Fund highlights


* "The environment for small, emerging-growth companies continues to be
   strong and their valuations are more attractive now than at any other time
   during the past decade. We continue to invest according to the fund's
   stated objectives and the portfolio is positioned to benefit greatly when
   small-cap stocks come back into favor. At this point, the only missing
   ingredient is investor sentiment."

Dear Shareholder:

During periods when the market sectors in which a fund invests fall
temporarily out of favor, it is particularly important for shareholders to
focus on the fund's long-term performance rather than on its results over
the short term. It is also useful to note the fund's standings within its
own peer group. In both respects, we are pleased with Putnam OTC &
Emerging Growth Fund's results and call your attention to the performance
charts that begin on page 9 and the fund's standings within its Lipper
universe, shown on the facing page.

Because of Putnam Management's dedication to adhering firmly to the fund's
stated investment style, we believe it is safe to conclude that given the
current market environment, your fund is performing as it should. During
such times, the fund's management team often seeks out what it sees as
opportunities that may take some time to come to fruition. In the
following report, the managers discuss fiscal 1998 strategy and look at
prospects for fiscal 1999.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
September 16, 1998



Report from the Fund Managers
Michael J. Mufson
Steven L. Kirson

Patience was a virtue during Putnam OTC & Emerging Growth Fund's 1998
fiscal year as we continued to wait for small, emerging-growth stocks to
come back into favor. In the meantime, the fund's returns were
strengthened by strategic stock selection and portfolio positioning that
minimized exposure to troubled Asian markets. For the 12 months ended July
31, 1998, your fund's class A share total returns were 8.30% at net asset
value and 2.06% at public offering price. These are far ahead of the
fund's benchmark, the Russell 2000 Growth Index, which returned -1.32% for
the same 12-month period. For complete performance information, please
refer to the summary that begins on page 9.

Our commentary on fiscal '98 is surprisingly similar to that of a year
ago: large-company stocks were the favorites among investors and delivered
stronger returns than small stocks, which went on a roller-coaster ride.
Emerging-growth companies, in which your fund primarily invests, rebounded
in the second half of the period but still experienced volatility. 

The companies we target are market leaders in dynamic new industries or
market share gainers in established industries that have innovative
products or methods of doing business. Often they are smaller, recently
organized companies -- those that investors have been ignoring for some
time in favor of large, well-established blue-chip companies. Throughout
the period, we made the most of this challenging environment by investing
in stocks of fundamentally strong companies at enticingly low valuations.
We have also selected many stocks that have remained strong in spite of
the market's turbulence. 

* STRONG U.S. ECONOMY BOOSTS RETAIL, MEDIA, ADVERTISING

Throughout the period, the U.S. economy provided fuel for retail stocks in
the form of low unemployment, low inflation, and a high level of consumer
confidence. In your fund's portfolio were retailers that benefited from
the growing number of consumers who are making purchases for their homes.
These stocks were strong performers and included home-product retailers
aimed at affluent customers, such as Williams-Sonoma and Bed Bath and
Beyond. Another portfolio highlight, Michaels Stores, specializes in craft
supplies and home decor items. The company operates more than 500 stores
and has improved its distribution network, store layouts, and inventory
management systems.

Another consistently strong sector throughout the period was media and,
again, the fund profited from companies that offer specialized services.
Univision Communications, for example, is the leading Spanish-language
television broadcaster in the United States. Its operations include the
Univision Network, a Spanish-language broadcast network; the Univision
Television Group, with stations in 12 of the top 15 Hispanic markets; and
Galavision, the most-watched Spanish-language cable network in the
country. Univision continues to attract new advertisers and dominates the
ratings in Spanish-language television.

Also boosting returns were the stocks of two billboard companies,
Universal Outdoor Holdings, which recently was acquired by Clear Channel
Communications, and Lamar Advertising, which operates in 34 states and
Canada. Lamar announced record revenues and operating cash flow for its
1998 second quarter. While these holdings, along with others discussed in
this report, were viewed favorably at the end of the fiscal period, all
are subject to review and adjustment in accordance with the fund's
investment strategy and may vary in the future.

