American Express has fallen below 1st standard devations from quarterly (66-day) and yearly (264-day) means, thus entering short term downtrend
Price is also trading within 1-st standard deviation from 10-year (520-week) and 5-year (260-week) moving averages, meaning that it is in lateral trend on long term basis
If the short term downtrend holds (price trading below 76.4-77.1 levels), there is a high probability to tag 5-year mean at 75 level
Scenario is canceled, if price returns to trend on 10-year basis by spiking above 1st standard deviations from 10-year mean (above 80)
