interest rates in mid-2006, but has
retained its bias to tighten rates, reflecting upside risks to inflation,
particularly from the tight labor market, and confidence that the economy
remained on solid ground. Consumers welcomed the relief from oil prices that
peaked at mid-year and fell sharply towards year-end. Likewise, in the second
half of 2006, they benefited from the modest easing of core inflation (which
excludes energy and food items), though such core inflation remains above what
is generally considered the central bank's "comfort zone."

While global economic momentum has started to slow, we expect the global
economy to continue growing firmly in 2007, supported by business investment,
rising employment, and lower energy prices. A slowdown in the U.S. growth rate
would be welcome, since rapid growth could increase

the risk of inflationary pressures, which would force the Federal Reserve to
raise interest rates. We expect Europe and Japan to grow similarly, while
emerging market economies are expected to continue their strong growth. In this
scenario, fixed-income assets are expected to produce total returns generally
in line with their current yields, while equities are expected to produce
returns generally in line with earnings growth, which we forecast to be
moderately above bond yields.

Our cautiously optimistic outlook on most regions of the world and asset
classes reinforces the importance of Pioneer Investments' message that
investors should remain diversified, take a long-term view rather than
over-reacting to breaking news, and base investment decisions on economic and
market fundamentals rather than on emotion. Our investment philosophy and
approach continue to be based on the use of fundamental research to identify a
range of opportunities that offer an attractive balance of risk and reward to
help Fund shareowners work toward their long-term goals.

Since the founding of Pioneer Fund, our flagship fund, in 1928, our only
purpose has been to help investors achieve their objectives. Over the months
and years ahead, we will continue to offer you the high caliber of investment
management that our shareowners have enjoyed for more than seven decades.

Respectfully,

/s/ John F. Cogan, Jr.

John F. Cogan, Jr., Chairman
Pioneer Investment Management, Inc.

Pioneer High Income Municipal Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 2/28/07
- --------------------------------------------------------------------------------

During the abbreviated fiscal period from the Fund's inception on October 17,
2006, through February 28, 2007, high-yield municipal bonds were one of the
best performing areas of the fixed-income market. Investors in Pioneer High
Income Municipal Fund not only earned a relatively high level of tax-exempt
income, they also benefited from the capital appreciation that some bonds
provided. In the following interview, portfolio manager Timothy Pynchon
discusses the investment strategies used in building a portfolio of high-yield
municipal securities.


Q:  How did the Fund perform?


A:  Since inception on October 17, 2006 through February 28, 2007, Pioneer High
    Income Municipal Fund's Class A shares produced a 4.05% total return at net
    asset value. The Fund's benchmark, the Lehman Brothers High Yield Municipal
    Bond Index, returned 2.70%, and the average return of the 88 funds in the
    Lipper High Yield Municipal Debt Funds category was 2.01% for the comparable
    (though not identical) period from October 31, 2006 through February 28,

Q:  What were the principal strategies used in managing the Fund during the
    period?


A:  The Fund's objective is to maximize total return through a combination of
    income that is exempt from regular federal income tax and capital
    appreciation by investing in a portfolio of high yield, or below
    investment-grade, municipal securities. In managing the Fund, we have the
    flexibility to invest in bonds that we believe will perform well over the
    long term. We are not tied to index weights or duration, and we rely
    primarily upon Pioneer's expertise in credit research and security selection
    for performance. We believe that proper security selection and the avoidance
    of defaults should consistently lead to solid performance.


    In building the portfolio, we sought undervalued securities with
    relatively high yields that have the potential to appreciate in price. We
    favored sectors that are vital components of the U.S. economy. The sectors
    included public power, transportation, health care, housing, water and
    sewer, among others. We also found opportunity in new areas, such as
    correctional institutions that have been privatized by the federal
    government and charter schools. In addition, we were attracted to the
    securitized sector and invested in a collateralized debt obligation, which
    is backed by a pool of fixed-income securities with different yields and
    varying degrees of credit risk.