* FUND PROFITS FROM DEMAND FOR OUTSOURCING

Another trend throughout the period was an increasing demand from
corporations for information systems talent. Rather than hiring full-time
employees, more firms are looking to companies that can provide customized
computer consulting, training, and education services. A number of stocks
in the portfolio benefited from this trend, especially as the demand for
technical specialists greatly exceeded the supply.

Whittman-Hart, for example, helps companies improve productivity and
marketplace performance through the strategic use of information
technology. Recently named by Forbes magazine as one of the 200 best small
companies in America, it has 16 branch offices throughout the United
States and in the United Kingdom. Two other computer services companies --
Ciber and Keane -- have also reaped the rewards of strong demand for their
services. Both companies provide comprehensive technical support as well
as tools to help companies fix year 2000 glitches. On the software side of
the equation, Peregrine Systems, Inc. and Platinum Technology provide
tools to automate the management of complex information systems.

* TELECOMMUNICATIONS STOCKS THRIVE ON LOOSENED RESTRICTIONS

For some time now, we have discussed the positive effects of the
Telecommunications Act of 1996 on media and communications stocks. The
legislation, which loosened many industry restrictions, has contributed to
the success of many emerging-growth companies in the fund's portfolio. Of
particular note, once again, are competitive local exchange carriers, or
CLECs. These companies compete with larger providers, such as the Bell
Operating Companies, in local markets. As a result of the
Telecommunications Act, CLECs have been able to enter these markets on a
much wider basis. The number of CLECs entering the market is increasing
rapidly, resulting in a new wave of competition.

McLeodUSA, Inc., a telecommunications services company in the Midwest,
increased its local telephone lines by 145% in the second quarter of 1997
alone. The company continues to capture business from the existing
telephone companies in local markets and is adding miles of new
fiber-optic lines in preparation for more new customers. 

Nextlink Communications is another CLEC that is rapidly increasing its
telephone lines to keep up with an onslaught of new customers. Intermedia
Communications, yet another impressive player in the CLEC market, has one
of the best data networks in the United States.

* LOOKING TO FISCAL '99 WITH OPTIMISM

We enter fiscal 1999 prepared for more market turbulence, and yet we are
optimistic about the positioning of the fund's portfolio. We believe
small-cap growth stocks - with their attractive valuations and fundamental
strengths - are poised for a rebound. Of course, the recovery time for
these stocks cannot be predicted. After much practice in patiently waiting
for the emerging-growth sector to deliver more powerful returns, we are
prepared to wait some more. We'll continue to rely on our bottom-up
process of stock selection, in which we carefully analyze individual
stocks rather than investing solely based on overall trends. And finally,
we expect to minimize the fund's exposure to troubled foreign markets
while keeping an eye on the long-term growth potential of the fund's
holdings.

The views expressed here are exclusively those of Putnam Management. They
are not meant as investment advice. Although the described holdings were
viewed favorably as of 7/31/98, there is no guarantee the fund will
continue to hold these securities in the future. This fund invests a
portion of its assets in small to midsize companies. Such investments
increase the risk of greater price fluctuations.

Past performance is no assurance of future results. Returns for class A
and class M shares reflect the current maximum initial sales charges of
5.75% and 3.50%, respectively. Class B share returns for the 1-, 5-, and
10-year (where available) and life-of-fund periods reflect the applicable
contingent deferred sales charge (CDSC), which is 5% in the first year,
declines to 1% in the sixth year, and is eliminated thereafter. Returns
shown for class B and class M shares for periods prior to their inception
are derived from the historical performance of class A shares, adjusted to
reflect both the initial sales charge or CDSC if any, currently applicable
to each class and in the case of class B and class M shares, the higher
operating expenses applicable to such shares. All returns assume
reinvestment of distributions at NAV. Investment return and principal
value will fluctuate so that an investor's shares when redeemed may be
worth more or less than their original cost.

*Putnam Management has recently undertaken a review of benchmarks for
 various funds. This index will replace the Russell 2000 Index as a
 benchmark for this fund because Putnam Management has determined that the
 securities tracked by this index more accurately reflect the types of
 securities generally held by the fund.

Performance data represent past results, do not reflect future
performance, and will differ for each share class. Investment returns and
principal value will fluctuate so that an investor's shares, when sold,
may be worth more or less than their original cost. See first page of
performance section for performance calculation method.

TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested all
distributions in the fund.

Class A shares are generally subject to an initial sales charge.

