Fund highlights

* "[T]he fund is consistent in devoting most assets to mid-caps,

  stocks, which have been market darlings for the last 12 months. This 
  even-keeled strategy has kept the fund away from performance extremes.

Dear Shareholder:

As the extraordinary resiliency of the current bull market in
large-capitalization stocks continued, Putnam Vista Fund's focus on
medium-capitalization stocks, which have provided rewarding results over the
long term, became something of a handicap. Your fund's performance for the 12
months ended July 31, 1997, is respectable but falls short of the expectations
fostered by the ongoing strength of large-capitalization stocks.

Two changes have been made within your fund's management team since our last
report to you. Carol McMullen, Chief Investment Officer of Putnam's Core
Growth Equity Group is lead manager following the departure of Jennifer
Silver. Carol joined Putnam in 1995, was previously with Baring Asset
Management and Citicorp Investment Management and has over 17 years of
investment experience.

Although C. Kim Goodwin, a recent addition, has also departed, Anthony
Santosus, a team member since 1994 and David Santos, who has been with Putnam
for 11 years, remain co-managers with Carol. They are supported by seven
dedicated analysts as well as the 40 who comprise our Global Research
department. We are confident that the combined expertise of these
professionals will ensure continuity of the fund's management style.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
September 18, 1997



Report from the Fund Managers
Carol McMullen, lead manager
Anthony C. Santosus
David J. Santos

The stock market sprinted ahead at a steady pace, setting one market high
after another during the 12 months ended July 31, 1997. The rising tide, which
pushed the widely followed Dow Jones Industrial Average from one new high to
another, was driven by rosy economic growth and low inflation.
Large-capitalization stocks were steady performers throughout the period, with
small- and medium-cap stocks joining the rally by mid spring.

Putnam Vista Fund, which focuses primarily on medium-size growth companies,
consequently lagged behind the benchmark indexes for much of the year and yet
delivered strong absolute results for the full year: class A shares were up
36.25% at net asset value (28.39% at public offering price) for this fiscal
year. Complete performance information, including results for other share
classes, appears on pages 9 through 10.

* RECORD-SETTING PACE ON WALL STREET

The fund's fiscal year encapsulated one of the most astounding bull markets in
history. The Dow passed the milestone 6000 mark in October and topped 7000 in
February. Incredibly, five months later -- just before the close of the fund's
fiscal year -- this market indicator crossed the 8000 barrier. In addition,
the technology-laden NASDAQ Composite Index surged during the last quarter of
fiscal '97. Stock investors were clearly pleased with the breadth and pace of
economic growth.

Two factors that fueled the rise in stock prices were corporate profits and
low inflation, both of which consistently exceeded investors' expectations
over the period. In addition, a forward-looking Federal Reserve Board, with
Alan Greenspan at its helm, fostered steady growth and remains vigilant for
warning signs of inflation. The Fed's increase in short-term interest rates in
March was a temporary bump; investors acknowledged that this near-term
adjustment was necessary to keep the economy robust over the longer term. The
stock market's rally was further strengthened by Washington's summer
deficit-reduction package, which included a decrease in the capital gains tax.

Given such a rapid advance in such a short time, Chairman Greenspan has warned
about "excessive optimism" and "irrational exuberance" on several occasions.
Such advice is worth heeding, and as always, we ask our shareholders to temper
their expectations.

* MARKET'S ADVANCE LED BY LARGE-CAPITALIZATION STOCKS; MID-CAPS JOIN RALLY IN
LATE SPRING

For the first three quarters of the fiscal year, large-cap stocks outperformed
their small and medium-size counterparts. The economy's strong performance in
late 1996 and early 1997, while favorable for corporate profits, raised
concerns over inflation and the possibility of interest-rate increases by the
Fed -- an environment that encouraged investors to seek the security of
large-company stocks. By late spring, however, with the outlook for inflation
and growth moderating, investor enthusiasm for smaller companies began to
return, and prices rebounded from their April lows.

