The S&P 500 challenged (2756.55) at the opening the lower boundary of the resistance area (2750-2800) we mentionned in our previous comments before retreating under some selling pressure later in the day. The trading range may expand over the next few days between 2680 and 2750 at the approach of the mid term election and the continuing uncertainty surrounding the negociations behind a closed door of a potential trade deal between the US and China.
