What is DJX?
DJX is the symbol for options based on The Dow Jones Industrial Average (DJIA). The DJIA is a price-weighted index of 30 of the largest, most liquid NYSE and NASDAQ listed stocks. The DJX index option contract is based on 1/100th (one-one-hundredth) of the current value of the Dow Jones Industrial Average. So, for example, when DJIA is at 10,000, the DJX level will be 100. The DJIA–the index on which the DJX contracts are based–is the oldest (established 1896) continuing U.S. market index. It is called an “average” because it originally was computed by adding up stock prices and dividing by the number of component stocks. The methodology remains the same today, but the divisor has been changed to preserve historical continuity. The DJIA is perhaps the best-known market indicator in the world.
