Since late July, the price of American Express has been in the 150-165.5 range.
Yesterday's hammer, also with a gap, just below the 150 level neatly hints at the prospect of the stock rising above 150 to the 165.5 level and closing the gap.
The company's July quarterly report was good, as was the outlook for the next quarter, and upside potential remains.
DeMarker is in oversold zone, which also suggests that the stock is about to resume rising.
In addition to all that, today is Friday, a great day to trade at the close of the day.