    All of the securities in the portfolio are revenue bonds, whose interest
    and principal are paid from the revenues derived from the particular asset
    the bond was issued to finance. At almost 18% of net assets, health care
    bonds accounted for the biggest sector position in the Fund. Health care
    is a large and growing part of the economy and encompasses several areas,
    such as hospitals, nursing homes and continuing care retirement
    communities, among others. It is an area in which bond yields have been
    attractive and supply has been plentiful. Tobacco bonds accounted for
    nearly 10% of net assets, the second largest position in the portfolio.
    These bonds are backed by tobacco companies' payments to states as part of
    the Master Settlement Agreement in which states agreed to drop their
    lawsuits against tobacco companies in return for a series of payments. The
    remainder of the portfolio was in various other revenue bonds. Because
    longer-term yields were higher than shorter-term yields in the municipal
    market


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 2/28/07                            (continued)
- --------------------------------------------------------------------------------

    during the period, we focused on bonds with relatively long maturities. At
    the end of the period, about 43% of the portfolio's bonds had maturities
    of six to eight years, and about 25% had maturities of ten years or more.


Q:  What affected performance over the period?


A:  Over the period, our investments performed well. Some securities are still
    so new to the Fund that it is not yet possible to measure attribution in a
    meaningful way. Two strong performers, however, were Gulf Coast IDA Texas
    Environmental Facilities, a non-rated issue that is using cutting-edge
    technology to produce green energy from methane gas, and St Louis, Missouri
    Convention Center, a Caa-rated security that has had economic difficulties
    but that we believe is a turn-around situation. Both of the credits
    outperformed the market by a wide margin. At period-end, we had no
    detractors from performance.


Q:  What is your outlook?


A:  Against a backdrop of moderating economic growth, relatively low interest
    rates, and contained inflation, we believe the high-yield municipal market
    will continue to generate robust returns. While new bond issuance has
    declined, demand for high-yield bonds has remained strong, as new types of
    investors, such as hedge funds and property-and-casualty insurers, seek the
    higher tax-advantaged yields that below investment-grade municipal bonds can
    provide. We view this supply/demand dynamic as positive for the Fund as it
    has the potential to increase the prices of some of the bonds in the
    portfolio. As we look ahead, we plan to maintain a well diversified
    portfolio from both a sector and geographic perspective. Because the Fund is
    new, the percentages of our holdings are larger than we anticipate as the
    Fund's overall asset levels increase. The percentages will decline as the
    Fund's assets grow and dilute the current holdings. As the Fund grows, we
    expect to add securities and have about 60 to 80 positions in the portfolio.

Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. The Fund may invest in securities of issuers that
are in default or that are in bankruptcy.

A portion of the income may be subject to state, federal, and/or alternative
minimum tax. Capital gains, if any, are subject to a capital gains tax. The
fund is not diversified, which means that it can invest a higher percentage of
its assets in any one issuer than a diversified fund. Being non-diversified may
magnify the fund's losses from adverse events affecting a particular issuer. By
investing primarily in municipal securities, the portfolio is more susceptible
to adverse economic, political or regulatory developments than is a portfolio
that invests more broadly. Investments in the Fund are subject to possible loss
due to financial failure of underlying securities and their inability to meet
their debt obligations.

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. Investments in the
Fund are subject to possible loss due to the financial failure of issuers of
underlying securities and their inability to meet their debt obligations. 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 and sectors.

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

shareowner would pay on Fund distributions or the redemption of Fund shares.

Pioneer High Income Municipal Fund

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.

   multiplied by the average account value over the period, multiplied by
   135/365 (to reflect the partial year period).

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS 2/28/07 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies
Pioneer High Income Municipal Fund (the Fund) is a non-diversified series of
Pioneer Series Trust V, a Delaware statutory trust registered under the
Investment Company Act of 1940 as an open-end management investment company.
The Fund commenced operations on October 17, 2006. The investment objective of
the Fund is to maximize total return through a combination of income that is
exempt from regular federal income tax and capital appreciation.

The Fund offers three classes of shares designated as Class A, Class C, and
Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidations, except that each class of shares can
bear different transfer agent and distribution fees and has exclusive voting
rights with respect to the distribution plans that have been adopted by Class A
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 gain or loss on investments during the
reporting period. Actual results could differ from those estimates.

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 and sectors. More detailed descriptions of the Fund's principal
risks are contained in the Fund's prospectuses. Please refer to those documents
when considering the Fund's risks.

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:


26


Pioneer High Income Municipal Fund
- --------------------------------------------------------------------------------

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


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
    exchange. Securities are valued at prices supplied by independent pricing
    services, which consider such factors as Treasury spreads, yields,
    maturities and ratings. Valuations may be supplemented by dealers and
    other sources, as required. Securities for which there are no other
    readily available market quotations are valued at their fair values as
    determined by, or under the direction of the Board of Trustees. At
    February 28, 2007 there were no securities fair valued. Temporary cash
    investments are valued at amortized cost.

