WHICH MARKET HAS MORE WEIGHT

Last week the cash market ended the day in the green conversely the futures market ended the day in the red I would like to hear from the veteran traders here which market has more weight for the opening on Monday and if so what percentage value would you place on each market. Thank You

The futures market definitely has a huge impact on the stock itself. However, to see which impact has on what takes some experience and actually the futures market might not even effect the stock market it is all speculation my good man.

I should have been more clear about my question. when I said the future market I meant the symbole @es. for the cash the symbole $inx

nothing to do with stocks
