Trader Brian Jones on Twitter: "The S&P hasn't hit negative last 2 days. So with futures up 35-40 after hours. I think you have to take some profits just like I said to do premarket at up 86 on S&P. The S&P could easily go Negative sometime tomorrow." / Twitter

The S&P hasn't hit negative last 2 days. So with futures up 35-40 after hours. I think you have to take some profits just like I said to do premarket at up 86 on S&P. The S&P could easily go Negative sometime tomorrow.
