The Dow Jones Industrial Average (DJIA) was compiled by The Wall Street Journal and Charles? One of several stock market indexes founded by Dao.
He regards this index as an indicator to measure the development of the industrial composition of the American stock market, and it is one of the oldest American market indexes.
Today, the average index includes 30 largest and most famous listed companies in the United States. Although the word "industry" is mentioned in the name, its historical significance may be more than the reality-because most of today's 30 constituent enterprises have nothing to do with heavy industry.
Due to the influence of compensating stock split and other adjustments, it is only a weighted average at present and does not represent the average of constituent stocks.
The Standard & Poor's Index, also known as the Standard & Poor's Stock Price Composite Index, was compiled and published by Standard & Poor's Company in 1957, and the base index was also 100. Standard & Poor's Company is the largest securities research institution in the United States, and began to compile and publish the stock price index on 1923.
In recent years, many experts believe that the Standard & Poor's index is superior to the Dow Jones index. Jones index can more truly reflect the actual situation of the stock market (similar to China CSI 300 Index): First, the S&P index contains a wide range of stocks, including the total value of 500 stocks, accounting for about 90% of the total value of stocks listed on NYSE, which can fully reflect the changes of stock market prices; Second, the standard & poor's index is randomly sampled, including three stocks; Third, the Standard & Poor's index is calculated with the trading volume of stocks as the weight, and there is no need to adjust the analyzed stocks.
But the Standard & Poor's index can't replace the Dow Jones index, which is still widely used by most securities companies, newspapers, magazines, TV broadcasts and other media.
NASDAQ (National Association of Securities Dealers Automated Quotas) is the English abbreviation of the name of the automated quotation system created by the National Association of Securities Dealers in the United States in 1968.
The Nasdaq index is characterized by collecting and publishing quotations from securities companies that trade unlisted shares over the counter. It has now become the largest stock exchange market in the world. At present, there are more than 5,200 listed companies. Nasdaq is the first stock market in the world to adopt electronic trading, with more than 260,000 computer sales terminals in 55 countries and regions.
Nasdaq index is an average stock price index reflecting the changes of Nasdaq stock market, and its basic index is 100.
Nasdaq's listed companies cover all new technology industries, including software and computers, telecommunications, biotechnology, retail and wholesale trade.
When NASDAQ was founded, listing on the main board (preferably new york Stock Exchange) obviously enjoyed a higher reputation than trading on NASDAQ. Most of Nasdaq's stocks are newly listed small companies or small companies or new companies, which cannot meet the requirements of listing on large stock exchanges.
However, many young high-tech companies think that Nasdaq's computer system is a more natural place. Even though many companies like Intel and Microsoft met the requirements, they did not choose to go to the "main board" like NYSE.