    Discount and premium on debt securities are accreted or amortized,
    respectively daily into interest income on a yield-to-maturity basis with
    a corresponding increase or decrease in the cost basis of the security.
    Interest income is recorded on the accrual basis.

    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, exempt interest income, and net
    realized capital gains, if any, to its shareowners. Therefore, no federal
    tax provision is required.

    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.

    The tax character of current year distributions paid will be determined at
    the end of the current fiscal year.


                                                                              27

NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited)                 (continued)
- --------------------------------------------------------------------------------

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 $239 in underwriting commissions on the sale
    of Class A shares during the period ended February 28, 2007.


D.  Class Allocations

    Distribution fees are calculated based on the average daily net asset
    value attributable to Class A and Class C shares of the Fund, respectively
    (see Note 4). 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 each
    class of shares based on the respective percentage of adjusted net assets
    at the beginning of the day.

    The Fund declares, as daily dividends, substantially all of its net
    investment income. All dividends are paid on a monthly basis. Short-term
    capital gain distributions, if any, may be declared with the daily
    dividends. 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 C, and Class Y shares can bear
    different transfer agent and distribution fees.


2.  Management Agreement

Pioneer Investment Management, Inc., (PIM), a wholly owned indirect subsidiary
of UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets up to $500 million; 0.475% of the next $500 million; and 0.45% of the
excess over $1 billion. For the period ended February 28, 2007, the net
management fee was equivalent to 0.50% of average daily net assets.


28


Pioneer High Income Municipal Fund
- --------------------------------------------------------------------------------

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

PIM has agreed not to impose all or a portion of its management fee and to
assume other operating expenses (excluding taxes, commissions, interest and
extraordinary expenses) of the Fund to the extent necessary to limit expenses
to 0.90% and 1.80% of the average daily net assets attributable to Class A
shares and Class C shares, respectively. The Class A limitation is in effect
through January 1, 2009 and the Class C limitation is in effect through January
1, 2008.

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 February 28, 2007, $5 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.


3.  Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareholder services to the Fund at
negotiated rates. Included in due to affiliates is $522 in transfer agent fees
payable to PIMSS at February 28, 2007.


4.  Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A 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 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 C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to Class C
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 C shares. Included in due to
affiliates is $84 in distribution fees payable to PFD at February 28, 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. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid


                                                                              29


Pioneer High Income Municipal Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 2/28/07  (unaudited)                 (continued)
- --------------------------------------------------------------------------------

to PFD. There is no CDSC for Class Y shares. For the period ended February 28,
2007, no CDSCs 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 period ended February 28, 2007, the Fund's
expenses were not reduced under such arrangements.


6.  New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than August 31, 2007. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In addition, 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.

 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.

of Schedule 14A (17 CFR 240.14a-101), or this Item.


There have been no material changes to the procedures by which the
shareholders may recommend nominees to the registrants board of
directors since the registrant last provided disclosure in response
to the requirements of Item 7(d)(2)(ii)(G) of Schedule 14(A) in
its definitive proxy statement, or this Item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

The registrant's principal executive officer
and principal financial officer have
concluded that the registrant's disclosure
controls and procedures are effective based
on their evaluation of these controls and
procedures as of a date within 90 days of the
filing date of this report.


(b) Disclose whether or not there were significant changes in the registrant's
internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

There were no significant changes in the
registrant's internal control over financial
reporting that occurred during the second
fiscal quarter of the period covered by this
report that have materially affected, or are
reasonably likely to materially affect, the
registrant's internal control over financial
reporting.

The registrant's principal executive officer and principal financial
officer, however, voluntarily are reporting the following information:

In August of 2006 the registrant's investment adviser
enhanced its internal procedures for reporting performance
information required to be included in prospectuses.
Those enhancements involved additional internal controls
over the appropriateness of performance data
generated for this purpose.  Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of
a limited number of registrants where, inadvertently,
performance information not reflecting the deduction of
applicable sales charges was included. Those prospectuses
were revised, and the revised prospectuses were distributed to
shareholders.


ITEM 12. EXHIBITS.

File the exhibits listed below as part of this Form. Letter or number the
exhibits in the sequence indicated.

(a) Any code of ethics, or amendment thereto, that is the subject of the
disclosure required by Item 2, to the extent that the registrant intends to
satisfy the Item 2 requirements through filing of an exhibit.



(b) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2 under the Act
(17 CFR 270.30a-2).

Filed herewith.
