EIGHT BASIC PRINCIPLES FOR SUCCESSFUL MUTUAL FUND INVESTING

These  common-sense rules are followed by many successful  investors.  They make
sense for beginners,  too. If you have a question on these principles,  or would
like to discuss them with us, please contact us at 1-800-368-3863. We're here 24
hours a day, seven days a week to take your call.

- --------------------------------------------------------------------------------
[PICTURE OF FOLDER LABELED INVESTMENTS]

1. HAVE A PLAN.  Even a simple plan can help you take control of your  financial
future. Review your plan once a year, or if your circumstances change.

- --------------------------------------------------------------------------------
[PICTURE OF CLOCK]

2. START  INVESTING AS SOON AS POSSIBLE.  Make time a valuable  ally. Let it put
the power of compounding to work for you, while helping to reduce your potential
investment risk.

- --------------------------------------------------------------------------------
[PICTURE OF PIE CHART OF ASSET DIVERSIFICATION]

3. DIVERSIFY YOUR  PORTFOLIO.  By investing in different asset classes - stocks,
bonds,  and cash - you help  protect  against  poor  performance  in one type of
investment  while  including  investments  most likely to help you achieve  your
important goals.

- --------------------------------------------------------------------------------
[PICTURE OF MEMO REMINDER TO INVEST]

4. INVEST REGULARLY.  Investing is a process, not a one-time event. By investing
regularly  over the long  term,  you  reduce  the  impact of  short-term  market
gyrations,  and you attend to your long-term plan before you're tempted to spend
those assets on short-term needs.

- --------------------------------------------------------------------------------
[PICTURE OF GRAPH SLOPING UPWARD]

5. MAINTAIN A LONG-TERM PERSPECTIVE.  For most individuals,  the best discipline
is staying invested as market conditions change. Reactive,  emotional investment
decisions are all too often a source of regret - and of principal loss.

- --------------------------------------------------------------------------------
[PICTURE OF PIE CHART OF ASSET DIVERSIFICATION EMPHASIZING STOCKS]

6. CONSIDER STOCKS TO HELP ACHIEVE MAJOR LONG-TERM GOALS. Over time, stocks have
provided the more powerful  returns needed to help the value of your investments
stay well ahead of inflation.

- --------------------------------------------------------------------------------
[PICTURE OF DOLLAR SIGN]

7. KEEP A COMFORTABLE  AMOUNT OF CASH IN YOUR PORTFOLIO.  To meet current needs,
including  emergencies,  use a money  market  fund or a bank  account - not your
long-term investment assets.

- --------------------------------------------------------------------------------
[PICTURE OF MAGNIFYING GLASS]

8. KNOW WHAT YOU'RE BUYING.  Make sure you  understand  the potential  risks and
rewards  associated  with  each of  your  investments.  Ask  questions...request
information...make  up your own mind.  And choose a fund  company that helps you
make informed investment decisions.

THE STRONG VALUE FUND


WE'VE BEEN BOOSTING OUR POSITION IN FINANCIALS, GIVING US GREATER EXPOSURE TO AN
INDUSTRY THAT IS POSITIONED TO BENEFIT FROM THE CURRENT ECONOMIC CLIMATE.

The Strong Value Fund seeks capital growth. The Fund invests primarily in equity
securities,  seeking  through  fundamental  analysis those companies whose share
prices do not fully  reflect  their value,  or  companies  that are selling at a
discount  relative to their  historical  price or to other companies in the same
industry.

To identify  value,  our research team looks for  catalysts--such  as management
changes,  corporate  restructurings,   or  underlying  shifts  in  a  particular
industry--that  we  believe  may signal a  resurgence  in the  stock's  price or
earnings.

The Fund may  invest in  companies  of any  size,  but it  currently  emphasizes
medium- and large-size firms.

LARGE GROWTH STOCKS CONTINUE TO LEAD THE WAY
The markets  made a record  upward  drive over the past six months,  interrupted
only by a hiccup in late  March and early  April when  the  Fed's  interest-rate
hike  temporarily  raised fears of rising  inflation and interest rates.  Growth
stocks--particularly  the largest,  priciest  companies--  dominated the market,
while smaller companies and value stocks of all sizes lagged considerably.

This market clearly presented  challenges given our investment  discipline.  For
the six months ended June 30, the Fund returned  12.48%,  while the Russell 1000
Value  Index  returned  17.68%.*(1)  It has been  difficult  to find  compelling
values,  and we have added few new issues in recent  months.  When we have found
stocks at attractive  values,  they have tended to be among  companies  that are
restructuring  or going through  management  changes.  These  include  Providian
Financial and ADT (which recently merged with Tyco International).

THE CURRENT ENVIRONMENT
Trends driving the economy and the market include  rising  productivity,  global
competition, strong corporate profits, and low inflation. Technology has changed
information flows for companies.  Information regarding sales, inventory levels,
and  capacity   changes--whether   on  a  global  or  local  level--are  relayed
instantaneously,  helping  manufacturers and retailers to avoid overstocking and
shortages. Even though the Fund does not generally invest directly in technology
stocks  (in an  effort  to manage  volatility),  we do look for  firms  that can
benefit from technological innovations.

