Russell 2000® Index financial

"it has been added to the Russell 2000® Index and the broader Russell 3000® Index"

A stock market index that tracks the performance of roughly 2,000 publicly traded U.S. companies with smaller market values, representing the broader small-cap segment of the market. It matters to investors because it acts like a thermometer for smaller companies—used as a benchmark to compare fund performance, guide portfolio allocation, and gauge economic or market trends affecting growth-oriented, higher-risk firms.

Russell 3000® Index financial

"it has been added to the Russell 2000® Index and the broader Russell 3000® Index"

A broad stock market index that tracks the performance of about 3,000 publicly traded U.S. companies of all sizes, acting as a wide-ranging snapshot of the U.S. equity market. It matters to investors because it serves as a common yardstick for the overall market’s health and is the basis for many index funds and investment strategies—think of it as a single basket that shows how the whole U.S. stock market is doing.

Russell Microcap® Index financial

"Innventure has been included in the Russell Microcap® Index, which measures the performance"

A market index that tracks the performance of the smallest publicly traded U.S. companies by market value, the Russell Microcap® Index acts like a thermometer for the microcap segment of the stock market. Investors use it as a benchmark to measure how tiny, often more volatile firms are performing relative to broader markets, helping with portfolio allocation, risk assessment and comparing the returns of funds focused on very small-cap stocks.

index funds financial

"used by investment managers and institutional investors for benchmarking and as the basis for index funds and ETFs"

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.

ETFs financial

"used by investment managers and institutional investors for benchmarking and as the basis for index funds and ETFs"

ETFs, or exchange-traded funds, are investment funds that hold a collection of stocks, bonds, or other assets, and can be bought or sold on stock exchanges like individual shares. They offer investors an easy way to diversify their holdings and access different markets or sectors without buying multiple individual assets. Because they are traded throughout the day, ETFs provide flexibility and can help investors manage risk while pursuing their financial goals.

market capitalization financial

"Membership in the Russell indexes ... is determined primarily by market capitalization and style attributes"

Market capitalization is the total market value of a company’s outstanding shares, calculated by multiplying the current share price by the number of shares issued. It gives a quick snapshot of a company’s size and how investors value it, influencing perceived risk, index membership, and roughly how much it might cost to buy the whole company — like using a sticker price to compare the relative size and price of different houses.
