CHAIRMAN'S LETTER - YEAR ENDED JUNE 30, 1999

[PHOTO]

Dear Fellow Shareholders:

     Despite considerable volatility in the global economic environment marked
by investor concerns first of deflation in late 1998 and then inflation in
mid-1999, most major equity market indices moved solidly higher over the last
twelve months.

Economic Overview

     June represented the 100th month of the U.S. economic expansion, a long
cycle characterized by positive and balanced growth, generally declining
interest rates, subdued inflation, and record-setting gains in aggregate
employment. The resilience of consumer spending continues to be the primary
driver behind the above-trend growth for the U.S. economy. Over the last four
quarters, annualized growth in Gross Domestic Product (GDP) has averaged +4.1%,
a remarkable achievement given the turmoil in many economies throughout the
world. Since Personal Consumption Expenditures (PCE) now account for over
two-thirds of GDP, the +5.0% year-over-year gain over the last twelve months was
strong enough to overcome weakness in other components, particularly the severe
decline in net exports. Several factors suggest that real GDP growth will be
somewhat below the pace witnessed over the past year, although above the +2.3%
rate for the second quarter. First, consumer spending appears to be
decelerating, as second quarter PCE increased by +4.0%, down from the increase
of +6.7% in the first quarter. Second, we do not believe that consumer spending
will remain as robust if the savings rate continues in negative territory.
Third, fixed mortgage rates have increased nearly 100 basis points since the
beginning of the year, which has served to impede housing demand; however, given
the generally strong level of consumer confidence and continued high levels of
housing investment and consumer durables spending, together with capital
investment by business, we expect only a modest slowing in GDP growth for the
remainder of the year compared to the robust +4.1% average over the past twelve
months. Our expectation for calendar 1999 GDP growth is +3.8%.

     In terms of inflation data, the news remains mixed. May and June Consumer
Price Index (CPI) reports showed no change from the previous month, which was
considerably better than expectations. The National Association of Purchasing
Managers Prices Paid Index, however, has increased for six consecutive months,
and although the June Producer Price Index showed a decrease for finished goods,
there have been monthly increases in intermediate and crude goods.

     The government's data releases on July 29th also contained mixed messages.
While GDP growth slowed to +2.3% in the second quarter, the
stronger-than-expected +3.2% year-over-year increase in the Employment Cost
Index was greeted negatively. Inflation news will continue to be watched
intensely, but we expect only a moderate pick-up in the CPI data, which should
range between +2.0% and +2.5% for 1999.

     The Federal Reserve continues to be highly sensitive to inflation as
evidenced by its modest 25 basis point increase in the federal funds rate. More
importantly, the Fed changed its policy stance from a "tightening" to a
"neutral" bias, reducing fears of successive near-term rate increases. The
Chairman's recent Humphrey-Hawkins testimony indicated that inflation continues
to be a concern, despite the recent change in bias.

     As Mr. Greenspan stated in his address, "If new data suggest it is likely
that the pace of cost and price increases is picking up, the Federal Reserve
will have to react promptly and forcefully so as to preclude imbalances from
arising that would only require a more disruptive adjustment later."

     Among his key concerns are the tightness in the labor market, the
sustainability of productivity gains, and the potential ramifications of a stock
market "bubble." In terms of Federal Reserve policy, given our outlook for only
a modest acceleration in consumer inflation and a slight deceleration in GDP in
the second half of 1999, we believe the Fed may rest after one or two more 25
basis point increases.

     In terms of fiscal policy, escalating projections of federal budget
surpluses have tax-cut proponents calling for aggressive tax reductions--
especially since the non-Social Security operating surplus may be achieved as
early as fiscal-year 2000. If one can believe the typically overly optimistic
government projections, $2.9 trillion in total surpluses would be generated over
the next decade of which $1 trillion would be outside the Social Security
buildup. Tax bills are being worked on in both the House and Senate and, under
the most optimistic assumptions, a bill might be ready for the President by the
fall. If Democrats and Republicans fail to compromise on the myriad of issues
within a tax bill, the topic of taxation will be a focal issue in the 2000
election campaign. Another key fiscal event occurred in late June when the
President outlined a Medicare reform package. This included a prescription drug
program with a tax-cut-for-Medicare-drug-benefit deal also a possibility. The
new drug benefit is estimated to cost $118 billion over ten years with 60%
financed by what the Clinton administration has termed "savings from competition
and efficiency" and 40% from the expected surplus.

