 LETTER FROM THE CHAIRMAN 9/30/00
 Dear Shareowner,
--------------------------------------------------------------------------------

By the time you read this report, we will all know how the financial markets
responded to this year's election. Market reactions to presidential elections
are often short-lived; after digesting the outcome, investors return to
thinking about the factors that influence their portfolios: the economic
outlook, the impact of higher interest rates and selecting the right
investments.

In addition to squeezing corporate profits, higher interest rates cause
consumers to postpone or reduce nonessential purchases. The cumulative weight
of these individual decisions and today's high energy prices can already be
seen in spotty retail activity and lower sales of new cars and homes. As a
result, the economy will probably back off from its extraordinary recent growth
pace to lower, more sustainable levels.

Now could be a perfect time to straighten up your financial house. Some of the
steps you can take include contributing as much as you can to your company's
retirement programs, deciding whether a Roth or Traditional IRA might be a
better choice in your circumstances, and reassessing your investments in the
light of changing markets. Your investment professional is your best guide to
making these important decisions.

An important announcement from Pioneer

I'm very happy to report that, on October 24, 2000, Pioneer Group, Inc. was

Italy's largest banking groups, with assets under management of over $150

organization with the reputation and breadth of UniCredito. Its flourishing
investment management business will be combined with Pioneer's U.S. and
European investment operations to form a truly world class investment asset
management company.

Sincerely,


/s/  John F. Cogan, Jr.

PORTFOLIO MANAGEMENT DISCUSSION 9/30/00

With the world's major stock market indices in negative territory for the six
months ended September 30, 2000, global investors might think that the first
year of the new millennium will end much differently than it began. However,
despite near term uncertainty, market observers believe the economic conditions
are in place for a resumption of an upward course. In the following interview,
portfolio manager Patrick M. Smith explains the factors that influenced Pioneer
World Equity Fund's performance and his expectations going forward.

Q:  What contributed to the reversal in global stock markets?

A:  The first half of your Fund's fiscal year comes on the heels of March's
    dramatic correction in the technology sector, when stocks quickly lost
    much of the unprecedented gains they had amassed in the previous months.
    Generally speaking, the six months ending September 30, 2000 were marked
    by the flight of investors out of newer technology stocks into shares of
    more established computer makers and traditional industrial companies.
    After a brief rally in August, technology and telecommunication stocks
    fell sharply again, when several marquis companies hinted that upcoming
    earnings might fall short of expectations.

    Other factors contributed to the demise of stock prices worldwide. High
    oil prices are spooking investors - raising inflation concerns in
    developed nations (particularly the United States) and choking economic
    growth in Asian countries, which are still recovering from the 1997
    crisis. In addition, weak currencies, particularly the euro, are pinching
    corporate profits. Geographically, your Fund was also hurt by its limited
    exposure to the stronger performing (albeit negative) U.S. market for the
    six months. Of course, there were bright spots too. The Fund's financial,
    health care and oil sectors turned in strong performances, as nervous
    investors preferred these more defensive, undervalued stocks to
    high-growth investments. However, their positive momentum was not enough
    to stem the overwhelmingly negative sentiment overshadowing global
    markets.

    For the six months ending September 30, 2000, Class A, B and C shares
    generated total returns of -13.31%, -13.70% and -13.71%, respectively, at
    net asset value. The MSCI World Index posted a return of -8.39%. The 151
    global funds tracked by Lipper, Inc. retreated, on

6
<PAGE>
Pioneer World Equity Fund

    average, -7.69% for the same period. (Lipper is an independent firm that
    measures mutual fund performance.)

Q:  Why did the euro continue to decline?

A:  In large part, the euro's decline can be attributed to the flight of capital
    from Europe into business investment worldwide, particularly the vibrant
    U.S. market. The euro has lost over 25% of its value against the dollar
    since its inauguration 21 months ago. European companies are purchasing
    American businesses big and small in record numbers, including Deutsche
    Telekom's proposed $50.7 billion takeover of wireless communications
    company VoiceStream Wireless Corp. and Unilever Group's purchase of Ben &
    Jerry's Homemade Inc. As European companies buy strategic U.S. assets to
    build their international presence, they are converting euros into dollars
    to complete the deals - bolstering the U.S. dollar and depressing the
    euro.

