[COPYRIGHT]  Karsh, Ottawa

Dear Shareholder:

This is the last letter to you and the other shareholders of Putnam
Global Growth Fund that I will be signing.  After more than 30 years as
Chairman of the Trustees and President of the Putnam Funds, the time has
come for me to step aside. As of July 1, 2000, John Hill will become
Chairman. John is currently an independent Trustee and has served on the
board for the past 14 years. In addition, my son, George Putnam, III,
will take on the role of President. I am confident that the leadership
of the funds will be in exceptionally strong hands.

I will become Chairman Emeritus, remain a Putnam shareholder, and stay
in close touch with the funds. It has been my privilege to serve you.

In one final piece of news, I am pleased to announce the appointment of
Stephen P. Dexter to your fund's management team. Before joining Putnam
in 1999, Steve was with Scudder Kemper Investments, Kemper Financial
Services, and Sears Investment Management. He has 17 years of investment
experience.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees

REPORT FROM THE FUND MANAGERS

Robert Swift

Stephen P. Dexter
Manuel Weiss

A global rally in growth stocks generated strong performance for Putnam
Global Growth Fund in the semiannual period that ended April 30, 2000.
In the final two months of 1999, in particular, stocks in the
telecommunications, media, and technology sectors surged, as investors
recognized the demand by businesses and consumers for new technologies
and services. Our research had identified these new technologies early
on and your fund was well positioned in many innovative companies. The
only surprise was that investors in so many different markets shared a
sudden and simultaneous recognition of these growth opportunities.

Total return for 6 months ended 4/30/00

* GLOBAL ECONOMIC GROWTH PROMPTS INFLATION WORRIES

The market environment was ripe for rewards as the six-month period
opened because of the combination of rising economic growth in the
United States and abroad. Recovery overseas has been steady despite
lagging behind the U.S. rate. The global recovery fueled consumer and
business spending in developed markets and has helped the cyclical
sectors in emerging markets. With global growth on the upswing, and
interest rates moderate, stocks in general looked attractive but growth
stocks especially so. Above all, spending on technology and
communications products -- computers, wireless telephones, networking
equipment, and software -- stoked investor interest in these sectors.

The companies we emphasize in this fund were in favor throughout the
world during the first several months of the period. These companies are
characterized by high rates of earnings growth, strong management,
dominant market positions, and unit growth, which means that their
businesses are expanding. As an example, consider the cellular telephone
market. In many major markets, including the United States, only about
25% of households own cell phones, a figure that could double or triple
in coming years.

While the outlook for these companies has not changed, financial markets
did not remain as optimistic through the end of the period. Unusually
strong growth and low unemployment in the United States caused the
Federal Reserve Board to express concern for price pressures. To head
off these pressures, the Fed raised short-term interest rates three
times in the semiannual period (and once more after it ended). Many
investors began to fear that the Fed's policy would bring about a
recession, which would undercut the business and consumer spending on
technology products. During the final two months of the period, growth
stocks worldwide declined, even as companies in these sectors continued
to achieve high earnings.

* TELECOMMUNICATIONS STOCKS THRIVE AROUND WORLD

The telecommunications industry is fertile with new products and
services and is offering great investment opportunities in many regions.
Even Japan, which has had many business woes in recent years, has its
share of leading telecom companies. It is worth noting in this regard
that Japan is gradually following in the footsteps of the United States;
its economy is shifting from an industrial manufacturing focus and now
favors services and high technology. Increasing numbers of corporations
are restructuring and shutting down industrial facilities. New jobs in
the service sector are being created at the fastest rate in Japan's
history. The only downside to this situation is that the capital
required to finance this transition is being provided by a mountain of
government debt, which is putting some pressure on world capital
markets.

One of the fund's top Japanese holdings and a top performer is NTT
DoCoMo. It is Japan's leading cellular phone service provider, spun off
from its parent company, Nippon Telegraph and Telephone, in 1999. NTT
DoCoMo controls a proprietary technology for wireless data transmission,
including the ability to send e-mail using a cellular telephone. It has
introduced this technology in Japan through its I-mode service.
Originally anticipated to attract 2 million subscribers in its first
year, I-mode is such a hit that sales could reach 10 million. While this
holding, along with others discussed in this report, was viewed
favorably at the end of the period, all are subject to review and
adjustment in accordance with the fund's investment strategy and may
vary in the future.


