S&P 500 Index is ^SPX, are there other indexes on FAST Graphs?

Unfortunately we do not currently subscribe to the S&P Capital IQ Index database.
The database we subscribe to only provides earnings information on the S&P 500 index (^SPX).  
You can find price information on:
Russell 1000 Growth Index (^RLG)
NASDAQ Composite Index (^COMP)
Dow Jones Industrial Average (^DJI)

To search for other indexes, if you look right above the ticker box there is a question mark (?), click that on, look to the right where you will see “Keywords” and a search box, type in the word “index” click on the “Search” button and it will give you some options to choose from.  (Make sure the exchange setting is at “ANY exchange”)