    At some juncture, Europe will be seen as a buying opportunity. Today,
    Europe is delivering its best economic performance in years, and we think
    it's only a matter of time before the financial markets begin to support
    the euro in force. We think the timing of this reception will depend on
    Europe's ability to modernize its business environment and foster the
    building of a New Economy.

Q:  As demand for high-tech and telecommunications stocks has waned, prospects
    for less glamorous, undervalued companies have improved. Why is that?

A:  Investors have shifted from a growth-at-any-cost mentality into a decidedly
    more conservative, value-conscious mode in recent months. This change of
    heart is understandable given the dramatic correction in the prices of
    technology and telecommunication stocks and the ongoing volatility in
    global markets. Financial stocks in the United States and Europe, which
    had been under pressure early in the period when interest rates were
    trending up, rallied. The Fund's investments in Manulife Financial Corp.
    (Canada), Mellon Bank Corp. (United States), Royal Bank of Scotland,
    Amvescap (United Kingdom) and Julius Baer Holding Ltd. (Switzerland)
    climbed dramatically over the six-month period. Health care holdings also
    delivered strong results. Aventis (France) is one of the largest and most
    undervalued pharmaceutical


                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 9/30/00                           (continued)

    companies in Europe and currently holds patents on several very successful
    drugs. Human Genome (United States) and Qiagen NV (The Netherlands) are
    benefiting from the ongoing research in the biotechnology sector.

    Soaring oil prices may be curbing profit expectations for some industries,
    particularly those with high transportation costs, but the ability of the
    Organization of Petroleum Exporting Countries (OPEC) to better manage
    production decisions is boosting earnings growth for energy-related
    companies. With markets anticipating relatively consistent oil prices for
    the foreseeable future, Fund holdings Petrobras Brasileiro (Brazil),
    Canadian Natural Resources, ENI (Italy) and Shell Transport & Trading Co.
    (United Kingdom) appreciated nicely.

Q:  Are you still optimistic about prospects for technology, media and
    telecommunication stocks in spite of their correction?

A:  Absolutely. Today, the markets are telling us that investors' expectations
    for these stocks are less exuberant than they were earlier this year.
    While we welcomed the nascent rise of these stocks last winter, we knew
    these sectors were just as vulnerable to investors' expectations on the
    downside. This is not to say that their prospects are not strong. Quite
    the contrary. We believe long-term growth prospects are as potent as ever.
    Short-term, however, investors are punishing companies for earnings
    reports that do not meet their impossible expectations. We anticipate the
    Fund will maintain a considerable weighting in these sectors for the
    foreseeable future.

Q:  What is your outlook?

A:  I remain very upbeat. The International Monetary Fund recently revised its
    projection for world economic growth for 2000 upward to 4.7% - the fastest
    in 12 years. In the same breath, however, I am keeping a close eye on the
    U.S. economy for signs of a soft landing and positive interest rate
    movement. Europe has all the ingredients for stronger growth, but leaders
    must make the necessary reforms to convince investors that they are
    committed to a true European currency.

Pioneer World Equity Fund

NOTES TO FINANCIAL STATEMENTS 9/30/00 (unaudited)

1. Organization and Significant Accounting Policies

Pioneer World Equity Fund (the Fund) is a Delaware business trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. After shareholder and regulatory approval, UniCredito
Italiano S.p.A. completed its acquisition of the Pioneer Group, Inc. (PGI) on
October 24, 2000. The investment objective of the Fund is to seek long-term
growth of capital.

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 shareholders, respectively.

