NYSE Composite Index (NYA)
The NYSE Composite (NYSE: NYA) is a stock market index covering all common stock listed on the New York Stock Exchange, including American Depositary Receipts, Real Estate Investment Trusts, tracking stocks, and foreign listings. Over 2,000 stocks are covered in the index, of which over 1,600 are from United States corporations and over 360 are foreign listings; however foreign companies are very prevalent among the largest companies in the index: of the 100 companies in the index having the largest market capitalization (and thus the largest impact on the index), more than half (55) are non-U.S. issues. This includes corporations in each of the ten industries listed in the Industry Classification Benchmark. It uses free-float market cap weighting.
In addition to the overall composite, there are separate indices for industrial, transportation, utility, and financial corporations.
The index is the basis of the iShares NYSE Composite Index Fund (NYSE: NYC), an exchange-traded fund.