Class B shares may be subject to a sales charge upon redemption.

Class M shares have a lower initial sales charge and a higher 12b-1 fee
than class A shares and no sales charge on redemption.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 5.75% maximum sales charge for class A
shares and 3.50% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of class B shares and assumes redemption at the end of the
period. Your fund's CDSC declines from a 5% maximum during the first year
to 1% during the sixth year. After the sixth year, the CDSC no longer
applies.

Report of independent accountants
For the fiscal year ended July 31, 1998


To the Trustees and Shareholders of 
Putnam OTC & Emerging Growth Fund 

In our opinion, the accompanying statement of assets and liabilities,
including the portfolio of investments owned, and the related statements
of operations and of changes in net assets and the financial highlights
present fairly, in all material respects, the financial position of Putnam
OTC & Emerging Growth Fund (the "fund") at July 31, 1998, and the results
of its operations, the changes in its net assets and the financial
highlights for the periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the fund's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted
our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which
included confirmation of investments owned at July 31, 1998 by
correspondence with the custodian, provide a reasonable basis for the
opinion expressed above.

Notes to financial statements
July 31, 1998


Note 1
Significant accounting policies

Putnam OTC & Emerging Growth (the "fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The fund seeks capital appreciation through
investments in common stocks of small to medium-sized emerging growth
companies traded in the over-the-counter (OTC) market and common stocks of
emerging growth companies listed on securities exchanges.

The fund offers class A, class B, class M and class Y shares. Class A
shares are sold with a maximum front-end sales charge of 5.75%. Class B
shares, which convert to class A shares after approximately eight years,
do not pay a front-end sales charge but pay a higher ongoing distribution
fee than class A shares, and may be subject to a contingent deferred sales
charge, if those shares are redeemed within six years of purchase. Class M
shares are sold with a maximum front end sales charge of 3.50% and pay an
ongoing distribution fee that is higher than class A shares but lower than
class B shares. Class Y shares, which are sold at net asset value, are
generally subject to the same expenses as class A, class B and class M
shares, but do not bear a distribution fee. Class Y shares are sold to
defined contribution plans that initially invest at least $250 million in
a combination of Putnam Funds and other certain accounts managed by
affiliates of Putnam Investment Management, Inc. ("Putnam Management"),
the fund's Manager, a wholly-owned subsidiary of Putnam Investments, Inc.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if the fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

The following is a summary of significant accounting policies consistently
followed by the fund in the preparation of its financial statements. The
preparation of financial statements is in conformity with generally
accepted accounting principles and requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities. Actual results could differ from those estimates.

A) Security valuation Investments for which market quotations are readily
available are stated at market value, which is determined using the last
reported sale price, or, if no sales are reported -- as in the case of some
securities traded over-the-counter -- the last reported bid price.
Short-term investments having remaining maturities of 60 days or less are
stated at amortized cost which approximates market value, and other
investments are stated at fair value following procedures approved by the
Trustees.

B) Joint trading account Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the fund may transfer uninvested cash
balances into a joint trading account along with the cash of other
registered investment companies and certain other accounts managed by
Putnam Management. These balances may be invested in one or more
repurchase agreements and/or short-term money market instruments.

C) Repurchase agreements The fund, or any joint trading account, through
its custodian, receives delivery of the underlying securities, the market
value of which at the time of purchase is required to be in an amount at
least equal to the resale price, including accrued interest. Collateral
for certain tri-party repurchase agreements is held at the counterparty's
custodian in a segregated account for the benefit of the fund and the
counterparty. Putnam Management is responsible for determining that the
value of these underlying securities is at all times at least equal to the
resale price, including accrued interest.

D) Security transactions and related investment income Security
transactions are accounted for on the trade date (date the order to buy or
sell is executed). Interest income is recorded on the accrual basis.
Dividend income is recorded on the ex-dividend date.

E) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintain an asset coverage ratio of at least 300% and
borrowings must not exceed prospectus limitations. For the year ended July
31, 1998, the fund had no borrowings against the line of credit.

