rates once again in June in an effort to
inject further stimulus into the
economy. And the weak U.S. dollar helps
exporters and multinational companies
operating in countries with stronger
currencies. One possible lesson to be
learned from the market's decline and
recovery is the importance of staying
invested. Those who stayed with their
commitments participated in the recent
rally, while those who remained on the
sidelines had to play catch-up. If the
protracted slump caused your investment
discipline to slip, this may be an ideal
time to contact your financial advisor
for guid ance on resuming your
investment program.

Our style focuses on companies, not on forecasts

There are always risks, of course, and the direction of the economy is something
of a puzzle at the moment. If it continues to struggle for very long, investors
may once again seek shelter in short-term commitments. However, Pioneer's
portfolio managers and analysts do not base investment decisions on economic
assumptions. Instead, as it has since our founding in 1928, our value-focused
investment style requires complete understanding of a company and its potential.
That means intensive analysis of financial reports, visits to companies and
detailed discussions with corporate managers. When we discover potential that
appears to exceed the market's valuation, that company becomes a candidate for
investment. Our research efforts are aided in no small measure by the global
resources of our parent organization, UniCredito Italiano S.p.A.

Like everyone at Pioneer, I appreciate your continued confidence in our products
and services.

Respectfully,

/s/ Osbert M. Hood

PORTFOLIO MANAGEMENT DISCUSSION 6/30/03
- --------------------------------------------------------------------------------

The quick resolution of the major military campaign in Iraq in March sparked a
stock market rally led by growth stocks, which continued through the end of
June. Equities that had been driven down the furthest in the slump of the
previous three years, including technology and telecommunications issues,
tended to be among the performance leaders in the market revival. In the
following interview, Eric Weigel discusses the factors that influenced the
performance of Pioneer Growth Shares during the six-month period ended June 30,
2003. Mr. Weigel is the day-to-day manager of the Fund's management team.

Q: How did the Fund perform during the first half of 2003?

A: Pioneer Growth Shares performed very well. For the six-month period ended
   June 30, 2003, the Fund's Class A shares had a total return of 13.92%. During
   the same period, the Fund's Class B shares returned 13.52%, while Class C
   shares had a return of 13.40%. All returns are at net asset value. For the
   same period, the Standard & Poor's 500 Index, a benchmark for large-company
   stocks, returned 11.76%, while the Russell 1000 Growth Index had a return of
   13.09%.

Q: What factors influenced the Fund's performance?

A: Our stock selection was excellent, helping the Fund surpass its benchmarks
   even though we deemphasized some of the best-performing sectors relative to
   the Russell 1000 Growth Index.

   We had entered 2003 with a moderately aggressive outlook, emphasizing
   companies that had clearly shown their ability to improve their earnings and
   that had reasonable stock valuations. However, more speculative stocks tended
   to be the performance leaders in the rally that began in March and continued
   through June 30.

   Within the portfolio, our investments in the health care industry, which we
   overweighted relative to the Russell 1000 Growth Index, were major
   contributors to the Fund's performance during the period. Our consumer
   staples holdings also helped overcome our deemphasis of more aggressive
   technology and consumer discretionary stocks, which we believed offered more
   risk than growth potential in the near term.

Q: What were some of the investments that contributed to performance?

A: Health care led the way. Specialty pharmaceutical and generic drug
   manufacturers did well both because of growing sales and because of improving
   prospects in the generic part of the industry, which should benefit from
   President Bush's health care plan. Takeover activity and a more favorable
   regulatory environment also helped biotech stocks post strong results. The
   Fund's performance leaders included Biovail, a specialty pharmaceutical and
   generic manufacturer, and Mylan Labs, a generic company. Scios, a small
   pharmaceutical company, was acquired during the period by Johnson & Johnson
   at a healthy premium to its stock price. Amgen, a leading biotech firm, also
   contributed to performance.

   In the consumer staples group, Estee Lauder was a very strong performer,
   while PepsiCo also helped. Estee Lauder's stock staged a particularly strong
   turnaround from a low valuation. Sales at airport outlets account for 30% of
   the cosmetics company's revenues. As sales increased at the airports and
   other retail locations, the stock performed very well.

