This is the nastiest break we’ve seen in two months, and we should treat it as though it were a possible resumption of the Mother of All Bears.  The low of yesterday’s plunge slightly exceeded a 0.618 retracement of the rally leg begun in mid-December, creating a bearish impulse leg on the 240-minute chart in the process. This is doubly bearish and suggests the selling has yet to even warm up. There are no useful Hidden Pivot targets that I can offer you at the moment, but I’d suggest using 1139.25 on the 240-minute chart for a point ‘A’ when the down-pattern now evolving develops a usable corrective rally.