     From an international perspective, the outlook for global

2

economic growth continues to improve. Asian economies appear to be slowly
recovering from the "trough" experienced in fall of 1998. The Japanese economy,
most notably, is showing some signs of life. GDP growth in the most recent
quarter was a surprisingly strong +1.9%. Industrial production increased +3.0%
in June, and recent Bank of Japan business sentiment surveys have shown an
improvement over the March survey. Since the beginning of the year, various
European economies had mixed growth results that have led to an overall
slowdown. Weakness in Germany, Euroland's largest economy, has been a major
concern. We believe, however, that the German economy will be improving, largely
due to recovering Asian markets coupled with euro weakness, which has prompted
an improvement in exports. Thus far in 1999, Latin American financial markets
responded favorably to stabilization in the currencies; however, the region's
economies remain weak because many Latin American countries are large producers
of worldwide commodities whose prices, except for oil, remain depressed. We are
forecasting +2.0% global GDP growth in 1999, due to accelerating growth in
Europe, improving economic growth prospects in non-Japan Asia, bottoming of the
recession in Japan, and gradual slowing in the United States.

Equity Strategy Summary

     Domestic stock indices were generally higher over the last twelve months,
with virtually all mid and large capitalization indices posting double-digit
returns. Two major changes in investment sentiment that may have future
investment implications occurred during the second quarter of 1999. First,
although larger cap issues have dramatically outperformed smaller stocks over
the past year (the Russell 1000 outperfomed the Russell 2000 by over 20
percentage points), small stocks came to life in the second quarter of 1999.
Extreme undervaluation of small stocks and renewed confidence in the global
economic environment were key elements behind the strong second quarter rally
for small cap stocks. In fact, this was the first quarter in seven that the
Russell 2000 Index outperformed the Russell 1000 Index. Given the duration and
magnitude of small cap underperformance in recent years, and the resulting
valuation disparity, we believe the potential exists for an extended small cap
rally. The second significant change in equity markets was the rebound in
economically sensitive, cyclical issues that had previously been depressed by
fears of an economic slowdown. While we believe that the economic backdrop has
generally improved the prospects for cyclical companies, it appears that a
significant portion of the anticipated improvement in the earnings cycle has
already been discounted in stock prices.

     Although the rise in interest rates has caused volatility in the equity
markets, stocks have been able to advance because corporate earnings news has
been generally positive. It appears as though second quarter operating earnings
for the S&P 500 Index will show solid double-digit growth, and we estimate that
over two-thirds of companies were able to exceed analysts' consensus
expectations. Although a brightening earnings outlook has prompted a tug-of-war
among small cap/large cap and growth/value investment styles in recent months,
our expectation for a moderately slowing U.S. economy implies a continued
positive environment for growth stock investing.

     Despite some valuation measures for the stock market being at extended
levels, many companies within the S&P 500 Index below the top 20 in
capitalization are at reasonable valuations in the context of current interest
rates and inflation levels. While the current S&P 500 Index
capitalization-weighted price-to-earnings ratio of 28.3x is the highest in 35
years, the median valuation is a much more reasonable 20.3x. These statistics
suggest that the very largest stocks in the Index (including such names as
Microsoft, GE, and Coca Cola) are disproportionately raising
capitalization-weighted valuation measures and obscuring the more reasonable
valuation for the broader market.

     International investment performance has varied widely among markets so far
in 1999. There is continued evidence of an improving global economy fueled by
particularly strong performance in emerging markets. While sluggish economic
growth and investors' reallocation of assets to Asia have caused some weakness
in European equity markets, we believe performance will improve as key European
economies slowly improve, corporate restructuring continues, and mergers and
acquisition activity accelerates. Brightened economic prospects have led us to a
much more positive view on Asia, particularly Japan. Concerns over upcoming
elections and the region's economic reliance on commodity prices have led us to
underweight Latin America versus global benchmarks.

