Dear Shareowner,
- --------------------------------------------------------------------------------
Mature and emerging market economies around the world showed moderate
improvement after a flat second quarter. The U.S. saw some resurgence of
growth, which we expect to continue through the fourth quarter of 2006 and into
2007, although this growth may be slow with housing sector measures down in
recent months. While inflation pressures have risen slightly in recent months,
we believe the United States may now be at the end of the Fed's monetary
tightening cycle. Mature economies, led by Japan, remain firm, as do European
economic prospects, with strong GDP data reflecting the broad-based strength
seen in crucial indicators.

U.S. economic growth was back on track after lackluster market results prior to
Labor Day. Consumer spending rose with receding gas prices, just in time for
the back-to-school season, which retailers now consider the second most
lucrative period after the Christmas season. U.S. economic growth is in line
with our projections; we anticipate U.S. GDP finishing with a level of around
3.0% for 2006.

In our view, the pace of corporate earnings growth should slow amid pressure
from high raw materials costs and moderating economic growth. However, modest
U.S. dollar depreciation and improving growth overseas should offer some
support to U.S. earnings.

The European economy continues to improve and appears to be at its healthiest
in six years, with business confidence showing improvement across sectors and
consumers becoming more optimistic. While business sentiment indicators have
had a tendency to over-estimate growth in recent years, their broad-based
improvement across countries since 2005 is a clear sign that European economic
growth should continue through 2006.

The positive long-term drivers of emerging markets remain in place: improving
domestic growth and inflation stability; structural reform; debt sustainability
and favorable demographics. Together, the emerging markets' current account
surplus is at record highs while external debt as a percentage of GDP is at its
lowest since 1991.

In summary, we think that despite the existence of some inflation pressures
seen by the Federal Reserve and its counterparts in developed economies, it
seems as if interest rates will remain mostly unchanged. U.S. economic growth
is expected to remain positive, as

it should among the developed nations for the remainder of 2006. Any further
geopolitical issues and rising energy prices could lead to deceleration, but
not a derailment from the current healthy pace of economic growth, as
investment is expected to remain robust, benefiting from sustained internal and
international demand worldwide.

Our cautiously optimistic outlook reinforces the importance of Pioneer's
message that investors should remain diversified, take a long-term view, 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.

Respectfully,

/s/ Osbert M. Hood

PORTFOLIO MANAGEMENT DISCUSSION 9/30/06
- --------------------------------------------------------------------------------

Investors in the domestic equity market encountered two very different
environments during the six months ended September 30, 2006. For most of the
spring of the year, stocks slumped amid concerns about the effects of rising
interest rates and dramatically higher energy prices. That backdrop changed
during the summer, however, when the market began climbing as energy prices
started to recede and the Federal Reserve Board paused after two years of
repeated hikes in short-term interest rates. In the following interview,
Christopher M. Galizio and Stephen A. Balter, co-managers of Pioneer
Fundamental Growth Fund, discuss the factors that affected Fund performance
during the six months.

Q:  How did the Fund perform?

A:  The Fund had modest, positive results during a period in which growth
    stocks, which we emphasize, trailed value stocks. Pioneer Fundamental
    Growth Fund's Class A shares produced a total return of 0.09% at net
    asset value for the six months ended September, 30, 2006, compared to the
    -0.12% return of the benchmark Russell 1000 Growth Index. During the same
    period, the average return of the 741 funds in Lipper's Large Cap Growth
    category was -2.59%.

    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 influencing performance?

A:  Early in the period, we faced a particularly challenging environment as
    concerns about higher oil prices and rising interest rates held back the
    stock market, even in the face of very strong earnings results from U.S.
    corporations. It was not until July that the market trend began reversing
    as energy prices started easing and investors anticipated that the
    Federal Reserve Board was near the end of its cycle of interest-rate
    hikes. The persistent growth in corporate earnings increased confidence,
    especially after the

    Federal Reserve decided in August to pause and, at least temporarily, not
    raise short-term interest rates any further. Stocks advanced, staging a
    strong rally in August and September. Returns were not spread evenly
    throughout the market, and the large-cap growth stocks that we emphasize
    continued to lag the performance of large-cap value stocks.