Q: What investment decisions detracted from performance?

A: Our decision to deemphasize aggressive technology stocks did not help. While
   we did have representation in the technology industry, we tended to own
   larger, less risky companies. Many of our technology holdings also rose in
   the rally, but they still trailed some of the more speculative performance
   leaders during the period. For example IBM and Nokia, two major positions,
   gained 7% and 8% respectively during the six months but still lagged far
   beyond technology averages. Cadence Design System, another position, rose by
   just 2%. One large holding that performed very well was Intel, which gained
   33%. However, Microsoft, one of the Fund's largest holdings on June 30, 2003,
   at about 7% of assets, actually fell by one-half of one percentage point.

Q: What is your investment outlook?

A: We are cautious. While we still think stocks represent good value in relation
   to bonds, we think stock market prices reflect overly optimistic expectations
   for corporate earnings growth. We believe earnings may rise for the remainder
   of 2003, but they may fall short of market expectations.


                                                                               9

PORTFOLIO MANAGEMENT DISCUSSION 6/30/03                              (continued)
- --------------------------------------------------------------------------------

   We remain slightly underweighted in technology and overweighted in health
   care, which we believe offers more stable and predictable earnings growth
   rates. We will continue to take advantage of major market day-to-day moves in
   stock prices to reduce our positions in higher priced stocks and invest in
   equities with more reasonable valuations.

   We intend to continue to keep the Fund less aggressively positioned, with an
   emphasis on lower risk stocks.

   The preceding information is the opinion of Fund management. Past performance
   is no guarantee of future results, and there is no guarantee that market
   forecasts discussed will be realized.

NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Growth Shares (the Fund) is a Delaware business trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek
appreciation of capital.

The Fund offers five classes of shares - Class A, Class B, Class C, Class R and
Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund and has equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class
A, Class B, Class C and Class R shareowners, respectively. There is no
distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with
accounting principles generally accepted in the United States of America, 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 revenues and expenses during the
reporting periods. Actual results could differ from those estimates. The
following is a summary of significant accounting policies consistently followed
by the Fund, which are in conformity with those generally accepted in the
investment company industry:

A. Security Valuation

    Security transactions are recorded as of trade date. The net asset value
    is computed once daily, on each day the New York Stock Exchange 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 direction of,
    the Board of Trustees. 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

26


Pioneer Growth Shares

    as the Fund is informed 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. Temporary cash investments are
    valued at amortized cost.

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

B. Futures Contracts

    The Fund may enter into futures transactions to hedge against changes in
    interest rates, securities prices, and currency rates or to seek to
    increase total return. Upon entering into a futures contract, the Fund is
    required to deposit with a broker an amount of cash or securities equal to
    the minimum "initial margin" requirements of the associated futures
    exchange. Subsequent payments for futures contracts ("variation margin")
    are paid or received by the Fund, depending on the daily fluctuation in
    the value of the contracts, and are recorded by the Fund as unrealized
    gains or losses. When the contract is closed, the Fund realizes a gain or
    loss equal to the difference between the opening and closing value of the
    contract. The use of futures contracts involves, to varying degrees,
    elements of market risk which may exceed the amounts recognized by the
    Fund. Change in value of the contracts may not directly correlate to the
    change in value of the underlying securities. These risks may decrease the
    effectiveness of the Fund's hedging strategies and potentially result in a
    loss.

     At June 30, 2003 open futures contracts were as follows:

                    Contracts      Settlement      Market       Unrealized
     Type         Long/(Short)        Month         Value         (Loss)

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


C. 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.


                                                                              27


Pioneer Growth Shares
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/03 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

    The characterization of distributions to shareowners for financial
    reporting purposes is determined in accordance with federal income tax
    rules. Therefore, the source 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 year ended December 31, 2002.

    The following shows components of distributable earnings on a federal
    income tax basis at December 31, 2002. These amounts do not include the
    capital loss carryforward.



- -----------------------------------------------------------------------------
                                                                 2002
- -----------------------------------------------------------------------------
                                                         
  Undistributed ordinary income                             $           -
  Undistributed long-term gain                                          -
  Unrealized depreciation                                    (192,738,049)
                                                            -------------
  Total                                                     $(192,738,049)
- -----------------------------------------------------------------------------


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

D. 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 $76,017 in underwriting commissions on the
    sale of Fund shares during the six months ended June 30, 2003.