     We greatly appreciate your support as shareholders in the Sit Mutual Funds.
With your investment objectives always in mind, we remain committed to seeking
out the best investment opportunities throughout the world.

YEAR ENDED JUNE 30, 1999  PERFORMANCE REVIEW - STOCK FUNDS

                               STOCK FUNDS REVIEW

     Despite a great deal of quarterly volatility, global equity returns were
generally positive over the past twelve months.

     In the United States, large capitalization stocks continued to outperform
smaller issues, but there were signs of improvement in small cap stocks in the
latest quarter. For the year ended June 30, 1999, the S&P 500 Index total return
was +22.8%, over twenty percentage points higher than the +1.5% return for the
Russell 2000 Index. While small and mid cap stock cumulative returns over the
last twelve months were relatively moderate, investment sentiment may be
changing based on the strong performance in the most recent quarter. For the
quarter ending June 30, 1999, the Russell 2000 Index returned +15.6%,
considerably higher than the +7.1% return for the S&P 500 Index. Largely due to
fears of a global slowdown that persisted over the period, particularly in the
second half of 1998, growth stocks posted very strong results relative to value
issues. The Russell 1000 Growth Index advanced +27.3% over the past twelve
months, while the Russell 1000 Value Index increased by +16.4%. The Russell 2000
Growth Index return of +8.3% was fourteen percentage points higher than the
- -5.7% return for the Russell 2000 Value Index.

   Technology stocks, which are typically overweighted in Sit Mutual Funds
equity portfolios, performed exceptionally well over the past twelve months.
Within the Russell 1000 Growth Index, for example, both the Electronic
Technology and Technology Services sectors produced returns of over +60%.
Economically sensitive groups, including producer manufacturing,
consumer-durables, and process industries, lagged the market averages over the
period.

     International equity market indices also moved higher over the last twelve
months, although results varied widely by geographic region. The MSCI EAFE Index
gained +7.6%, with strong returns in most Asian markets offsetting somewhat
lackluster returns in Europe. Continued evidence of an economic recovery in
emerging markets has led to strong returns for the MSCI Emerging Markets Free
Index, which advanced +25.2% over the past twelve months, with almost all of the
gains occurring during the second quarter of 1999.

SIT BALANCED FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGERS

           BRYCE A. DOTY, CFA

     The Sit Balanced Fund posted strong returns for the fiscal year ended June
30, 1999. The Fund's total return was +11.3%. The Lehman Aggregate Bond Index
gained +3.2% over the last twelve months while the S&P 500 Index increased
+22.8%. For the quarter ended June 30th, the Fund gained +0.5% while the Lehman
Aggregate Bond Index declined -0.9% and the S&P 500 gained +7.1%.

     As of June 30, 1999, the asset allocation of the Fund was 54% equities
(down from 56% at the end of March), 37% fixed income securities (down from
38%), and 9% cash reserve instruments (up from 6%).

     The equity portion of the portfolio produced solid returns over the last
twelve months, and investors are now focusing on improving earnings prospects
for U.S. companies amid an improved global economy. We believe that the market's
focus on strong earnings growth will benefit the equity securities held in the
Fund. As of June 30th, the projected growth rate for companies held in the Fund
was +21.6%, which is more than twice the projected growth rate for the S&P 500.
The Fund's holdings are concentrated in high unit growth companies with unique
products and strong management teams able to thrive in an intensely competitive
global business environment. This leads to significant positions in technology
and health care. We will continue to underweight slow growth, commodity-oriented
companies, and generally avoid such industries as chemicals, papers, autos, and
heavy equipment and machinery.