Morningstar awarded Putnam Global Growth Fund's class A shares 5 out of
5 stars for 10-year performance as of April 30, 2000. This rating put
the fund in the top 10% of the 131 international equity funds rated.

Past performance is not indicative of future results. Morningstar
ratings reflect risk-adjusted performance through 4/30/00 and are
subject to change every month. Morningstar ratings are calculated from a
fund's 3-, 5-, and 10-year returns (with fee adjustments) in excess of
90-day Treasury bill returns and a risk factor that reflects performance
below 90-day Treasury bill returns. For the 3- and 5-year periods the
fund received five stars. There were 1,138 and 687 funds rated,
respectively. Performance of other share classes will vary.


Your fund's global mandate is an advantage because of the global
movement of technology ideas. For example, NTT DoCoMo's proprietary
wireless technology is based upon the intellectual property of a U.S.
company, QUALCOMM, which designs interfaces for wireless communications.
QUALCOMM collects a 5% licensing fee on all the revenues of companies
that manufacture hardware based on its interface. QUALCOMM thus stands
to benefit tremendously as telecommunications shift from primarily
voice-based wireline transmission to data-based wireless transmission.


Vodafone Group seizes growth opportunity

During the past six months, your fund benefited from the largest corporate
merger in Europe's history, Vodafone Group's acquisition of Mannesmann. The
fund owned both stocks. Mannesmann, a German company, triggered the struggle
with a plan to buy Orange, Vodafone's smaller rival in the United Kingdom.
Vodafone fended off the threat by making a hostile bid to buy Mannesmann.
Capital markets saw the benefits of a combination, both stocks rallied, and
Mannesmann management was gradually persuaded to accept a sweetened bid.

Vodafone is now the dominant wireless company in Europe and has a strong
presence in the United States. It has 50 million mobile phone
subscribers and is growing in excess of 20% per year. This acquisition
demonstrates the benefits of our global approach to growth investing, in
which we compare companies and analyze industries on a global basis. It
also demonstrates the opportunities for European companies to expand,
thanks to growing market integration fostered by the introduction of the
euro in 1999.


* FINANCIAL SERVICES OFFER GROWTH IN MANY MARKETS

Although the fund had a large commitment in the technology and
telecommunication areas, it remains fully diversified with attractive
companies in all sectors. The expansion of financial services is a trend
that has benefited several holdings, especially in Europe. Bipop-Carire
has become Italy's largest bank through acquisitions and unit growth. It
is the result of a 1999 merger between Banco Populare di Brescia and
Carire. Bipop-Carire has become a leading distributor of mutual funds,
which are becoming more popular in Italy. This portion of its business
grew by 40% last year. In Germany, one of the fund's largest holdings is
Marschollek, Lautenschlaeger. This brokerage partnership has an
aggressive expansion strategy targeting young German professionals with
high incomes who are new to investing. It offers comprehensive financial
services and is making excellent use of the Web to keep transaction
costs down.

Charles Schwab in the United States has a somewhat similar story. This
company has astutely positioned itself to take advantage of the growing
number of individuals who like to trade stocks online. Schwab charges a
low trading commission and, through its mutual fund supermarket,
provides investors with access to a huge variety of different funds.

These holdings represent 39.1% of the fund's net assets as of 4/30/00.
Portfolio holdings will vary over time.


* STOCKS REMAIN FUNDAMENTALLY SOLID

As we look ahead to the second half of the fund's 2000 fiscal year, we
remain pleased with the fundamental performance of companies in the
portfolio. Most of the fund's holdings reported excellent financial
results for the first quarter of 2000 and remain well positioned for
coming months. Unfortunately market psychology has become more
pessimistic since March because of concerns that efforts by central
banks to smother inflation will also choke off business and consumer
spending on new technology products and services. We are confident,
however, that demand can remain strong without igniting inflation and
that the global economy will continue showing positive growth. Once
markets adjust to these expectations, we believe they will once again
focus on the strong earnings of growth companies.

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 4/30/00, there is no guarantee the fund will
continue to hold these securities in the future. International investing
involves certain risks, including economic instability, political
developments, and currency fluctuations, not present with U.S.
investments.


PERFORMANCE SUMMARY

This section provides information about your fund's performance, which
should always be considered in light of its investment strategy. Putnam
Global Growth Fund is designed for investors seeking capital
appreciation through a globally diversified equity portfolio.

