LETTER FROM THE CHAIRMAN 5/31/97
_______________________________________________________________________________
D e a r S h a r e o w n e r ,
- ----------------------------------------------------------------------------
I am pleased to introduce this first report to shareowners of Pioneer Micro-Cap
Fund. This report covers the period from the Fund's inception on February 28,
1997, through the midpoint of its fiscal year on May 31, 1997. On behalf of the
Fund's investment management team, I thank you for your interest.
Pioneer Micro-Cap Fund is a way for investors to participate in the fortunes of
the smallest publicly held companies, those with a capitalization of $300
million or less. Your management team, with the direction of portfolio manager
William "Pete" Taussig, looks for stocks trading at low prices in comparison to
the companies' financial position and long-term prospects. They have a distinct
preference for companies in turnaround situations, or those that are likely
takeover candidates.
You should consider the Fund to be an aggressive portion of your portfolio. Even
though we look for stocks with low valuations, which can prove to be quite
rewarding in the long-term, investing in small companies is an inherently
volatile proposition. That said, your Fund's investment strategy has been
successful so far, and the Fund outperformed small stocks as a whole over its
brief life.
I encourage you to read on to learn more about your Fund and our efforts to
build a solid foundation for long-term success. Please contact your investment
representative, or Pioneer at 1-800-225-6292, if you have questions about
Pioneer Micro-Cap Fund. Thank you for your support.
Respectfully,
/s/ John F. Cogan, Jr.

It is with pleasure that I provide this review of Pioneer Micro-Cap Fund's
growth and progress over the first three months of its life. The Fund was
introduced on February 28, 1997, and reached the halfway point of its fiscal
year on May 31 with more than 4,500 shareowners and $57 million in assets. On
behalf of the entire team of portfolio managers and analysts who contribute to
the Fund, I'd like to thank you for your interest.
Small Company Stocks Surged Late in Period
Small-company stocks did what they do best over the course of Pioneer Micro-Cap
Fund's brief life - quickly change in price. Large stocks dominated the market
for most of the period, with the Dow Jones Industrial Average (DJIA) of 30 big
issues racking up a return of 2.42% in March and April, compared to -4.45% for
the Russell 2000 Index of small stocks. This continued the pattern of the past
year, with investors seeming to have difficulty summoning the discipline to
choose small, less-familiar issues over popular "blue-chip" companies. These
were two frustrating months for those watching the performance of smaller,
lesser-known stocks. For us, however, the dip was timely - lower prices created
some interesting buying opportunities, as we discuss later in this report.
In May, investors began to show more interest in smaller stocks. In fact, the
Russell 2000 rose 11.12% in May, bringing its three-month return to 6.18%. By
contrast, the DJIA returned 4.60% for the month and 7.13% for the quarter. These
swift changes are not uncommon when dealing with smaller stocks, and offer
compelling evidence for remaining invested, rather than attempt to "time" the
stock market.

PORTFOLIO MANAGEMENT DISCUSSION 5/31/97 (continued)
_______________________________________________________________________________
Using "Aggressive Value" Strategy to Build the Portfolio
Our goal for Pioneer Micro-Cap Fund is to provide long-term capital growth. The
Fund invests only in stocks of companies with a market capitalization (that is,
the value of outstanding stock shares) of $300 million or less. Nearly 7,000
U.S. companies fall into this category, giving us a huge base of stocks from
which to choose. Micro-cap companies have the potential for impressive growth
although their stocks can be quite volatile and less liquid than stocks of
larger companies. In fact, as measured by the Merrill Lynch Micro-Cap Index,
micro-caps were the best-performing sector of the U.S. equity market over the 20
years ended December 31, 1996.
We use an "aggressive value" investment style for your Fund. This means we
prefer stocks that are out of favor and selling at relatively low prices - even
though the companies have strong cash flows, strong market shares, solid balance
sheets and proactive management. We look for companies that generate excess cash
flow from their operations, since businesses that regularly turn to the markets
to raise cash are more vulnerable to external factors. Undervalued companies are
what we're seeking, so it isn't enough for a stock to be cheap we want to know
why. Does the company have a legitimate franchise and a defensible competitive
position? Or did it previously enjoy a stock price that exceeded its real value?
We are only interested in the first scenario.
This investment approach means we avoid crowds, and you may not recognize many
of the 46 names in the Fund's portfolio. We prefer to find unique opportunities
offered by lesser-known, often complicated or misunderstood enterprises. Our
favorite companies bring the potential for what we call "double-barreled"
improvement - significant sales growth and expanding profit margins.
Accordingly, we focus on companies in turnaround, transition and special
situations, along with niche firms. We are prepared to be patient, and expect
holdings may take several years to achieve the target prices we set at the time
of purchase.

