Final answer:
The Dow Jones Industrial Average, a price weighted average of 30 industrial stocks tracked on the NYSE, is the answer to the student's question. It represents a major stock market indicator alongside the S&P 500, which follows 500 large U.S. companies.
Step-by-step explanation:
The Dow Jones Industrial Average is an index based on the adjusted average price of stocks of 30 major corporations picked by editors of the Wall Street Journal. This index is widely recognized as one of the main indicators of the stock market performance in the United States. It is a price weighted average of the stock prices of the selected companies and is tracked on the New York Stock Exchange (NYSE).
Another well-known indicator, the S&P 500, tracks the stock prices of the 500 largest U.S. companies and is a weighted average market capitalization of these firms. Unlike the Dow Jones Industrial Average, the S&P 500 encompasses a broader range of companies, providing a more comprehensive look at the overall market.