Past performance is no assurance of future results. More recent returns
may be more or less than those shown. 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. For
class C shares, returns for periods prior to their inception are derived
from the historical performance of class A shares, adjusted to reflect
both the CDSC currently applicable to class C shares, which is 1% for
the first year and is eliminated thereafter, and the higher operating
expenses applicable to class C 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.

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 C shares are not subject to an initial sales charge and are
subject to a contingent deferred sales charge only if the shares are
redeemed during the first year.

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 or C shares and assumes redemption at the
end of the period. Your fund's class B 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. The CDSC for class C shares is 1% for one
year after purchase.


COMPARATIVE BENCHMARKS

Morgan Stanley Capital International (MSCI) All-Country World Free Index
is an unmanaged list of global equity securities available to
non-domestic investors, with all values expressed in U.S. dollars.

Consumer price index (CPI) is a commonly used measure of inflation; it
does not represent an investment return.

Securities indexes assume reinvestment of all distributions and interest
payments and do not take in account brokerage fees or taxes. Securities
in the fund do not match those in the indexes and performance of the
fund will differ. It is not possible to invest directly in an index.


A GUIDE TO THE FINANCIAL STATEMENTS

These sections of the report constitute the fund's financial statements.

The fund's portfolio  lists all the fund's investments and their values
as of the last day of the reporting period. Holdings are organized by
asset type and industry sector, country, or state to show areas of
concentration and diversification.

Statement of assets and liabilities  shows how the fund's net assets and
share price are determined. All investment and noninvestment assets are
added together.  Any unpaid expenses and other liabilities are
subtracted from this total. The result is divided by the number of
shares to determine the net asset value per share, which is calculated
separately for each class of shares. (For funds with preferred shares,
the amount subtracted from total assets includes the net assets
allocated to remarketed preferred shares.)

Statement of operations  shows the fund's net investment gain or loss
for the reporting period. This is determined by adding up all the fund's
earnings -- from dividends and interest income -- and subtracting its
operating expenses. This statement also lists any net gain or loss the
fund realized on the sales of its holdings and -- for holdings that
remain in the portfolio -- any change in unrealized gains or losses over
the period.

Statement of changes in net assets  shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number
of the fund's shares. It lists distributions and their sources (net
investment income or realized capital gains) over the current reporting
period and the most recent fiscal year-end. The distributions listed
here may not match the sources listed in the Statement of operations
because the distributions are determined on a tax basis and may be paid
in a different period from the one in which they were earned.

Financial highlights  provide an overview of the fund's investment
results, per-share distributions, expense ratios, net investment income
ratios and portfolio turnover in one summary table, reflecting the five
most recent reporting periods. In a semiannual report, the highlight
table also includes the current reporting period. For open-end funds, a
separate table is provided for each share class.

NOTES TO FINANCIAL STATEMENTS
April 30, 2000 (Unaudited)

Note 1
Significant accounting policies

Putnam Global Growth Fund (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 by
investing primarily in common stocks traded in securities markets
located in a number of foreign countries and in the United States.

The fund offers class A, class B, class C, 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 are subject to a
contingent deferred sales charge, if those shares are redeemed within
six years of purchase. Class C shares are subject to the same fees and
expenses as class B shares, except that class C shares have a one-year
1.00% contingent deferred sales charge and do not convert to class A
shares. 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, class C and class M shares, but do not bear a distribution fee.
Class Y shares are sold to defined contribution plans that invest at
least $150 million in a combination of Putnam funds and other 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 of the financial statements and the reported
amounts of increases and decreases in net assets from operations during
the reporting period. 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. Securities quoted in foreign currencies are translated into U.S.
dollars at the current exchange rate. Short-term investments having
remaining maturities of 60 days or less are stated at amortized cost
which approximates market, 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 Investment Management Inc. 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). Gains or losses on securities sold are determined
on the identified cost basis. Interest income is recorded on the accrual
basis. Dividend income is recorded on the ex-dividend date except that
certain dividends from foreign securities are recorded as soon as the
fund is informed of the ex-dividend date.