We remain optimistic about medium-size companies for several reasons. First,
mid-cap stocks, technology stocks in particular, are dependent to a greater
extent on product cycles and the desire on the part of their customers to
increase productivity. Second, the federal budget legislation included a
reduction in the capital gains tax from 28% to 20%, thus improving the
after-tax return for growth stocks. Finally, having survived their smaller,
start-up phase, many medium-size companies are poised for rapid growth. Your 
fund's commitment to diversification across many sectors, we believe, holds 
the key to uncovering the companies with above-average growth potential 
and the promise of becoming tomorrow's large-cap leaders.

* TECHNOLOGY HOLDINGS STRENGTHEN LATE IN PERIOD

Although volatility throughout the technology industry continued well into the
second half of the fiscal year, two sectors -- semiconductors and computer
software -- made notable contributions to the fund's performance.
Semiconductor stocks, such as Analog Devices, which was sold at a profit
before the year's end, performed better than expected as new orders picked up
and a feared correction in the industry failed to materialize.

Many of the fund's computer software holdings are geared toward the business
community with an emphasis on products that increase productivity. Peoplesoft,
Inc. is one holding that is leading the transition from mainframe systems to
new client server-based systems.

While a heavy presence of technology stocks benefited the fund, some holdings
proved disappointing. For example, Picturetel Corp. (video conferencing)
failed to meet our growth targets when product deliveries fell behind
schedule. In addition, the networking equipment industry fell short of
expectations. Spending for infrastructure didn't materialize as anticipated,
resulting in subpar performance for several holdings.

The year 2000 issue -- or Y2K -- continues to present some of the most dynamic
opportunities within the technology and business services industries.
Companies around the world are struggling to prevent the loss of essential
data, applications, and even hardware within systems that are not equipped to
digest dates after December 31, 1999. Each company faces a unique set of
challenges that must be addressed from a business as well as a technological
viewpoint.

In most cases, however, the response is to reprogram existing systems, to
replace outdated software and hardware, or to customize a solution that
combines both approaches. Viasoft, Inc., a fund holding, is at the forefront
of this once-in-a-millennium opportunity. While these holdings, along with
others discussed in this report, were viewed favorably at the end of the
fiscal period, all portfolio holdings are subject to review and adjustment in
accordance with the fund's investment strategy and may vary in the future.

* SOLID ECONOMIC GROWTH BENEFITS CONSUMER-RELATED INDUSTRIES

Consumer cyclical stocks, which include companies whose profits are tied to
the strength of the economy, were big winners during the year. Specialty
retailing stocks have enjoyed a steady comeback with Bed, Bath & Beyond (which
we have since sold at a profit), Borders Group, and Pier 1 Imports among the
portfolio's better performers. Higher employment and consumer confidence
levels coupled with well-managed inventory levels have led to improving profit
margins for stores like Consolidated Stores Corp. and The TJX Cos., Inc. --
the parent company of TJ Maxx.

Food and drug retailers have done well. Supermarkets are lowering their cost
of operations by utilizing new technologies that lead to more efficient
inventory management and stronger merchandising. As a result of their
partnerships with health maintenance organization (HMOs) that direct patients
to preferred vendors, drugstore chains are prospering from an increased flow
of customers. Coupled with improved merchandising, profitability is increasing
for holdings such as Rite Aid Stores.

In the consumer nondurable area, radio broadcasting is benefiting from the
passage of the Telecommunications Act of 1996, which allowed a single operator
to own several stations in a large metropolitan area. As a result, radio
operators are spreading the cost of programming across multiple stations to
reduce expenses. Clear Channel Communications, Inc. and Evergreen Media Corp.
have been steady performers, gaining market share and increasing advertising
revenues.

Finally, a presence in several subsectors within the health-care industry --
HMOs, acute services, and elderly care -- contributed to fund performance.
Oxford Health Plans, Inc. is a well-managed HMO gaining a larger market share
in New York by successfully targeting the growing elderly population. As
hospitals rein in costs by reducing hospital stays, Healthsouth Corp. is
capturing an increasing share of the outpatient rehabilitation health-care
market.

