DJX is the symbol for options based on The Dow Jones Industrial AverageSM (DJIASM).
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 11,000, the DJX level will be 110. The DJIA - the index on which the DJX contracts are based - is the oldest (established 1896) continuing U.S. market index, and the DJIA probably is the world's best known stock index to individual investors. Options on the Dow are available from 8:30 a.m. to 3:15 p.m. CT.
Since their introduction in 1997, DJX options have grown to become some of the most popular index options worldwide.
