NYSE Composite is one of the most comprehensive and overlooked stock market indexes out there. In a news cycle dominated by indexes such as the S&P 500 and Dow Jones Industrial Average, the N,YSE Composite gives investors a much more expansive look at how stocks are performing across thousands of companies-from large cap to small cap, which are listed on various exchanges around the globe.
For these global investors, financial analysts and economists, and not least of all long-term portfolio managers, the N,YSE Composite is more than just a number—its sucking wind says something about the macro-level health of capital flows into and out of being invested in risk assets, i.e., equity. This article will give you a complete breakdown of the N,YSE Composite Index, including what it is, how it functions compared to other indices, and why that even matters in today’s global financial markets.
The Role of the NYSE Composite Index
The N,YSE Composite Index is a market-capitalization-weighted index that includes all common stocks listed on the New York Stock Exchange, including ADRs, REITs, and tracking stocks. That includes American companies and foreign firms that elect to have their shares listed on the NYSE.
Debuted in 1966, it was intended to portray the NYSE in total rather than overweighting a relatively small sub-group of big and/or important companies. It was first valued at 50 points in 1965 and has grown as global equity markets expanded.
Key Components of the N,YSE Composite:
Includes 2,000+ listed companies
Covers large, mid and small-cap stocks
Represents multiple countries and currencies
Adjusted for free-float market capitalization
Due to the large size and scope of the index, many consider it one of the best representations of the stock market as a whole.
Calculating the NYSE Composite Index

This methodology helps the index represent actual investable market value and proves especially useful to institutional investors and fund managers.
Adjustments Include:
Stock splits and reverse splits
Mergers and acquisitions

Corporate restructurings
The methodology gives the index a natural life such that it changes smoothly based on what is happening in the market while maintaining long-term consistency.