The Fund's financial statements have been prepared in conformity with
accounting principles generally accepted in the United States 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 value asset
  value is computed once daily, on each day the New York 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. Trading in foreign securities is substantially completed each
  day at various times prior to the close of the Exchange. The values of such
  securities used in computing the net asset value of the Fund's shares are
  determined as of such times. Dividend income is recorded on the ex-dividend
  date, except that certain

                                                                              25
<PAGE>
Pioneer World Equity Fund

NOTES TO FINANCIAL STATEMENTS 9/30/00 (unaudited)                  (continued)

  dividends from foreign securities where the ex-dividend date may have passed
  are recorded as soon as the Fund is informed of the ex-dividend data in the
  exercise of reasonable diligence. Interest income is recorded on the accrual
  basis, net of unrecoverable foreign taxes withheld at the applicable country
  rates. 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.

  The Fund's investments in emerging markets or countries with limited or
  developing markets may subject the Fund to greater degree of risk than in a
  developed market. Risks associated with these developing markets include
  political, social or economic factors and may affect the price of the Fund's
  investments and income generated by these investments, as well as the Fund's
  ability to repatriate such amounts. In addition, delays are common in
  registering transfers of securities in India, and the Fund may be unable to
  sell portfolio securities until the registration process is completed.


B. Foreign Currency Translation

  The books and records of the Fund are maintained in U.S. dollars. Amounts
  denominated in foreign currencies are translated into U.S. dollars using
  current exchange rates.

  Net realized gains and losses on foreign currency transactions represent,
  among other things, the net realized gains and losses on foreign currency
  contracts, disposition of foreign currencies and the difference between the
  amount of income accrued and the U.S. dollar actually received. Further, the
  effects of changes in foreign currency exchange rates on investments are not
  segregated in the statement of operations from the effects of changes in
  market price of those securities but are included with the net realized and
  unrealized gain or loss on investments.


C. Forward Foreign Currency Contracts

  The Fund enters into forward foreign currency contracts (contracts) for the
  purchase or sale of a specific foreign currency at a fixed price on a future
  date as a hedge or cross-hedge against either specific investment
  transactions (settlement hedges) or portfolio positions (portfolio hedges).
  All contracts are marked to market daily at the applicable

26
<PAGE>
Pioneer World Equity Fund

  exchange rates, and any resulting unrealized gains or losses are recorded in
  the Fund's financial statements. The Fund records realized gains and losses
  at the time a portfolio hedge is offset by entry into a closing transaction
  or extinguished by delivery of the currency. Risks may arise upon entering
  into these contracts from the potential inability of counterparties to meet
  the terms of the contract and from unanticipated movements in the value of
  foreign currencies relative to the U.S. dollar.

  As of September 30, 2000 the Fund had no outstanding portfolio hedges.

D. 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
  shareholders. Therefore, no federal income tax provision is required.

  In addition to the requirements of the Internal Revenue Code, the Fund may
  also be required to pay local taxes on the repatriation of certain foreign
  currencies and/or net realized capital gains in certain countries. During
  the six months ended September 30, 2000, the Fund paid no such taxes.

  In determining the daily net asset value, the Fund estimates the reserve for
  such taxes, if any, associated with investments in certain countries. The
  estimated reserve for capital gains taxes, if any, is based on the net
  unrealized appreciation on certain portfolio securities, the holding periods
  of such securities and the related tax rates, tax loss carryforward (if
  applicable) and other such factors. As of September 30, 2000, the Fund had
  no reserve for capital gains taxes. The estimated reserve for repatriation
  of foreign currencies is based on the principal balances and/or unrealized
  appreciation of applicable securities, the holding period of such
  investments and the related tax rates and other such factors. As of
  September 30, 2000, the Fund had no reserve related to taxes on the
  repatriation of foreign currencies.

  The characterization of distributions to shareholders 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.


                                                                              27

NOTES TO FINANCIAL STATEMENTS 9/30/00 (unaudited)                  (continued)

E. Fund Shares

  The Fund records sales and repurchases of its shares as of trade date.
  Pioneer Fund Distributors, Inc. (PFD), the principal underwriter for the
  Fund and an indirect subsidiary of The Pioneer Group, Inc. (PGI), earned $51
  in underwriting commissions on the sale of Fund shares during the six months
  ended September 30, 2000.

F. Class Allocations

  Distribution fees are calculated based on the average daily net asset values
  attributable to Class A, Class B and Class C shares of the Fund,
  respectively. Shareholders of each class share all expenses and fees paid to
  the transfer agent, Pioneering Services Corporation (PSC), for their
  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 allocated daily to each class of shares
  based on the respective percentage of adjusted net assets at the beginning
  of the day.

  Distributions to shareholders 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.

G. Repurchase Agreement

  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.

2. Management Agreement

PIM manages the Fund's portfolio and is a wholly owned subsidiary of PGI.
Management fees are calculated daily at the annual rate of 1.00% of the Fund's
average daily net assets up to $300 million; 0.85% of the next $200 million;
and 0.75% of the excess over $500 million.


28
<PAGE>
Pioneer World Equity Fund

PIM has agreed not to impose a portion of its management fee and to assume
other operating expenses of the Fund to the extent necessary to limit Class A
expenses to 1.75% of the average daily net assets attributable to Class A
shares; the portion of the Fund-wide expenses attributable to Class B and Class
C shares will be reduced only to the extent that such expenses are reduced for
Class A shares. PIM's agreement is voluntary and temporary and may be revised
or terminated at any time.

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, 2000, $24,882 was payable to
PIM related to management fees, administrative fees and certain other services.

3. Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer
agent and shareholder services to the Fund at negotiated rates. Included in due
to affiliates is $17,331 in transfer agent fees payable to PSC at September 30,
2000.

4. Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the average daily net assets attributable to Class A
shares in reimbursement of its actual expenditures to finance activities
primarily intended to result in the sale of Class A shares. Pursuant to the
Class 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 $28,637
in distribution fees payable to PFD at September 30, 2000.

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 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

                                                                              29
<PAGE>
Pioneer World Equity Fund

NOTES TO FINANCIAL STATEMENTS 9/30/00 (unaudited)                  (continued)

are subject to a CDSC of 1.00%. Proceeds from the CDSC are paid to PFD. For the
six months ended September 30, 2000, CDSCs in the amount of $42,203 were paid
to PFD.

5. Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended
September 30, 2000, the Fund's expenses were reduced by $6,483 under such
arrangements.

6. Line of Credit Facility

The Fund, along with certain other Funds 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
of up to $25 million is payable at the Federal Funds Rate plus 3/8% on an
annualized basis, or at the Federal Funds Rate plus 1/2% if the borrowing
exceeds $25 million at any one time. The Funds pay an annual commitment fee for
this facility. The commitment fee is allocated among such Funds based on their
respective borrowing limits.

The average daily amount of borrowings outstanding during the six months ended
September 30, 2000 was $34,754. The average daily shares outstanding during the
period were 2,433,448 resulting in an average borrowing of $.01 per share. The
related weighted average annualized interest rate for the period was 7.10%, and
the total interest expense on such borrowings was $1,764.

PROGRAMS AND SERVICES FOR PIONEER SHAREOWNERS

Your investment professional can give you additional information on Pioneer's
programs and services. If you want to order literature on any of the following
items directly, simply call Pioneer at 1-800-225-6292.

FactFone(SM)

Our automated account information service, available to you 24 hours a day,
seven days a week. FactFone gives you a quick and easy way to check fund share
prices, yields, dividends and distributions, as well as information about your
own account. Simply call 1-800-225-4321. For specific account information, have
your 13 - digit account number and four-digit personal identification number at
hand.

90-Day Reinstatement Privilege (for Class A Shares)

Enables you to reinvest all or a portion of the money you redeem from your
Pioneer account - without paying a sales charge - within 90 days of your
redemption. You have the choice of investing in any Pioneer fund, as long as
you meet its minimum investment requirement.

Investomatic Plan

An easy and convenient way for you to invest on a regular basis. All you need
to do is authorize a set amount of money to be moved out of your bank account
into the Pioneer fund of your choice. Investomatic also allows you to change
the dollar amount, frequency and investment date right over the phone. By
putting aside affordable amounts of money regularly, you can build a long-term
investment - without sacrificing your current standard of living.

Payroll Investment Program (PIP)

Lets you invest in a Pioneer fund directly through your paycheck. All that's
involved is for your employer to fill out an authorization form allowing
Pioneer to deduct from participating employees' paychecks. You specify the
dollar amount you want to invest into the Pioneer fund(s) of your choice.

