US2000 (Russell 2000 Index)
The US2000, commonly known as the Russell 2000 Index, tracks the performance of approximately 2000 small-cap companies in the United States. This index is a subset of the Russell 3000 Index and is widely considered a leading indicator of the performance of small-cap stocks in the U.S. stock market. The index is market capitalization-weighted, meaning companies with higher market caps have a larger impact on the index's price movement.