Global competition,  combined with productivity and technology gains, has helped
to maintain  low  inflation.  Also giving a boost to the  environment  for stock
investing is the  imbalance  between the demand and supply of equities.  Further
supporting  the  market  is  a  stable   political   environment.   The  Clinton
administration  and Congress have been fiscally  prudent,  giving comfort to the
capital markets.

HOW THE ENVIRONMENT AFFECTS OUR CHOICES
In  this  economy  of  low  inflation,  low  unemployment,   and  high  consumer
confidence,  consumer spending has risen only moderately.  Following this trend,
we have been slowly de-emphasizing the consumer sector,  particularly retailers.
In addition,  we've been boosting our position in financials,  giving us greater
exposure to an industry that is positioned to benefit from the current  economic
climate.

CONTINUING WITH OUR VALUE-STOCK DISCIPLINE
Our discipline is to buy stocks near the low end of their valuation  range,  and
sell them as they reach the upper end.  Several  stocks,  including TIG Holdings
and Kimberly  Clark,  were sold out of the Fund for  precisely  this reason.  In
addition, we sell stocks that fail to meet our expectations for improvement, and
thus no longer represent a good value. Although our approach cannot insulate the
Fund  entirely  from any  downturns,  it does help the Fund to avoid some of the
market's widest swings.

Our  investment  approach  has kept us from  fully  participating  in the recent
large-cap  growth-driven  bull market. In sticking with our investment  criteria
and price discipline,  however, we're maintaining a strategy that we believe can
deliver strong returns over the long term while managing risk effectively.

OUTLOOK
We do not  anticipate  much  change in the near term  environment  which,  while
positive,  can  make it  difficult  to find  stocks  at  attractive  valuations.
Investors' optimistic assumptions have largely been factored into stock prices.

Nonetheless,  with much of the market at near record  levels,  there's plenty of
room for downside  movement,  whether the cause be a series of earnings  reports
below  expectations  or some other negative piece of short-term  news. As in the
past,  we would  view such  volatility  as an  opportunity  to buy  high-quality
companies whose prices have fallen to attractive levels.

Thank you for your  investment  in the Strong  Value Fund.  We  appreciate  your
confidence, and look forward to helping you pursue your long-term growth goals.

Sincerely,

THE STRONG OPPORTUNITY FUND


THIS FUND IS  POSITIONED  TO DO WELL WHEN  SOFTNESS  HITS THE  MARKET'S  CURRENT
LEADERS, AND CONTINUE TO KEEP PACE IN A HEALTHY MARKET ENVIRONMENT.

The Strong  Opportunity Fund seeks capital growth. The Fund invests at least 70%
of its net assets in equity  securities,  emphasizing  small  companies that the
Fund's Advisor believes are under-researched and attractively valued.

For the six months  ended June 30, the market was very  strong,  but it was also
narrow,  with  the bulk of the S&P  500's  returns  coming  from 10 to 12 of its
largest  stocks.  Most of the market  posted  modest  returns,  and even losses.
Nonetheless,  we were able to  deliver  a return  of 9.60%  for the six  months,
compared with the S&P 500's 20.61% return and the S&P MidCap 400's 12.99%.*(1)

====================================================

AN UNUSUAL MARKET

The  market  has been an  aberration,  in that  it's  been  driven by just a few
stocks.  Momentum has played a much larger role in many stocks' performance than
their underlying fundamentals. Investors in this narrow group of stocks could be
paying more than what the companies are worth--and that's different from what we
try to do with the Opportunity Fund.

Our private  value  approach to investing  means that we look at stocks as if we
were considering  buying the entire  company--and then compare the price we'd be
willing to pay with the current stock price. The current market,  marked by high
demand for equity securities in general,  makes it harder to find underfollowed,
undervalued  stocks  as you  move  up  the  market-capitalization  ladder.  That
presents a challenge for the Opportunity  Fund,  which focuses on mid-cap stocks
as well as smaller companies.

SPECIFIC AREAS OF FOCUS HAVE WORKED WELL
Although the momentum for larger companies predominated for most of the past six
months, there has been some broadening out in the market recently.  For example,
small-cap stocks  experienced some strength in May. Much of the small-cap market
had been so beaten down that they  enjoyed a rebound.  The  portfolio  benefited
from this rally because few of our smaller  stocks had been  battered--so  their
increases in the May upturn weren't offset by an earlier decline.

Our significant overweighting in media stocks has begun to pay off. Our picks in
this sector did well in May and June, on the heels of  Microsoft's  announcement
that it would  invest $1 billion in cable  television  operations.  The position
we've built up in foreign stocks has also performed well.

