There are many “models” used to measure the pulse of the United States stock market. Below are some of them. There are over 6,000 stocks traded over the New York stock exchange (NYSE). Here’s a laundry list of some of the U.S. stock markets indices. Each index contains a different “sampling” of stocks, however, any one stock can be listed in more than one index “basket”, e.g. Apple is traded on the NASDAQ market and is also included on the Dow Jones Industrial Index of 30 stocks. To be clear, the NASDAQ is a stock trading market place and the Dow Jones Industrial Average is a listing of 30 stocks.
New York Stock Exchange (NYSE)
“A stock exchange based in New York City, which is considered the largest equities-based exchange in the world based on total market capitalization of its listed securities. Formerly run as a private organization, the NYSE became a public entity in 2005 following the acquisition of electronic trading exchange Archipelago. The parent company of the New York Stock Exchange is now called NYSE Euronext, following a merger with the European exchange in 2007.”

Dow Jones Industrial Average (DJIA)
“The DJIA is a price-weighted index, which means that the sum of the component stock prices is divided by a divisor. Instead of dividing by the number of stocks in the average, as is done in an arithmetic average, the Dow divisor is used. The purpose of this divisor, which is continually adjusted, is to smooth out the effects of stock splits and dividends. The result is that the DJIA is affected only by changes in the stock prices, so stocks with a higher share price have a larger impact on the Dow’s movements.
For example, if the DJIA rose by 50 points, it means that the cost of purchasing the 30 stocks in the index was $50 higher than the cost of purchasing those same 30 stocks yesterday, taking into account stock splits and dividends. In other words, those stocks are more valuable today than they were the previous day. Over time, the DJIA can be used as a benchmark for the economy.” Read more: What does the Dow Jones Industrial Average measure? | Investopedia http://www.investopedia.com/ask/answers/050115/what-does-dow-jones-industrial-average-measure.asp#ixzz3xk41bg3f
