A stock market index measures the performance of a group of stocks that represent a specific segment of the market. Indices serve as benchmarks for investors to gauge overall market performance, compare investment returns, and understand market trends. The three most widely followed U.S. indices are the S&P 500 (large-cap), NASDAQ-100 (technology-heavy), and Russell 2000 (small-cap).
The benchmark for large-cap U.S. equities
Tracks 500 of the largest publicly traded companies in the United States by market capitalization. Covers approximately 80% of available U.S. market cap. Rebalanced quarterly by S&P Dow Jones Indices committee.
The technology-heavy growth benchmark
Composed of the 100 largest non-financial companies listed on the NASDAQ exchange. Heavily weighted toward technology, consumer discretionary, and healthcare sectors. Known for capturing innovation-driven growth.
The small-cap economic barometer
Measures the performance of approximately 2,000 small-cap U.S. stocks. More sensitive to domestic economic conditions than large-cap indices. Reconstituted annually in June by FTSE Russell.
Compare your portfolio returns against the major indices to understand whether your investment strategy is outperforming or underperforming the broader market.
Index constituent breakdowns reveal sector weightings and concentration risk. For example, the S&P 500 is heavily weighted toward technology, while the Russell 2000 offers broader sector diversification.
Sorting index constituents by MoonshotScore shows which companies have the strongest figures within a benchmark. MoonshotScore V2 rates eligible US-listed companies from 0 to 100 against their sector peers on five pillars: Business Quality (weight 26), Financial Safety (weight 20), Valuation (weight 18), Growth Durability (weight 16) and Momentum (weight 12). It reads no news-sentiment or analyst data, and it is not a probability of future returns.
Understanding which index your holdings belong to helps assess your exposure to large-cap stability (S&P 500), growth volatility (NASDAQ-100), or small-cap cyclicality (Russell 2000).

Each price is the last quote we recorded, shown with the trading session it belongs to. Pages are served from a cache, so the copy you are reading can lag that quote. Each quote is a provider snapshot, not an exchange feed. MoonshotScore ratings are recalculated periodically based on the latest available financial data, earnings reports, and market conditions.
Index constituents represent established, liquid companies, but they are not the only investment universe. Many high-growth opportunities exist outside major indices.

Large-cap stocks (S&P 500) generally have market capitalizations above $10 billion, mid-cap between $2-10 billion, and small-cap (Russell 2000) between $300 million-$2 billion. Large-caps tend to be more stable, while small-caps offer higher growth potential with increased volatility.