* MIDSIZE COMPANIES MAY HAVE THEIR DAY

Just following the close of the fiscal period, investor sentiment for large,
blue-chip stocks soured in the wake of a series of disappointing earnings
reports. As investors re-evaluate their large-cap holdings, we believe they
may turn to midsize companies as their earnings growth rates improve. Having
survived their smaller, start-up phase, medium-sized companies are poised for
rapid growth. Your fund's commitment to diversification across many sectors,
we believe, holds the key to uncovering the companies with above market growth
potential and the promise of becoming tomorrow's large-cap leaders.

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 7/31/97, there is no guarantee the fund will continue to hold
these securities in the future. The fund invests all or a portion of its
assets in small to medium-size companies. Such investments increase the risk
of greater price fluctuations.

Returns for class A and class M shares reflect the current maximum initial
sales charges of 5.75% for class A shares and 3.50% for class M shares.
One-, five-, and ten-year (when available) and life-of-fund returns for
class B shares reflect the applicable contingent deferred sales charges
(CDSC), which is 5% in the first year, declines each year 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 costs
applicable to such shares. All returns assume reinvestment of
distributions at NAV and represent past performance; they do not guarantee
future results. 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.

Performance data represent past results, do not reflect future

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 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 maximum 5.75% 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.

COMPARATIVE BENCHMARKS

Standard & Poor's Midcap 400 Index is an unmanaged, market-weighted list
of 400 medium-sized companies, each affecting the index in proportion to
market value. The index assumes reinvestment of all distributions and does
not take into account brokerage commissions and other costs. The fund's
portfolio contains securities that do not match those in the index, and
performance of the fund will differ. It is not possible to invest
directly in an index.

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



Report of independent accountants

To the Trustees and Shareholders of
Putnam Vista 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 Vista Fund
(the "fund") at July 31, 1997, 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, 1997 by correspondence with the
custodian and the application of alternative auditing procedures where
investments purchased were not received by the custodian, provide a reasonable
basis for the opinion expressed above.

Notes to financial statements
July 31, 1997

Note 1
Significant accounting policies

Putnam Vista 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
selected for above-average growth potential and that involve certain risks.
The fund may also trade securities for short-term profits.

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 are 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 shares, class B shares and class M shares, but do not bear
a distribution fee. Class Y shares are sold to defined contribution plans that
invest at least $250 million in a combination of Putnam funds and other
accounts managed by affiliates of Putnam Management.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears certain 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 that fund were liquidated. In addition, the Trustees declare separate
dividends on each class of shares.

The following is a summary of significant accounting policies 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 Investment
Management, Inc. ("Putnam Management"), the fund's Manager, a wholly-owned
subsidiary of Putnam Investments, 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. 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 except that certain dividends from foreign
securities are recorded as soon as the fund is informed of the ex-dividend
date.

E) 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. 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.

F) 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. This difference includes treatment
of net operating losses, 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, 1997, the fund
reclassified $13,208,411 to decrease undistributed net investment losses and
$13,213,082 to decrease paid-in-capital, with an increase to accumulated net
realized gains on investments of $4,671. 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: 0.65% of the first $500 million of
average net assets, 0.55% of the next $500 million, 0.50% of the next $500
million, 0.45% of the next $5 billion, 0.425% of the next $5 billion, 0.405%
of the next $5 billion, 0.39% of the next $5 billion and 0.38% thereafter.
Prior to November 20, 1996, any amount over $1.5 billion was based on 0.45%.

The fund reimburses Putnam Management 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 wholly-owned 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, 1997, fund expenses were reduced by $1,047,892
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.

Trustees of the fund receive an annual Trustees fee of $2,750 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 "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 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, 1997, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $2,174,005 and $88,240 from the sale
of class A and class M shares, respectively and $1,074,003 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, 1997, Putnam Mutual Funds Corp., acting as underwriter
received $40,749 on class A redemptions.

Note 3
Purchase and sales of securities

During the year ended July 31, 1997, purchases and sales of investment
securities other than short-term investments aggregated $3,773,429,182 and
$2,286,925,261, 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

At July 31, 1997, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:
