Sellers turned timid after bullying the futures down to within  three ticks of a key low at 885.00 recorded in mid-March.  The support looks much too obvious to work, and so we should prepare for more weakness this week down to at least 845.20, the Hidden Pivot given here last week as a minimum bear-cycle objective.  The midpoint sibling of that number is 907.60, but it is resistance now, and any rally that touches it is a good candidate for shorting with a tight stop-loss.