E) Foreign currency translation The accounting records of the fund are
maintained in U.S. dollars. The market value of foreign securities,
currency holdings, and other assets and liabilities are recorded in the
books and records of the fund after translation to U.S. dollars based on
the exchange rates on that day. The cost of each security is determined
using historical exchange rates. Income and withholding taxes are
translated at prevailing exchange rates when accrued or incurred. The
fund does not isolate that portion of realized or unrealized gains or
losses resulting from changes in the foreign exchange rate on
investments from fluctuations arising from changes in the market prices
of the securities. Such gains and losses are included with the net
realized and unrealized gain or loss on investments. Net realized gains
and losses on foreign currency transactions represent net realized
exchange gains or losses on closed forward currency contracts,
disposition of foreign currencies and the difference between the amount
of investment income and foreign withholding taxes recorded on the
fund's books and the U.S. dollar equivalent amounts actually received or
paid. Net unrealized appreciation and depreciation of assets and
liabilities in foreign currencies arise from changes in the value of
open forward currency contracts and assets and liabilities other than
investments at the period end, resulting from changes in the exchange
rate.

Investments in foreign securities involve certain risks, including those
related to economic instability, unfavorable political developments, and
currency fluctuations, not present with domestic investments.

F) Forward currency contracts The fund may engage in forward currency
contracts, which are agreements between two parties to buy and sell
currencies at a set price on a future date, to protect against a decline
in value relative to the U.S. dollar of the currencies in which its
portfolio securities are denominated or quoted (or an increase in the
value of a currency in which securities a fund intends to buy are
denominated, when a fund holds cash reserves and short-term
investments). The U.S. dollar value of forward currency contracts is
determined using current forward currency exchange rates supplied by a
quotation service. The market value of the contract will fluctuate with
changes in currency exchange rates. The contract is "marked to market"
daily and the change in market value is recorded as an unrealized gain
or loss. When the contract is closed, the fund records a realized gain
or loss equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed. The fund
could be exposed to risk if the value of the currency changes
unfavorably, if the counterparties to the contracts are unable to meet
the terms of their contracts or if the fund is unable to enter into a
closing position.

G) 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 six months
ended April 30, 2000, the fund had no borrowings against the line of
credit.

H) 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.

I) 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. 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.

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: 0.80% of the
first $500 million of average net assets, 0.70% of the next $500
million, 0.65% of the next $500 million, 0.60% of the next $5 billion,
0.575% of the next $5 billion, 0.555% of the next $5 billion, 0.54% of
the next $5 billion and 0.53% 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 six months ended April 30, 2000, fund expenses were reduced by
$1,147,609 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 $4,017
has been allocated to the fund, and an additional fee for each Trustee's
meeting attended. 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
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 a 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, class C 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%, 1.00% and 1.00% of the average net assets attributable to class
A, class B, class C and class M shares, respectively. The Trustees have
approved payment by the fund at an annual rate of 0.25%, 1.00%, 1.00%
and 0.75% of the average net assets attributable to class A, class B,
class C and class M shares, respectively.

For the six months ended April 30, 2000, Putnam Mutual Funds Corp.,
acting as underwriter received net commissions of $885,664 and $23,646
from the sale of class A and class M shares, respectively and received
$849,651 and $8,694 in contingent deferred sales charges from
redemptions of class B and class C shares. A deferred sales charge of up
to 1% is assessed on certain redemptions of class A shares. For the six
months ended April 30, 2000, Putnam Mutual Funds Corp., acting as
underwriter received $20,940 on class A redemptions.

Note 3
Purchases and sales of securities

During the six months ended April 30, 2000, cost of purchases and
proceeds from sales of investment securities other than short-term
investments aggregated $6,562,285,323 and $6,136,088,095, respectively.
There were no purchases and sales of U.S. government obligations.

Putnam Global Growth Fund
Supplement to Semiannual Report dated 4/30/00
The following information has been prepared to provide class Y shareholders
with a performance overview specific to their holdings. Class Y shares are
offered exclusively to defined contribution plans investing $150 million or
more in one or more of Putnam's funds or private accounts. Performance of
class Y shares, which incur neither a front-end load, distribution fee, nor
contingent deferred sales charge, will differ from performance of class A,
B, C, and M shares, which are discussed more extensively in the semiannual
report.

Please note that past performance is no guarantee of future results.
Returns shown for class Y shares for periods prior to their inception are
derived from the historical performance of class A shares, adjusted to
reflect the initial sales charge currently applicable to class A shares.
These returns have not been adjusted to reflect differences in operating
expenses which, for class Y shares, are lower than the operating expenses
applicable to class A shares. All returns assume reinvestment of
distributions at net asset value. Investment return and principal value
will fluctuate so your shares, when redeemed, may be worth more or less
than their original cost. See full report for information on comparative
benchmarks. If you have questions, please consult your fund prospectus or
call Putnam toll free at 1-800-752-9894.
