Mate futures has all the information discounted along with the upcoming news and stuff better than the cash. Futures contract is the best indication of the up coming market situation. Do you know why people write calls and why they write puts? I am not talking about naked positions or in trading terms speculative positions. Also what you say is clearly suggesting whenever the smart money is ready to take a huge position they will do so by entering in the futures contract first and later in the cash that is all I am trying to say here. Futures market can give you the indication of where are market is going to head in the short term.