     While the improving global economy fueled the rally in equities over the
last quarter, bond prices suffered from fears over excessive economic growth.
Since bottoming at a 4.7% yield on October 5, 1998, U.S. Treasury bond yields
have risen about 130 basis points, and stood at just under 6% at the end of the
quarter. A recent change in fixed income strategy includes a sector shift to
increase U.S. Treasuries. In the coming months, we expect weakness in some
non-government sectors as investors become cautious due to of the Y2K
phenomenon. We are also increasing emphasis on securities with 5- to 10- year
average lives, which reflects a very flat yield curve that has reduced the
attractiveness of longer-maturity securities. The Fund will continue to focus on
high-quality securities that offer attractive total return opportunities.


                        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 LARGE CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

     The Sit Large Cap Growth Fund posted strong performance during the fiscal
year ended June 30, 1999. The Fund's total return of +15.1% compared favorably
with the +13.6% return for the Lipper Growth and Income Index. Within the Lipper
Growth and Income Fund universe, the Fund's 1-year, 5-year and 10-year
annualized return was in the 47th, 8th and 17th percentile, respectively.

     Most U.S. stock market indices posted impressive gains over the last twelve
months, driven largely by continued strength in the domestic economy. Despite
lingering effects of the Asian crisis in the fall of 1998, and the subsequent
rise in interest rates, stock market returns have broadened considerably thus
far in 1999, and many indices are reaching or approaching new highs. Although a
brightened earnings outlook has prompted a tug of war among small/large cap and
growth/value investment styles in recent months, our expectation for a
moderately slowing U.S. economy implies a continued positive environment for
growth stock investing. Securities in the Fund continue to maintain projected
earnings growth rates far in excess of S&P 500 averages. In each of the next two
years, projected growth rates for securities held in the Fund exceed +20%, which
is more than twice the expected earnings gain for the S&P 500. Furthermore, as
inflation fears have subsided, growth stocks have significantly outperformed
value issues as the perception of risk surrounding their higher
price-to-earnings valuations has diminished.

     As of June 30th, the Fund was 93% invested in equities. Significant sector
weighting changes during the past year include increases in electronic
technology and health technology through the additions of Sun Microsystems,
International Business Machines, Raytheon, United Technologies, American Home
Products, and Amgen. Sector weighting decreases occurred in financial services
and consumer non-durables through the reduction or elimination of positions in
Citigroup, Franklin Resources, Mercury General, Unilever, and Gillette.

     Net assets in the Fund totaled $140.3 million at the end of June, up from
$117.5 million a year ago. We very much appreciate shareholders' continued
interest and participation in the Fund.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Large Cap Growth Fund is to maximize long-term capital
appreciation. The Fund pursues this objective by investing primarily in common
stocks of growth companies with a capitalization of $5 billion or more at the
time of purchase.

SIT REGIONAL GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGER
           EUGENE C. SIT, CFA

     The Sit Regional Growth Fund rose +17.2% during the past year, while the
S&P 500's return was +22.8%. For the last quarter, the Fund's return was +7.0%
compared to the +7.1% return for the S&P 500. The Fund's performance
differential to the Index was essentially due to underweightings in the very
large companies outside of the Fund's regional focus. The Fund's cumulative
+32.0% return since inception, although lagging behind the
capitalization-weighted S&P 500 return, actually exceeds the estimated
equal-weighted capitalization return of +30.8% for the S&P Index. Because the
Fund's capitalization remains well below the popular large cap indices, the
widening breadth of the market during the second quarter bodes well for improved
relative performance going forward.

     Strong earnings growth continues to be the primary focus of the portfolio.
We project earnings growth rates of more than +21% for the next two
years--approximately three times the projected growth estimates for the S&P
500--for securities held in the Fund. Our enthusiasm for the Fund is based on
the attractive valuation relative to the market. Despite significantly higher
projected earnings growth rates, the Fund's weighted price-to-earnings valuation
is 26 (based on 1999 estimates), which is equivalent to the current earnings
multiple of the S&P 500.

     As of June 30th, the Fund was 95% invested in equity securities.
Significant sector weighting changes during the past year included increases in
electronic technology and technology services through the additions of Motorola,
National Computer Systems, Compuware, and First Data. Sector weighting decreases
occurred in financial services and health technology through the reduction or
elimination of positions in Charter One Financial, Household International,
Progressive, Hillenbrand, Stryker, and RP Scherer. Given the Fund's emphasis on
growth companies with unique product attributes, overweighted positions remain
in electronic technology and technology services.

     Given the Fund's strong earnings growth prospects, attractive valuations,
and existing opportunities within our geographic region, we remain enthusiastic
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,

SIT MID CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

     During the June quarter of 1999, mid cap growth stocks rebounded strongly
and outperformed large cap growth stocks, as measured by the Frank Russell
Indices, for the first time in seven quarters. The Fund's quarterly return of
+11.2% compared favorably with the +10.4% return for the Russell Mid Cap Growth
Index.

     For the year ended June 30, 1999, the Sit Mid Cap Growth Fund return was
+6.9% versus the +20.3% for the Russell Mid Cap Growth Index. Although the
Fund's performance has lagged behind the Index, our capitalization restrictions
and valuation disciplines resulted in limited exposure to areas which drove the
Index higher, namely large stocks with capitalizations greater than $10 billion
and Internet stocks. For example, we estimate that just two stocks, Yahoo! and
Charles Schwab, contributed approximately +4.5% to the +20.3% return for the
Index over the last year. These companies have current market capitalizations of
over $35 billion and are well in excess of our Fund parameters.

     The recent outperformance of smaller cap issues can be attributed to
attractive valuations and renewed confidence in the global economy. Given the
dramatic differences in performance between mid and large cap issues over the
last two years, the potential for small and medium cap issues to catch up still
exists. Although the much publicized rally in cyclical stocks lifted value
stocks higher during the second quarter, growth issues in the mid cap sector
have significantly outperformed value issues on a year-to-date and twelve-month
basis. We believe that the Fund is very well positioned to capitalize on the
renewed market enthusiasm for smaller cap issues. The portfolio's average
projected earnings growth rate of +25% vastly exceeds the S&P 500's projected
growth rate of +10%.

     Significant sector weighting changes during the past year include increases
in electronic technology and health technology through the additions of
Uniphase, Vitesse Semiconductor, Jabil Circuit, Applied Micro Devices, and
Lexmark International. Sector weighting decreases occurred in financial services
and health services through the reduction or elimination of positions in First
American of Tennessee, Nac Re, Mercury General, McKesson HBOC, and Healthsouth
Corporation. As of June 30th, the Fund was 94% invested in equities.

     Given mid cap stocks' renewed momentum and strong growth prospects for the
companies in the portfolio, we remain 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 growth companies with a capitalization of $2 billion to $15
billion at the time of purchase.

SIT INTERNATIONAL GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGERS
           EUGENE C. SIT, CFA
           ANDREW B. KIM, CFA
           ROGER J. SIT

     The Sit International Growth Fund's 1-year return of +4.5% compares with
the MSCI EAFE Index gain of +7.6% and the Lipper International Fund Index rise
of +4.0%. A major reason for the Fund's underperformance relative to the EAFE
Index was a sector rotation from growth to cyclical stocks in the first half of
1999. Market participants anticipated a faster pace of global economic growth
accompanied by an upturn in basic commodity prices.

     The Russian default in August 1998 was one of the most traumatic
experiences for the international markets last year. The EAFE Index declined
- -14.2% in the three months ended September 30, 1998, in part due to the
potential crisis associated with Long- Term Capital Management in the U.S.
Fortunately, the international equity markets were able to recover
substantially, enabling the Index to record a +20.7% gain in the December
quarter. Moreover, the first half of 1999 witnessed a lessening of market
volatility despite Brazil's currency devaluation. For the first six months of
1999, the Index increased by a modest +4.0%.

     Notably, the first half of 1999 was marked by an unexpectedly steep
depreciation of the euro (down -13%). As a result, the Fund's European portfolio
holdings declined in the Netherlands, Belgium, Ireland and the U.K.
Subsequently, the euro began to rebound against the dollar in July in response
to indications of improved economic growth in Germany and the U.K. We expect the
euro's upward trend to continue in the remainder of 1999, and we are targeting a
European portfolio weighting of 62%, up from 58.3% at the end of June.

     The Fund's Pacific Basin holdings increased to 12.9% of total assets vs.
the Index weighting of 6.6% due to the accelerating speed of recovery in the
crisis economies of Asia and ample liquidity. Recording substantial gains in
dollar terms were the Fund's holdings in Korea, Thailand and Hong Kong.

     From a long-term perspective, the upward momentum in the Japanese market is
even more significant now that a relapse in the economy appears unlikely;
therefore, the Fund's Japanese weighting climbed to 25.0% at mid-1999 (from
12.8% a year ago), compared with 24.0% for the Index. The Fund partially hedged
its Japanese holdings in early July to protect local currency gains in the
future. We expect renewed yen weakness based on a resumption of Japanese capital
outflow and a decreasing current account surplus.


                        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 SMALL CAP GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  EUGENE C. SIT, CFA
           SENIOR PORTFOLIO MANAGER

     The Sit Small Cap Growth Fund's one-year return was +8.8% and compared
favorably to the +1.5% return for the Russell 2000 Index. Small cap stocks
regained significant momentum during the second quarter of 1999. The Fund's
quarterly return was +18.7% versus the +15.6% return for the Russell 2000 Index.
The Fund's average annual total return since inception was +19.4%, which
compared favorably to the +15.3% return for the Russell 2000 Index.

     Extreme undervaluation of small stocks and renewed confidence in the global
economic environment were key elements behind the strong second quarter rally
for small cap stocks. In fact, this was the first quarter in seven that the
Russell 2000 Index outperformed the Russell 1000 Index. Given the duration and
magnitude of small cap underperformance in recent years and the resulting
valuation disparity, we believe the potential exists for an extended small cap
stock rally. Our enthusiasm for smaller stocks can be illustrated by a simple
analysis of price-to-earnings ratios relative to estimated long-term growth
rates. The P/E ratio for the Fund currently stands at 32 times estimated year
2000 earnings--which is BELOW the estimated earnings growth rate of 35%. In
contrast, the P/E ratio for the S&P 500 is 26 times estimated 2000 earnings and
well ABOVE the long-term earnings growth rate of 10%.

     As of June 30th, the Fund was 96% invested in equities. The most
significant sector increases over the past year occurred in electronic
technology through purchases of Applied Micro Circuits, PMC Sierra, Galileo
Technology, and Flextronics. The financial services sector had the greatest
reduction in weighting, accomplished through sales of Imperial Credit
Industries, Life Re, Nac Re, Delphi Financial, and Community First Bank.
Electronic technology and technology services remain the heaviest weighted
sectors within the portfolio due to the robust earnings outlook for the
technology sectors.

     Although the strong returns experienced during the second quarter are
unlikely to be repeated over each of the year's remaining quarters, we believe
the Fund is in position to benefit from the improving outlook for small
capitalization investing.


                        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 growth companies that have a capitalization of $2.5
billion or less 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 SCIENCE AND TECHNOLOGY GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  EUGENE C. SIT, CFA
           SENIOR PORTFOLIO MANAGER

     The Sit Science and Technology Fund posted a positive return of +29.4% for
the year ended June 30, 1999. The +32.5% annualized return since inception is in
excess of broad market averages. For example, the comparable S&P 500 return for
the same eighteen-month period was +27.8%

     The Fund lagged behind the Pacific Stock Exchange Technology 100 Index
(PSE) due to the Index's disproportionate contribution from Internet securities
and the Fund's commitment to the health care sector. At the end of June, health
care stocks represented 24% of the portfolio compared to an estimated 15% health
care weight for the Index. During the past twelve months, health care holdings
have averaged approximately 33% of the portfolio. While we believe there are
many promising long-term investments within the health care sector, these stocks
have lagged behind the technology sector performance within the Fund over the
last twelve months. This relative underperformance has led to compelling
valuations for health care issues, and the Fund will continue to pursue
opportunities in this sector.

     As of June 30th, the Fund was 99% invested in equity securities, up from
96% last year. The most significant sector change was related to a shift from
the technology services sector to the electronic technology sector. Since
lingering fears of a Year 2000-related slowdown may weigh down the performance
of technology service companies, total or partial sales were made in shares of
Computer Associates, Cadence Design, Intelligroup, Peoplesoft, and Security
Dynamics. Improving fundamentals in the telecommunications and semiconductor
industries led to increased weightings within the electronic technology and
utilities sectors through the purchase of Applied Micro Circuits, Jabil Circuit,
Motorola, Nokia, PMC-Sierra, Teradyne, Vitesse Semiconduictor, and MCI Worldcom.

     Earnings for the stocks in the Fund are expected to grow +26% in 1999 and
+32% over the next five years. Despite growth rates of more than two and
one-half times the market, valuations do not appear excessive. The
price-to-earnings ratio for the Fund currently stands at 39 times 2000 earnings,
and the comparable ratio for the S&P 500 is 26 times earnings. Based on the
strong earnings growth and attractive relative valuations, we continue to be
optimistic about the outlook for companies in the Fund.


                        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 DEVELOPING MARKETS GROWTH FUND REVIEW
YEAR ENDED JUNE 30, 1999

[PHOTO]  SENIOR PORTFOLIO MANAGERS
           EUGENE C. SIT, CFA
           ANDREW B. KIM, CFA

     During the June quarter, the Sit Developing Markets Growth Fund (up +29.1%)
outperformed both the MSCI Emerging Markets Free Index (up +23.6%) and the
Lipper Emerging Markets Index (up +25.2%), reflecting the sizable positive
returns of the holdings in the Asian markets. At the end of June, equity
holdings in Asia increased to 58.1% of the net assets vs. 41.3% for the Index.
Weightings increased sharply from a year ago in Taiwan (13.2% vs. 8.4%), South
Korea (11.9% vs. 3.7%), and Singapore (10.9% vs. 6.3%) because of a continued
focus on the electronics sector's contract manufacturers.

     The Fund's 1-year return, however, was less favorable increasing +10.3%
compared with the MSCI Emerging Markets Free Index benchmark gain of +25.2% and
the Lipper Emerging Market Index return of +19.0%. The underperformance relative
to the indices was in large part the result of our underweight in Mexico, South
Korea, and Greece as well as our lack of interest rate sensitive financial and
property sector exposures in Asia early in the year. Our exposure in some
non-index countries and our high cash position also hurt performance.

     The overall Latin American weighting as of June 30th stood at 15.5% vs.
30.4% for the Index. In Latin America, the Fund's holdings continue to be
concentrated in Mexico (11.3% vs. 11.9%) based on its promising corporate
earnings outlook. The removal of near-term uncertainties over immediate U.S.
interest rate increases and higher oil prices should benefit emerging markets in
general. Specifically, Mexico should more fully benefit from strong NAFTA
economies. Brazil, however, is substantially underweight (3.0% vs. the Index's
8.7%) due to structural weakness stemming from its domestic fiscal problems.

     Emerging-Europe, Middle East and Africa holdings were underweighted at
18.4% vs. 28.3%. The Fund continued to overweight Israel (4.4% vs. 2.9%) and
underweight South Africa (2.5% vs. 11.0%). Greece was the largest weighting
(7.1% vs. 6.1%).

     Among new additions in the Fund's holdings were Korea Telecom, Development
Bank of Singapore, Hana Microelectronics in Thailand, Comverse Technology in
Israel, Philippine Long Distance Telephone in addition to Delta Dairy in Greece.

     We believe the favorable liquidity conditions in Asia should continue in
the second half, aided by the increased current account surplus, foreign direct
investment, lower interest rates and stable currencies. In addition, we look for
Japan's improving business conditions and strong currency to contribute to
Asia's economic recovery.


                        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.

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, and Sit Science
and Technology Growth Funds are series funds of Sit Mutual Funds, Inc.

This report covers the equity funds of the Sit Mutual Funds (the Funds). The

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

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.

