Dow & S&P Futures...Do you Know..

So, this is a simple question… Before the stock market opens, on CNBC and on the news you hear them qoute the DOW and S&P Futures being either up or down that may give clues for how the market will perform for that day.

I never thought which futures contracts they refer to… in other words are they the 1 month futures contract, 3 month futures contracts, etc… Any help would be appreciated. Thanks

Good question, I didn’t know and was curious myself, here’s what I found:

"Futures based on June 2014 contract.

Fair value provided by IndexArb.com"

The closest one. Index futures have 4 time periods (March, June, September, December).