    Throughout the six months, we were overweight information technology and
    health care stocks, where we saw attractive opportunities. We believed -
    and continue to believe - that after a five-year cycle in which cyclical
    stocks, including industrials, provided the performance leadership in the
    market, stocks in other sectors are beginning to offer better values and
    superior cash flow rates.

Q:  What types of investments had the greatest impact on the Fund's results for
    the six months?

A:  Our technology positions did very well, outperforming the technology
    sector's results within the benchmark Russell 1000 Growth Index. One top
    performer was Cisco Systems, where we maintained a large position. This
    major producer of networking equipment was a primary beneficiary of the
    increasing needs of corporations for more bandwidth to move increasingly
    complex files, including radio and television transmissions. Another
    noteworthy tech holding was Apple Computer, which expanded its iPod
    products even as it gained share in the personal computer market with its
    new Macintosh computers that can shift seamlessly from an Apple to a
    Windows environment. A third technology investment that was a major
    contributor to performance was Motorola, which gained market share in the
    global wireless handset market even as it was able to gain better profit
    margins from its sales.

    In health care, biotechnology corporation Gilead Sciences performed very
    well, benefiting from its leadership role in developing therapies for
    treating AIDS as well as from an increasing royalty stream from rising
    sales of Tamiflu, the primary vaccine being produced to fight a possible
    Avian flu epidemic. AstraZeneca, a major global pharmaceutical company
    based in the United Kingdom, also performed well as it improved operating
    earnings margins, helping lift its relatively inexpensive share price.

                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 9/30/06                            (continued)
- --------------------------------------------------------------------------------

    Within the consumer discretionary sector, two retailing companies were
    strong performers. Abercrombie & Fitch showed an ability to introduce new
    store formats and retailing concepts, increasing its revenue growth
    potential. At the same time, TJX, parent company of T.J. Maxx and other
    retail chains, reinvigorated its sales and improved profitability after
    bringing back its former chief executive officer.

    Several other investments, however, had disappointing results during the
    six months. Boston Scientific, which produces devices used in cardiac
    treatments, suffered from slowing sales of its cardiac rhythm management
    system, while investors grew more concerned about possible clotting issues
    associated with drug-coated stents. Dell Computer's share price declined
    as the company encountered tougher competition, including from
    Hewlett-Packard and Lenovo, the Chinese company that acquired IBM's
    personal computer business. The difficult competitive environment forced
    Dell to cut prices, reducing its profit margins. Finally, Home Depot
    suffered as investors grew worried about the effects that the slump in the
    housing market might have on home improvement activity. Despite these
    results, we view Boston Scientific, Dell and Home Depot as good long-term
    investments that are particularly attractive because of their low stock
    prices. We retained our positions in all three companies as of the date of
    this shareholder report.

Q:  What is your investment outlook?

A:  We continued to see attractive values in our analysis of growth stocks,
    especially in information technology and health care. We have also found
    interesting opportunities among consumer retailers, which should benefit
    as lower energy prices put less pressure on consumers. We expect to
    continue to underweight cyclical stocks, including industrials, materials
    and energy companies. We think their relatively high stock valuations
    make them more vulnerable if growth rates decelerate.

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.

   reflect deduction of maximum 5.75% sales charge. All results are historical
   and assume the reinvestment of dividends and capital gains. Other share
   classes are available for which performance and expenses will differ.

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

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

   The Russell 1000 Growth Index measures the performance of large-cap U.S.
   growth stocks. Index returns assume reinvestment of dividends and, unlike

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.

Based on actual returns from April 1, 2006 through September 30, 2006.

Expenses Paid During Period*      $    6.27      $   10.76      $   10.76


*   Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%
    and 2.15% for Class A, Class B and Class C shares, respectively, multiplied
    by the average account value over the period, multiplied by 183/365 (to
    reflect the one-half 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.

    investment at net asset value at the end of the period.
**  Annualized.
*** In the absence of the negative registration fees in the statement of
    operations, which relates to a change in estimate for registration fees in
    the period ended March 2003, the gross expense ratio to average net assets
    would have been 5.31%. As a result of the expense limitation arrangement
    (see footnote 2), there would be no effect on the per share operating
    performance, total return and the net expense and net investment loss ratios
    to average net assets.