We have built a long  record of success  based on a  discipline  of looking  for
opportunities in underfollowed  sectors and buying stocks cheaply. This has been
a good  strategy over the long term,  but of late it has  presented  opportunity
costs  as the  market's  attention  has  fled  toward  the  largest,  best-known
companies.  We're not going to change a proven  strategy  because  of a narrowly
focused market, however. As the correction in late March and early April showed,
markets can change  quickly.  This Fund is  positioned  to do well when softness
hits the market's current leaders, and continue to keep pace in a healthy market
environment.

OUTLOOK
Currently,  the market is enjoying the best of all worlds.  The domestic economy
is strong,  inflation is low,  and  favorable  conditions  reign in most foreign
markets.  With such a positive  environment,  if the market were ever to be at a
high, it would be now. Investors really shouldn't focus on whether the market is
too high; rather, they should think about whether the world will remain as solid
as it has been recently.

Our strategy  should  serve  investors  especially  well if we  experience  more
challenging  markets in the coming months. The portfolio has been assembled with
a strong eye toward  valuations,  and it focuses on quiet or ignored  sectors of
the market. A market downturn would likely punish momentum-driven  stocks, while
we would expect stocks out of the limelight to fare better.

We're  renewing our focus on  high-quality  companies.  At times,  this may mean
paying somewhat more for a stock than we might have been willing to in the past.
This is not a shift in strategy.  It's a refinement that is designed to help the
Fund  prosper  in the  current  environment.  When few  stocks  are  cheap on an
absolute  basis,  it's necessary to look for companies at reasonable  valuations
with strong management teams and competitive positions.

Thank you for your investment in the Strong Opportunity Fund. We look forward to
helping you pursue your important financial goals.

Sincerely,

THE STRONG MID CAP FUND


WE  BELIEVE  THAT  THE  MID-CAPITALIZATION  SECTOR  OF THE  MARKETPLACE  HAS THE
POTENTIAL TO PROVIDE  INVESTORS WITH SUPERIOR  RETURNS OVER TIME. 

The Strong Mid Cap Fund seeks  capital  growth.  The Fund  invests  primarily in
stocks of companies that have midsize market capitalizations. While these stocks
can be very volatile  over short time periods,  they have the potential to amply
reward investors over time.

In  general,  the Fund tends to invest in  high-growth  companies,  rather  than
low-priced  value-style stocks. Growth companies typically offer the benefits of
talented  management,  strong  balance  sheets,  healthy sales and  accelerating
earnings growth.

====================================================

MIDSIZE  STOCKS HAD A DIFFICULT  FIRST HALF 

The  Fund's  underperformance  in the  first  half of the year  relative  to its
benchmark,   the  S&P  MidCap  400,   reflects  its  growth  style.  The  entire
mid-capitalization  sector of the market-place  experienced a  severe correction
through  the first  four  months of 1997,  driven by fears  that  stronger  than
expected  economic growth would lead to rising inflation and interest rates. The
decline among the higher-growth,  higher-priced  companies in the mid-cap market
during  these  first four  months was much  deeper  than the  decline in the S&P
MidCap  400.  The  technology  sector,  in which the Fund is  overweighted,  was
particularly  hard hit.  As a  result,  the  Fund's  return of 1.04% for the six
months lagged the S&P MidCap 400's gain of 12.99%.*(1)

The  breadth  and  depth of the  decline  in mid caps in the first  four  months
approached  levels last seen in the summer and fall of 1990. The 1990 correction
signaled the end of an extended period of  underperformance  for mid-cap stocks.
The  recent  decline  appears  similar--we  believe  it  signaled  the  end of a
correction that began in the summer of 1996. Small-cap stocks performed strongly
in May and June,  reversing much of the declines from January through April. For
the year to date, however, they still lag the S&P 500 by a wide margin.

By the end of April,  valuations  in  mid-size,  high  growth  stocks had become
extraordinarily  compelling.  Many stocks were cheaper relative to their rate of
earnings growth than they had been since 1990. We used the buying opportunity to
further  improve  the  quality  of the  portfolio.  We  remain  overweighted  in
technology  and health care,  and  underweighted  in  financials,  utilities and
energy.  These weightings reflect our bias toward companies that have strong and
consistent earnings growth.


THE CASE FOR MID CAPS
We  believe  that  the  mid-capitalization  sector  of the  marketplace  has the
potential to provide  investors  with  superior  returns over time.  This belief
rests on several premises that are structural as well as cyclical:

o    The global  landscape of the 1990s is one of rapid  change.  The removal of
     tariffs as  barriers to trade and the rise of new  economic  powers such as
     China  imply  that   successful   companies  in  the  future  will  require
     flexibility,  agility,  and innovation to capitalize on what seems to be an
     ever more quickly changing world.