Technology and Biotechnology Favored
By the close of the period, we had invested 87% of the Fund's assets in stocks,
with only 13% held in short-term cash equivalents. Our target is to have each
holding represent about 2% of the portfolio, and we have been able to do that in
most cases.
To date, the majority of companies that have met our criteria are in the
technology and biotechnology sectors. (As of May 31, technology represented 44%
of the Fund's equity assets, including an 11% position in biotechnology.) These
industries have the potential for fantastic returns if a company succeeds. They
also are areas where psychology and emotion play a big role. When a short-term
problem appears, emotional reactions often push down technology stocks to prices
that are exceedingly attractive on a longer-term basis. A disciplined,
value-oriented investor can profit from these bouts of investor fear.
Just such a break in the market came in March, and again in April. We took the
opportunity to build positions in computer service companies such as Mercury
Interactive (automated client/server testing tools), Broadway & Seymour
(technology business solutions for financial and professional services firms)
and FileNet (document imaging and management software). In electronics, we
selected C.P. Clare (semiconductor switches and relays), while adding DSP
Communications, a developer of chipsets for the wireless market.
Technology-related stocks include MicroAge, a retailer of computers and
equipment. When all was said and done, the technology stocks in the portfolio
quickly rebounded over the past three months.
In the biotechnology world, we look for companies likely to introduce new
products in the next 12-24 months. Here we expect to give firms two or three
years to show results, so we are sanguine about the group's relatively poor
recent performance. Biotechnology holdings include Chirex (an outsource for
biotechnology and pharmaceutical firms), ArQule (chemical compounds for biotech
and drug companies), ImClone Systems (therapeutic products for the treatment of
cancer-related diseases) and Texas Biotechnology (developing a new generation of
therapeutics for the vascular system).

The portfolio also contains a significant number of companies in the financial
sector. Among these are Ocwen Asset Investment, a spin-off of Ocwen Financial.
We used the Fund's flexibility and invested in real estate investment trusts
(REITs). We are especially cognitive of quality when looking at REITs. We want
to see real assets, savvy management and solid financial standing with
fixed-rate, if any, debt. REIT holdings include Bedford Property Investors
(suburban office and industrial properties in the Western U.S.) and Glenborough
Realty Trust, which boasts a well-rounded portfolio of income-producing
properties.
Moving Forward
As we enter the second half of Pioneer Micro-Cap Fund's fiscal year, we expect
to continue much as we have begun. We'll look for companies that meet our strict
value criteria and growth prospects. We'll also monitor the portfolio for stocks
that begin to hit our target prices, or that suffer a significant change in
their fundamental business. Your investment management team is confident that
our aggressive value strategy brings shareowners a real opportunity to
participate in the fast-paced micro-cap market, an opportunity that cannot
easily be replicated without the skill and energy of professional management.
Respectfully,
/s/ William M. Taussig

