CHAIRMAN'S LETTER - YEAR ENDED JUNE 30, 1998

[PHOTO]

Dear Fellow Shareholders:

   Domestic equity returns were robust during the first half of 1998, continuing
the trend of the prior three years. International equity returns however were
decidedly mixed. The crisis in Asia has affected stock markets and economies
worldwide in myriad ways creating a most interesting investment environment.

Economic Overview

   At his June 10th Joint Economic Committee testimony, Federal Reserve Chairman
Alan Greenspan gave the economy glowing praise saying, "The current economic
performance, with its combination of strong growth and low inflation, is as
impressive as any I have witnessed in my near half-century of daily
observation." While we agree, risks do exist, which are discussed below.
   With the consumer leading the way, GDP growth has been very strong over the
past four quarters. Quarter-to-quarter annualized growth over this period
measured +3.1%, +3.7%, +5.5% and +1.4%. Growth was constrained in the most
recent quarter by the just-settled strike at General Motors. Underlying consumer
spending trends remain strong. There are few reasons to believe that the
consumer juggernaut is likely to grind to a halt over the near term. Personal
income and disposable personal income, the sources of spending, are advancing at
rates consistent with or slightly higher than those of the past 18 months. The
primary risk to continued strong economic growth remains Asia where many
economies are experiencing sharp decelerations. While the U.S. trade deficit's
deterioration is not as serious structurally as in the 1980s, GDP figures may
still be impacted. We believe U.S. real GDP growth will measure +2.5% during
1998's second half.
   One year ago, Thailand floated the baht, the action that was subsequently
seen as triggering the Pacific region's economic crisis. Recently, with the
Japanese yen having weakened from 115 to 145 to the dollar, the U.S. intervened
in currency markets jointly with Japan to sell dollars and buy yen. We believe
that this and any further interventions will be insufficient to correct Japan's
inherent problems without meaningful internal structural changes. Despite the
dramatic change in the yen-dollar exchange rate, the dollar has strengthened
just 5.7% versus a trade-weighted basket of currencies representing the G-10
nations and Switzerland over the past year.
   The dollar's strength dampens inflation as imports become cheaper in dollar
terms. Inflation news has been very good, but several indices have reached
year-over-year rates of change that have been associated with cyclical bottoms
in the past. This is especially true for industrial and commodity price indices
including the NAPM Prices Paid Index, currently at a 12-year-low, and the
Commerce Department's Producer Price Index for Crude Materials. Even the
Consumer Price Index appears to have reached an intermediate bottom as the May
year-over-year figure of +1.7% represented an increase over the average +1.4%
gain for February through April. Our expectations are that the CPI will continue
to show +1.7% to +1.8% readings over the next several months. This is a very low
rate in a historical perspective, but does suggest a reversal in the trend of
declining inflation.
   Remarkably, there has been no change in the 5.50% federal funds rate since
our last annual letter to you in June 1997. Despite the rosy scenario
articulated by Chairman Greenspan mentioned above, the Federal Reserve is
"remaining watchful for signs of potential inflationary imbalances." As long as
overall inflation remains dormant and the Asian economies continue to show
weakness, we expect the Fed to maintain its policy of neutrality, but with a
bias toward tightening.
   With regard to the U.S. fiscal policy, the Congressional Budget Office raised
its estimates of the fiscal 1998 budget surplus to a range of $43 billion to $63
billion, but many private forecasters are estimating $80 billion to $90 billion.
A surplus of $175 billion is possible in fiscal 1999. As a percentage of GDP,
this would be a net surplus of +2% of GDP, representing a 6.7 percentage point
swing from the record deficit year of 1992 when the deficit was -4.7% of GDP.
While booming financial markets have produced huge capital gains for taxation
purposes, wage and salary withholding have been growing nearly ten percent
reflecting high levels of employment and a strong economy.
   A regional recession has enveloped Asia and adverse spillover effects are
being felt outside the region, particularly in countries dependent on the sale
of commodities. In a rapid decline, the Japanese yen reached an eight-year low
versus the U.S. dollar. Financial reforms are proceeding at a slow pace hindered
by strained financial resources in the rest of the region and political
considerations. Conversely,

economic momentum continues to accelerate in Europe driven by declining interest
rates and unemployment and the wealth effects of strongly rising equity markets.
Privatization and corporate restructurings on the continent are other structural
positives.

Equity Strategy Summary

   Equity returns for the Sit Mutual Funds varied widely over the past year. The
Sit Large Cap Growth Fund advanced by +35.3% while the Sit Developing Markets
Growth Fund struggled. Of course, each had very different investment climates in
which to participate. We are proud to report both funds topped their respective
benchmarks by at least five percentage points, in fact the Developing Markets
Fund surpassed the return of the MSCI Emerging Markets Free Index by nearly ten
percentage points. This may seem small solace considering the overall negative
return, but we continued to work hard to find the best opportunities in even the
most difficult market conditions.
   In our December, 1997 Semi-Annual Report letter to you, we stated our opinion
that it was unlikely that the +31.2% annualized rate achieved by the S&P 500
over the previous three years would continue. The first half of 1998, however,
proved us wrong with the S&P 500 advancing +17.7%, which if matched in the
second half of the year would imply a +38.5% return for the year. But, this
extraordinary performance has left valuations extended. Measurements such as
price-earnings, price-to-book, dividend yield and aggregate stock-values-to-GDP
ratios are all at high levels.
   Declining interest rates have been a key support for the equity market's
advance. Our contention that inflation rates have likely bottomed may make
further interest rate declines less probable. In addition, falling earnings
estimates create room for a market disappointment. We are monitoring both these
variables closely.
   Given the fact that consensus S&P 500 profit estimates are moderating, we
have been vigilantly assessing earnings growth rates for our domestic equity
funds. The 5-year projected growth rates for our Large Cap Growth, Mid Cap
Growth and Small Cap Growth Funds actually accelerated over the past year. We
believe this key characteristic was a driver of the outperformance each fund
achieved on a year-to-date basis and gives rise to confidence for the rest of
1998. Technology, health care, financial services, retail and business equipment
and services are our favored sectors.
   Internationally, emerging market risk continues to be high as Asia's
recession deepens. Latin American markets have clearly been affected by Asia's
problems. European markets could undergo a temporary correction due to the
ripple effects from the economic and market weakness in Asia and Russia and
simply pause after a stellar +26.5% return in the first half of 1998. But,
increased capital flows to Europe from Asia should continue, as return on
capital in Asia is nearly invisible. Additionally, European Monetary Union (EMU)
and increased funds from changing pension systems should be powerful positive
secular events. As is the case domestically, European valuations are stretched
in historic terms, but may not be out of line given low and declining interest
rates and a bright earnings growth picture.
   Finally, we would like to note independent third party recognition that many
of the Sit Mutual Funds have recently received. We are proud and pleased by this
recognition as it means knowledgeable sources judge that we are doing a good job
for our shareholders. Morningstar, Inc.* recently granted the Sit Large Cap
Growth Fund a five-star ranking out of 2,564 funds in the domestic stock
category for the 3-year period ended June 30, 1998 and four of our funds were
referenced in FORTUNE Magazine's list of the 221 best mutual funds in the August
17th issue.

Thank you for investing with us.

With best wishes,


/s/ Eugene C. Sit

SIT MUTUAL FUNDS
YEAR ENDED JUNE 30, 1998 PERFORMANCE REVIEW - STOCK FUNDS

                               STOCK FUNDS REVIEW

   Equity returns varied widely over the past twelve months in terms of
capitalization size, investment style and geography.
   In the United States, large cap stocks continued to perform best, largely
driven by investors desiring liquidity in an increasingly volatile market. Also,
international investors are allocating additional assets to the U.S. and appear
to be gravitating toward the largest stocks. In fact, on a year-to-date basis,
the top fifty stocks in the S&P 500 have contributed the majority of that
Index's return. Another factor that supported large cap relative performance was
superior earnings growth, though this may be changing. Several high profile
multinationals, including Boeing, Disney and DuPont, have reported disappointing
results due to adverse currency translation from a strengthening dollar and
slack Asian demand. For the year ended June 30, 1998, the large capitalization
S&P 500 Index advanced +30.2% compared with the S&P MidCap 400 Index's return of
+27.2% and a +16.5% result for the small cap Russell 2000 Index.
   Large Cap growth stocks outperformed value stocks with returns of +31.4% and
+28.8%, respectively, as measured by the respective Russell 1000 indices. The
advantage was reversed in the Small Cap Russell 2000 Index as the growth segment
rose +13.2% and the value component +19.9%.
   International investing was a case of feast or famine over the year ended
June 30, 1998. The year correlated nearly exactly with the timing of the
devaluation of Thailand's baht, which precipitated the crisis in Asia. The MSCI
Europe Index moved up +37.1%, but the MSCI Pacific Index dropped by -34.6%. We
believe Europe will benefit the from the upcoming monetary union and corporate
restructuring while Asian nations will continue to suffer from structural
challenges.

SIT LARGE CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1998

PETER L. MITCHELSON, CFA
   SENIOR PORTFOLIO MANAGER
RONALD D. SIT, CFA
   PORTFOLIO MANAGER

   Based on performance through June 30, 1998, the Sit Large Cap Growth Fund
received Morningstar's(1) highest rating of 5 stars among 2,564 funds in the
domestic stock fund category for the 3-year time period.
   The Sit Large Cap Growth Fund posted strong performance during the fiscal
year ended June 30, 1998. The Fund's total return of +35.3% compared favorably
with the +22.1% return of the Lipper Growth & Income Fund Index, and ranked in
the 2nd percentile out of 667 such funds. For 5 years, the Fund's +22.9% return
was in the 4th percentile and for 10 years its +17.3% return was in the 18th
percentile.
   The U.S. stock market recorded its unprecedented fourth consecutive year of
+30% total returns over the past 12 months driven by a continuing strong
economy, better-than-expected inflation and satisfactory profit gains, which
more than offset impacts of the Asian financial crisis. We expect economic
growth to slow in the period ahead and believe this environment will highlight
the relative attractiveness of companies with strong and predictable earnings
growth rates. The average 1998 earnings gain projected for the companies held in
the Fund is +18.9%, which is significantly higher than the broad market's +8.1%
expected increase.
   As of June 30th, the Fund was 96% invested in equities. Significant industry
weighting changes during the year included increases in the retail sector, where
we added Dayton Hudson and Lowe's Companies, and the utility sector, where we
added AirTouch Communications, Cincinnati Bell and WorldCom. Reductions occurred
in the health care sector, where we sold Amgen, Johnson & Johnson and Oxford
Health Plans, and the consumer non-durables sector, where we eliminated Campbell
Soup and Philip Morris. Technology, health care and financial services remain
the three most heavily weighted sectors.
   Assets in the Large Cap Growth Fund totaled $117.5 million at the end of
June, up from $72.2 million a year ago. We greatly appreciate shareholders'
continued interest and participation in the Fund.

                        INVESTMENT OBJECTIVE AND STRATEGY
                        ---------------------------------

     The objective of the Sit Large Cap Growth Fund is to achieve long-term
capital appreciation and, secondarily, current income. The Fund pursues this
objective by investing primarily in common stocks of medium to large size growth
companies. As of June 30, 1998, the Fund was invested exclusively in such
securities.

SIT MID CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30,1998

   SENIOR PORTFOLIO MANAGER
ERIK S. ANDERSON, CFA
   PORTFOLIO MANAGER

   A return of +22.2% was posted by the Sit Mid Cap Growth Fund for the period
ended June 30, 1998. The positive outcome was driven by investment in financial
sector stocks, which advanced +43.8% on average and comprised 16.7% of the
portfolio at June 30, and retail stocks which moved ahead +69.3% on average and
made up 11.9% of the Fund. Kohl's Corp. enjoyed the strongest advance in retail
rising +96.7% making it one of the top five holdings in the Fund. Other
noteworthy gains were posted by Dendrite International and Legato Systems,
rising +128.0% and +321.6%, respectively.
   Our allocation to retail stocks increased markedly over the past year, from
2.3% to 11.9%. Consumer confidence is high, spending is robust and these
companies are sheltered from much of Asia's turmoil. Indeed, some retailers like
Pier 1 Imports benefit from lower costs of goods sourced from the Far East.
Technology, business equipment & services, financial and health care are the
four most heavily weighted sectors, just as they were a year ago, although the
allocation to technology has decreased -5.6% and to business equipment &
services has increased by +4.2%. We will continue to employ sector rotation to
capitalize on prevailing opportunities.
   Slowing earnings growth for the market has led to mid cap growth stocks
outperforming value stocks thus far in 1998. We expect this trend to continue.
Despite slowing overall growth, earnings growth for stocks in the Fund remains
high at a forecasted rate of +25.8% and +25.4% for 1998 and 1999, respectively.
Despite forecasted earnings growth of three times that of the market, stocks
held in the Fund possess a price-to-earnings ratio (based on 1999 earnings
estimates) of 24.4 times, actually below that of the market. Attractive
valuations and stalwart growth prospects make us optimistic about the Fund's 
outlook.

                        INVESTMENT OBJECTIVE AND STRATEGY
                        ---------------------------------

   The objective of the Sit Mid Cap Growth Fund is to maximize long-term capital
appreciation. The Fund pursues this objective by investing primarily in the
common stocks of small and medium-size emerging growth companies before they
become well recognized.

   The Fund may invest in larger companies which offer improved growth
possibilities because of rejuvenated management, changes in product or some
other development that might stimulate earnings growth.

SIT SMALL CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1998

[PHOTO]

EUGENE C. SIT, CFA
   SENIOR PORTFOLIO MANAGER


   The Sit Small Cap Growth Fund's one-year return was +11.7%. While true that
larger capitalization categories delivered superior returns over the recent
past, small cap investing has captured very attractive results over full cycles.
The Fund's since-inception annualized return of +22.3% compares favorably with
the +19.1% return of the Russell 2000 Index and the +17.2% return of the Russell
2000 Growth Index over that period.
   Valuation metrics for the Fund are attractive. The 24.4 times
price-to-earnings ratio for stocks held by the Fund, is below the 24.6 times P/E
of the S&P 500 Index, based on 1999 forecasted earnings. Consistent with the
Fund's growth investing mandate, earnings for stocks in the Fund are expected to
grow +36.5% in 1998, +35.9% in 1999, and by +29.3% over the next five years. All
three rates are far in excess of what is expected for the broader market.
   The business equipment & services sector was an area of considerable success
over the past year, with the average holding rising +69.2% in value. The average
stock in the Russell 2000 Growth Index rose just +18.6%. The Fund's largest
holding, Dendrite International, was the key driver of this result, rising
+128.0%. Exposure to the sector jumped from 3.7% to 18.7% over the course of the
year. Technology was the most heavily weighted sector, as it was a year ago, and
enjoyed similarly successful stock selection. Two of the top five holdings,
Legato Systems and Uniphase Corp., increased 321.6% and 115.6%, respectively.
Stock selection was more challenging in the health care sector, and the sector
as a whole lagged small cap stocks in general. The market has rewarded visible
earnings growth, something that is lacking in many small health care issues,
even though business fundamentals may be advancing as forecast.

                        INVESTMENT OBJECTIVE AND STRATEGY
                        ---------------------------------

     The objective of the Sit Small Cap Growth Fund is to maximize long-term
capital appreciation. The Fund pursues this objective by investing primarily in
the common stocks of small companies that have a capitalization of under $500
million at the time of purchase.

     In addition, the Fund may purchase securities convertible into common
stocks, preferred stocks and warrants. The Fund may invest in securities not
listed on a national securities exchange but generally such securities will have
an established over-the-counter market.

SIT BALANCED FUND REVIEW
YEAR ENDED JUNE 30, 1998

   SENIOR PORTFOLIO MANAGER
BRYCE A. DOTY, CFA
   PORTFOLIO MANAGER


   The Sit Balanced Fund posted strong performance during the fiscal year ended
June 30, 1998. The Fund's total return of +24.0% ranked in the 8th percentile
out of 373 Balanced Funds tracked by Lipper Analytical Services, Inc. For three
years, the Fund's +21.2% return was in the 9th percentile out of 256 funds. In
addition, based on its performance through June 30, 1998, the Sit Balanced Fund
received a four-star rating from Morningstar, Inc.(1) among 2,564 funds for the
three-year time period in the domestic stock fund category
   As of June 30, 1998, the asset allocation of the Fund was 58% in equities,
38% in fixed income securities and 4% in cash reserve instruments.
   The U.S. stock market recorded an unprecedented fourth consecutive year of
+30% total returns over the past 12 months driven by a continuing strong
economy, better-than-expected inflation and satisfactory profit gains, which
more than offset impacts of the Asian financial crisis. We expect economic
growth to slow and inflation to remain subdued in the period ahead, two
conditions typically favorable for financial asset investing, in general, and
for growth stocks, in particular.
   Within the equity portion of the portfolio, we believe this environment will
highlight the relative attractiveness of companies with strong and predictable
earnings growth rates. Our heaviest industry weightings remain in technology,
financial services and health care.
   Within the fixed income portion of the portfolio, the most significant sector
shift involved increasing mortgage pass-through securities by approximately 25%
of the bond segment. The remaining sectors were reduced on a proportionate
basis. This change was made to take advantage of the widening yield spreads
resulting from increased prepayment concerns. The pass-throughs purchased are
high coupon seasoned single family mortgages that have relatively stable
prepayments.
   The Sit Balanced Fund has performed well over time in its segment of the
mutual fund marketplace, and we thank shareholders for their interest and
participation.

                       INVESTMENT OBJECTIVE AND STRATEGY
                       ---------------------------------

     The Sit Balanced Fund's dual objectives are to seek long-term growth of
capital consistent with the preservation of principal and to provide regular
income. It pursues its objectives by investing in a diversified portfolio of
stocks, bonds and short-term instruments. The Fund may emphasize either equity
securities, fixed-income securities, or short-term instruments or hold equal
amounts of each, dependent upon the Adviser's analysis of market, financial and
economic conditions.

     The Fund's permissible investment allocation is: 40-60% in equity
securities, 40-60% in fixed-income securities, and up to 20% in short-term
fixed-income instruments. At all times at least 25% of the assets will be
invested in fixed-income senior securities.

SIT INTERNATIONAL GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1998

[PHOTO]

   SENIOR PORTFOLIO MANAGER
ANDREW B. KIM, CFA
   SENIOR PORTFOLIO MANAGER

     The Fund's investment return for the year ended June 30, 1998 was +7.5%,
compared to the EAFE index benchmark return of +6.1%. The Fund's outperformance
was attributed to substantial return contributions through stock selection in
continental Europe, the U.K. and Japan. Because of the Asian contagion effect,
non-EAFE markets that represented 7.5% of the portfolio, down from 11.4% a year
ago, have not made positive contributions.
     At year-end, European holdings accounted for 72% of total assets, up
sharply from 48% a year before. The European portfolio's return was +48.7%,
exceeding by a wide margin, the index's +37.2% gain during the last 12 months.
The positive benefits of European Union (EU), corporate restructuring and
increased funds flowing into stocks due to deregulated pension systems continue
to raise equity valuations. Additionally, a cyclical upturn in European
economies is sustaining the upward earnings momentum, partially offsetting the
negative impact of the Asian turmoil. Our investments in Europe are largely
focused on high value-added products and services.
     In Japan, we continue to add value not only by having an underweight
position relative to the benchmark (61% of the index average as of June 30,
1998), but also by selecting those stocks which are restructuring and expanding
their dollar-based revenues. The market's overall index may decline further,
even after nearly a one-third drop during the last 12 months. However, the Japan
holdings are the weak-yen beneficiaries and companies with visible earnings in
niche areas even in a slumping economy, such as consumer financing and
healthcare.
     The scope and depth of the Asian financial crisis is proving to be much
greater than expected. The intensifying downward pressures on Asian currencies
are engulfing China's renminbi and the Hong Kong dollar. Given the serious
liquidity squeeze in Asia, our strategy is to limit the non-Japan weighting to
about 9%. Latin American holdings will be kept at the 2-2.5% range compared with
6.2% a year ago.

                        INVESTMENT OBJECTIVE AND STRATEGY
                        ---------------------------------

     The objective of the Sit International Growth Fund is to achieve long-term
growth of capital by investing in equity securities of issuers domiciled outside
the United States. The Fund's investment objective reflects the belief that
long-term investment planning should include the investment opportunities that
exist outside the U.S.
     The Fund selects its investments based on the characteristics of the
particular markets and economies of the countries in which it invests. Emphasis
is placed on identifying securities of companies believed to be undervalued in
the marketplace in relation to factors such as the company's revenues, earnings,
assets and long-term competitive position which over time will enhance the
equity value of the company.

SIT DEVELOPING MARKETS GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1998

     The Sit Developing Markets Growth Fund declined for the year ended June 30,
1998 by -30.5%, which compares favorably to the MSCI Emerging Markets Free
index's negative return of -40.4%. The Fund's outperformance was achieved
largely by changing the regional weighting mix. The Asian portfolio weighting
was reduced to 34.7% from 41.0% a year ago. More significant was the reduction
in Latin America to 29.6% from 38.7%. On the positive side, the European and
other markets' weighting increased to over 24.9% from 11.1%, due mainly to
larger holdings in Portugal and Israel.
     As the Asia Pacific region's recession became deeper in the quarter,
investor concerns over stock market risks were being compounded by a weaker yen.
A deflationary spiral in Japan continues to threaten the region and possibly set
off another series of competitive devaluations in the rest of Asia. One of the
few bright spots is the rapidly growing electronics sector in Taiwan where we
have increased our weighting to 8.4% from 5.9%.
     Hong Kong and Singapore portfolio weights declined to 15% of total assets
at mid-1998 vs. 18% a year ago, while Indonesia, Malaysia and Thailand combined
weightings became relatively small at 3.1%. The Philippines was an exception
(5.3%), and we added companies with significant earnings growth on a long-term
basis.
     Market volatility continued to increase in Latin America as major export
commodity prices plummeted. The Asian contagion effect also contributed to
weaker currencies. The portfolio's Latin holdings, concentrated in Brazil (11.3%
of total assets vs. the MSCI EMF index's 16.4%) and Mexico (9.3% vs. 11.9%)
offer long-term potential as economic growth is expected to be driven by the
U.S. and their own policy mix on investment and inflation. Our focus on risk
control precluded any investment in Russia.


                       INVESTMENT OBJECTIVE AND STRATEGY
                       ---------------------------------

     The objective of the Sit Developing Markets Growth Fund is to maximize
long-term capital appreciation. The Fund pursues this objective by investing in
equity securities of companies located or otherwise operating in a developing
market.

     Developing markets tend to be less economically developed regions of the
world. General characteristics also include a high demand for capital
investment, a high dependence on export markets for their major industries, a
need to develop basic economic infrastructures, rapid economic growth and lower
degrees of political stability. Investors should carefully consider the risks
associated with developing markets such as currency flucuations, high
volatility, illiquidity and the possibility of political instability.

SIT REGIONAL GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1998

[PHOTO]

EUGENE C. SIT, CFA
   SENIOR PORTFOLIO MANAGER

     The Sit Regional Growth Fund delivered a positive return of +12.6% during
the six months since its inception on 12/31/97. The Fund's positive return
lagged the return of the S&P 500 Index and that of the Russell 3000 Index due in
part to higher cash positions during the start up of the Fund. In addition,
large capitalization stocks outperformed small cap stocks during the quarter.
This favored the S&P 500 Index due to the greater number of large cap names
versus the potential for the Fund.
     The Fund is well diversified by sector. Ten sectors have weights of at
least 4%. Favored sectors continue to be financial, health care and retail.
Retail stock exposure increased by +5.2% to 12.8% in the last quarter. Strong
performance and additional purchases of leading retailers Dayton Hudson Corp.,
Walgreen Co., and Best Buy, Inc. accounted for the increased weight. All three
are top 10 holdings in the Fund and remain attractive investments given robust
consumer spending trends, personal income gains and high consumer confidence.
Value-added performance was strongest in this sector as stocks held in the Fund
advanced +41.0%, on average, versus +33.2% for retail stocks, in general, since
inception. Cash was drawn down to 1.9% from 6.6% as of the previous quarter end.
     The Fund's valuation at year end was 25.7 and 21.3 times estimated 1998 and
1999 earnings, respectively. By comparison, the S&P 500 carries
price-to-earnings multiples of 26.4 and 24.6 times, respectively. Earnings
growth for stocks in the Fund is expected to accelerate in the midst of a
decelerating environment for the market. Expected growth of +15.6% in 1998
increases to +20.1% forecasted for 1999. Given the positive fundamentals and
attractive valuations of the companies in the portfolio, we are sanguine about
the Fund's potential.


                       INVESTMENT OBJECTIVE AND STRATEGY
                       ---------------------------------

     The objective of the Fund is to maximize long-term capital appreciation.
The Fund pursues this objective by investing primarily in common stocks of
companies with their headquarters in Minnesota, Iowa, Missouri, North Dakota,
South Dakota, Nebraska, Kansas, Wisconsin, Illinois, Michigan, Indiana, and
Ohio. During normal market conditions, at least 80% of the Fund's total assets
will be invested in such securities. The Fund emphasizes securities of companies
that the Adviser believes have potential for long-term capital growth.

SIT SCIENCE AND TECHNOLOGY GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1998

[PHOTO]

EUGENE C. SIT, CFA
   SENIOR PORTFOLIO MANAGER

     The Sit Science and Technology Growth Fund delivered a positive return of
+17.7% during the six months since its inception on 12/31/97. Strong investment
results continued for the Fund as gains during the second quarter built on
robust first quarter 1998 performance. Second quarter returns were +5.5% for the
Fund, compared with a flat return for the Pacific Stock Exchange Technology 100
Index. We are pleased with the Fund's positioning, but do not expect second half
1998 results to be of equal magnitude.
     Within the S&P 500 Index, technology and health care both ranked in the top
four of fifteen sectors. As has been the case for the market at large, returns
have primarily been driven by a small number of very large capitalization
stocks. In the Russell 1000 Growth Index, Microsoft, Lucent, Cisco, and Dell
accounted for approximately two-thirds of the technology sector's year-to-date
return. All four are significant investments in this Fund.
     The Fund's price-to-earnings multiple of 29.8 times 1999 earnings appears
high compared with the S&P 500 Index's multiple of 24.6 times but is in fact
attractive given the high growth properties of the companies in this sector. In
earnings terms, that growth measures +27.1% forecasted for 1999 and +26.4% over
the forthcoming five years.
     Industry positioning was essentially unchanged during the quarter. The
weighting in the biotechnology/pharmaceuticals industry remains the most heavily
weighted industry. Profits were taken in Amgen, and shares of Warner Chilcott
were sold. Sector weighting changes were also minimal, as business equipment &
services and health care decreased modestly. Technology increased by +2.5% to
47.3%.


                       INVESTMENT OBJECTIVE AND STRATEGY
                       ---------------------------------

     The objective of the Fund is to maximize long-term capital appreciation.
The Fund pursues this objective by investing primarily in common stocks of
companies which Sit Investment Associates, Inc. expects to benefit from the
development, improvement, advancement and use of science and technology. During
normal market conditions, at least 80% of the Fund's total assets will be
invested in such securities. The Fund emphasizes securities of companies that
the adviser believes have potential for long-term capital growth.

SIT MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


The Sit Mutual Funds (the Funds) are 100% no-load funds, and are registered
under the Investment Company Act of 1940 (as amended) as diversified, open-end
management investment companies, or series thereof. The Sit Developing Markets
Growth, Sit Small Cap Growth, Sit International Growth, Sit Balanced, Sit
Regional Growth and Science and Technology Growth Funds are series funds of Sit
Mutual Funds, Inc..

The Regional Growth and Science and Technology Growth Funds commenced operations
on December 31, 1997. The only transactions for these funds prior to that date
was the sale of 10 shares for $100 in each of the funds to Sit Investment
Associates, Inc. on December 23, 1997.

This report covers the stock funds of the Sit Mutual Funds. The investment
objective for each Fund is as follows:

         FUND                               INVESTMENT OBJECTIVE

       Large Cap Growth               Maximize long-term capital appreciation 
                                      and, secondarily current income.

       Mid Cap Growth                 Maximize long-term capital appreciation.

       Small Cap Growth               Maximize long-term capital appreciation.

       Balanced                       Long-term capital appreciation consistent
                                      with the preservation of principal and to
                                      provide regular income.

       International Growth           Maximize long-term capital appreciation.

       Developing Markets Growth      Maximize long-term capital appreciation.

       Regional Growth Fund           Maximize long-term capital appreciation.

       Science and Technology Growth  Maximize long-term capital appreciation.

Significant accounting policies followed by the Funds are summarized below:


INVESTMENTS IN SECURITIES

Investments in securities traded on national or international securities
exchanges or on the NASDAQ National Market System are valued at the last quoted
sales price prior to the time when assets are valued; securities traded in the
over-the-counter market and listed securities for which no sale was reported on
that date are valued at the last bid price; foreign securities that are
purchased in the form of American Depository Receipts (ADRs) are valued in
United States dollars at the latest quoted price on the national securities
exchange on which the ADR is traded. When market quotations are not readily
available, securities are valued at fair value based on procedures determined in
good faith by the Board of Directors. Such fair values are determined using
prices quoted by independent brokers or pricing services. Securities maturing
more than 60 days from the valuation date are valued at the market price or
approximate market value based on current interest rates; those securities with
maturities of less than 60 days when acquired, or which subsequently are within
60 days of maturity, are valued at amortized cost, which approximates market
value.

Security transactions are accounted for on the date the securities are purchased
or sold. Securities gains and losses are calculated on the identified-cost
basis. Dividend income is recorded on the ex-dividend date or upon the receipt
of ex-dividend notification in the case of certain foreign securities. Interest,
including level-yield amortization of long-term bond premium and discount, is
recorded on the accrual basis.

Delivery and payment for securities which have been purchased by the Balanced
Fund on a when-issued basis can take place a month or more after the transaction
date. During this period, such securities are subject to market fluctuations and
may increase or decrease in value prior to delivery. The Fund maintains, in a
segregated account with its custodian, assets with a market value equal to the
amount of its purchase commitments. As of June 30, 1998, the Balanced Fund had
entered into when-issued commitments of $63,700.

ILLIQUID SECURITIES

Each Fund currently limits investments in illiquid securities to 15% of net
assets. At June 30, 1998, the Developing Markets Growth Fund and Small Cap
Growth Fund held investments in securities deemed illiquid by the investment
adviser. The aggregate value of such securities at June 30, 1998, was $603,780
and $315,806, representing 5.2% and 0.5% of the Fund's net assets, respectively.
Pursuant to the guidelines adopted by the Board of Directors, certain
unregistered securities are determined to be liquid and are not included within
the limitation specified above.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS

The market value of securities and other assets and liabilities denominated in
foreign currencies for Developing Markets Growth Fund and International Growth
Fund are translated daily into U.S. dollars at the closing rate of exchange.
Purchases and sales of securities, income and expenses are translated at the
exchange rate on the transaction date. Dividend and interest income includes
currency exchange gains (losses) realized between the accrual and payment dates
on such income. Exchange gains (losses) may also be realized between the trade
and settlement dates on security and forward contract transactions. For
securities denominated in foreign currencies, the effect of changes in foreign
exchange rates on realized and unrealized gains or losses is reflected as a
component of such gains or losses.

The Developing Markets Growth and International Growth Funds may enter into
forward foreign currency exchange contracts for operational purposes and to
protect against adverse exchange rate fluctuation. The net U.S. dollar value of
foreign currency underlying all contractual commitments held by the Funds and
the resulting unrealized appreciation or depreciation are determined using
foreign currency exchange rates from an independent pricing service. The Funds
are subject to the credit risk that the other party will not complete the
obligations of the contract.

At June 30, 1998, the Developing Markets Growth Fund and International Growth
Fund had entered into foreign currency exchange contracts that obligate the Fund
to deliver currencies at specified future dates. The unrealized appreciation
and/or depreciation on these contracts is included in the accompanying financial
statements. The terms of the open contracts are as follows:

FEDERAL TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to shareholders. Therefore, no income tax provision is required.
Also, in order to avoid the payment of any federal excise taxes, the Funds will
distribute substantially all of their net investment income and net realized
gains on a calendar year basis.

Net investment income and net realized gains may differ for financial statement
and tax purposes. The character of distributions made during the year for net
investment income or net realized gains may also differ from its ultimate
characterization for tax purposes. Also, due to the timing of dividend
distributions, the fiscal year in which amounts are distributed may differ from
the year that the income or realized gain (losses) were recorded by the fund.

Undistributed net investment income and accumulated net realized gains (losses)
from the Statement of Changes in Net Assets have been increased (decreased) by
current permanent book-to-tax differences resulting in reclassification of
additional paid-in capital as follows:

                                  Undistributed    Accumulated        Additional
                                   net invest.     net realized         paid-in
                                     income       gains (losses)        capital
                                     ------       --------------        -------

Developing Markets Growth             72,295          20,693            (92,988)
Small Cap Growth                     466,768            ----           (466,768)
International Growth                 131,014        (131,014)              ----

Science and Technology Growth          3,908            ----             (3,908)

For federal income tax purposes the Developing Markets Growth Fund has a capital
loss carryover of $935,567 at June 30, 1998 which, if not offset by subsequent
capital gains, will begin to expire in 2004. It is unlikely that the Board of
Directors will authorize a distribution of net realized gains until the
available capital loss carryover is offset or expires.

DISTRIBUTIONS

Distributions to shareholders are recorded as of the close of business on the
record date. Such distributions are payable in cash or reinvested in additional
shares of the Funds' capital stock. Distributions from net investment income, if
any, are declared and paid quarterly for the Balanced Fund and declared and paid
annually for Regional Growth, Science and Technology Growth, Developing Markets
Growth, Small Cap Growth, International Growth, Mid Cap Growth, and Large Cap
Growth Funds. Distributions from net realized gains, if any, will be made
annually for each of the Funds.

NOTE 2 - INVESTMENT SECURITY TRANSACTIONS

CONCENTRATION OF INVESTMENTS

The Developing Markets Growth Fund may concentrate investments in countries with
limited or developing capital markets which may involve greater risks than
investments in more developed markets and the prices of such investments may be
volatile. The consequences of political, social or economic changes in these
markets may have disruptive effects on the market prices of the Fund's
investments and the income it generates, as well as the Fund's ability to
repatriate such amounts.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make certain 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 results. Actual results could differ from those
estimates.

Purchases of and proceeds from sales and maturities of investment securities,
other than short-term securities, for the period ended June 30, 1998, were as
follow:

                                                  Purchases         Proceeds

NOTE 3 - EXPENSES

Investment Associates Inc. (SIA), under which SIA manages the Fund's assets and

SIA is obligated to pay all of the Funds' expenses (excluding extraordinary
expenses, stock transfer taxes, interest, brokerage commissions and other
transaction charges relating to investing activities).