     This changing landscape plays to the strengths of mid-size companies,  many
     of  which  have   developed  new  business   models   involving   strategic
     relationships  around the world. These models capitalize on the flexibility
     and agility  inherent in mid-size  companies so that their  ability to seek
     out  opportunities  in advance of their larger brethren become  significant
     competitive  advantages,  while their small  size,  in today's  free market
     environment, is no longer a disadvantage.

o    Mid-capitalization  stocks are a relatively  new  phenomenon  as a separate
     asset class.  Currently,  they  represent  less than 10% of the U.S.  stock
     market  in  terms  of  capitalization.  It is an asset  class  that  offers
     attractive  risk/return  characteristics.  Companies  of  this  size  offer
     significantly more growth potential than larger-capitalization  stocks, but
     have more mature and consistent  business models than  small-capitalization
     stocks. Historically, they move with smaller-capitalization stocks' cycles,
     and  over  long  periods  of  time,  they  have  delivered  returns  almost
     comparable  with that of the small-cap  sector with less risk. In an era of
     greater overall  volatility and concern about risk,  these  characteristics
     may make them ideal  investments  for those  seeking  greater  returns than
     larger-cap  stocks but a lower risk profile  than  smaller-cap  stocks.  We
     believe  that  as the  characteristics  of  this  asset  class  are  better
     understood, it will attract more investor attention.

<PAGE>
o    The potential  reward profile of this sector of the market  continues to be
     outstanding.  The  valuations  of  mid-size  companies  are below  those of
     large-cap stocks,  but the mid-cap sector is expected to have higher growth
     rates over the next 12 months.

As we approach the beginning of the next century, we are truly in the midst of a
global,  structural  transformation  that has  tremendous  cultural,  political,
social and economic  implications.  New  technological and economic leaders will
emerge.  Our strategy seeks to capture these trends and identify these companies
before the market fully uncovers them.

We believe that mid-size growth companies are  exceptionally  well positioned to
take  advantage of these major  changes.  We also  believe they will  positively
surprise  investors by showing  continued  improvement in profitability  and raw
earnings power for the foreseeable future.  Clearly, those companies that are on
the cutting  edge of the change  curve will lead the way. We believe the Fund is
well positioned to take advantage of these opportunities.

Thank you for your  investment in the Strong Mid Cap Fund.  We  appreciate  your
support and look forward to serving your investment needs in the future.

Sincerely,

THE STRONG COMMON STOCK FUND


FOR THE SIX MONTHS  ENDED JUNE 30, THE MARKET WAS VERY  STRONG,  BUT IT WAS ALSO
NARROW.

The Strong Common Stock Fund seeks capital growth. The Fund invests at least 80%
of its net assets in equity  securities,  emphasizing  small  companies that the
Fund's Advisor believes are under-researched and attractively valued.

For the six months  ended June 30, the market was very  strong,  but it was also
narrow,  with the bulk of the S&P 500's returns coming from just 10 to 12 of its
largest  stocks.  Most of the market  posted  modest  returns,  and even losses.
Nonetheless, the Fund was able to deliver a return of 14.93% for the six months.
That  figure is well ahead of our  benchmark,  the  Russell  2000  Index,  which
returned 10.20% for the same period.*(1)

====================================================

AN UNUSUAL MARKET
The  market  has been an  aberration,  in that  it's  been  driven by just a few
stocks. Momentum has played a larger role in many stocks' performance than their
underlying  fundamentals.  Investors  in this  narrow  group of stocks  could be
paying more than the companies are worth--and  that's different from what we try
to do with the Common Stock Fund.

Our private  value  approach to investing  means that we look at stocks as if we
were considering  buying the entire  company--and then compare the price we'd be
willing  to pay  with  the  current  stock  price.  Finding  stocks  that  trade
significantly  below this private  value is easier  among the smaller  companies
that are this Fund's focus.

SPECIFIC AREAS OF FOCUS HAVE WORKED WELL
Although the momentum for larger companies predominated for most of the past six
months,  there has been some  broadening  out recently.  For example,  small-cap
stocks  experienced  some strength in May. Much of the small-cap market had been
so beaten  down that it enjoyed a rebound.  The  portfolio  benefited  from this
rally because few of our smaller stocks had been battered--so their increases in
May weren't offset by an earlier decline.

Our significant overweighting in media stocks has begun to pay off. Our picks in
this sector did well in May and June, on the heels of  Microsoft's  announcement
that it would invest $1 billion in cable television operations.

The position  we've built up in foreign stocks has also  performed  well.  We're
pleased with our small position in Latin American companies,  which seem to have
good prospects going forward, along with our Canadian stocks.

We have built a long  record of success  based on a  discipline  of looking  for
opportunities in underfollowed  sectors and buying stocks cheaply. This has been
a good  strategy over the long term,  but of late it has  presented  opportunity
costs  as the  market's  attention  has  fled  toward  the  largest,  best-known
companies. We're not going to change a proven strategy because of unusual market
conditions,  however.  As the  correction  in late March and early April showed,
markets can change  quickly.  This Fund is  positioned  to do well when softness
hits the  market's  current  leaders,  and to continue to keep pace in a healthy
market environment.

OUTLOOK
Currently,  the market is enjoying the best of all worlds.  The domestic economy
is strong,  inflation is low,  and  favorable  conditions  reign in most foreign
markets.  With such a positive  environment,  if the market were ever to be at a
high, it would be now. Investors really shouldn't focus on whether the market is
too high; rather, they should think about whether the world will remain as solid
as it has been recently.