NOTES TO FINANCIAL STATEMENTS 9/30/06 (unaudited)

1. Organization and Significant Accounting Policies
Pioneer Fundamental Growth Fund (the Fund), formerly Pioneer Large Cap Growth
Fund, is 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 March 12, 2002, and commenced operations on August 22, 2002. Prior
to August 22, 2002, 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 shares, including Class A shares,
were first publicly offered on December 15, 2005. Prior to December 15, 2005
all Fund shares outstanding were owned by PFD. The Fund's investment objective
is to seek 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. The Fund's prospectus contains information regarding
the Fund's principal risks. 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.
Shares of Class A, Class B and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class
A, Class B and Class C shareowners, respectively.

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 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 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. As
    of September 30, 2006, 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. Dividends and interest are reported net of unrecoverable foreign
    taxes withheld at the applicable country rates.

    Gains and losses on sales of investments are calculated on the identified
    cost method for both financial reporting and federal income tax purposes.

B.  Federal Income Taxes

    It is the Fund's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to
    distribute all of its taxable income and net realized capital gains, if
    any, to its shareowners. Therefore, no federal income tax provision is
    required.

    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

                                                                              29

    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. The tax character of distributions
    paid during the year ended March 31, 2006 was as follows:

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

C.  Fund Shares

    The Fund records sales and repurchases of its shares as of trade date.
    PFD, the principal underwriter for the Fund and a wholly owned indirect
    subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), earned $93
    in underwriting commissions on the sale of Class A shares during the six
    months ended September 30, 2006.

D.  Security Lending

    The Fund lends securities in the 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 fair value 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.

E.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value
    of the underlying securities (collateral), including accrued interest
    received from counterparties, is required to be at least equal to or in
    excess of the value of the repurchase agreement at the time of purchase.
    The collateral for all repurchase agreements is held in safekeeping in the
    customer-only account of the Fund's custodian, or subcustodians. The
    Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is
    responsible for determining that the value of the collateral remains at
    least equal to the repurchase price.

F.  Class Allocations

    Distribution fees are calculated based on the average daily net asset
    value attributable to Class A, Class B and Class C shares of the Fund,
    respectively (see Note 4). Shareowners of each class share all expenses
    and fees paid to the transfer agent, Pioneer Investment Management
    Shareholder Services, Inc. (PIMSS), for its services, which are allocated
    based on the number of accounts in each class and the ratable allocation
    of related out-of-pocket expense (see Note 3). Income, common expenses and
    realized and unrealized gains and losses are calculated at the Fund level
    and

                                                                              31


Pioneer Fundamental Growth Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 9/30/06 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

    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, and in the same amount,
    except that Class A, Class B and Class C shares can bear different
    transfer agent and distribution fees.

2.  Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. Management fees are calculated daily at the annual rate of
0.75% of the Fund's average daily net assets.

PIM has agreed not to impose its management fee and to assume other operating
expenses of the Fund to the extent necessary to limit expenses to 1.25%, 2.15%
and 2.15% of the average daily net assets attributable to Class A, Class B and
Class C shares, respectively. These expense limitations became effective
December 15, 2005 and are in effect through August 1, 2008 for Class A shares
and through August 1, 2007 for Class B and Class C shares. Prior to December
15, 2005, Pioneer had voluntarily agreed not to charge all or a portion of its
management fee and, if necessary, to limit other ordinary operating expenses to
the extent required to reduce Class A expenses to 1.30% of the Fund's 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 September 30, 2006, $6,249 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 $9,048 in transfer agent fees payable to PIMSS
at September 30, 2006.

4. Distribution Plan

The Fund adopted a Plan of Distribution with respect to Class A, Class B and
Class C shares 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 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 $44 in distribution fees
payable to PFD at September 30, 2006.

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 subscribed on or after December 15, 2005 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%. Proceeds from the CDSCs are paid to PFD. For the six months
ended September 30, 2006, CDSCs in the amount of $25 were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended September 30, 2006, 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

                                                                              33


Pioneer Fundamental Growth Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 9/30/06 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

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 will
"more-likely-than-not" be sustained by the applicable tax authority. Tax
positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the reporting period. 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 the effective date. 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.