For the period November 1, 1996 through December 31, 1998 the Adviser has agreed
to limit the management fee (and, thereby, all fund expenses, except those not
payable by the fund as set forth above) of the Mid Cap Growth Fund to 1.00% of
the Fund's average daily net assets. For the period January 1, 1994 through
December 31, 1998, the Adviser has agreed to limit the management fee (and,
thereby, all fund expenses, except those not payable by the fund as set forth
above) of the International Growth Fund to 1.50% of the Fund's average daily net
assets. For the period January 1, 1998 through December 31, 1998, the Adviser
has agreed to limit the management fee (and, thereby, all fund expenses, except
those not payable by the fund as set forth above) of the Regional Growth and
Science and Technology Growth Funds to 1.00% and 1.25%, respectively, of the
Fund's average daily net assets. After December 31, 1998, these voluntary fee
waivers may be discontinued by the Adviser in its sole discretion. During the
period ended June 30, 1998, for the International Growth, Mid Cap Growth,
Regional Growth and Science and Technology Growth Funds, SIA voluntarily
absorbed an additional $338,651, $1,004,074, $3,611 and $4,655 respectively, in
expenses that were otherwise payable by the Funds.

As of June 30, 1998, the Large Cap Growth Fund, International Growth Fund, and
Mid Cap Growth Fund had invested $1,000,000, $500,000, and $1,000,000,
respectively, in the Sit Money Market Fund. The terms of such transactions were
identical to those of non-related entities except that, to avoid duplicate
investment advisory fees, SIA remits to each Fund an amount equal to all fees
otherwise due to them under their investment management agreement for the assets
invested in the Sit Money Market Fund.

INVESTMENT SUB-ADVISER

SIA has entered into a sub-advisory arrangement with an affiliated international
investment adviser, Sit/Kim International Investment Associates, Inc. ("SKI").
SKI provides investment research information and portfolio management service
for the Developing Markets Growth Fund and International Growth Fund. Generally,
as compensation for its services under the sub-advisory agreement, SIA pays SKI
a monthly fee of 1/12 of .75% on the first $100 million of each Fund's average
daily net assets, 1/12 of .50% on the next $100 million of average daily net
assets and 1/12 of .40% of average daily net assets in excess of $200 million.
SKI has agreed to waive any fees under the agreement to the extent that
cumulative out of pocket expenses of each Fund borne by SIA exceed the
cumulative fees received by SIA pursuant to each Fund's investment management
agreement. In accordance with the Agreement, fees of $732,239 were paid or
payable to SKI for the year ended June 30, 1998.

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

(1) Total investment return is based on the change in net asset value of a share
    during the period and assumes reinvestment of distributions at net asset
    value.

(2) During the years ended June 30, 1997, 1996, 1995 and 1994, the investment
    adviser voluntarily absorbed $50,548, $110,099, $132,305 and $112,191
    respectively, in expenses that were otherwise payable by the Fund. Had the
    Fund incurred these expenses, the ratio of expenses to average daily net
    assets would have been 1.08%, 1.23%, 1.35% and 1.40% for the years ended
    June 30, 1997, 1996, 1995, and 1994 respectively, and the ratio of net
    investment income(loss) to average daily net assets would have been
    0.11%,(.09%), 0.07%, and 0.59% respectively.

(3)  Beginning in fiscal 1997, the Fund is required to disclose an average
     brokerage commission rate. This rate is calculated by dividing total
     brokerage commissions paid on purchases and sales of portfolio securities
     by the total number of related shares purchased and sold.

                                                                              51

(1) Total investment return is based on the change in net asset value of a share
    during the period and assumes reinvestment of distributions at net asset 
    value.

2)  Effective November 1, 1996, total Fund expenses are contractually limited
    to 1.25% of average daily net assets. However, during the years ended June
    30, 1998 and 1997, the investment adviser voluntarily absorbed $1,004,074,
    and $609,840, respectively, in expenses that were otherwise payable by the
    Fund. Had the Fund incurred these expenses, the ratio of expenses to average
    daily net assets would have been 1.25% and 1.09% for the years ended June
    30, 1998 and 1997, respectively, and the ratio of net investment income
    (loss) to average daily net assets would have been (0.66%) and (0.37%),
    respectively.

(3) Beginning in fiscal 1997, the Fund is required to disclose an average
    brokerage commission rate. This rate is calculated by dividing total
    brokerage commissions paid on purchases and sales of portfolio securities by
    the total number of related shares purchased and sold.

(1) Total investment return is based on the change in net asset value of a share
    during the period and assumes reinvestment of distributions at net asset
    value.

(2) Beginning in fiscal 1997, the Fund is required to disclose an average
    brokerage commission rate. This rate is calculated by dividing total
    brokerage commissions paid on purchases and sales of portfolio securities by
    the total number of related shares purchased and sold. The comparability of
    this information may be affected by the fact that commission rates per share
    vary significantly among foreign countries.

request confirmations from brokers and where replies are not received, we carry

accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our

referred to above present fairly, in all material respects, the financial
