Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, U.S. small-cap stocks gained ground broadly, fueled by optimism that the Federal Reserve may be able to end its interest-rate hiking cycle without tipping the economy into recession. In this environment, we felt investors began to recognize company-specific fundamentals. These market conditions were favorable for the Fund and our investment approach. Our guiding investment principle is that over longer time horizons, stock prices tend to follow earnings growth. As such, the primary investment technique the Fund employs is to conduct deep, fundamental research to find high-quality, durable growth companies within the small-cap universe. Over the period, many of our companies produced strong operating results, and the market seemingly recognized those fundamentals. The Fund outperformed the benchmark Russell 2000 ®

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, India’s economy remained one of the strongest in the world, and enthusiasm about economic growth drove India’s major stock indexes to record highs. A growing consensus that central banks were nearing or reaching the end of their tightening cycles also created a favorable backdrop for financial markets. While the Fund had a significant gain during the period, it underperformed the benchmark MSCI India Investable Market Index (IMI). Our holdings in the consumer-discretionary sector were a bright spot, substantially outperforming the benchmark’s holdings in the sector. An overweight to health care was also beneficial to relative results. Underperformance was largely due to stock selection within the financial sector. High interest rates and increased capital requirements made lending more costly, in part pressuring profit margins. This weighed on some financials stocks, which remain a significant part of our portfolio. Additionally, our holdings in the materials and industrials sectors generally had solid gains but trailed the benchmark’s positions. Many of the benchmark’s holdings in those sectors tend to be more cyclical than our own. Given the strength of India’s economy, some of the more cyclical stocks outperformed.

A growing consensus that central banks were near the end of their tightening cycles was also favorable for markets. While the Fund had significant gains, it underperformed the benchmark MSCI Emerging Markets Index. Much of the underperformance was due to stock selection in Taiwan, where the Fund didn’t hold some of the higher-returning stocks in the benchmark. Additionally, given the concentrated nature of the portfolio, the Fund’s performance relative to its benchmark came down to a few stocks. The Fund’s largest detractors included Wuxi Biologics Cayman, Inc., a China-based contract research, development and manufacturing organization; DLocal Ltd., a Uruguay-based fintech firm; and Yifeng Pharmacy Chain Co. Ltd., a retail drugstore operator in China. While those stocks negatively impacted performance, we were pleased with the results of many of our other companies. Top contributors included Nu Holdings Ltd., a Brazilian company operating a fintech bank in Latin America; MercadoLibre, Inc., which operates a Latin American e-commerce platform; and Trent Ltd., an Indian retailer.

Stock selection in India was a bright spot for relative performance as well. Overweight positioning in Mexico was the Fund’s biggest source of underperformance. In the latter half of the period, stocks in Mexico sold off broadly as investors reacted to the Morena Party’s resounding victory in national elections. Investors were concerned the winning party could use its mandate to brush aside some checks on presidential power. Among sectors, stock selection in the financials sector weighed on relative results, while stock selection in the consumer-discretionary sector contributed.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, a growing consensus that central banks were nearing or reaching the end of their monetary tightening cycles created a favorable backdrop for financial markets. In that environment, investors stepped out on the risk spectrum and embraced stocks in frontier and emerging markets, driving these markets higher. The Fund outperformed the benchmark MSCI Frontier Emerging Markets Index. Many of our companies produced strong fundamentals during the year, and their stock prices were up significantly as investors began to appreciate the strong earnings growth these companies produced. Stock selection in Vietnam was a large driver of outperformance relative to the benchmark. While we were generally pleased with the Fund’s performance relative to the benchmark, our underweight to Peru detracted from relative results. Peru was one of the top-performing components within the benchmark during the period. We have a small weight in Peru because we’ve found what we believe are better growth opportunities elsewhere.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, a growing consensus that central banks were nearing or reaching the end of their monetary tightening cycles created a favorable backdrop for financial markets. In that environment, investors stepped out on the risk spectrum and embraced stocks in frontier and emerging markets, driving these markets higher. The Fund outperformed the benchmark MSCI Frontier Emerging Markets Index. Many of our companies produced strong fundamentals during the year, and their stock prices were up significantly as investors began to appreciate the strong earnings growth these companies produced. Stock selection in Vietnam was a large driver of outperformance relative to the benchmark. While we were generally pleased with the Fund’s performance relative to the benchmark, our underweight to Peru detracted from relative results. Peru was one of the top-performing components within the benchmark during the period. We have a small weight in Peru because we’ve found what we believe are better growth opportunities elsewhere.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, the period was marked by some uncertainty about geopolitical tensions, elections in several key countries and mixed economic data. But the period overall was buoyed by an increasingly optimistic view that the U.S. Federal Reserve (Fed) and other central banks were at or near the end of their monetary tightening cycles. In September, the Fed followed through on investor expectations, lowering its benchmark interest rate for the first time since 2020. Late in the period, China’s government announced a series of stimulus measures to revive its struggling economy, and those measures were well received by the market. In this environment, the Fund outperformed the benchmark MSCI AC (All Country) World Small Cap Index. Among the Fund’s high-quality, high-conviction companies, its holdings in the U.S.—its largest portfolio weight—contributed the most to performance relative to the benchmark, followed by Israel and Taiwan. On the other end of the spectrum, the Fund’s holdings in the United Kingdom and India were notably weaker than those of the benchmark and detracted from performance.

During the 12 months ended September 30, 2024, global equities experienced large gains. Hopes that many central banks may be at or nearing the end of their monetary tightening cycles helped drive stocks higher. While the Fund had substantial gains during the period, it underperformed the benchmark MSCI AC (All Country) World Index. Much of the underperformance was due to stock selection in the U.S. While many of the Fund’s U.S. holdings had what we considered solid returns, the Fund’s U.S. component lagged the benchmark’s. Additionally, given the Fund’s concentrated nature, its performance relative to the benchmark can often be attributable to just a few stocks. The Fund’s largest detractors included Five Below. Inc., a U.S. retailer; JMDC, Inc., a Japan-based medical-data provider; and Bajaj Finance Ltd., an Indian financial company. While those stocks negatively impacted performance, we were pleased with the results of other holdings. Top contributors included Amphenol Corp., a U.S. manufacturer of connectors and sensors; MercadoLibre, Inc., which operates a Latin American e-commerce platform; and Monolithic Power Systems, Inc., which designs and manufactures power-management solutions, including power-conversion devices.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, the world economy continued to expand despite the past interest-rate hikes from leading central banks. In addition, the U.S. Federal Reserve (Fed) continued to signal that it could begin cutting rates in 2024, bolstering hopes of avoiding a recession. In September, the Fed joined other major central banks in loosening policy, enacting a half-point rate cut. Not long after, China announced plans for massive monetary stimulus to kick-start its economy, further boosting equities. Overall, the Fund’s defensive, quality-focused positioning was a headwind in a market where investors focused on growth stocks. We remain focused on relatively inexpensive, lower-volatility stocks of larger-cap companies with high free cash flows, strong balance sheets and attractive dividend yields. During the period, the Fund’s U.S. holdings detracted most from performance relative to the benchmark MSCI AC (All Country) World Value Index, while our Taiwan names contributed the most. Health care and information technology were also relatively weak performers for the Fund, while consumer discretionary and communication services were beneficial.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, investor sentiment toward China remained low for much of the period due to concerns about a real-estate bubble and a softening economy. However, in September, government leaders and central-bank officials announced economic-stimulus measures designed to stabilize China’s real-estate market. Their moves ignited broad gains in Chinese equities. For much of the period, China was a value-driven market. Investors generally favored inexpensive stocks, which tend to be lower-quality companies and don’t appeal to us as quality growth investors. Additionally, large-caps also outperformed for much of the period. This too was a headwind for our strategy, which primarily focuses on small- and mid-cap companies. We seek businesses with strong balance sheets and earnings growth greater than their sector and industry. Over time, we expect the superior earnings growth of our companies to drive greater returns compared to the benchmark MSCI China Index. Our approach didn’t result in outperformance this period, as the market generally rewarded the largest, lowest-priced stocks, not those with the strongest fundamentals. On November 13, 2024, the Board of Trustees of the Wasatch Funds Trust approved a plan of liquidation for the Wasatch Greater China Fund to close the Fund and redeem all of its outstanding shares on or about January 15, 2025.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, international equities experienced large gains. Hopes that many central banks may be nearing the end of their monetary tightening cycles helped drive stocks higher. While the Fund had significant gains, it underperformed the benchmark MSCI AC (All Country) World ex USA Small Cap Index. The underperformance was largely due to our stocks in India and Japan. Within India, most of our stocks had solid gains, but we didn’t hold some higher-returning Indian stocks in the benchmark index. Within Japan, a value-oriented market that also favored large-cap stocks presented style headwinds for our small-cap growth strategy. While those stylistic trends in Japan were a headwind for our relative performance during much of the period, those headwinds began to abate in the third quarter of 2024. Given the strong fundamentals many of our Japanese businesses have produced, we like the return potential of these stocks going forward, particularly if stylistic trends are no longer a headwind.

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? During the 12 months ended September 30, 2024, small-caps were up sharply, supported by a consensus view that the U.S. economy may achieve a soft landing and that interest-rate cuts could soon be on the way. The Federal Reserve eventually met those expectations when it lowered its benchmark federal-funds rate in September. We seek to invest in a carefully considered combination of longs and shorts, aiming to reduce risk and keep the Fund’s volatility lower than that of the benchmark. As might be expected in the period’s strong up market, the Fund’s long positions drove its return, and it outperformed the benchmark Russell 2500™ Index—despite an overall loss from the portfolio’s short positions. Among industry groups, the Fund’s long positions posted gains in all but two segments, with the highest contributions coming from pharmaceuticals biotechnology & life sciences and health care equipment & services. On the short side, performance among industry groups was mixed, with capital goods and consumer services detracting the most.

We also seek companies with innovative products or services, or those that utilize new technologies to do things better, faster and cheaper. Some of these companies accounted for our strong stock selection in health care—particularly in pharmaceuticals and biotechnology—which contributed the most, by a wide margin, to the Fund’s performance relative to the benchmark Russell 2000 ®

But optimism largely prevailed as the period progressed and the likelihood of rate cuts grew stronger, creating a favorable environment for U.S. equities. The Fund focuses on identifying high-quality small companies with strong growth prospects and solid fundamentals. We also seek companies with innovative products or services, or those that utilize new technologies to do things better, faster and cheaper. Some of these companies accounted for our strong stock selection in health care—particularly in pharmaceuticals and biotechnology—which contributed the most, by a wide margin, to the Fund’s performance relative to the benchmark Russell 2000 ®

Factors Affecting Performance [Text Block]	How did the fund perform last year and what affected its performance? Invested in long-dated U.S. Treasury securities, the Fund benefited from lower yields during the 12 months ended September 30, 2024, and outperformed the benchmark Bloomberg U.S. Aggregate Bond Index. Thirty-year Treasury bond yields closed at 4.13% at the end of September, down from 4.71% a year ago. The Fund’s managers position it in long-dated bonds when they expect inflation to fall, which happened over the period. Treasury yields decreased over the Fund’s fiscal year as three significant measures of inflation decreased during the period. Over the 12-month period, the overall Consumer Price Index (commonly called “headline CPI”), core CPI (which excludes volatile food and energy prices) and headline CPI excluding shelter increased by 2.4%, 3.3% and 1.1%, respectively. These levels were substantially below their respective numbers of 3.7%, 4.2%, and 2.0% for the twelve months ended September 30, 2023. Shelter is widely considered to lag current changes in inflation, and thus, its exclusion provides a far better indication of actual inflation. Inflationary expectations are the primary fundamental determinant of long-term Treasury bond yields. Inflation receded since the real and detrended broad money supply has declined over the last four years, and the rise of inventory investment in the first half of 2024 indicated an increased supply of goods.