Our strategy  should  serve  investors  especially  well if we  experience  more
challenging  conditions in the coming  months.  The portfolio has been assembled
with a strong eye toward valuations,  and it focuses on quiet or ignored sectors
of the market.  A market  downturn would likely punish  momentum-driven  stocks,
while we would expect stocks out of the limelight to fare better.

We're  renewing our focus on  high-quality  companies.  At times,  this may mean
paying somewhat more for a stock than we might have been willing to in the past.
This is not a shift in strategy.  It's a refinement that is designed to help the
Fund  prosper  in the  current  environment.  When few  stocks  are  cheap on an
absolute  basis,  it's necessary to look for companies at reasonable  valuations
with strong management teams and competitive positions.

We welcome our new  shareholders who joined us when the Fund briefly reopened to
IRA  investors  this  spring.  We look  forward to helping  you,  as well as our
longtime  investors,  to  pursue  your  financial  goals.  Thank  you  for  your
investment in the Strong Common Stock Fund.

A NARROW, BUT BROADENING MARKET
The past six months have been challenging for Funds not solely tied to large-cap
stocks.  That's  because the market has been driven  primarily  by a rush to the
very  largest  companies  in the  market.  Even the S&P 500,  itself a  somewhat
exclusive group of 500 of the largest companies, has seen its performance driven
by just a handful of its biggest stocks.  Thus the benchmark has become less and
less reflective of what's happening in the broader market.*

What's very positive is that,  after some time,  we're finally seeing the market
move more  toward  the style of  investing  that has  allowed  this Fund to post
strong  returns  in the recent  past.  Perhaps  the  clearest  evidence  of this
broadening of the market's strength is our return for the second quarter of this
year, a healthy 17.70%.  That slightly exceeds the S&P 500's return for the same
period.  Given  that  our  return  for the six  months  ended  June 30 is  9.66%
(compared  with the S&P's  20.61%),  that  signifies a real  improvement  in the
broader market-- and in the type of stocks we pick.(1)

WHAT'S DRIVING THE FUND
Taking a look at some of the stocks that have driven our return to form say much
about the criteria we use as we invest.

o    Pharmaceuticals  maker  Warner-Lambert,  currently our largest holding, has
     been on a tear with the early  success of two new drugs,  Lipitor (for high
     blood  cholesterol)  and Rezulin (an oral diabetes  medication).  These are
     projected to become some of the fastest growing new drugs ever. We selected
     Warner-Lambert  not only for its  strong  fundamentals  and its  reasonable
     valuation,  but also for the strength and  improvement  we perceived in its
     competitive  position.  In addition to these two new products,  the company
     has  several  other  new  drugs  in the  pipeline,  as well as an  array of
     successful, established brands.

     Our investment in Warner-Lambert  also reflects one of the recurring themes
     of this Fund:  investing in health-care  related companies,  which stand to
     benefit  from the aging U.S.  population.  We continue to  overweight  this
     sector.

o    Kohl's,  a department  store chain,  is a smaller but still important stock
     for the Fund.  Based in our back yard in Menomonee  Falls,  Kohl's has been
     steadily  picking up steam.  Its  expansion in the  Washington-Philadelphia
     corridor has been successful,  and its comparable-store  sales have enjoyed
     double-digit growth. Our focus on the company's financial strength, and our
     direct,  on-site research,  helped us to select this stock at an attractive
     valuation.

o    Oil  services  and  drilling  has  been an  important  sector.  We've  been
     investing with this theme for the past few years, and it appears to us that
     it still has a couple of years left to run.  Driving  this  sector has been
     new  exploration;  as this activity has paid off with new oil reserves,  it
     has added to these companies' earnings power.

o    We've also enjoyed  success as the market has favored other longtime themes
     of ours, including technology and financials.

We've  always asked  investors  to consider  the Strong  Growth Fund a long-term
investment,  and that's how we'll  continue to invest  ourselves.  We will stick
with what we consider to be the best strategy for the long  term--looking  among
small-,  medium-,  and large-cap  companies for the  highest-quality  firms with
reasonable  valuations in sectors that are poised for growth. We believe we have
positioned  the portfolio to benefit from the broadening of the bull market that
has begun, and that we anticipate will continue.

We thank you for your  investment  with the Strong Growth Fund,  and  appreciate
your  continued  support.  We look forward to helping you pursue your  important
financial goals for years to come.

Sincerely,

THE STRONG DISCOVERY FUND


OVERALL, THE RECENT MARKET ENVIRONMENT REMINDS US OF 1990 AND 1991.

The Strong Discovery Fund seeks to provide investors with capital growth, a goal
we  pursue  by  investing  in a  diversified  portfolio  of  small-,  mid-,  and
larger-cap stocks. Our investment  approach combines  number-crunching  analysis
with direct research,  including  on-site visits.  Through frequent  discussions
with  management,  suppliers,  customers  and  competitors,  we  believe  we can
identify  vital aspects of companies that aren't  reflected in their  historical
financial statements--or their stock prices.

