...Also since we like bigger numbers, the Dow rallied 500 points sounds better than the S&P is up 40 points. That doesn't mean anything for the average people...
But in futures it is concomitant. YM goes up 500 points it is $2,500 per contract. ES goes up 40 points and it is $2,000 per contract. There is some relevancy there. The amount of money to be made on each is very similar. As for which leads which? Tough call there.
