Industrial Dow Jones - stock indexes themselves thirty shares of large US companies.Created was the chief editor of the newspaper The WallStreetJournal Charles Dow in 1884 and was originally used only for internal analysis closed.
The realities of today's market, the Dow Jones industrial name only a tribute to history, because the majority of the members included in its calculation are not full uchasnikami shook off this.
Initially the index was calculated as the arithmetic mean between the prices of the shares of all participants.Now it's a little different.The sum value of all shares on a specific subgroup, which is constantly changing Corgi present in the rating companies are broken up or merge.The index was first published in the late nineteenth century, in 1896.It consisted of twelve major industrial US companies at the time.To this day the index of the oldest companies were only "General Electric".The company left this elite club is only in the early twentieth century, for several years, and after it is a permanent member.
After 1928, when the number of companies participating in the index was 30, the number peaked and will not change.Continuous rotation involves the replacement of one - two companies, but during the severe economic shocks related to the events, which are called "the great American depression", immediately flew from 7-8 companies ranking calculations.There were several periods when participants rating remained unchanged during the seventeenth and eighteenth let.Byli these two periods from the beginning of the forties to the mid-seventies.
first published rating stood at just under 41 points.The first thousand was achieved only in the mid-sixties.In the nineties, when the US was just crazy industrial growth index reached from the label in 5000, and in 1999 already 10 thousand points.At the beginning of the two thousandth growth index has fallen markedly, especially noticeable was just after the terrorist attacks in New York.
Among the shortcomings of the index point out that it gives only the average price of shares without comparison with the base value, because the index can be compared only with other similar value.But coverage is only 30, and let themselves large companies do not give a clear idea about the mood in the market.
priced in the index at the moment there are such world-known companies as "Coca-Cola", "Disney," "Boeing", "McDonald's" and many others.
Despite the index "Dow Jones" remains the oldest and most respected of all the world's known stock price, and its stable rating is a global barometer of economic stability.
