Since successfully retesting support in the $150s last month, American Express (AXP) has been under renewed accumulation. Starting with a high-volume bounce that regained the 50-day average, the shares had been climbing within their previous $150-$185 range for several days, snapping a downtrend line along the way. Yesterday the shares blasted through the top of the channel to a new all-time high, signaling the start of a new advance and the end of a consolidation phase.
