Russell Microcap® Index financial
"the Company’s common stock has been added to the Russell Microcap® Index following the 2026 Russell indexes reconstitution"
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.
Russell U.S. Indexes financial
"The reconstitution of the Russell U.S. Indexes captures the 4,000 largest U.S. stocks"
A family of U.S. stock market benchmarks that groups publicly traded companies by size and tracks their combined performance. Think of them as league tables that sort companies into tiers (large, mid, small) and measure how each tier is doing; investors use these indexes to compare fund performance, build passive funds or ETFs, and gauge which part of the market is strengthening or weakening.
diversified holding company financial
"Star Equity Holdings, Inc. ... a diversified holding company, announced today"
microcap segment financial
"The Russell Microcap® Index measures the performance of the microcap segment of the U.S. equity market"
benchmark financial
"used by institutional investors and investment managers as a benchmark for microcap equities"
A benchmark is a standard or yardstick—usually a market index, interest rate, or agreed performance target—used to measure how well an investment, portfolio, or fund is doing. It matters to investors because comparing returns against that benchmark shows whether a manager is adding value or simply matching market movements; like comparing a car’s mileage to an average, beating the benchmark suggests better performance while lagging suggests underperformance or higher costs.
