New York Stock Exchange Composite Index

Definition

The New York Stock Exchange Composite Index (NYSE Composite Index) is a market-value-weighted index that includes all common stocks listed on the New York Stock Exchange (NYSE). The index aims to provide a comprehensive measure of the performance of the entire NYSE market, capturing nearly the full range of industries and sectors represented by NYSE-listed companies.

Market-Value-Weighted

In a market-value-weighted index, each stock’s impact on the index’s performance is proportional to the market value (or market cap) of its outstanding shares. Larger companies have a greater influence on the index’s movements compared to smaller ones.

Examples

Large-Cap Stocks: Companies such as ExxonMobil, Coca-Cola, and JPMorgan Chase are significant components of the NYSE Composite Index due to their high market capitalization.
Mid-Cap and Small-Cap Stocks: While larger companies have more influence, the index also includes mid-cap and small-cap stocks, which contribute to the performance measurement of the entire NYSE.
Sector Representation: The NYSE Composite Index comprises various sectors including technology, healthcare, financial services, consumer goods, and industrials.