========================================
          ASSET ALLOCATION

The Fund's asset allocation does not

========================================

The Discovery  Fund's  portfolio  measures up well under the key criteria we use
when  selecting  stocks--good   businesses,   good  managements  and  attractive
valuations.  In general,  we are pleased with the quality and performance of the
companies  in the  portfolio.  With few  exceptions,  they have been  meeting or
exceeding  their profit  targets.  We are also pleased with the valuation of the
portfolio, especially compared with the high valuations being accorded the large
companies that dominate the S&P 500 Index. As the following  table  illustrates,
the  Fund's  average  valuation--as  measured  by its  price/earnings  ratio--is
slightly  below the S&P 500's.  Based on our  analysis of the  companies  in the
portfolio, we estimate the portfolio's earnings growth potential to be more than
three times that of the S&P 500. By  concentrating  on companies  with  superior
growth potential, we seek to produce superior investment results over time.

                           P/E RATIO           ESTIMATED
FUND                      (1998 EARNINGS)      EARNINGS GROWTH(1)
- --------------------------------------------------------------------------------
Strong Discovery Fund      17.9x                 24.3%
S&P 500 Index              18.8x                  7.8%

In our investment  process,  we make  forward-looking  decisions.  Our job is to
position  the  portfolio  for what we expect to happen,  not to chase  after the
market  sectors or stocks  that have  recently  performed  best.  We continue to
believe that small- and  medium-size  growth  stocks offer the most  opportunity
looking forward. In hindsight, however, our decision to emphasize this group was
premature.  As a  result,  our 4.01%  total  return  for the first  half of 1997
trailed  the  20.61%  return  of the S&P 500 and the  10.16%  return of our peer
group,  the Lipper  Capital  Appreciation  Funds  Index.  Including  this year's
performance through June, the Discovery Fund's average annual total return since
its  12-31-87  inception  is 16.32%,  which  keeps us ahead of our peer  group's
average  annual return of 14.82%.  But it puts us below the S&P's average annual
gain  since  our  inception--  a  figure  we  have  historically   surpassed--of
17.83%.*(2)

<PAGE>
Overall, the recent market environment reminds us of 1990 and 1991. Then as now,
investors  moved  toward  indexation--trying  to  replicate  the S&P 500 without
regard for the merits of the  individual  companies or their prices.  Eventually
this cycle came to an end,  creating an  opportunity  for  investors  willing to
consider stocks outside the S&P 500's largest. We were able to capitalize on the
situation then, and posted a 67.6% gain for 1991,  versus a 30.5% return for the
S&P 500. We have  currently  positioned  the Fund to benefit  from what may be a
similar scenario.

Thank you for your  investment in the Strong  Discovery Fund. We appreciate your
support, and are committed to earning it.

Sincerely,

THE STRONG SMALL CAP FUND


BY THE END OF APRIL,  VALUATIONS  IN  SMALLER,  HIGH  GROWTH  STOCKS  HAD BECOME
EXTRAORDINARILY COMPELLING.

The Strong Small Cap Fund seeks capital  growth.  The Fund invests  primarily in
stocks of companies that have small market  capitalizations.  While these stocks
can be very volatile  over short time periods,  they have the potential to amply
reward investors over time.

In  general,  the Fund  tends to invest in  high-growth  companies  rather  than
low-priced  value-style stocks. Growth companies typically offer the benefits of
talented  management,  strong balance sheets,  healthy sales,  and  accelerating
earnings growth.

SMALL COMPANY STOCKS HAD A DIFFICULT FIRST HALF
The  Fund's  underperformance  in the  first  half of the year  relative  to its
benchmark,  the  Russell  2000,  reflects  its growth  style.  The entire  small
capitalization sector of the marketplace experienced a severe correction through
the first four  months of 1997,  driven by fears  that  stronger  than  expected
economic growth would lead to rising  inflation and interest rates.  The decline
in the higher-growth,  higher-price  sector of the small-cap market during these
first four months was much deeper  than the  decline in the  Russell  2000.  The
technology sector, in which the Fund is overweighted, was particularly hard hit.
As a  result,  the  Fund's  returns  for the six  months of  -8.85%  lagged  the
Russell's 10.20% gain.*(1)

The  breadth  and depth of the  decline in small  caps in the first four  months
approached  levels last seen in the summer and fall of 1990. The 1990 correction
signaled the end of an extended period of underperformance for small-cap stocks.
The  recent  decline  appears  similar--we  believe  it  signaled  the  end of a
correction that began in the summer of 1996. Small cap stocks performed strongly
in May and June,  reversing much of the declines from January through April. For
the year to date, however, they still lag the S&P 500 by a wide margin.