NOTES TO FINANCIAL STATEMENTS 5/31/97
_______________________________________________________________________________
1. Organization and Significant Accounting Policies
Pioneer Micro-Cap Fund (the Fund) is a Delaware business trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund was organized on December 3, 1996 and commenced
operations on February 28, 1997. Prior to February 28, the Fund had no
operations other than those relating to organizational matters and the initial
capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). The
investment objective of the Fund is to seek long-term growth of capital.
The Fund offers two classes of shares - Class A and Class B shares. Shares of
Class A and Class B 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 and Class B shareholders,
respectively.
The Fund's financial statements have been prepared in conformity with 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 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 on trade date. Each day, 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 and interest income is recorded on the accrual basis.
Temporary cash investments are valued at amortized cost.
18

Pioneer Micro-Cap Fund
_______________________________________________________________________________
_______________________________________________________________________________
Gains and losses on sales of investments are calculated on the identified cost
method for both financial reporting and federal income tax purposes. It is the
Fund's practice to first select for sale those securities that have the
highest cost and also qualify for long-term capital gain or loss treatment for
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
shareholders. Therefore, no federal income tax provision is required.
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.
C. Fund Shares
The Fund records sales and repurchases of its shares on trade date. Net
losses, if any, as a result of cancellations are absorbed by PFD, the
principal underwriter for the Fund and an indirect subsidiary of The Pioneer
Group, Inc. (PGI). PFD earned $22,910 in underwriting commissions on the sale
of fund shares during the period ended May 31, 1997.
D. Class Allocations
Distribution fees are calculated based on the average daily net asset value
attributable to Class A and Class B 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.

_______________________________________________________________________________
NOTES TO FINANCIAL STATEMENTS 5/31/97 (continued)
_______________________________________________________________________________
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 and Class B shares can bear different transfer agent and
distribution fees.
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,
Pioneering Management Corporation (PMC), is responsible for determining that
the value of the collateral remains at least equal to the repurchase price.
F. Deferred Organization Costs
The costs incurred by the Fund in connection with its organization have been
deferred and are amortized on a straight-line basis over a period of up to
five years. If PMC redeems any of its initial investment prior to the end of
the amortization period, the redemption proceeds will be decreased by the pro
rata share of the unamortized expenses as of the date of redemption. The pro
rata share is derived by dividing the number of original shares redeemed by
the total number of original shares outstanding at the time of redemption.
2. Management Agreement
PMC manages the Fund's portfolio and is a wholly owned subsidiary of PGI.
Management fees are calculated daily at the annual rate of 1.10% of the Fund's
average daily net assets.
PMC 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 shares will be reduced
only to the extent that such expenses are reduced for Class A shares. PMC's
agreement is voluntary and temporary and may be revised or terminated at any
time.

_______________________________________________________________________________
In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At May 31, 1997, $9,240 was payable to PMC related to management 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 $52,193 in transfer agent fees payable to PSC at May 31, 1997.
4. Distribution Plans
The Fund adopted a Plan of Distribution for each class of shares (Class A Plan
and Class B 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 Fund's average daily net assets 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, 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 shares. Included in due to affiliates is $31,750 in
distribution fees payable to PFD at May 31, 1997.
Class B shares that are redeemed within six years of purchase are subject to a
CDSC at declining rates beginning at 4.0%, based on the lower of cost or market
value of shares being redeemed. Proceeds from the CDSC are paid to PFD. For the
period ended May 31, 1997, CDSCs in the amount of $2,269 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 period ended May 31, 1997, the
Fund's expenses were reduced by $10,757 under such arrangements.

6. Affiliated Companies
The Fund primarily invests in smaller capitalized company securities that tend
to be more sensitive to changes in earnings expectations and have lower trading
volumes than mid to large capitalized company securities, and as a result, they
may experience more abrupt and erratic price movements. The Fund's investment in
these smaller capitalized companies may exceed 5% of the outstanding voting
stock. Such companies are deemed affiliates of the Fund for financial reporting
purposes. The following summarizes transactions with affiliates of the Fund as
of May 31, 1997:
