russell 2000® technical

"it will be added to the Russell 2000® and Russell 3000® Indexes"

The Russell 2000® is a stock market index that tracks the performance of about 2,000 smaller publicly traded U.S. companies, serving as a broad snapshot of the small-cap segment of the market. Investors use it like a thermometer for smaller businesses—if it rises or falls, it signals how that group is doing overall and helps compare or benchmark investment funds and risk exposure to smaller-company stocks.

russell 3000® technical

"it will be added to the Russell 2000® and Russell 3000® Indexes"

A stock market index that tracks the performance of the largest 3,000 publicly traded U.S. companies, representing roughly the entire U.S. equity market. It matters to investors because it serves as a broad “shopping cart” or market thermometer—used as a benchmark to judge how well portfolios or funds are doing, and as the basis for many index funds and ETFs that aim to mirror overall market performance.

ipo financial

"as part of FTSE Russell's first quarter Initial Public Offering (IPO) addition"

An initial public offering (IPO) is the process by which a private company sells its shares to the public for the first time, making its ownership available on the stock market. This allows the company to raise money from a wide range of investors to fund growth or other goals. For investors, an IPO offers a chance to buy into a company early in its public journey, potentially benefiting if the company grows in value.

View in glossary

index funds financial

"used by investment managers and institutional investors for index funds and as benchmarks"

A fund that pools investors’ money to buy the same collection of stocks or bonds that make up a market index — like a ready-made basket representing the whole market or a specific slice of it. It matters because it gives broad exposure with lower fees and simpler management than picking individual securities, reducing the impact of any single holding and making it efficient for long-term investing.

benchmarks financial

"used by investment managers and institutional investors for index funds and as benchmarks"

Benchmarks are standard measures—often broad market indexes or preset targets—used to judge how well an investment, fund or strategy is performing compared with a common yardstick. Like timing runners against the lead car in a race, benchmarks help investors see whether returns come from skill or simply following the market, guide portfolio choices, reveal added risk or costs, and set realistic performance expectations.
