Dow Jones Index
The Dow Jones Index is correctly names the Dow Jones Industrial Average and often abbreviated as DJIA. Its official symbol, however, is $INDU.
The Dow Jones Index is an index of the 30 large industrial stocks in the United States. The Dow Jones Index is unique among the popular indexes tracked in North America, Europe and Asia in that it is a simple average and not a weighted average like the others are. What this means is that the price of all the shares in the index are added together and then averaged to come to a figure which is then used to calculate the index value. Compare this to other popular indexes which are weighted averages. These other indexes weight the market capitalization of each constituent against the price when calculating their indexes.
