AT&T [$T] 30 January 2019

Always beware of a stock that's down when the overall market is up substantially.  

It's often a telltale sign.  

Both the S&P500 and the DJIA were both up more than 1.5% while $T was down more than 4%.

The chart shows a long term bullish price pattern that failed.  It's not likely to repair itself.