By the end of April,  valuations  in  smaller,  high  growth  stocks  had become
extraordinarily  compelling.  Many stocks were cheaper relative to their rate of
earnings growth than they had been since 1990. We used the buying opportunity to
further  improve  the  quality  of the  portfolio.  We  remain  overweighted  in
technology and health care, and  underweighted  in  financials,  utilities,  and
energy.  These weightings reflect our bias toward companies that have strong and
consistent  earnings growth.  In choosing stocks,  we concentrated on those that
fit our highly defined investment criteria:

o    We build  our  portfolio  based  on  broad  secular  trends  affecting  the
     economic,   societal,   and  demographic   landscape.   These   overarching
     themes--which help the portfolio reflect where the world is headed--include
     the  aging of  America,  the move  toward  increased  leisure  time and the
     technological  revolution.  Having  identified  these themes,  we emphasize
     companies that we believe are best able to capitalize on them.

o    Firms must pass our extensive database screening,  which focuses on aspects
     such as a company's  price/earnings ratio relative to its growth rate. This
     helps us  identify a  preliminary  universe  of  companies  with  promising
     characteristics.  It also helps us capitalize  on the market's  volatility,
     because we're able to add to or initiate positions in such companies during
     periods of price weakness.

o    Prospective   purchases  must  measure  up  from  a  fundamental   research
     standpoint.  This research includes on-site visits with senior  management,
     and factors that help us gauge a company's ability to provide  consistently
     strong earnings and revenue growth.

We also employ a strict sell discipline to help manage risk.

OUR OUTLOOK FOR THE NEAR TERM
Given their strong  earnings  outlook and extremely  reasonable  valuations,  we
believe  smaller-cap  stocks,  and particularly  smaller-cap  growth stocks, are
positioned to outperform  the general  market  through the rest of 1997 and into
1998. The economic  environment  remains benign. Many smaller growth stocks sell
at significant  discounts to their earnings growth. As these companies  continue
to  deliver  earnings  growth  in  excess of the S&P 500,  we  believe  investor
confidence  will increase and valuations  will rise. We believe the portfolio is
well  positioned  to  outperform  in the coming  months,  given that the average
company  in the  portfolio  trades at what  historically  has been the  steepest
discount we have seen on  high-quality  companies.  Nonetheless,  because  small
companies  often  have  narrower  markets  and  limited   financial   resources,
investments  in these  stocks  present  more risk than  investments  in those of
larger, more established companies.


LOOKING FURTHER AHEAD
As we approach the beginning of the next century, we are truly in the midst of a
structural transformation with tremendous worldwide cultural,  political, social
and economic  implications.  We believe several of these structural changes play
to the strengths of smaller companies.

o    TECHNOLOGY  AS THE  GREAT  LEVELER.  Technology  is  eliminating  the  size
     advantage that many large companies have traditionally  enjoyed relative to
     smaller companies. Today, with technological solutions, a small company can
     often go global as quickly and effectively as a large corporation.

o    RAPID GLOBAL CHANGE. Mature economies, led by the United States, are moving
     from the  Industrial  Age to the  Information  Age.  The world is no longer
     composed of three trading blocks that move in lockstep with each other.  In
     a climate of rapid change,  successful  companies must be flexible,  agile,
     and  innovative.  We  believe  these  traits  reside to a larger  extent in
     smaller companies,  because their entrepreneurial cultures typically enable
     them to react quickly and decisively.

Thank you for your  investment in the Strong Small Cap Fund. We appreciate  your
support and we look forward to serving your investment needs in the future.

Sincerely,

2.   SIGNIFICANT ACCOUNTING POLICIES
     The following is a summary of significant  accounting  policies followed by
     the Funds in the preparation of their financial statements.

     (A)  Security  Valuation -- Portfolio  securities  traded  primarily  on  a
          principal  securities  exchange are valued at the last reported  sales
          price or the mean  between  the latest bid and asked  prices  where no
          last sales price is available.  Securities traded over-the-counter are
          valued  at the mean of the  latest  bid and  asked  prices or the last
          reported  sales  price.  Debt  securities  not  traded on a  principal
          securities  exchange are valued  through  valuations  obtained  from a
          commercial  pricing  service,  otherwise  sale or bid prices are used.
          Securities for which market quotations are not readily available, when
          held by the  Funds,  are valued at fair  value as  determined  in good
          faith under consistently  applied procedures  established by and under
          the general  supervision of the Board of Directors.  Securities  which
          are  purchased  within 60 days of their stated  maturity are valued at
          amortized cost, which approximates current value.

          The Funds may own certain  investment  securities which are restricted
          as  to  resale.   These   securities   are  valued  after  giving  due
          consideration  to pertinent  factors  including  recent private sales,
          market conditions and the issuer's  financial  performance.  The Funds
          generally bear the costs,  if any,  associated with the disposition of
          restricted  securities.   Aggregate  cost  and  fair  value  of  these
          restricted securities held at June 30, 1997 were as follows:
                                        AGGREGATE      AGGREGATE    PERCENT OF
                                          COST        FAIR VALUE    NET ASSETS

          Strong Small Cap Fund           465,000        465,000       0.3%

     (B)  Federal Income and Excise Taxes and  Distributions  to Shareholders --
          It is the  Funds'  policy  to  comply  with  the  requirements  of the
          Internal Revenue Code applicable to regulated investment companies and
          to  distribute  substantially  all of their  taxable  income  to their
          shareholders  in a manner  which  results in no tax cost to the Funds.
          Therefore, no federal income or excise tax provision is required.