E. Class Allocations

    Distribution fees are calculated based on the average daily net asset
    value attributable to Class A, Class B, Class C and Class R shares of the
    Fund, respectively. 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


28


Pioneer Growth Shares
- --------------------------------------------------------------------------------

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

    class and the ratable allocation of related out-of-pocket expenses (see
    Note 3). Income, common expenses and realized and unrealized gains and
    losses are calculated at the Fund level and allocated daily to all classes
    of shares based on their respective percentage of adjusted net assets at
    the beginning of the day.

    Distributions to shareowners are recorded as of the ex-dividend date.
    Distributions paid by the Fund with respect to each class of shares are
    calculated in the same manner, at the same time, and in the same amount,
    except that Class A, Class B, Class C, Class R and Class Y shares can bear
    different transfer agent and distribution fees.

F. 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
    dividends on the loaned securities, and unrealized gain or loss in the
    fair value of the securities loaned 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 value of loaned securities and collateral at period end are disclosed
    on the balance sheet. The Fund invests cash collateral in the Securities
    Lending Investment Fund, which is managed by Brown Brothers Harriman &
    Co., the Fund's custodian.

G. 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.


                                                                              29

2. Management Agreement

PIM manages the Fund's portfolio and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the annual rate of
0.70% of the Fund's average daily net assets up to $500 million; 0.65% of the
next $500 million; and 0.625% of the excess over $1 billion. The basic fee is
subject to a performance adjustment up to a maximum of +/- 0.10% based on the
Fund's investment performance as compared with the Russell 1000[RegTM] Index.
Pursuant to a shareowner vote on April 17, 2003, the benchmark index was
changed to Russell 1000[RegTM] Growth Index effective May 1, 2003. For the six
months ended June 30, 2003, the aggregate performance adjustment resulted in a
decrease to the basic fee of $285,434. The management fee was equivalent to
..59% on an annualized basis, of the average daily net assets for the period.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting, and insurance
premiums, are paid by the Fund. At June 30, 2003, $355,283 was payable to PIM
related to management fees, administrative fees and certain other services.

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 $338,229 in transfer agent
fees payable to PIMSS at June 30, 2003.

4. Distribution and Service Plans

The Fund adopted Plans of Distribution with respect to Class A, Class B Class C
and Class R shares (Class A Plan, Class B Plan, Class C Plan, and Class R 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 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. Pursuant to the Class R Plan, the Fund pays PFD 0.50% of the average
daily net assets attributable to Class R

shares for distribution services. Included in due to affiliates is $237,436 in
distribution fees payable to PFD at June 30, 2003. The Fund also has adopted a
separate service plan for Class R shares (Service Plan). The Service Plan
authorizes the Fund to pay securities dealers, plan administrators or other
services organizations that agree to provide certain services to retirement
plans or plan participants holding shares of the Fund a service fee of up to
0.25% of the Fund's daily net assets attributable to Class R shares held by
such plans.

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 one year of purchase. Class B shares that are redeemed within six 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%.
Redemptions of Class R shares within 18 months of purchase may be subject to a
CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the six months
ended June 30, 2003, CDSCs in the amount of $254,289 were paid to PFD.

5. Expense Offsets

The Fund has entered into certain directed brokerage and expense offset
arrangements resulting in a reduction in the Fund's total expenses. For the six
months ended June 30, 2003, the Fund's expenses were reduced by $19,123 under
such arrangements.

6. Line of Credit Facility

The Fund, along with certain others in the Pioneer Family of Funds (the Funds),
collectively participate in a $50 million committed, unsecured revolving line
of credit facility. Borrowings are used solely for temporary or emergency
purposes. The Fund may borrow up to the lesser of $50 million or the limits set
by its prospectus for borrowings. Interest on collective borrowings is payable
at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an
annual commitment fee for this facility. The commitment fee is allocated among
such Funds based on their respective borrowing limits. For the six months ended
June 30, 2003, the Fund had no borrowings under this agreement.


                                                                              31