ILLIQUID SECURITIES

Each Fund currently limits investments in illiquid securities to 15% of net
assets. At June 30, 1999, the Developing Markets Growth Fund and Science and
Technology Growth Fund held investments in securities deemed illiquid by the
investment adviser. The aggregate value of such securities at June 30, 1999, was
$88,660 and $34,875, representing 0.8% and 0.2% 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, 1999, the Developing Markets Growth Fund had entered into a foreign
currency exchange contract that obligated 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:

DEVELOPING MARKETS GROWTH FUND:

                                                             Unrealized
      Exchange date    Currency to be    Currency to be     appreciation
                         delivered         received        (depreciation)

                      Canadian Dollar     U.S. Dollar

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.


                                                                              49

SIT MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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

Developing Markets Growth          5,540            33,292           (38,832)
Small Cap Growth                 493,500           (14,111)         (479,389)
International Growth             890,599        (1,054,304)          163,705
Mid Cap Growth                 1,585,981          (427,709)       (1,158,272)
Regional Growth                    5,833                --            (5,833)
Large Cap Growth                 116,734       (10,031,432)        9,914,698
Science and Technology Growth     63,669                --           (63,669)

The International Growth, Mid Cap Growth, and Small Cap Growth Funds elected to
utilize equalization debits by which a portion of the costs of redemptions,
which occurred during the year ended June 30, 1998, reduced accumulated net
realized gains for tax purposes by $163,703, $427,709, and $14,112,
respectively. In addition, included in the Large Cap Growth Fund adjustment is
$10,031,752 related to an in-kind distribution.

For federal income tax purposes the Developing Markets Growth Fund has a capital
loss carryover of $3,697,984 at June 30, 1999 which, if not offset by subsequent
capital gains, will begin to expire in 2004. Also at June 30, 1999, the Small
Cap Growth, Science and Technology Growth, and Regional Growth Funds have
capital loss carryovers of $3,899,846, $332,937, and $67,482, respectively
which, if not offset by subsequent capital gains, will begin to expire in 2007.
It is unlikely that the Board of Directors will authorize a distribution of net
realized gains until the available capital loss carryovers are offset or expire.

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.

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.

these voluntary fee waivers may be discontinued by the Adviser in its sole
discretion. During the period ended December 31, 1999, for the Mid Cap Growth,
International Growth, Regional Growth, and Science and Technology Growth Funds,

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 $681,189 were paid or
payable to SKI for the year ended June 30, 1999.

INDEPENDENT AUDITORS' REPORT


The Board of Directors and Shareholders
Sit Large Cap Growth Fund, Inc.
Sit Mid Cap Growth Fund, Inc.
Sit Mutual Funds, Inc.:

     We have audited the accompanying statements of assets and liabilities,
including the schedules of portfolios of investments in securities of Sit
Balanced Fund (a series of Sit Mutual Funds, Inc.), Sit Large Cap Growth Fund,
Inc., Sit Regional Growth Fund (a series of Sit Mutual Funds, Inc.), Sit Mid Cap
Growth Fund, Inc., Sit International Growth Fund (a series of Sit Mutual Funds,
Inc.), Sit Small Cap Growth Fund (a series of Sit Mutual Funds, Inc.), Sit
Science and Technology Growth Fund (a series of Sit Mutual Funds, Inc.), and Sit
Developing Markets Growth Fund (a series of Sit Mutual Funds, Inc.), as of June
30, 1999; the related statements of operations for the period ended June 30,
1999; the statements of changes in net assets for each of the periods in the
two-year period ended June 30, 1999; and the financial highlights as presented
in note 4 to the financial statements. These financial statements and the
financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform our audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased and sold but not received or delivered, we
request confirmations from brokers and where replies are not received, we carry
out other appropriate auditing procedures. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements and the financial highlights
referred to above present fairly, in all material respects, the financial
position of Sit Balanced Fund, Sit Large Cap Growth Fund, Sit Regional Growth
Fund, Sit Mid Cap Growth Fund, Sit International Growth Fund, Sit Small Cap
Growth Fund, Sit Science and Technology Growth Fund, and Sit Developing Markets
Growth Fund as of June 30, 1999 and the results of their operations, the changes
in their net assets, and the financial highlights for the periods stated in the
first paragraph above, in conformity with generally accepted accounting
principles.