Automatic Exchange Program

A simple way to move money from one Pioneer fund to another over a period of
time. Just invest a lump sum in one fund, and select the other Pioneer funds
you wish to invest in. You choose the amounts and dates for Pioneer to sell
shares of your original fund and use the proceeds to buy shares of the other
funds you have chosen. Over time, your investment will be shifted out of the
original fund. (Automatic Exchange is available for originating accounts with a
balance of $5,000 or more.)

Directed Dividends

Lets you invest cash dividends from one Pioneer fund to an account in another
Pioneer fund with no sales charge or fee. Simply fill out the applicable
information on a Pioneer Account Options Form. (This program is available for
dividend payments only; capital gains distributions are not eligible at this
time.)

Direct Deposit

Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.

Systematic Withdrawal Plan (SWP)

Lets you establish automatic withdrawals from your account at set intervals.
You decide the frequency and the day of the month you want. Pioneer will send
the proceeds by check to the address you designate, or electronically to your
bank account. You also can authorize Pioneer to make the redemptions payable to
someone else. (SWPs are available for accounts with a value of $10,000 or
more.)

RETIREMENT PLANS FROM PIONEER

Pioneer has a long history of helping people work toward their retirement
goals, offering plans suited to the individual investor and businesses of all
sizes. For more information on Pioneer retirement plans, contact your
investment professional, or call Pioneer at 1-800-622-0176.

Individual Plans

Individual Retirement Account (IRA)

An IRA is a tax-favored account that allows anyone under age 70-1/2 with earned
income to contribute up to $2,000 annually. Spouses may contribute up to $2,000
annually into a separate IRA, for a total of $4,000 per year for a married
couple. Earnings are tax-deferred, and contributions may be tax-deductible.

Roth IRA

The Roth IRA came about as part of the Taxpayer Relief Act of 1997 and became
available to investors in 1998. Contributions, up to $2,000 a year, are not
tax-deductible, but earnings are tax-free for qualified withdrawals.

401(k) Plan

The traditional 401(k) plan allows employees to make pre-tax contributions
through payroll deduction, up to $10,500 per year or 25% of pay, whichever is
less. Employers may contribute.

SIMPLE (Savings Incentive Match Plan for Employees) IRA Plan

Businesses with 100 or fewer eligible employees can establish a plan; it
resembles a traditional 401(k), but has no administration costs. Employees can
make pre-tax contributions of up to $6,000 per year, and an employer
contribution is required.

403(b) Plan

Also known as a Tax-Sheltered Account (TSA), a 403(b) plan is available only to
employees of public schools, not-for-profit hospitals and certain other
tax-exempt organizations. A 403(b) plan lets employees set aside a portion of
their salary, before taxes, through payroll deduction.

Simplified Employee Pension Plan (SEP)

SEPs let self-employed people and small-business owners make tax-deductible
contributions of up to 15% of their income. Generally, employers must
contribute the same percentage of pay for themselves and any eligible
employees; contributions are made directly to employees' IRAs. SEPs are easy to
administer and can be an especially good choice for firms with few or no
employees.

Profit Sharing Plan

Profit sharing plans offer companies considerable flexibility, allowing them to
decide each year whether a contribution will be made and how much, up to 15% of
each participant's pay. These plans can include provisions for loans and
vesting schedules.

Age-Weighted Profit Sharing Plan

Like traditional profit sharing plans, employer contributions are flexible, but
age-weighted plans allocate contributions based on both age and salary.
Age-weighted plans are designed for employers who want to maximize their own
contributions while keeping contributions to employees affordable.

Money Purchase Pension Plan (MPP)

Money purchase plans are similar to profit-sharing plans, but allow for higher
annual contributions - up to 25% of pay. MPPs aren't as flexible as profit
sharing plans; a fixed percentage of pay must be contributed each year,
determined when the plan is established. Businesses often set up both MPPs and
profit sharing plans.







Most retirement plan withdrawals must meet specific conditions to avoid
penalties.
