Momentum, money flow, and rate of change have been in downtrend since April of 2016, and have been especially depressed since June of this year, as shown on the following Weekly chart of Equifax (EFX).
 

The stock is down by 6.2% in after-hours trading tonight at 124.00 (horizontal red line in above chart), according to this Bloomberg tweet and report…
 

Its after-hours price of 124.00 puts it below its long-term uptrend line and the 50-day moving average of 131.50…a hold below that price, together with sharp drops in the above three technical indicators, could see price tumble further to, potentially, the 200 MA at 103.00.