F) Federal taxes It is the policy of the fund to distribute all of its
taxable income within the prescribed time and otherwise comply with the
provisions of the Internal Revenue Code applicable to regulated investment
companies. It is also the intention of the fund to distribute an amount
sufficient to avoid imposition of any excise tax under Section 4982 of the
Internal Revenue Code of 1986, as amended. Therefore, no provision has
been made for federal taxes on income, capital gains or unrealized
appreciation on securities held nor for excise tax on income and capital
gains.

G) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date.
Capital gain distributions, if any, are recorded on the ex-dividend date
and paid at least annually. The amount and character of income and gains
to be distributed are determined in accordance with income tax regulations
which may differ from generally accepted accounting principles.

These differences include permanent differences of net operating loss and
losses on wash sale transactions. Reclassifications are made to the fund's
capital accounts to reflect income and gains available for distribution
(or available capital loss carryovers) under income tax regulations. For
the year ended July 31, 1998, the fund reclassified $37,778,267 to
decrease accumulated net investment loss and $37,778,267 to decrease
paid-in-capital. The calculation of net investment income per share in the
financial highlights table excludes these adjustments.

Note 2
Management fee, administrative services,
and other transactions

Compensation of Putnam Management, for management and investment advisory
services is paid quarterly based on the average net assets of the fund.
Such fee is based on the following annual rates: 0.70% of the first $500
million of average net assets, 0.60% of the next $500 million, 0.55% of
the next $500 million, 0.50% of the next $5 billion, 0.475% of the next $5
billion, 0.455% of the next $5 billion, 0.44% of the next $5 billion, and
0.43% thereafter.

The fund reimburses Putnam Management an allocated amount for the
compensation and related expenses of certain officers of the fund and
their staff who provide administrative services to the fund. The aggregate
amount of all such reimbursements is determined annually by the Trustees.

Custodial functions for the fund's assets are provided by Putnam Fiduciary
Trust Company (PFTC), a subsidiary of Putnam Investments, Inc. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

For the year ended July 31, 1998, fund expenses were reduced by $1,358,313
under expense offset arrangements with PFTC and brokerage service
arrangements. Investor servicing and custodian fees reported in the
Statement of operations exclude these credits. The fund could have
invested a portion of the assets utilized in connection with the expense
offset arrangements in an income producing asset if it had not entered
into such arrangements.

Each Trustee of the fund receives an annual Trustee fee, of which $3,500
has been allocated to the fund, and an additional fee for each Trustee's
meeting attended. Trustees who are not interested persons of Putnam
Management and who serve on committees of the Trustees receive additional
fees for attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees Fees payable on or after July 1, 1995. The deferred fees remain
in the fund and are invested in certain Putnam funds until distribution in
accordance with the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as Trustee for at least five years. Benefits under the Pension Plan
are equal to 50% of the Trustee's average total retainer and meeting fees
for the three years preceding retirement. Pension expense for the fund is
included in Compensation of Trustees in the Statement of operations.
Accrued pension liability is included in Payable for compensation of
Trustees in the Statement of assets and liabilities.

The fund has adopted distribution plans (the "Plans") with respect to its
class A, class B and class M shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to compensate
Putnam Mutual Funds Corp., a wholly-owned subsidiary of Putnam Investments
Inc., for services provided and expenses incurred by it in distributing
shares of the fund. The Plans provide for payments by the fund to Putnam
Mutual Funds Corp. at an annual rate up to 0.35%, 1.00%, and 1.00% of the
average net assets attributable to class A, class B, and class M shares,
respectively. The Trustees have approved payment by the fund at an annual
rate of 0.25%, 1.00% and 0.75% of the average net assets attributable to
class A, class B and class M shares respectively.

For the year ended July 31, 1998, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $1,166,732 and $48,261 from the
sale of class A and class M shares, respectively and received $2,687,613
in contingent deferred sales charges from redemptions of class B shares. A
deferred sales charge of up to 1% is assessed on certain redemptions of
class A shares. For the year ended July 31, 1998, Putnam Mutual Funds
Corp., acting as underwriter received $79,981 on class A redemptions.

Note 3
Purchases and sales of securities

During the year ended July 31, 1998, purchases and sales of investment
securities other than short-term investments aggregated $4,033,618,500 and
$4,038,249,787 respectively. There were no purchases and sales of U.S.
government obligations. In determining the net gain or loss on securities
sold, the cost of securities has been determined on the identified cost
basis.

Note 4
Capital shares

At July 31, 1998, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:
