Russell 1000 & Russell 2000
The Russell 1000 tracks the largest ~1,000 US companies; the Russell 2000 tracks the next ~2,000 and is the most-followed small-cap benchmark.
The Russell indexes, maintained by FTSE Russell, slice the US market by size. The Russell 1000 holds the roughly 1,000 largest US companies (large- and mid-cap); the Russell 2000 holds the next roughly 2,000 (small-cap). Together they form the Russell 3000, which captures about 98% of the investable US stock market.
The Russell 2000 is the benchmark most investors mean by "small caps." Small-cap companies can grow faster than mega-caps but tend to be more volatile, more sensitive to the domestic economy and interest rates, and less widely covered by analysts. The index is rebalanced once a year, which can cause noticeable buying and selling as membership changes.
stocks-llm covers the Russell 1000 and 2000, which is what extends the catalog well beyond the mega-caps into small-cap names. The live list below shows Russell 2000 (small-cap) members in the catalog by market cap, as delayed data with its as-of date.
