Russell 2000RUT

The Russell 2000 tracks around 2,000 small-capitalization US companies and is the most-watched benchmark for the small-cap segment of the market. Because smaller companies are more sensitive to the domestic economy and borrowing costs, it is often seen as a barometer of US economic health and risk appetite. It tends to be more volatile than large-cap indices like the S&P 500. Traders access it through ETFs, futures and CFDs. It can move sharply, so size positions carefully and manage risk.