          The  character  of  distributions   made  during  the  year  from  net
          investment   income  or  net  realized   gains  may  differ  from  the
          characterization for federal income tax purposes due to differences in
          the  recognition  of income and expense items for financial  statement
          and tax purposes.  Where  appropriate,  reclassifications  between net
          asset  accounts are made for such  differences  that are  permanent in
          nature.

     (C)  Realized  Gains and  Losses  on  Investment  Transactions  -- Gains or
          losses realized on investment transactions are determined by comparing
          the  identified  cost of the  security  lot sold  with  the net  sales
          proceeds.

     (D)  Futures -- Upon entering into a futures contract,  the Funds pledge to
          the broker cash or other  investments  equal to the  minimum  "initial
          margin"  requirements of the exchange.  The Funds also receive from or
          pay to the broker an amount of cash equal to the daily  fluctuation in
          the value of the  contract.  Such  receipts or  payments  are known as
          "variation  margin," and are recorded as  unrealized  gains or losses.
          When the  futures  contract  is  closed,  a  realized  gain or loss is
          recorded 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.

     (E)  Options --  Premiums  received  by the Funds upon  writing put or call
          options are recorded as an asset with a corresponding  liability which
          is  subsequently  adjusted to the current  market value of the option.
          When an option expires, is exercised,  or is closed, the Funds realize
          a gain or loss, and the liability is eliminated. The Funds continue to
          bear the risk of  adverse  movements  in the  price of the  underlying
          asset  during the period of the option,  although any  potential  loss
          during the period would be reduced by the amount of the option premium
          received.

- --------------------------------------------------------------------------------

     (F)  Foreign Currency Translation -- Investment securities and other assets
          and  liabilities   initially   expressed  in  foreign  currencies  are
          converted to U.S. dollars based upon current exchange rates. Purchases
          and sales of foreign investment securities and income are converted to
          U.S.  dollars based upon  currency  exchange  rates  prevailing on the
          respective  dates of such  transactions.  The  effect  of  changes  in
          foreign  exchange rates on realized and  unrealized  security gains or
          losses is reflected as a component of such gains or losses.

     (G)  Forward  Foreign  Currency  Exchange   Contracts  --  Forward  foreign
          currency  exchange  contracts  are valued at the forward  rate and are
          marked-to-market  daily.  The change in market value is recorded as an
          unrealized gain or loss. When the contract is closed, the Funds record
          an exchange 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.

     (H)  Additional  Investment Risk -- The use of futures contracts,  options,
          foreign   denominated   assets,   forward  foreign  currency  exchange
          contracts  and other similar  investments  for purposes of hedging the
          Funds' investment portfolios involves, to varying degrees, elements of
          market risk in excess of the amount  recognized  in the  statement  of
          assets and liabilities. The predominant risk with futures contracts is
          an imperfect  correlation  between the value of the  contracts and the
          underlying securities.  Foreign denominated assets and forward foreign
          currency  exchange  contracts may involve  greater risks than domestic
          transactions,  including currency, political and economic,  regulatory
          and market risks.

     (I)  Use of  Estimates  --  The  preparation  of  financial  statements  in
          conformity  with generally  accepted  accounting  principles  requires
          management to make estimates and assumptions  that affect the reported
          amounts of assets and liabilities and disclosure of contingent  assets
          and  liabilities  at the  date 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.

     (J)  Other -- Investment security transactions are recorded as of the trade
          date.  Dividend income and  distributions to shareholders are recorded
          on the  ex-dividend  date.  Interest income is recorded on the accrual
          basis and includes amortization of premium and discounts.

3.   RELATED PARTY TRANSACTIONS
     Strong Capital Management, Inc. (the "Advisor"), with whom certain officers
     and directors of the Funds are  affiliated,  provides  investment  advisory
     services and shareholder  recordkeeping  and related services to the Funds.
     Investment  advisory fees,  which are  established by terms of the Advisory
     Agreements, are based on annualized rates of 1.00% of the average daily net
     assets of the Funds.  Advisory  fees are  subject to  reimbursement  by the
     Advisor if the Funds' operating expenses exceed certain levels. Shareholder
     recordkeeping   and  related  service  fees  are  based  on   contractually
     established  rates  for  each  open  and  closed  shareholder  account.  In
     addition,  the Advisor is compensated for certain other services related to
     costs incurred for reports to shareholders.

     The Funds may invest cash  reserves in money  market  funds  sponsored  and
     managed by Strong Capital Management, Inc., subject to certain limitations.
     The  terms of such  transactions  are  identical  to  those of  non-related
     entitites  except that, to avoid  duplicate  investment  advisory fees, the
     Advisor  remits to each Fund an amount equal to all fees  otherwise  due to
     them under their investment  advisory  agreement for the assets invested in
     such money market funds.

     Certain information regarding related party transactions for the six months
     ended June 30, 1997, is as follows:
