President's Letter

Dear Shareowner,

Stock and bond markets around the globe this year have experienced one of their
most tumultuous periods in history. Investors have witnessed volatility of a
magnitude that many have never before seen. Distance often provides the best
vantage point for perspective. Still, we believe that the benefits of basic
investment principles that have stood the test of time -- even in the midst of
market turmoil -- cannot be underestimated.

First, invest for the long term. The founder of Pioneer Investments, Philip L.
Carret, began his investment career during the 1920's. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme economic slumps can create opportunities for purchase. Indeed, many of
our portfolio managers, who follow the value-conscious investing approach of
our founder, are looking at recent market conditions as an opportunity to buy
companies whose shares we believe have been unjustifiably beaten down by
indiscriminate selling, but that we have identified as having strong prospects
over time. While investors may be facing a sustained market downturn, we
continue to believe that patience, along with staying invested in the market,
are important considerations for long-term investors.

A second principle is to stay diversified across different types of
investments. The global scope of the current market weakness poses challenges
for this basic investment axiom. But the turbulence makes now a good time to
reassess your portfolio and make sure that your investments continue to meet
your needs. We believe you should work closely with your financial advisor to
find the mix of stocks, bonds and money market assets that is best aligned to
your particular risk tolerance and investment objective.

As the investment markets sort through the continuing crisis in the financial
industry, we are staying focused on the fundamentals and risk management. With
more than 80 years of experience behind us, we have learned how to navigate
turbulent markets. At Pioneer Investments, risk management has always been a
critical part of our culture -- not just during periods of extraordinary
volatility. Our investment process is based on fundamental research,
quantitative analysis and active portfolio management. This three-pillared
process, which we apply to each of our portfolios, is supported by an
integrated team approach and is designed to carefully balance risk and reward.
While we

see potential chances for making money in many corners of the market, it takes
research and experience to separate solid investment opportunities from
speculation.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
www.pioneerinvestments.com. Thank you for investing with Pioneer.

Respectfully,

/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 9/30/08

Domestic stock prices generally fell amid growing investor unease about the
spreading effects of problems in credit markets during the six months ended
September 30, 2008. In the following interview, portfolio managers Timothy
Mulrenan and Andrew Acheson discuss the factors that affected the performance
of Pioneer Fundamental Growth Fund during the six-month period ended September
30, 2008.

Q    How did the Fund perform during the six months ended September 30, 2008?

A    Pioneer Fundamental Growth Fund Class A shares returned -8.92% at net asset
     value for the period, while the Fund's benchmark, the Russell 1000 Growth
     Index (the Russell Index), returned -11.23% over the same six-month period.
     The Fund's conservative positioning during the six months helped it
     outperform both the Russell Index and the average return of -12.67% for the
     810 mutual funds in Lipper's Large Cap Growth category.

Q    What were the principal factors that affected the Fund's performance over
     the six months ended September 30, 2008?

A    We are never happy with negative results, but we had anticipated that we
     were entering a very challenging environment because of the credit crisis
     in the financial system. As a result, we positioned the Fund cautiously for
     a difficult market environment, emphasizing investments in corporations
     with stable balance sheets, relatively little debt and histories of
     producing consistent earnings growth over longer periods of time. We tried
     to avoid investing in companies that were very credit-sensitive, especially
     banks and brokers, and we also de-emphasized corporations whose earnings
     were closely linked to movements in the business cycle. We de-emphasized
     the Fund's energy sector allocation, which was the worst-performing market
     sector during the six months ended September 30, as oil and natural gas
     prices started retreating from their all-time highs. Meanwhile, we
     overweighted the Fund in health care, which was the best-performing sector
     in the market. We also attempted to take advantage of weakness in the stock
     market to establish new investments for the Fund in highly profitable
     corporations with durable businesses. For example, we initiated positions
     for the Fund in Google, the leader in Internet search and advertising;
     MasterCard, the credit and debit card company; and Oracle, a major provider
     of enterprise-wide software systems for large organizations. In adding
     these investments to the Fund, we recognized that no corporations were
     immune from the market turmoil. However, we wanted to initiate investments
     for the Fund in companies we believed had superior business


4    Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08


     prospects for the long run. We focused the Fund on higher-quality companies
     led by successful management teams, with superior returns on capital, and
     with the ability to generate healthy cash flows that would allow them to
     invest in their businesses without being dependent on borrowing money in
     the credit markets.

Q    What were some of the investments that helped the Fund outperform its
     benchmark and the Lipper funds average over the six-month period ended
     September 30?

A    Despite the turmoil in the overall market, several health care stocks held
     up well, including Thoratec, Medtronic and Thermo Fisher Scientific.
     Thoratec has established itself as a leading producer of artificial heart
     pumps for cardiac patients. Its share price rose by more than 80% during
     the period following the Food and Drug Administration's (FDA) approval of a
     new product for patients with late-stage heart disease. The Fund had a
     small position in Thoratec, but a larger position in Medtronic, whose
     valuation stabilized during the period in an otherwise down market, as the
     company continued to deliver good earnings results on sales of its medical
     devices. The company, which is under new management, also embarked on a
     share repurchase program and increased its stock dividend, pleasing company
     shareholders. Meanwhile, Thermo Fisher Scientific, a producer of scientific
     equipment, benefited from strong cash flow generated by its diversified
     customer base of medical and scientific research laboratories. Outside the
     health care sector, one notable contributor to the Fund's performance
     during the period was Ross Stores. This discount retailer of branded
     apparel showed solid earnings results as the weakening economy encouraged
     cost-conscious consumers to look for lower prices. Slowing sales at
     department stores and major retailers, from which Ross Stores buys much of
     its inventory, also improved the company's position in price negotiations
     with those larger stores.

Q    What were some of the investments that detracted from the Fund's
     performance over the six-month period ended September 30?

A    Several holdings produced disappointing results over the six-month period.
     International Game Technology, the largest producer of gaming machines for
     casinos, fell victim to declines in business at many of the major casinos,
     as well as the difficulties that casinos experienced in getting credit
     financing for new equipment. We have retained the Fund's position in the
     company, however, because we think it has the opportunity to rebound in
     2009, when the gambling industry moves to a new technology platform that
     will give casinos the ability to change the games being played at specific
     locations or terminals. Apparel retailer Abercrombie & Fitch also detracted
     from the Fund's results when its profits were affected by slowing sales at
     the same time the company was making new investments for future growth. The
     Fund's investment in Intercontinental Exchange, an electronic trading


              Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08    5


     platform for financial products, also held back results. The company's
     share price declined on expectations that weaker capital markets,
     especially in commodities, would lead to lower trading volumes. We believe
     that Intercontinental Exchange's longer-term outlook remains good,
     especially as it introduces new products to augment its traditional trading
     platforms. Also detracting from the Fund's return over the six-month period
     was a position in Corning, a global leader in producing glass panels for
     flat-panel television sets. An oversupply of inventory for flat-panel
     displays decreased the company's short-term results. However, we continue
     to believe that Corning is well positioned to benefit from the longer-term
     growth in sales as flat panel television sets become more affordable.

Q    What is your investment outlook?

A    We expect that global economic growth will continue to be weak in the
     months ahead as the result of the fallout from the credit crisis. While the
     policies of the U.S. Treasury and the Federal Reserve Board, often acting
     in concert with other governments, may cushion the effects of this crisis,
     we do not anticipate a meaningful economic recovery until 2009. The key to
     any recovery will be a stabilization of housing values. A reduction in the
     inventories of unsold homes and a moderation in the rate of decline in
     housing prices will likely be catalysts to a recovery.

     While we foresee more volatility in equity prices in the near term, we
     think we already are seeing some very attractive values appear in the
     stocks of fundamentally sound companies. In this environment, we plan to
     continue to upgrade the Fund's overall portfolio with stocks of reasonably
     priced, long-term growth companies with superior earnings potential. If the
     credit crisis is resolved soon, the market could begin to rebound. Some
     very attractive companies currently are selling at extraordinarily low
     stock prices in relation to their profitability. However, if the credit
     crisis is not resolved soon, a further deterioration in stock values is
     possible.

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 8/1/2010 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

             Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08    11


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 2.15% for Class A, Class B and Class C shares, respectively, multiplied
     by the average account value over the period, multiplied by 183/366 (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.

     period, reinvestment of all distributions, the complete redemption of the
     investment at net asset value at the end of each period, and no sales
     charges. Total return would be reduced if sales charges were taken into
     account.
**   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 expenses ratio to average net assets
     would have been 5.31%. As a result of the expenses limitation arrangement
     (see footnote 2), there would be no effect on the per share operating
     performance, total return and the net expenses and net investment loss
     ratios to average net assets.

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's
investment objective is to seek long-term capital growth.

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 proceeds, 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 year. 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. The Fund's prospectuses (unaudited) contain information
regarding the Fund's principal risks. Please refer to those documents when
considering the Fund's principal 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:

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.


             Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08    27


     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, 2008, there were no
     securities fair valued. Temporary cash investments are valued at cost which
     approximates market value.

     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
     date in the 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. Tax
     years prior to 2004 are closed (not subject to examination by tax
     authorities) due to the expiration of statute of limitations; all other tax
     years are open.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as from or in excess of net
     investment income or as from net realized gain on investment transactions,
     or as from paid-in capital, depending on the type of book/tax differences
     that may exist.

     The tax character of current year distributions will be determined at the
     end of the Fund's fiscal year. The tax character of distributions paid
     during the year ended March 31, 2008 was as follows:



                                                                          2008

        Total                                                           $91,576
================================================================================


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

C.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredit S.p.A.
     (UniCredit), earned $631 in underwriting commissions on the sale of Class A
     shares during the six months ended September 30, 2008.

D.   Security Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Fund's custodian acting as the
     lending agent. When entering into a loan, the Fund receives collateral,
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Fund also continues to receive interest or
     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 which is required to be at least 102%, at all times, of the fair
     value of the securities loaned. The amount of collateral is required to be
     adjusted daily to reflect any price fluctuation in the value of the loaned
     securities. The Fund has the right under the lending agreement to recover
     the securities from the borrower on demand. The fund invests cash
     collateral in cash equivalent investments. Securities lending collateral is
     managed by Credit Suisse.

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


             Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08    29


     determining that the value of the collateral remains at least equal to the
     repurchase price.

F.   Class Allocations

     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on the respective percentage of adjusted net assets at the beginning
     of the day.

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B and Class C shares of the Fund,
     respectively (see Note 4). Shareowners of each class participate in all
     expenses and fees paid to the transfer agent, Pioneer Investment Management
     Shareholder Services, Inc. (PIMSS), for its services, which are allocated
     based on the number of accounts in each class and the ratable allocation of
     related out-of-pocket expense (see Note 3). Distributions to shareowners
     are recorded as of the ex-dividend date. Distributions paid by the Fund
     with respect to each class of shares are calculated in the same manner, 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 expense
     rates.

2.   Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.75% 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 are in effect through
August 1, 2010 for Class A shares and through August 1, 2009 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. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $2 in management fees,
administrative costs and certain other services payable to PIM at September 30,
2008.

3.   Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $3,155 in transfer agent fees payable to PIMSS at September 30,
2008.

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 Plan, the Fund pays PFD 0.25% of the Fund's average daily
net assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average
daily net assets attributable to Class B and Class C shares. The fee for Class
B and Class C shares 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.
Prior to February 1, 2008, PFD was reimbursed under the Plan of Distribution
for distribution expenses in an amount of up to 0.25% of the average daily net
assets attributable to Class A shares. Included in "Due to affiliates"
reflected on the Statement of Assets and Liabilities is $60 in distribution
fees payable to PFD at September 30, 2008.

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%, based on the lower
of cost or market value of shares being redeemed. Proceeds from the CDSCs are
paid to PFD. For the six months ended September 30, 2008, no CDSCs 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, 2008, the Fund's
expenses were reduced by $86 under such arrangements.

6.   New Pronouncement

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities ("SFAS 161"), was issued
and is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Fund's financial statement disclosures.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
The Trustees of the Fund, as required by law, determine annually whether to
continue the investment advisory agreement for the Fund. In connection with
their most recent consideration of the investment advisory agreement for the
Fund, the Trustees received and reviewed a substantial amount of information
provided by PIM in response to requests of the independent Trustees and their
independent legal counsel. The independent Trustees met on a number of
occasions with PIM and also separately with their independent legal counsel to
evaluate and discuss the information provided to them by PIM. At a meeting held
on November 13, 2007, based on their evaluation of the information provided by
PIM, the Trustees, including the independent Trustees voting separately,
unanimously approved the continuation of the investment advisory agreement for
another year.

At a meeting held on January 8, 2008, the Trustees considered whether an
amended and restated investment advisory agreement for the Fund should be
approved for an initial period ending December 31, 2009. The management fee to
be paid by the Fund to PIM under the amended and restated investment advisory
agreement is the same as the management fee provided in the previously approved
investment advisory agreement. Based on their evaluation of the information
provided by PIM, including the information provided by PIM in connection with
the Trustees' most recent approval of the continuation of the previous
investment advisory agreement, the Trustees, including the independent Trustees
voting separately, unanimously approved the amended and restated investment
advisory agreement. Shareholders of the Fund approved the amended and restated
investment advisory agreement at a meeting held on May 13, 2008.

In considering the amended and restated investment advisory agreement, the
Trustees considered various factors that they determined were relevant,
including the factors described below. The Trustees did not identify any single
factor as the controlling factor in determining to approve the amended and
restated investment advisory agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services that
were provided by PIM to the Fund under the previous investment advisory
agreement, and that would continue to be provided by PIM to the Fund under the
amended and restated investment advisory agreement, taking into account the
investment objective and strategy of the Fund and the information related to


34    Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08


the Fund provided to the Trustees at each quarterly meeting. The Trustees
reviewed the terms of the amended and restated investment advisory agreement.
The Trustees also reviewed PIM's investment approach for the Fund and its
research process. The Trustees considered the resources of PIM and the
personnel of PIM who provide investment management services to the Fund. They
also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provided under
the previous investment advisory agreement and that PIM would continue to
provide to the Fund under the amended and restated investment advisory
agreement and that, as administrator, PIM is responsible for the administration
of the Fund's business and other affairs. It was noted that PIM supervises and
monitors the performance of the Fund's service providers and provides the Fund
with personnel (including officers) as are necessary for the Fund's operations.
The Trustees considered the fees paid to PIM for the provision of such
services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that PIM would continue to provide to the Fund under
the amended and restated investment advisory agreement, were satisfactory and
consistent with the terms of the amended and restated investment advisory
agreement.

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
average performance of its peer group of funds as classified by Morningstar,
Inc. (Morningstar), an independent provider of investment company data, and
with the performance of the Fund's benchmark index. The Trustees considered
that the Fund's annualized total return was in the second quintile of its
Morningstar category for the one and three year periods ended June 30, 2007.
(In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Fund's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees concluded that the investment performance of the
Fund was satisfactory.

Management Fee and Expenses
The Trustees considered that the management fee to be paid by the Fund to PIM
under the amended and restated investment advisory agreement would be the same
as the management fee to be paid by the Fund under the previously approved
investment advisory agreement. The Trustees considered information on the fees
and expenses of the Fund in comparison to the management fees of its peer group
of funds as classified by Morningstar and the expense ratios of a peer group of
funds selected on the basis of criteria determined by the independent Trustees
for this purpose using data provided by Strategic


             Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08    35


Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an
independent third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2007 was in the third quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2007 was in the second quintile relative to its
Strategic Insight peer group. It was noted that PIM did not currently manage
any accounts with an investment objective and strategies that were similar to
the Fund.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of services provided, taking
into account the fees charged by other advisers for managing comparable mutual
funds with similar strategies. The Trustees also concluded that the Fund's
expense ratio was reasonable, taking into account the size of the Fund, the
quality of services provided by PIM, the investment performance of the Fund and
the contractual expense limitation agreed to by PIM with respect to the Fund.

Profitability
The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Fund in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Fund. The Trustees concluded that PIM's
profitability with respect to the management of the Fund was not unreasonable.

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 considered that, although the Fund pays a management fee at a
fixed rate as a percentage of the Fund's net assets, without any breakpoints,
the management fee rate paid by the Fund for the twelve months ended June 30,
2007 was in the third quintile relative to the management fees paid by other
funds in its peer group Morningstar category for the comparable period and


36    Pioneer Fundamental Growth Fund | Semiannual Report | 9/30/08


that PIM is subsidizing the Fund because it has not reached adequate scale. The
Trustees also considered the relatively small size of the Fund compared to its
peer group Morningstar category. The Trustees concluded that, at current and
reasonably foreseeable asset levels, breakpoints in the management fee were not
currently necessary.

Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered that affiliates of PIM serve as the Fund's
transfer agent and distributor. The Trustees considered the receipt by PIM and
its affiliates of sales loads and payments under Rule 12b-1 plans in respect of
the Fund and the other Pioneer funds and the benefits to PIM and its affiliates
from the use of "soft" commission dollars generated by the Fund to pay for
research and brokerage services. The Trustees further considered the intangible
benefits to PIM by virtue of its relationship with the Fund and the other
Pioneer funds. The Trustees concluded that the receipt of these benefits was
reasonable in the context of the overall relationship between PIM and the Fund.

Conclusion
After consideration of the factors described above as well as other factors,
the Trustees, including all of the independent Trustees, concluded that the
terms of the amended and restated investment advisory agreement between PIM and
the Fund, including the fees payable thereunder, were fair and reasonable and
voted to approve the amended and restated investment advisory agreement for the
Fund.

 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.

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
                 typically well-defined and

                 professional standards (AICPA,
